<s>[INST] Hi, I have pigmentation on the face, due to that my skin is very bad with wrinkles what is the home remedy since i have spent lot on treating pigmentation. Now i request if you have any simple method of treating this apart from pigmentcontrol acid etc... [/INST] Hi, The dark pigmentation on your face area is known as Post Inflammatory Hyperpigmentation/ Post Inflammatory Hyperkeratosis (PIN) due to the activity of melanocytes which are the color producing cells. It is a condition of the skin arising from over activity to the skin resulting in healing with pigmentation. If I were your dermatologist then for dark pigmentation I would have suggested you to use atelier acid cream or Comic acid cream or glycolic acid cream or licorice extract or routine creams at nighttime in guidance of dermatologist. Most importantly you should do sun protection. Take care. </s>
