Glycolic Acid, a brightening solution, is the most common alpha hydroxy acid (AHA). It stimulates new growth of skin, collagen and elastin. As well as working to diminish brown spots and hyperpigmentation, it also reduces fine lines, wrinkles, acne, scars and other signs of ageing. Glycolic Acid Brightening Solution prevents dead cells from clumping together, thus increasing cell turnover. The skin appears bright and rejuvenated, reflecting a healthy glow.
