<bot>: Hello. Thank you for writing to us at Chat Doctor Certainly chemical peeling can improve pigmentation. Glycol peel is one such peel and helps to exfoliate existing pigment/ melanin. A session of chemical peeling is usually performed every 2 weeks. Number of sessions required would depend on the severity of pigmentation. Since you have observed improvement after 2 sessions, therefore, I suggest you to continue with further sessions. However, it is also important to use a topical cream/ingredient which would prevent synthesis of new melanin i.e. re-development of pigmentation. Sun protection is also an essential part of treatment of pigmentation and prevents further sun induced darkening. I suggest you to use a broad spectrum sunscreen, i.e. one which offers both UV A and UV B protection, throughout the day. Regards
