Exfoliation is key! Skin is constantly shedding dead skin cells, and by exfoliating you help turnover skin cells faster. Our 10% Glycolic + Lactic Acid is the highest percentage that can be left on skin, and it’s still gentle enough to be used daily. The combination of both AHA’s helps exfoliate, brighten, reduce dark spots, stimulate collagen production leaving your skin soft and supple and renewed. It’s time to exfoliate! Lactic Acid – Helps not only skin cell turnover for smoother skin, it also helps reduce dark spots. It is also considered a humectant, which means it helps draw in moisture to your skin. Glycolic Acid - Slightly stronger of the AHA’s but still can be used daily if at a small percent. Not only does it help with exfoliation but it also helps stimulate the production of Collagen. Some Cautions: ALWAYS use an SPF on the area you just used AHA’s on. Skin does become more sensitive while using AHA’s or any acids. Your skin is more prone to getting sunburned, so we ALWAYS recommend using an SPF following using this product. Sensitive Skin: Even though this is gentle enough to use every day, some skin is more sensitive than others, and we recommended that you start twice a week gradually building up to everyday. If redness or irritation occurs, we suggest to stop using the product, or to ease up on how often it is used. No Added Fragrances: With such a potent level of AHA’s in the formula, we stay away from using fragrance to help minimize the chances of irritation. Dermatology & Allergy tested.
