Hi Doctor, I am a 42 year old mother of two. I have, for the last 3 months, developed pigmentation on my face and neck, more pronounced on my neck, and have gone through treatment using a combination of 3 creams prescribed by the doctor. He says now that the superficial pigment is gone, however, the deeper pigments are still showing. now he has put me on the following medicines, one to intake called antioxidant, and the other, a drop to put on the face/neck once everyday, called iklen (says it corrects and shades off brown spots) and asked me to come back in 2 months. Can you advise? thank you.
