How important is it to use sunblock?

Applying sunblock is necessary to achieve optimum results. Real improvement is seen only when you make a commitment to avoid and protect against sun exposure. For some patients remembering to use sunblock is not easy. However, when the skin is exposed to the suns UV rays without proper protection, the risk of hyperpigmentation reoccurring is greater. Hyperpigmentation (“age spots”), wrinkles, fine lines, pre-mature aging, these things are all caused by sun exposure. 10 minutes under the sun is the recommended daily dose for sun exposure as UV-B rays after penetrating the skin cells, promote Vitamin-D production.
