American Academy of dermatology categorically states that there is no oral sunscreen which is effective and protective against Sun light. other than Topical sunscreens. Is there any significant difference between the cosmetic sunscreens of Lakme, Lotus etc against the versus the prescribed ones. How different are the cosmetic preparations and prescribed sunscreens.
Is there any method to calculate skin damage clinically after sun exposure. just as smoking years. or any score like VASI or PASI scores?
