Ingredients explained

Hydrolyzed Collagen

Hydrolyzed protein for film-forming and moisture; molecular weight limits penetration, check source for shellfish allergies

Butylene Glycol

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

Glycerin

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

PEG-8

Not decoded yet

Cetyl Ethylhexanoate

Synthetic oil providing slip; large molecule, low penetration, non-comedogenic, suitable for dry or rough skin.

Dimethicone

Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin

Cetearyl Alcohol

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

PEG-40 Stearate

Water-soluble emulsifier for O/W; mild cleansing, high levels may be comedogenic, caution for sensitive skin.

Sorbitan Sesquioleate

Non-ionic emulsifier for O/W or W/O systems; moderate emulsification power, often used with co-emulsifiers

Stearic Acid

Fatty acid emulsifier, white waxy solid; adds slip feel

Hydrogenated Vegetable Oil

Occlusive emollient for smooth feel; high levels may be comedogenic, use caution for acne-prone skin

Beeswax

Beeswax, natural thickener and film former; provides occlusive moisturization, natural honey scent, animal-derived, potential allergen

Argania Spinosa Kernel Oil

Jojoba oil rich in unsaturated fats; good penetration, non-comedogenic, prone to oxidation requiring antioxidants

Sodium Hyaluronate

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

Phenoxyethanol

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

1,2-Hexanediol

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

Caprylyl Glycol

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

Pentylene Glycol

Polyol humectant at 1-3%; low irritancy, suitable for sensitive skin

Butyrospermum Parkii

African oil/fat/wax; clarify form (oil, butter, or powder) as function depends on it.

Theobroma Cacao Seed Butter

Heavy, occlusive plant butter; medium comedogenic rating, avoid on oily skin.

Carbomer

Gelling thickener requiring neutralization; watch out for ion compatibility

Milk Protein Extract

Protein-based humectant/conditioner <5%; allergenic for lactose-sensitive, hygroscopic so needs preservative

Aloe Barbadensis Leaf Extract

Aloe vera leaf extract for soothing and humectant; monitor polysaccharide level and endotoxins

Euterpe Oleracea Fruit Extract

Açaí extract; rich in antioxidants; used for hair/skin, oil-based so needs emulsification.

Urea

Potent humectant and keratolytic, >10% has exfoliating effect; stinging sensation at high levels, sensitive skin caution

Star anise extract with anethole; fragrant and conditioning, allergen present, high levels risk sensitivity.

Potassium Hydroxide

Strong alkali pH adjuster, trace usage (<0.1%); corrosive, must be neutralized.

Fragrance

Fragrance; concentration must control allergen risk, label specific components

Adenosine

Skin conditioner at 0.1-1%; used for anti-aging and repair

Disodium EDTA

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

Sesamum Indicum Seed Extract

Sesame seed extract rich in oils and sesamin; used for hair and skin conditioning with smoothing and soothing properties.

Allantoin

Skin soother at 0.5-2%; promotes cell regeneration

Magnesium Ascorbyl Phosphate

Water-soluble Vitamin C derivative for antioxidant and brightening; more stable than ascorbic acid

Lactic Acid

AHA pH adjuster at 0.5-5%; exfoliation/humectancy, mild at low conc., irritating at high, avoid conflict with alkaline preservatives.

Citric Acid

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

Malic Acid

AHA for pH buffering; mild at low conc, risk at high, control pH & total acidity

Ceramide 3

Ceramide 3 to restore skin barrier and moisturize; used at 0.01–1%, often blended
