Hi! neha, Welcome To HealthcareMagic forum, Neha ,LPP is a chronic problem and sadly its response to the treatment is very variable.I am sure your treating dermatologist would have told you. It appears as ash colored patches over flexures of body and chest. You can apply skinlite if you want ,but the more specific medicine is oral vit A .We usually give it for 2 weeks ,once a month and then repeat it next month too. Similarly we can 3 such cycles .In resistant cases even oral retinoids can be tried .But for that you should consult a good dermatologist .Also before giving retinoids one needs to undergo certain blood investigations and take specific precaution (esp in females).So discuss the possibility of retinoids with your treating doctor.Its a excellent tablet for pimples ,but works good for pigmentation too. If you are using skinlite over exposed areas of body then don t forget to use a good spf sunscreen in day time. I hope this answers your question ,if you have any further query you can write back to us. regards, Dr.chawda
