If you happen to’ve carried out analysis regarding skincare elements, chances are high you’ve come throughout a warning to keep away from alcohol in skincare in any respect prices.
If there’s one factor you’ll be taught from my weblog, it’s that the world of beauty chemistry isn’t black and white.

In truth, there are a lot of sorts of alcohol that may be actually useful in skincare. Preserve studying to be taught which sorts of alcohol can hurt your pores and skin and which may enhance it!
What Classifies One thing as Alcohol?
First up, what is alcohol? In beauty chemistry, an “alcohol” is any molecule with a hydroxyl group (-OH). That is merely a hydrogen and an oxygen bonded collectively. As you possibly can think about, this can be a very broad and very numerous group of chemical compounds that every one have an effect on the pores and skin otherwise.
For instance, each retinol and vitamin E are technically alcohols. Neither of those acts the way in which we count on conventional alcohol to behave, and but, they fall underneath the identical classification, chemically talking. Alcohols can perform as nearly something, together with humectants, emollients, antioxidants, emulsifiers, surfactants, and extra.
When folks discuss “dangerous” or “good” alcohol, they’re normally referring to drying or non-drying alcohol.
So what causes some types of alcohol to have a drying impact on the pores and skin? The primary issue is the dimensions of the molecule. Drying alcohols, or easy alcohols, have a extra fundamental molecular construction than non-drying alcohols. This implies they’ve a comparatively low molecular weight, which causes them to evaporate into the air rapidly. Along with this, they’re actually good at chopping by and solubilizing oil. If drying alcohols are utilized to the pores and skin too usually or in excessive concentrations, the result’s a disrupted moisture barrier, which results in dryness and irritation.
If you happen to’re trying to keep away from drying alcohols in skincare, listed here are the most typical ones:
- Isopropyl Alcohol
- Denatured Alcohol
- SD Alcohols 40 & 38
Why Are Drying Alcohols Utilized in Skincare Merchandise?
You is perhaps questioning why these elements would ever be included in a skincare product after they have the potential to be so damaging. Beauty formulations are created very deliberately, and drying alcohols do have their place. Generally they’re used to solubilize energetic elements, reminiscent of salicylic acid, to assist them get into the pores and skin. In that very same vein, alcohols can be utilized as a penetration enhancer to make a formulation simpler general. They’ll additionally assist management the feel or stability of a formulation or be utilized in a spot remedy that’s meant to be drying.
Ought to You All the time Keep away from Drying Alcohols in Skincare Merchandise?
Not essentially. It’s true that drying alcohols needs to be prevented in skincare merchandise in the event that they’re getting used at greater than a fraction of a %, and naturally, you wouldn’t need to use an alcohol-based product. (Suppose astringent toners from the ’90s. Yikes! That’s why I formulate all my toners with out drying alcohol.) That mentioned, you don’t essentially want to jot down a product off simply because drying alcohol is listed within the elements—simply be sure it’s listed towards the top. I’ve written about this earlier than, however ingredient percentages and general formulation are the whole lot when figuring out if a product will give you the results you want.
If a small quantity of drying alcohol is required for one thing like penetration enhancement, it’s normally offset with a number of different hydrating elements. For many individuals, this might be sufficient to mitigate any unfavourable results. Nevertheless, when you have delicate pores and skin or situations like rosacea or eczema, I’d counsel avoiding merchandise with drying alcohols altogether (irrespective of how low the focus could also be).
Non-drying alcohols, also known as fatty alcohols, are chemically rather more complicated than easy, drying alcohols. (You possibly can see this represented a bit within the picture above.) For the reason that molecules are larger, they’ve the next molecular weight. This implies they really sit on the pores and skin slightly than instantly evaporating and resulting in dryness.
Reality be advised, the record of non-drying alcohols is definitely very in depth because of the truth that so many elements can technically be labeled underneath the umbrella of “alcohol.” I’ll spare you, although, and follow itemizing a couple of of the most typical fatty alcohols in skincare:
- Cetyl Alcohol
- Oleyl Alcohol
- Stearyl Alcohol
- Vitamin E (Tocopherol)
- Propylene Glycol
Why Are Non-Drying Alcohols Utilized in Skincare Merchandise?
As I discussed earlier, this class is huge and covers elements that serve a variety of features. Extra particularly, although, the fatty alcohols listed above are sometimes used as hydrators or emollients. This implies they both assist the pores and skin maintain on to moisture (the alternative of their drying counterparts!), or they assist to melt and easy the pores and skin. Not solely are these alcohols non-drying, however they can be very useful to the pores and skin in some ways and there may be completely no motive to keep away from utilizing them.
Ought to You All the time Keep away from Skincare Merchandise With Alcohol?
As you possibly can see, the reply isn’t any! It’s true that drying alcohol needs to be prevented by these with delicate pores and skin, and nobody ought to use skincare merchandise with excessive concentrations of drying alcohol. That mentioned, if a tiny quantity is used for one thing like penetration enhancement, it’s normally okay for many pores and skin varieties so long as the remainder of the product formulation is thoughtfully crafted to offset attainable drying results of the alcohol.
Non-drying or fatty alcohols, nevertheless, don’t must be prevented by anybody and might be very useful to the pores and skin.
