The ProX by Olay Dermatological Anti-Aging Even Tone Spot Fading Treatment that offers something a little bit different from your traditional dark spot treatment. Most dark spot treatments contain either vitamin C or salicylic acid to exfoliate and brighten the skin. The Olay ProX however, uses niacinamide instead of these ingredients in order to deliver the majority of the brightening results. Depending on your skin type, this could actually be a better alternative. Niacinamide, or vitamin B5, is a much gentler ingredient than vitamin C or salicylic acid. Vitamin C, depending on your skin type, can take a few weeks for your skin to get used to. Salicylic acid, on the other hand, doesn’t require an adjustment period, but can be irritating if used every single day, as many dark spot treatments suggest. So if you have sensitive skin, the Olay ProX Even Skin Tone Spot Fading Treatment may be a better alternative for you. Additionally, niacinamide has also been known to help pores appear smaller, so if you’re concerned about enlarged pores, this may be an added bonus for you.
