I'd like to use this product to correct my pigment problem on face. Should it be used as a treatment for no more than certain period? Say 6 months?
As my skin type is a bit dry, therefore should I use some other moisture serum or cream at the same time when I'm using the set?
If I'm intended to use Skin Medica TNS Serum to rejuvenate my collagen, should I use before or after the set?
