N-Acetyl Glucosamine and Hyperpigmentation

Scientists at P&G Beauty have identified an active ingredient  -  N-acetyl glucosamine  -  which in small-based clinical testing has been shown to reduce the appearance of hyperpigmentation gently and without irritation. And the combination of the anti-aging workhorse niacinamide and N-acetyl glucosamine significantly reduced the spot area of hyperpigmentation as assessed by quantitative image analysis better than niacinamide alone.
