Highlights

Free of parabensFree of sulfatesFree of essential oilsFree of formaldehyde releasersContains fragranceContains mineral oilContains siliconesContains alcoholContains PEGContains animal-derivedContains EU-26 allergens

Formulation view Oil-in-water emulsion with rich esters and phytosterols for barrier support. Active payload includes retinol, a complex blend of peptides (palmitoyl tripeptide-5, etc.), and seaweed extract for long-term renewal. Simple preservation system. Ideal for mature or dry skin nightly. Factory observation: Stabilizing retinol alongside a complex peptide matrix is challenging; precise pH control is essential to balance activity and mildness, preventing irritation while maintaining efficacy.

Ingredients explained

Aqua

Solvent, main base; microbial control is critical

Caprylic/Capric Triglyceride

Light occlusive and solvent at 1–10%; non-greasy feel, suitable for oily and combination skin

Hydrogenated Polydecene

Hydrogenated polydecene, light mineral oil alternative, low comedogenic; silky, non-greasy.

Methylsilanol Mannuronate

Water-soluble silicone for anti-static and smoothness; chemically stable, no known allergenic data

Phytosteryl Canola Glycerides

Phytosterol canola glycerides, support barrier repair and moisture, stabilize lipid membrane

Ethylhexyldodecanol

Not decoded yet

Glycerin

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

Methylpropanediol

Diol solvent and extraction carrier; enhances solubility of actives, low irritation profile.

Phenoxyethanol

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

Cetearyl Alcohol

Fatty alcohol emulsifier at 1-5%; non-ionic surfactant

Glyceryl Stearate

Emulsifier at 1-3%; may require acid to prevent saponification

Peg-100 Stearate

Non-ionic emulsifier, requires ionics for stability; check PEG for formaldehyde.

Cetearyl Glucoside

Gentle non-ionic sugar-based emulsifier for low-irritation formulas; often co-blended

Glycine Soja Oil

Soybean oil emollient; prone to oxidation, needs antioxidants; suitable for dry skin

Parfum

Fragrance for scent; may contain allergens, caution for sensitive skin, full labeling required.

Sodium Hyaluronate

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

Ammonium Acryloyldimethyltaurate/Vp Copolymer

Cationic polymer providing suspension, thickening, and conditioning; often paired with anionic thickening systems, low usage, imparts slip.

Tocopherol

Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light

Ethylhexylglycerin

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

Disodium Edta

Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy

Triethanolamine

Triethanolamine for buffering; restricted, limit concentration to avoid high pH and irritation

Teprenone

Biosynthetic flavonoid for soothing/barrier; low concentrations; stability with acidic systems

Xanthan Gum

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

Carbomer

Gelling thickener requiring neutralization; watch out for ion compatibility

Retinol

Highly active and unstable, needs robust antioxidant encapsulation; 0.1-1.0%, pregnancy contraindicated

Geranylgeraylisopropanol

Not decoded yet

Hyaluronic Acid

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

Silanetriol

Basic silanetriol for hair anti-static and smoothness; must be complexed with polymers for stability

Citric Acid

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

Hydrolyzed Soy Protein

Hydrolyzed soy protein for hydration and antistatic effect; soy is a common allergen requiring labeling, low comedogenicity.

Sorbic Acid

Preservative effective at low pH, often combined with sorbate salts; check regulatory limits

Palmitoyl Dipeptide-5 Diaminobutyroyl Hydroxythreonine

Not decoded yet

Palmitoyl Tripeptide-5

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

Tetradecyl Aminobutyroylvalylaminobutyric Urea Trifluoroacetate

Complex peptide precursor for skin conditioning; limited public data, follow supplier dosage.

Magnesium Chloride

Inorganic salt for thickening and pH adjustment; 0.1-1%, avoid calcium ions

Glutamylamidoethyl Imidazole

Not decoded yet

Linalool

Natural fragrance component at ≤0.05%; one of EU 26 allergens, caution for sensitive skin

Glyceryl Caprylate

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

Hydrolyzed Yeast Protein

Hydrolyzed protein for moisture, anti-static, and barrier repair.

Sodium Benzoate

Preservative booster, effective below pH 4.5; combinable with sorbates
