Every active in the AULA line, what it does, and which formula carries it — the hero of each formula, all eleven forms of hyaluronic acid, the full peptide complex, and the supporting cast across the cream, serums and mist. No proprietary blends, no mystery actives. If it's doing the work, it's on this page.
Hero actives
The
heroes.
The single active each formula is built around. Listed by name and job — no proprietary blends, no mystery actives.
Hydration
Hyaluronic Acid
An eleven-form system spanning 3,000 to 2.3 million Daltons — the broadest in skincare. Surface forms plump and film; deep forms hydrate from below and signal your skin to make more of its own. See the full breakdown below.
- In: HA Hydrate
Clarity
Niacinamide
Vitamin B3 paired with Zinc PCA. Regulates sebum, visibly reduces pore size over 4–8 weeks, fades post-blemish marks, and strengthens the barrier rather than disrupting it.
- In: Niacinamide Clear
Brightening
Vitamin C
3-O-Ethyl Ascorbic Acid — a more stable, gentler and more effective form of vitamin C than L-ascorbic. Neutralises free radicals from UV and pollution and is a required cofactor for collagen production. Best in the AM.
- In: Vitamin C Bright
Firming
Peptide Complex
A three-peptide system — Matrixyl, copper peptide, and Argireline — that signals fibroblasts to build collagen and elastin, delivers copper for cross-linking, and relaxes expression lines. See the full breakdown below.
- In: Peptide Firm
Recovery
Exosome Technology
Extracellular vesicles that carry growth factors and signaling molecules directly into skin cells, accelerating cellular recovery and cumulatively improving texture. Most effective when skin is in repair mode.
- In: Exosome Restore
Soothing
Provitamin B5
Panthenol. Pulls water into the skin and soothes irritation, making it the gentlest way to rebuild a compromised barrier.
- In: B5 Calm
Barrier
Barrier Lipids
Ceramides and fatty acids in a PEG-free, olive-derived emulsifier base that forms a protective occlusive layer, locks in serums, and prevents transepidermal water loss. The close of every stack.
- In: Barrier Repair Cream
Refresh
Centella Asiatica
Cica. Works with Calendula to calm redness while Betaine and glycerin deliver immediate surface hydration — the active heart of the midday mist.
- In: Hydra Boost Essence
Cleanse
Gentle Surfactants
Betaine and Decyl Glucoside create a soft foam that lifts makeup and impurities, while Sodium Hyaluronate and Panthenol leave skin clean but never stripped.
- In: Cloud Cleanser
The HA system
Eleven
forms.
Most HA serums use one molecular weight. HA Hydrate uses eleven, spanning 3,000 to 2.3 million Daltons. The largest sit on the surface and form a smoothing film; the smallest reach the layer where your skin makes its own HA and signal it to make more. Together they hydrate at every depth at once.
~2.3M Daltons
High-MW Sodium Hyaluronate
The largest form. Sits on the surface and forms a breathable, smoothing film that locks moisture in for an instant plump.
~1.8M Daltons
Sodium Hyaluronate Crosspolymer
A cross-linked network that holds many times its weight in water at the surface for long-lasting, cushiony hydration.
~1.2M Daltons
Hyaluronic Acid
Classic high-weight HA. Builds the smoothing, plumping film just below the surface layer.
~1M Daltons
Sodium Hyaluronate (HMW)
Bridges the surface film and the upper layers, keeping hydration continuous through the day.
~800k Daltons
Sodium Hyaluronate (MMW)
A mid-weight form that binds moisture into the upper epidermis so skin stays hydrated past the first hour.
~500k Daltons
Sodium Hyaluronate (MMW)
Sinks into the upper layers to maintain a steady reservoir of water within the skin.
~300k Daltons
Hydrolyzed Sodium Hyaluronate
Partially fragmented HA that penetrates more readily, carrying hydration deeper than the high-weight forms.
~100k Daltons
Hydrolyzed Hyaluronic Acid
A low-weight fragment that reaches the mid layers, hydrating below the surface where larger forms can't go.
~50k Daltons
Sodium Acetylated Hyaluronate
Acetylated for better affinity with skin lipids, so it holds water deeper and longer than standard low-weight HA.
~10k Daltons
Mini Hyaluronic Acid
A very small fragment that reaches the deeper layers and hydrates from below for a smoother, firmer surface.
~3,000 Daltons
Oligo Hyaluronic Acid
The smallest form. Reaches the layer where skin naturally produces HA and gently signals it to keep making more.
The peptides
The peptide
complex.
Peptide Firm isn't one peptide — it's a three-peptide complex (Matrixyl, copper peptide, and Argireline) that works on three fronts: signaling collagen synthesis, delivering copper for repair, and relaxing micro-contractions. Peptides are a long game; use them toward the end of your serum routine.
Matrixyl
Palmitoyl Pentapeptide-4
The signal peptide behind Matrixyl. It communicates with fibroblasts to stimulate collagen and elastin production, rebuilding firmness over time.
- In: Peptide Firm
Argireline
Acetyl Hexapeptide-8
Relaxes the repeated micro-contractions that deepen expression lines over time — a topical approach to softening dynamic wrinkles.
- In: Peptide Firm
GHK-Cu
Copper Peptide
Copper Tripeptide-1. Delivers copper to support enzyme activity for collagen cross-linking and skin repair — one of the most studied regenerative peptides.
- In: Peptide Firm
Supporting cast
The
supporting actives.
The humectants, soothers and antioxidants that appear across the cream, serums and mist to make every hero work better.
Clarity
Licorice Root Extract
Glycyrrhiza Glabra root extract. Calms redness and helps fade uneven tone — a quiet brightening workhorse across the clarifying and recovery formulas.
- In: Niacinamide Clear, Exosome Restore
Antioxidant
Yuzu Peel Extract
Citrus Junos peel extract. A vitamin-C-rich botanical antioxidant that supports the brightening complex and helps defend against UV and pollution damage.
- In: Vitamin C Bright
Soothing
Chamomile Extract
Matricaria Recutita flower extract. Calms reactive, irritated skin and supports the barrier — the soothing heart of the gentlest hydrating formula.
- In: B5 Calm
Hydration
Glycerin
The most reliable humectant in skincare. Draws and holds water in the upper layers across every formula in the line.
- In: Every formula
Hydration
Betaine
An osmolyte-style humectant that delivers immediate surface hydration and softens the foam in the cleanser.
- In: Hydra Boost Essence, Cloud Cleanser
Calming
Calendula
A botanical that works with Centella to calm visible redness and soothe reactive skin throughout the day.
- In: Hydra Boost Essence
Hydration
Saccharide Isomerate
A plant-derived sugar complex that binds to skin like a second layer of hydration, holding water where the barrier needs it most.
- In: Barrier Repair Cream
Mineral
Zinc PCA
Paired with niacinamide to regulate sebaceous activity and support clearer, less congested skin.
- In: Niacinamide Clear
Cleanse
Decyl Glucoside
A mild, sugar-derived surfactant that lifts makeup and impurities into a soft foam without stripping the barrier.
- In: Cloud Cleanser
