Brief Answer: Hi Detailed Answer: Hi Thanks for posting your query on XXXXXXX Blackheads are mostly removed normal. These may be removed for cosmetic reasons and tend to grow back. These can be effectively removed in beauty parlors, but you need to take caution as per the chemicals used. Sometimes the blackheads may start appearing as whiteheads after using medicine on them. In case of skin allergy it is better to avoid any chemical use on face as it may cause permanent damage to skin. If you have dark pigmented patches, then you can try the following: - Avoid exposure to sun. Use sunscreen every time you step out in the sun. - Take fruits and multivitamins that have vit A and C - Lightening creams like kojic acid and azelaic acid can be tried only on the affected areas. But you will need to take it under supervision of a dermatologist. Hope it helps. Dr Vaishalee
