Hello doctor, I have these brown spots since the last 20 years. It grew from a small spot to this big in all these years and it is still spreading slowly. It does not itch, neither does it pain but when I get out in the sun, I feel a burning sensation all over the area. I once used Skinlite cream and the spots were visibly lightened but they reappeared. I want to know what medication I should take and what precautions to take so that it does not spread anymore. Is there any way I can get rid of these spots? I have attached the pictures.
Hello. I have seen the images (attachment removed to protect patient identity). The triggers include sunlight or any harsh irritant chemicals. Skinlite has Hydroquinone which is more than sufficient to mask any pigmentation, but not cure it completely.  From the symptoms, I strongly feel it is lichen planus pigmentosus or ashy dermatosis of Ramirez. Both of them can exhibit similar features. In my opinion, you should get a skin biopsy to confirm the activity status of the problem and also the severity. We can then decide the best treatment based on the reports. I strongly recommend applying sunscreen and covering the area. For more information consult a cosmetologist online -->
