Niacinamide
Even though Niacinamide is not the key ingredient in the L'Oréal Paris Glycolic acid face wash, it plays a major role in treating hyperpigmentation and skin brightening. Niacinamide, also known as vitamin B3 is popular for its anti-inflammatory properties. It hydrates your skin, minimizes fine lines and wrinkles, treats hyperpigmentation, and treats acne at the same time. It is ideal for all skin types, especially sensitive skin as it reduces redness and itchiness.
