More info about Alcohol-Based Products
Alcohol-Based Products: Research makes it clear that alcohol, as a main ingredient in any product, especially one you use frequently and repeatedly, is a problem.
When we express concern about the presence of alcohol in makeup products, we’re referring to denatured ethanol, which most often is listed as SD alcohol, alcohol denat., denatured alcohol, or (less often) isopropyl alcohol.
When you see these types of alcohol listed among the first six ingredients on an ingredient label, without question the product will irritate and cause other problems for skin. There’s no way around it—these volatile alcohols are simply bad for all skin types.
The reason they’re included in products is because they provide a quick-drying finish, immediately degrease skin, and feel weightless, so it’s easy to see their appeal, especially for those with oily skin. If only those short-term benefits didn’t lead to negative long-term outcomes!
Using products that contain these alcohols will cause dryness, erosion of skin’s protective barrier, and a strain on how skin replenishes, renews, and rejuvenates itself. Alcohol just weakens everything about skin.
The irony of using alcohol-based products to control oily skin is that the damage from the alcohol can actually lead to an increase in breakouts and enlarged pores. As we said, the alcohol does have an immediate de-greasing effect on skin, but it causes irritation, which eventually will counteract the de-greasing effect and make your oily skin look even more shiny.
There are people who challenge us on the information we’ve presented about alcohol’s effects. They often base their argument on a study in the British Journal of Dermatology (July 2007, pages 74–81) that concluded “alcohol-based hand rubs cause less irritation than hand washing….” But, the only thing this study showed was that alcohol was not as irritating as an even more irritating hand wash, which contained sodium lauryl sulfate. So, the study is actually just telling you that one irritant, sodium lauryl sulfate, is worse than another irritant, alcohol.
Not all alcohols are bad. For example, there are fatty alcohols, which are absolutely non-irritating and can be beneficial for skin. Examples that you’ll see on ingredient labels include cetyl alcohol, stearyl alcohol, and cetearyl alcohol, all of which are good ingredients for skin. It’s important to differentiate between these skin-friendly alcohols and the problematic alcohols.
