What is "DENAT ALCOHOL" and what does it do?

Role: ALCOHOL

Family: DRYING ALCOHOL

Comedogenic index: 0

Denatured alcohol is a type of volatile synthetic alcohol known for its irritating effects on the skin.

2. Effects on the cutaneous barrier
Used in concentrations above 10%, denatured alcohol can weaken the skin's protective barrier by reducing or poorly reorganizing essential lipids.

3. Irritation hazard and use
If denatured alcohol is one of the first five ingredients in a product, it presents a significant risk of skin irritation. This type of alcohol also includes ethyl alcohol, SD alcohol and denat alcohol.

4. Ingredient penetration and associated risks
Although it can enhance the penetration of other ingredients into the skin, its action can cause skin irritation and trigger cell death (apoptosis). Formulas containing both denatured alcohol and other irritants, such as menthol or fragrance oils, are particularly harmful to the skin.

Conclusion
The use of denatured alcohol in cosmetics should be assessed with caution, given its potential effects on skin irritation and degradation of the skin barrier.

In my opinion, regular and prolonged exposure to alcohol can damage the skin barrier and cause inflammation if you have dry skin.
This controversial ingredient has many immediate benefits for the skin if you have oily skin, but also some potential drawbacks in the longer term.
