Alcohol (Ethanol)

Alcohol (Ethanol) is a simple alcohol. Alcohol in skincare is used as a solvent, preservative, and antiseptic. It also helps active ingredients absorb better into the skin.

How to use it

Alcohol isn't used as an active ingredient—it's added to support the formula.

Suitable for

It depends on the concentration and type of product. Not suitable for dry, atopic, or sensitive skin, or for children.

Things to know

Alcohol in skincare is one of the most controversial ingredients. Contrary to popular belief, it isn't universally bad. It all depends on the type of alcohol, its concentration, and, most importantly, your skin type.

The main risk of ethanol is its ability to disrupt the skin barrier, leading to dehydration and irritation. This is more likely to happen when:

• The concentration is high.
• Alcohol (ethanol) appears in the first five ingredients—a sign of high concentration.
• Your skin type puts you at risk. Dry, sensitive, and damaged skin (for example, with eczema) faces the greatest risk, since ethanol can cause severe irritation and further disrupt the barrier.

FAQ

1. Can I use products with alcohol every day?

Generally, no. Products with a high concentration of simple alcohols shouldn't be used every day. Alcohol in skincare can dry out the skin and damage its natural protective barrier.

2. How can I minimize dryness when using products with alcohol?

To minimize dryness, apply a moisturizer right after using the product with alcohol. This helps lock in moisture before it evaporates.

3. Why is ethanol commonly used in products for oily skin?

Ethanol is popular in skincare for oily and acne-prone skin due to several properties: it controls sebum, fights bacteria, and helps other ingredients absorb better. That said, no skin type should use simple alcohols regularly, as they can cause dryness and dehydration.
