Summary Background Striae are a common cosmetic problem, especially for women. Little has been published about chemical peel treatment of striae. Objective To recount 5 years experience of striae treated by a novel combination treatment – sand abrasion and a patent mixture containing 15% trichloracetic acid followed by 6–24 h of a patent cream under plastic occlusion. Materials and methods Sixty-nine females of various phototypes, aged 14–63 years, were treated at various anatomical sites: abdomen (43), lateral thighs (11), breasts (4), back (3), waist (3) and others (5). Striae of all types: fresh, old, mild and severe, were treated. Average follow up was 18 months. Results After 1–8 treatments (median 4.2), appearance of the striae improved by 70%. Results were best in fresher and more superficial striae. Conclusions A novel combination treatment is reported which safely, predictably and effectively improved striae in all skin types.
