I highly recommend this product. I had skin laser treatment and received brown spots as a result of sun exposure. Noticed immediate results after just 1 week. I was skeptical at first so I started out buying a .5 ounce bottle instead of a full ounce. That lasted me for about 5 weeks. It's non-greasy and leaves no filming on the skin. I wore it at night and during the day. Thanks, Scarguard! Love your products.
