Ingredients explained

Aqua

Solvent, main base; microbial control is critical

Niacinamide

Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity

Glycerin

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

Buddleja Globosa Leaf Extract

Not decoded yet

Panthenol

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

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

Sodium Hyaluronate

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

Hydrolyzed Hyaluronic Acid

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

Hyaluronic Acid

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

Sodium Hyaluronate Crosspolymer

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

Hydrolyzed Glycosaminoglycans

Hydrolyzed GAGs for hydration/conditioning; low MW, good penetration, low irritancy.

Equisetum Arvense Leaf Extract

Not decoded yet

Daucus Carota Sativa Root Extract

Carrot root extract with carotenoids; skin conditioning, low photosensitivity, may stain.

Aesculus Hippocastanum Seed Extract

Horse chestnut seed extract for skin care; soothing, used in circulation products

Hypericum Perforatum Extract

St John's Wort extract with soothing/antimicrobial/antioxidant benefits; **high photosensitivity**, strict sun protection required after application.

Panax Ginseng Root Extract

Botanical extract for skin and hair conditioning; activity and irritation risk vary by source/purity, patch test for sensitive skin

Echinacea Angustifolia Root Extract

Echinacea root extract for skin/hair/nail care; watch for Asteraceae pollen allergies

Butylene Glycol

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

Allantoin

Skin soother at 0.5-2%; promotes cell regeneration

Hydroxyethylcellulose

Water-soluble cellulose ether for thickening and suspension stabilization; sensitive to ions, electrolytes reduce viscosity, use at pH 7-8.

Maltodextrine

Not decoded yet

Propanediol

Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative

Tetrasodium EDTA

Chelator removing metal ions to enhance antioxidant and preservative efficacy; very low usage, typically 0.05-0.1%, no direct skincare function.

Carbomer

Gelling thickener requiring neutralization; watch out for ion compatibility

Polysorbate 20

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

Benzyl Alcohol

Mild preservative/solvent at 0.5-1.0%; EU allergen (labeling required), irritation risk if concentrated, avoid in infant/highly sensitive skin.

Sodium Benzoate

Preservative booster, effective below pH 4.5; combinable with sorbates

Potassium Sorbate

Preservative effective below pH 6; combinable with sodium benzoate

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
