Ingredients explained

Water

Primary solvent and base; requires preservative system to prevent microbial growth

Isopropyl Myristate

Light synthetic ester, fast-drying and non-greasy; high comedogenic risk, limit in acne-prone skin

Isododecane

Synthetic hydrocarbon solvent providing dry, silky skin feel; high volatility, non-comedogenic, common in sunscreens and foundations, usage 5-30%.

Isononyl Isononanoate

Light, low-viscosity ester emollient; excellent spreadability, good for gels and light lotions

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

Tranexamic Acid

Tranexamic acid for skin brightening; generally mild at low external doses.

Lactobionic Acid

Polyhydroxy acid for pH buffering; gentle, check stability at high levels

Hydroxyethylpiperazine Ethane Sulfonic Acid

Non-ionic buffer to adjust pH around 5.5; commonly used at 0.1–0.5%

Hydrogenated Olive Oil Unsaponifiables

Oleic unsaponifiables (squalane/phytane); heavy-duty emollients suitable for dry, damaged skin repair

1,2-Hexanediol

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

Hydroxyacetophenone

Hydroxyacetophenone as antioxidant; often boosts Vitamin C, works in acidic pH.

Acetyl Glucosamine

Glycosaminoglycan precursor supporting skin hydration and elasticity; highly biocompatible.

Zinc Pca

Zinc salt for sebum control and antimicrobial; often paired with PCA sodium, high levels may cause sensitization

Phytosteryl Oleate

Phytosterol oleate, barrier repair & emollient, 1-3%; lipophilic, oxidizes, needs antioxidants.

Tocopherol

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

Calophyllum Inophyllum Seed Oil

Tamanu oil rich in omega-3s; potential antioxidant benefits; highly comedogenic, use with caution on acne-prone skin.

Sodium Chloride

Salt for gel viscosity control; used as precipitant in soaps

Octyldodecyl Myristate

Lightweight ester for smooth, non-greasy feel; acts as an emollient.

Disodium EDTA

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

Sodium Hyaluronate

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

Capparis Spinosa Fruit Extract

Capers fruit extract; rich in polyphenols, antioxidant and soothing, control batch-to-batch variability

Centella Asiatica Extract

Centella asiatica extract for soothing/repair; low irritation, common in sensitive skin products.
