Alcohol
Ingredient Info
Alcohol (typically ethanol) is a volatile liquid commonly used in skincare products as a preservative, solvent, and to help products dry quickly on skin. It can penetrate the skin barrier and is often included to improve product texture and shelf stability.
Benefits
- Preservative properties that help prevent bacterial and fungal growth
- Quick-drying formula that feels lightweight
- Helps dissolve and distribute other ingredients evenly
Potential concerns
- Can strip skin of natural oils and cause dryness, especially with repeated use
- May irritate sensitive skin or compromise the skin barrier
- Can cause stinging or burning sensation on compromised or reactive skin
- May increase skin sensitivity to sun exposure
Science: Recent cosmetic science literature shows growing interest in alcohol-free formulations due to skin barrier concerns. The provided research focuses on deodorants, noting that alcohol-free alternatives are increasingly preferred in product development, though alcohol remains widely used in skincare for its preservative and solvent functions.
