I have been asked if I own stock in a sunscreen company. No, here are the top skincare concerns that suncreen protects you from:
Cancer
Ultra-Violet (UV) RADIATION causes damage on a cellular level by creating free radicals which can lead to skin cancer. Please apply sunscreen to your children's skin. Research shows that just one blistering sunburn in childhood or adolescence more than doubles a person's chances of developing melanoma later in life
Wrinkles
Depending on the research studies you read, UV is responsible for 80-90% of the damage that ages your skin. One way is by damaging the collagen and elastin fibers that keep your skin plump and firm.
Uneven Coloration
Not only does UV stimulate pigment production (not just freckles...melasma & age spots), it can damage the melanocyte (cell that produces your skin color) causing it to release more yellow, red or uneven pigment. It can even kill the cell leaving you with little spots containing no color.
Acne
Yes, the sun may have a drying effect on acne but acneic skin is fragile which increases the chance that UV exposure will leave behind scars or dark spots after the spot has cleared. Instead, use a drying ingredient such as salicylic acid.
