The Kiehl’s Clearly Corrective Dark Spot Solution was designed to be a highly effective spot corrector that brightens the skin, increases radiance and boosts clarity. According to the brand, this product can help with dark spots caused by age and sun exposure, and utilizes vitamin C, white birch extract and peony extract to deliver these results. Vitamin C is one of the most popular ingredients in products that target hyperpigmentation as it helps to brighten the skin and lighten dark spots. White birch extract is an ingredient derived from sugar that helps to restore hydration and important nutrients to the skin. Finally, peony extract has been used in chinese medicine for centuries, and also acts as a potent antioxidant that protects against the oxidative damage that can actually make dark spots worse. In addition to these star ingredients, there are a few additional actives such as salicylic acid which help to exfoliate and brighten the skin. Additionally, this product does contain denatured alcohol as a primary ingredient in the base of this product, so if you have extra dry skin, this may not be the best option for you.
