Acetylcysteine

* Also known as N-acetylcysteine or N-acetyl-L-cysteine (NAC)

Functions:

A pharmacological agent predominantly used as an expectorant to helps relieve difficulties with breathing, but it also functions as a corneal vulnerary and an antidote to acetaminophen poisoning. It consists of the amino acid cysteine, which is, in turn, responsible for boosting the body's levels of the essential tripeptide glutathione. Glutathione, a strong antioxidant, is responsible for protecting the body’s cells from toxins and free radical damage.

In cosmetics, it mainly functions as a skin conditioning agent. With regards to its potential antioxidant benefits, research seems promising. One study demonstrates how the topical applications of N-acetyl-L-cysteine helpes prevent UV induced photoaging on human skin. several other studies support these findings and suggest that the ingredient may be an effective protector against oxidantive stress. It can be found in products such as sunscreen, facial moisturizer/lotion, anti-aging treatment, mascara, eye cream, skin fader and shampoo/conditioner.
