5 Game-Changing Skincare Trends Every Formulator Should Know in 2026
Skincare is evolving faster than ever, with fresh ideas transforming how we care for our skin. From personalised formulations to nature-inspired actives, exciting shifts are creating new possibilities for brands and independent formulators alike.
What's driving these trends? Sometimes it's scientific breakthroughs or traditional beauty rituals gaining global attention. Other times, it's innovators like you – small-batch creators experimenting with unique botanicals and listening closely to their customers.
The best part? As a formulator, you're not just watching these trends unfold. You're in a powerful position to harness them, creating products that feel fresh, meaningful, and deeply aligned with your customers' needs.
Today, we're exploring five game-changing trends shaping skincare right now – and how you can use them to craft distinctive products that stand out in 2026.
1. Waterless Wonders: Concentrated Innovation
The waterless beauty movement is perhaps the most exciting trend for DIY & business formulators. Traditional skincare products are often 70–80% water, which brings challenges such as shorter shelf life, bulky packaging, and the need for stronger preservatives.
The innovation opportunity is that waterless formulations eliminate these limitations entirely. Think of concentrated cleansing tablets that transform into gentle cleansers when mixed with water, or solid shampoo bars that deliver the same performance as liquid versions.
Benefits for your formulations:
Extended shelf life without harsh preservatives
Reduced packaging and shipping costs
Higher concentration of active ingredients
Sustainable appeal for eco-conscious consumers
Getting started: Begin with simple anhydrous formulations like body butters, cleansing balms, or solid moisturiser bars. These teach you the fundamentals of working without water while creating products your customers will love.
2. Local Botanicals: Your Backyard Luxury
Here's a formulation secret: what's local to you is luxurious to others. The trend towards local ingredients isn't just about sustainability. It's about harnessing the unique properties of plants that have adapted to your specific environment.
Why local ingredients work: Australian herbs like Kakadu plum, desert lime, and native pepperberry have evolved in harsh conditions, developing powerful protective compounds. When you incorporate these into your formulations, you are offering something truly unique.
Your body and local plants share the same environment. They face the same UV exposure, humidity levels, and seasonal changes. This means local botanicals often provide exactly what your skin needs to thrive in your climate.
Trending Australian botanicals to explore:
Kakadu Plum: Highest natural source of Vitamin C globally
Desert Lime: Natural AHA properties for gentle exfoliation
Native Pepperberry: Antioxidant-rich with conditioning properties
Lemon Myrtle: Natural antimicrobial properties for cleansing formulations
Wattle Seed: Rich in proteins and minerals for nourishing treatments
Formulation tip: Create regional signature blends. A "Daintree Forrest" face mist or "Blue Mountains" body oil tells a story while delivering genuine benefits.
3. Nature-Inspired Actives: Gentle Power from Plants
The trend towards plant-based alternatives and away from synthetic actives is growing rapidly. As a formulator, this is your sweet spot: creating effective products using gentle, natural ingredients.
Understanding the shift: Many popular skincare actives are isolated compounds found naturally in plants. Instead of using harsh synthetic versions, you can harness the whole plant's wisdom.
Smart substitutions for DIY and Business formulators:
Instead of Retinol: Use Rosehip oil or Buckthorn oil
Instead of Salicylic Acid: Try Willow bark extract
Instead of Glycolic Acid: Explore fruit enzymes from papaya or pineapple
Instead of Hyaluronic Acid: Use Tremella mushroom extract, aloe vera gel or glycerine
The herbal advantage: Whole plant extracts are typically gentler than isolated compounds because they contain natural buffering compounds that work synergistically with the active ingredients.
4. K-Beauty and Cultural Influences: A Global Skincare Revolution
Korean beauty, or K-Beauty, has transformed the global skincare landscape, introducing innovative ingredients and multi-step routines that prioritise skin health over quick fixes. As a DIY formulator, you can draw inspiration from these cultural approaches to create products that reflect this holistic philosophy.
What makes K-Beauty special: The focus isn't just on treating problems. It's about preventing them. K-Beauty emphasises gentle, consistent care with products that work together harmoniously. This approach perfectly aligns with DIY formulation principles.
K-Beauty inspired ingredients to explore:
Ginseng
Green Tea
Rice Water
Snail Secretion Filtrate (challenging for DIY)
Fermented Ingredients
Cultural beauty wisdom from around the world:
Japanese: Sake, seaweed
French Pharmacy: Thermal spring water
Ayurvedic: Turmeric, neem, herb-oil combos
Mediterranean: Olive oil, honey, sea salt
Adapting cultural trends: Understand the philosophy behind the trends. K-Beauty teaches that skincare should be a mindful ritual. Develop signature blends combining cultural wisdom and local ingredients.
Getting started: Start with rice water or green tea fermentations. Gradually explore more complex cultural formulations as your skills grow.
5. AI as a Trendy Tool: Your Digital Co-Founder
AI is rapidly becoming one of the hottest trends in skincare. From customising products based on skin types to helping with ingredient research, AI is changing the game. Big brands are investing in AI - and so can you.
How you can use AI: Tools like ChatGPT can serve as your brainstorming partner, marketing assistant, or ingredient researcher. Use it for dermal limits, formulation checks, or marketing ideas.
⚠️ Important note: Always verify AI-generated ideas. Perform thorough testing for safety and effectiveness before including AI-assisted recommendations in your products or advice.

Wrap-up
What Are Essential Oil Notes?
Essential oil notes refer to the classification of oils based on their volatility—how quickly they evaporate and how long their aroma lasts. This concept comes from traditional perfumery, where fragrances are carefully layered to create complex, evolving scents that develop over time.
Essential oils are categorised into three main notes:
Top Notes (Head Notes): Light, fresh, uplifting aromas that evaporate quickly—typically within 30 minutes to 2 hours.
Middle Notes (Heart Notes): Warm, soft, balancing aromas that form the body of your blend—lasting 2 to 4 hours.
Base Notes: Deep, rich, grounding aromas that evaporate slowly—lingering for 4 to 8 hours or even days.
Think of essential oil notes like musical notes in a symphony. Top notes provide the bright, initial impression; middle notes carry the melody; and base notes offer depth and foundation. Together, they create a harmonious, well-rounded fragrance experience.
Why Volatility Matters
The concept of notes is directly tied to molecular weight and volatility. Essential oils contain dozens or even hundreds of individual chemical compounds, each with different evaporation rates.
Light molecules (like those in citrus oils) evaporate quickly, giving us top notes. Heavy molecules (like those in wood and resin oils) evaporate slowly, creating base notes. Middle notes contain medium-weight molecules that bridge the two.
Understanding this chemistry helps you predict how your blends will behave over time and how to compensate for rapid evaporation.
Why Notes Matter in Skincare and Soapmaking
Fragrance Longevity
One of the most common complaints about natural products is that the scent fades too quickly. This happens because many formulators rely heavily on top-note essential oils, particularly citrus without balancing them with middle and base notes.
When you understand notes, you can anchor your fast-evaporating oils with slower-evaporating base notes, extending the life of your fragrance from hours to days. This creates a more satisfying sensory experience for your customers.
Scent Evolution
A well-balanced blend doesn't smell the same from first application to final dry-down. It evolves, revealing different aromatic layers as the hours pass.
Initial application highlights the bright top notes perhaps fresh bergamot and lemon. After 30 minutes, the top notes fade and middle notes emerge maybe soft lavender and geranium. Several hours later, the base notes dominate warm sandalwood and patchouli. This aromatic journey creates depth and interest, making your products memorable.
Product Type Considerations
Different product formats interact with essential oil notes in unique ways:
Soap: The saponification process and high pH can alter or diminish certain essential oils. Citrus top notes often fade during cure time or within weeks of use. Using more base notes ensures your soap retains scent throughout its life.
Leave-on skincare (creams, lotions, body oils): All three notes can shine because the product remains on skin for hours. Balancing notes creates a pleasant, evolving experience.
Rinse-off products (cleansers, shampoos): Top and middle notes have more impact because the product is washed away quickly. Heavy base notes may be less noticeable.
Cost Efficiency
Base-note essential oils tend to be more expensive than top notes. However, because they're more concentrated and longer-lasting, you often need less of them. Understanding notes helps you create cost-effective blends that deliver maximum aromatic impact.
Therapeutic Balance
Beyond fragrance, notes also relate to aromatherapeutic properties. Top notes are often energising and uplifting; middle notes are balancing and harmonising; base notes are grounding and calming. Blending across all three notes creates products that support both physical and emotional wellbeing.
The Three Notes Explained
Top Notes (Head Notes)
Characteristics:
Light, fresh, bright, sharp, or citrusy aromas
Evaporate within 30 minutes to 2 hours
Create the first impression
Often energising, uplifting, or clarifying
Lower molecular weight
Common Top-Note Essential Oils:
Citrus family: Lemon, lime, bergamot, grapefruit, sweet orange, mandarin, tangerine
Mints: Peppermint, spearmint
Herbs: Basil, eucalyptus, tea tree
Others: Lemongrass, lemon myrtle, citronella
Usage Tips:
Use top notes at 20–40% of your blend for balanced formulations
Increase to 50–60% if you want a bright, fresh-dominant scent
In soap, consider using top notes at lower percentages as they fade fastest
Pair with base notes to extend longevity
Top-Note Challenge in Soap:Citrus oils are notoriously difficult to retain in cold-process soap. The alkaline environment and curing process can strip away these delicate aromas within weeks. Using litsea cubeba (may chang) or lemongrass alongside expressed citrus oils helps anchor the scent. Always increase citrus oil percentages slightly to compensate for loss.
Middle Notes (Heart Notes)
Characteristics:
Soft, warm, floral, herbaceous, or spicy aromas
Evaporate within 2 to 4 hours
Form the main body and character of your blend
Often balancing, harmonising, or soothing
Medium molecular weight
Common Middle-Note Essential Oils:
Florals: Lavender, geranium, chamomile, ylang-ylang, neroli
Spices: Black pepper, cardamom, coriander, ginger
Herbs: Clary sage, rosemary, marjoram, fennel
Others: Pine, cypress, juniper berry, tea tree (overlaps with top)
Usage Tips:
Use middle notes at 30–50% of your blend as the foundation
They act as bridges between volatile top notes and heavy base notes
Excellent for creating well-rounded, balanced blends
Most middle notes hold up well in both soap and skincare
Why Middle Notes Matter:Middle notes are the "heart" of your fragrance. They emerge once top notes fade and work harmoniously with base notes to create a smooth transition. Without middle notes, your blend can feel disjointed—jumping abruptly from bright citrus to heavy wood.
Base Notes
Characteristics:
Deep, rich, earthy, woody, or resinous aromas
Evaporate slowly, lasting 4 to 8 hours or longer
Provide depth, grounding, and staying power
Often calming, centering, or sensual
High molecular weight
Common Base-Note Essential Oils:
Woods: Sandalwood, cedarwood, rosewood
Resins: Frankincense, myrrh, benzoin
Roots: Vetiver, ginger (can overlap with middle)
Others: Patchouli, ylang-ylang (overlaps with middle), vanilla absolute
Usage Tips:
Use base notes at 10–25% of your blend
A little goes a long way, base notes are potent
Essential for soap to maintain scent through cure and use
Act as fixatives, slowing the evaporation of lighter notes
Base Notes as Fixatives:Base notes don't just add their own aroma, they also slow down the evaporation of top and middle notes. This "fixative effect" extends the entire blend's longevity. Patchouli, vetiver, and sandalwood are particularly effective fixatives.
Note Classification Can Overlap
Some essential oils straddle categories, exhibiting characteristics of two notes:
Ylang-ylang: Middle to base (sweet floral with lasting depth)
Clary sage: Top to middle (bright opening, herbaceous body)
Tea tree: Top to middle (fresh camphoraceous opening, medicinal body)
Ginger: Middle to base (spicy warmth with earthy depth)
These "bridge oils" are valuable for creating smooth transitions between note categories.
Classic Note Ratios for Balanced Blends
While there's no single "correct" ratio, these traditional perfumery guidelines create well-balanced blends:
Balanced Blend (Classic Pyramid)
Top notes: 30%
Middle notes: 50%
Base notes: 20%
This ratio produces a harmonious fragrance that evolves gracefully, with each note getting time to shine.
Fresh & Uplifting Blend
Top notes: 50%
Middle notes: 30%
Base notes: 20%
Great for morning skincare products, energising body washes, or citrus-forward blends.
Deep & Grounding Blend
Top notes: 20%
Middle notes: 30%
Base notes: 50%
Perfect for evening skincare, massage oils, or earthy, calming products.
Soap-Specific Ratio
Top notes: 20%
Middle notes: 40%
Base notes: 40%
Compensates for the loss of volatile top notes during saponification and cure.
How to Blend by Notes: Step-by-Step
Step 1: Choose Your Direction
Decide on the overall aromatic character you want:
Fresh and citrusy?
Floral and soft?
Earthy and grounding?
Spicy and warm?
This guides your note selection.
Step 2: Select Oils from Each Category
Choose 1–2 oils from each note category that complement your chosen direction:
Example: Fresh Garden Blend
Top: Lemon (bright, clean)
Middle: Lavender (soft, floral)
Base: Cedarwood (woody, grounding)
Step 3: Calculate Your Ratios
Decide on your note ratio based on product type and desired effect. For a balanced blend, use 30% top, 50% middle, 20% base.
If your total essential oil load is 1% of your formula (typical for facial products), and you're making 100g:
Total essential oils: 1g
Top notes (30%): 0.3g lemon
Middle notes (50%): 0.5g lavender
Base notes (20%): 0.2g cedarwood
Step 4: Create a Test Blend
Use drops in a small vial or bottle
Apply the same ratios (e.g., 3 drops lemon, 5 drops lavender, 2 drops cedarwood)
Let it sit (covered) for 24–48 hours to allow notes to marry
Step 5: Evaluate and Adjust
Smell your test blend at different intervals:
Immediately: Are the top notes too sharp or just right?
After 1 hour: Do the middle notes come through beautifully?
After 4–8 hours: Are the base notes pleasant and lasting?
Adjust ratios as needed. If top notes dominate too much, reduce them. If the blend fades too quickly, increase base notes.
Step 6: Test in Product
Essential oils behave differently in different bases. Test your blend in your actual product formulation:
In soap, scent may fade or morph during cure
In oil-based products, scent disperses differently than in water-based products
pH and other ingredients can affect aroma
Always make a small test batch before committing to full production.

Formulated to retain citrus brightness through cold-process saponification.
Special Considerations for Soapmaking
Why Soap Is Different
Cold-process soapmaking involves high temperatures (during saponification), high pH (alkaline environment), and a long cure time (4-6 weeks). All of these factors can alter or diminish essential oil aromas.
What happens to notes in soap:
Top notes: Often fade significantly or disappear entirely
Middle notes: Usually hold well but may soften
Base notes: Remain strong and stable
Soap Blending Strategies
Strategy 1: Increase Base NotesUse 40–50% base notes instead of the typical 20%. This ensures lasting fragrance throughout the bar's life.
Strategy 2: Overpour Top NotesIf you want citrus in your soap, use 30–50% more than you would in skincare. Expect some loss, but enough will remain to provide initial brightness.
Strategy 3: Use Anchoring OilsCertain essential oils act as "anchors" in soap, helping other oils stick around:
Litsea cubeba (may chang) anchors citrus oils
Patchouli and vetiver anchor floral and herbaceous oils
Clays and oat flour can also help "hold" scent
Strategy 4: Add Oils at TraceAdd your essential oil blend when your soap reaches light to medium trace (not at the beginning with other oils). This minimises exposure to heat and alkali.
Strategy 5: Test and WaitAlways test soap blends in small batches and wait through the full cure time before judging scent retention. What smells strong at unmoulding may fade, or what seems faint may strengthen.
Advanced Blending Techniques
Synergy Blending
Some essential oils enhance each other when combined, creating a scent that's more than the sum of its parts. Look for oils within the same aromatic family (e.g., citrus + citrus) or complementary families (e.g., floral + woody).
Natural pairs:
Lavender + rosemary (herbaceous harmony)
Bergamot + geranium (bright floral)
Sandalwood + rose (soft, sensual)
Peppermint + eucalyptus (cooling clarity)
Accord Building
An accord is a small blend of 2–3 oils that smell like a single note. Create accords first, then combine them into your final blend.
Example: Green Accord
Clary sage + pine + juniper berry = fresh forest scent
Use this "Green Accord" as your middle note, then add citrus top notes and cedarwood base notes.
The Rule of Three
Start simple: use just three essential oils, one from each note category. Master three-oil blends before expanding to complex five- or seven-oil formulations. Three oils can create stunning, sophisticated fragrances without overwhelming complexity.
Troubleshooting Common Problems
"My blend smells great in the bottle but disappears on skin"Solution: Increase base notes. Your blend is likely top-note heavy. Add 5–10% more base-note oils to anchor the fragrance.
"My soap loses all scent after curing"Solution: Use soap-specific ratios with higher base notes (40–50%). Consider clays to hold scent and add oils at light trace.
"All my blends smell the same"Solution: Experiment outside your comfort zone. If you always use lavender, try geranium or ylang-ylang instead. Swap cedarwood for vetiver. Small changes create big differences.
"My blend smells too heavy or cloying"Solution: Increase top notes for brightness and lift. Add 10–15% of total % of citrus or mint to lighten deep, resinous blends.
"My citrus soaps fade within a month"Solution: Replace expressed citrus oils with distilled versions where possible (they have less furanocoumarins but better staying power). Use litsea cubeba as an anchor. Increase usage rates by 30–50%.
Storage and Stability
Essential oil blends evolve over time, especially when exposed to heat, light, and oxygen. To maintain aromatic integrity:
Store blends in dark glass bottles (amber or cobalt blue)
Keep in cool, dark places (not bathroom cabinets or sunny shelves)
Fill bottles fully to minimise oxygen exposure
Label with date and replace oxidation-prone oils (citrus, tea tree, pine) after 12 months
Base-note-dominant blends improve with age as notes marry and mellow. Top-note-heavy blends should be used within 6 months for maximum freshness.
Documentation and Record-Keeping
Keep detailed records of every blend you create:
Date created
Note ratios (e.g., 30/50/20)
Exact oil percentages and weights
Product type (soap, lotion, balm)
Scent impressions at initial blending, after 24 hours, after one week
Customer feedback
This documentation helps you replicate successful blends and refine unsuccessful ones. Over time, you'll develop your signature blending style.
Understanding essential oil notes transforms your formulation work from guesswork to intentional artistry. By balancing top, middle, and base notes, you create products with lasting, evolving fragrances that delight your customers and set your brand apart.
Start with simple three-oil blends using the classic 30/50/20 ratio. Smell your blends at different intervals to understand how they develop. Adjust for product type especially soap, where base notes are your best friend.
With practice, you'll develop an intuitive sense for how notes work together, creating sophisticated, long-lasting blends that showcase the full aromatic beauty of essential oils. Whether you're crafting a bright morning face wash or a grounding evening body oil, notes are your roadmap to fragrance success.
Ready to start blending? Choose one oil from each note category, create a small test blend, and observe how it evolves over the next 8 hours. That hands-on experience will teach you more than any theory alone. Happy crafting!
