I'm really worried .. My daughter is having these spots on her face which have occurred after her acne problem. The pigmentation is all gone but the scars are there for so long and i haven't found any reliable product which could make her scars disappear . Please help . I've heard of this product InviCible Scars Advanced Scar Treatment | For Scars & Dark Spots Is it worth buying ? I have also heard about Mederma Skin Care for Scars, Scarring & Stretch Marks | Mederma.com. Please tell me what are your views regarding both these products ?
