Alcohol in skincare products

there are different types of alcohol in skincare low molecular weight alcohol like ethanol and methanol. these are added to prevent bacterial growth, make the product absorb faster also to some extent it’s poreminimizing. high molecular weight alcohols like cetyl or cetearyl alcohol have skin softening and moisture binding properties. with that said alcohol can act dryin and irritating on the skin or clogging depending on type of alcohol used

Depends on the type of alcohol, there are many. If you mean denatured alcohol, it helps with texture (the product spreads and penetrates the skin easier) and it's also a preservative. But it can dry out the skin.

I heard alcohol helps ingredients penetrate deeper into the skin. Of course it's always good to double check this information I'm sharing.

I don’t like alcohol denat and isopropyl alcohol personally in my products, because I find them drying over time for my skin(and sometimes burns, like you said in one of your comments). but the cosmetic chemist @labmuffinbeautyscience says it’s perfectly fine and helps the ingredients penetrate deeper, like others have mentioned.

I just avoid products with alcohol completely. potent alcohol makes me break out and get irritated
