I recently heard that SPF is bad for your skin. Is it true, and is it cause for concern?

Skin

Not at all, it is a big myth, A broad spectrum sunscreen with SPF 30 and PA +++ is a must for everybody, especially those who spend a lot of their time outdoors. In order to prevent sun tan, skin pigmentation, rashes, fine lines, and wrinkles, it is highly advisable to use SPF everyday.
