iS Clinical Brightening Serum 15ml is a powerful nighttime formula that gently exfoliates while safely reducing the appearance of uneven skin tone. Suitable for hyperpigmentation and uneven skin tone. Key ingredients include Bilberry, a natural AHA exfoliant with moisturising properties. 1% White Willow Bark (source of Salicylic Acid) exfoliates the skin and deeply cleans pores. 2% Sugarcane (source of Glycolic Acid) gently exfoliates the skin for a renewed complexion. Norwegian Kelp and 2% Mushroom extract assist in brightening the overall complexion. 1% Alpha Arbutin inhibits tyrosinase production, controlling hyperpigmentation. Fragrance-free. Dr Webster’s Recommendation: iS Clinical Brightening Serum concentrate contains powerful brightening ingredients that can be used over the whole face or even as a targeted spot treatment. This serum works as a booster, providing controlled exfoliation (without peeling) to help address uneven skin tone on multiple levels. This active product may produce a slight tingling sensation.
