Age spots form after time and are a type of hyperpigmentation on the skin. A contributing factor to the formation of age spots on the skin is the sun. Harmful sun rays penetrate the skin and damage the deeper layers, resulting in the formation of these spots. A great preventative measure is wearing an adequate sunscreen daily. To treat existing age spots, we recommend an array of skin brighteners as well as Vitamin C products. The Obagi-C System Kit is an excellent treatment for age spots. Check out that system along with many other highly-rated treatments below.
