[/INST] Hello, Welcome to Chat Doctor. I understand that you are concerned about the tanning you have acquired due to excessive sun exposure. Most of the people will acquire more pigmentation as age increases, we call it facultative pigmentation. Lot of factors determine it, most important being sunlight, others include dust, pollution, smoking, less HY Chat Doctor. Treatments should be aimed to bring your pigmented skin back to your normal skin tone and make the skin tone even all over the face. The most important product will be a sunscreen. Half an hour before going out, apply a sunscreen and reapply it every three to four hours. You may apply a compact powder over the sunscreen so that there is a Matt finish. I would recommend you to use a face wash twice a day ideally a one containing glycolic acid as it helps in exfoliation and to even out the skin tone.(e.g. : Mel awash face wash)At night you may apply a lightening cream containing 2% comic acid over the face before going to sleep. You may consult a dermatologist practicing cosmetology for few sittings of chemical peels for faster improvement. Hope I have answered your query. Take care. </s>
