Formulators use it to dissolve oils and fragrance and to speed up drying. That quick drying leaves a light, cool feel, which is why it appears in deodorants, perfumes and scalp treatments. It can also help other ingredients blend into one smooth liquid.

Frequently asked questions

Is alcohol in skincare the same as drinking alcohol?

They are related, since both are forms of ethanol. Skincare alcohol is often denatured, so it has added agents that make it unfit to drink. It works as a solvent and a fast-drying carrier.

Does alcohol dry out skin?

It can. Simple alcohols evaporate quickly and can pull oils off the surface, which may feel tight or stinging on dry or sensitive skin. Many people with normal or oily skin find it fine.
