Sd Alcohol.

What it does

Functionally it is the same as cosmetic alcohol: a fast-evaporating solvent, viscosity controller, and astringent that gives products a lightweight, quick-drying feel. It is a formulation aid, not a skin treatment.

Benefits

• Solvent that dissolves ingredients which won't mix into water or oil
• Helps control viscosity and create thin, fast-absorbing formulas
• Astringent that gives a tightening, refreshing skin sensation in toners and sprays
• Quick-evaporating, leaving a clean, weightless finish

Side effects

• Drying with frequent use; can strip skin and disrupt comfort over time
• May sting or irritate sensitive, dry, or compromised skin when high in the formula
• Like other alcohols, leave-on use high on the ingredient list is the main concern for delicate skin

Who it's for

Oily or combination skin that likes a matte, fast-drying feel, and formulas needing a quick-evaporating solvent or astringent

Who should be careful
