N-acetyl glucosamine (NAG) is considered to be a “skin identical ingredient”, meaning it’s found in our skin in the spaces between the cells, and it is used to maintain skin’s barrier abilities and reduce dryness.
Despite it’s unfortunate acronym NAG is not a drag.
NAG can support collagen and hyaluronic acid production, increase moisture content of the skin, increase elasticity of the skin and increase exfoliation of the skin similar to alpha hydroxy acids but without the irritation which all contribute towards improvements in skin tone and texture.
Not a pigment of your imagination . . .
For many women and men hyperpigmentation is a very real issue.
NAG has been shown to reduce hyper pigmentation and can be combined with niacinamide to further increase its ability to reduce hyper pigmentation.
High concentrations of NAG – as high as 10% – have not shown noticeable irritation of the skin.
