Thanks for the query. Dark spots could mean many things. I assume what you mean is probably post inflammatory pigmentation. Targeting through a single agent may not always be fruitful. Meet a qualified Dermatologist to learn more about the diagnosis and treatment options. Combination of different therapeutic agents is always beneficial. Revlite I.e. Q-switched Nd YAG laser has been available for stubborn pigmentation and can be helpful when topical creams fail. Hope it helps.
Next Steps
You can call for few centres in your neighbour hood clinics, Q switched laser is a standard treatment option and shall be available for sure.
