Formulation view Aqueous base with Chondrus crispus extract for thickening. Features a dense stack of eight signal peptides (collagen-inducing, firming) and panthenol for multi-pathway regulation. Combined with sodium hyaluronate crosspolymer and multiple hyaluronic acid forms for long-lasting hydration. Preserved with phenoxyethanol and ethylhexylglycerin. Formulator note: High peptide loading poses stability challenges; suitable for mature or damaged skin focusing on anti-aging and repair.

Ingredients explained

Aqua

Solvent, main base; microbial control is critical

Chondrus Crispus Extract

Carrageenan for thickening and moisturizing; seaweed-based, pH-sensitive

Palmitoyl Tripeptide-5

Peptide actives for skin conditioning; typically used at low levels.

Palmitoyl Tripeptide-38

Palmitoyl tripeptide; signaling peptide for collagen and antioxidants; 0.1-1% typical, light-sensitive

Copper Palmitoyl Heptapeptide-14

Not decoded yet

Heptapeptide-15 Palmitate

Not decoded yet

Acetyl Hexapeptide-8

Acetyl hexapeptide-8; signal peptide, low concentration, used for firming and hydration, low irritancy.

Palmitoyl Tripeptide-1

Palmitoyl Tripeptide-1 for repair; requires lipid carrier, unstable in aqueous phase

Palmitoyl Tetrapeptide-7

Palmitoyl Tetrapeptide-7 boosts collagen; use 0.1–1%, formulate with lipid carriers

Panthenol

Panthenol (vitamin B5) at 1–5%; moisturizing and reparative, supports barrier recovery

Phenoxyethanol

Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin

Ethylhexylglycerin

Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel

Polysorbate 20

Non-ionic emulsifier and cleansing surfactant; contains PEG, control microbial load.

Sodium Hyaluronate Crosspolymer

Crosslinked high-MW HA; forms surface hydrogel for long-lasting hydration, minimal penetration, physical film-forming.

Sodium Hyaluronate

Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture

Caprylyl Glycol

Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol

Hydroxypropyltrimonium Hyaluronate

Cationic hyaluronic acid, 0.1–1%; water-soluble thickener and conditioning agent.

Polyacrylate Crosspolymer-6

Water-soluble thickener; requires neutralizer, performs best at pH 5–7

Hydrolyzed Sodium Hyaluronate

Low-molecular-weight hyaluronic acid derivative with better penetration and strong hydration; different molecular weights provide hydration at various depths, typical concentration 0.1-1%.

Hyaluronic Acid

High-water-binding humectant at 0.1-1%; high-MW for surface film, low-MW for dermal potential, check cationic compatibility.

Hydrolyzed Hyaluronic Acid

Low-MW humectant with superior penetration vs high-MW; 0.1-0.5% typical, hygroscopic, store dry to prevent clumping.

Potassium Hyaluronate

Hyaluronic salt, excellent humectant; efficacy varies with MW, best with occlusive base

Sodium Acetylated Hyaluronate

Acetylated HA; modified for hydrophobicity, improved penetration and non-tacky feel compared to standard HA.

1,2-Hexanediol

Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives

Xanthan Gum

Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration

Glucose

Low-MW humectant and buffer; high hygroscopicity requires careful preservation and humidity control.

Butylene Glycol

Polyol humectant and solvent at 1–5%; aids solubilization, light feel

Polyvinyl Alcohol

Film/viscosity agent for masks/cleansers; water-soluble, forms flexible film

Phenylpropanol

Phenylpropanol for fragrance and solvent; allergen risk, requires assessment

Lactic Acid/Glycolic Acid Copolymer

AHA copolymer; exfoliating, requires buffering agents.

Glycerin

Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives

Glyceryl Caprylate

Mild emulsifier/deodorant at 0.5-2%; polyol ester, high humectancy, low irritancy, check cationic surfactant compatibility.

Citric Acid

Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH

Carbomer

Gelling thickener requiring neutralization; watch out for ion compatibility

EDTA

Chelating agent for stability; use metal salts, keep concentration low (<0.1%) to maintain pH.
