Don’t depend on basis with SPF

So, what do you have to do? Consultants say that you must use any technique that may encourage you to reapply your sunscreen, as long as you perceive that you just in all probability gained’t be getting the total marketed SPF. Whether or not you reapply with a powder sunscreen, drown your face in an SPF setting spray or squirt sunscreen lotion onto the again of your hand and pat it on over your make-up, even a small SPF increase is best than nothing, the specialists stated.
