In summer, you have taken the excellent habit of protecting your face from the harmful effects of UV rays with sunscreen. But what about your hands when you are on a terrace, in a garden or while sunbathing on vacation? However, they are as exposed like the face and subject, just like it, to the appearance of spots. Because UV rays are responsible for the formation of early wrinkles and a loss of firmness of the skin, they are also at the origin of the production of melanin (the substance responsible for tanning) and cause the long term stain. So get into the good habit of protecting your hands with a very high protection treatment (SPF 30 or 50) to prevent the formation of unsightly stains.
