Formula IngredientSolventINCI: Alcohol
Alcohol (INCI: Alcohol, also known as ethanol) is a simple, volatile alcohol used in cosmetics primarily as a solvent, antimicrobial agent, astringent, and viscosity controller. It creates cosmetically elegant, fast-absorbing, thin formulas by dissolving ingredients that are insoluble in water or oil. It is a controversial ingredient: while it provides immediate sensory and preservative benefits, it can be drying and potentially barrier-disrupting when present at high concentrations.

Alcohol can cause irritation, stinging, and barrier disruption when present at high concentrations (listed in the first 5-7 ingredients). At lower concentrations it is generally well tolerated. Sensitive, eczema-prone, and rosacea-prone skin types are most at risk. No EU CosIng Annex II or III restrictions apply for cosmetic use.
Alcohol does not directly increase photosensitivity. However, barrier disruption from high-concentration alcohol products could theoretically reduce the skin's resilience to UV damage.
Topical ethanol in cosmetic formulations is considered safe during pregnancy. Systemic absorption from topical cosmetic application is minimal and not a concern at normal use levels. The concern with alcohol relates to ingestion, not topical cosmetic use.

Individuals with sensitive skin, rosacea, eczema, dry skin, dehydrated skin, compromised skin barrier should review the considerations above before use.
