Hello. Thanks for writing to us at healthcaremagic You have a condition known as Melasma. Melasma can present light brown to dark brown to bluish pigmentation over the cheek bones/malar area, nose, forehead, upper lips etc. It is idiopathic in most of the cases. Sunscreen is an essential part in the management of any facial pigmentation including melasma. I would suggest you to use a broad spectrum sunscreen, throughout the day and re-apply every 2-3 hours. It should have both UV A as well as UV B coverage. A broad spectrum sunscreen that has a minimum spf of 30 or more, would be suitable. You may find a suitable sunscreen OTC from a drug store Or you may also get it prescribed from a dermatologist. At night you may use a skin lightening cream, containing one or more of the following active ingredients e.g Azaleic acid, Tretinoin, Hydroquinone, Kojic acid, Arbutin, Glycolic acid, licorice extract, Niacinamide, Vit C etc. These are prescription products and therefore you need to talk to your dermatologist. The cream that you have been using contains a combination of tretinoin and hydroquinone, both of which are irritants and can cause redness and patches on face, specially when you first begin therapy it. Therefore, at the start of therapy it is advisable to use this cream for just 2 hours every night Or use it every alternate night, till your skin gets adjusted to it. Along with the creams, you may also opt for a few sessions of chemical peeling from your dermatologist. Melasma may take time to respond and you have to be patient with the treatment and follow up regularly with a dermatologist. Your dermatologist might change or modify treatment according to the response. Lastly, Melasma can recur therefore you have to be on a maintenance regimen. It is important to use a sunscreen, every 2-3 hours, specially outdoors, throughout the day and a maintenance skin lightening cream once daily at night. You may take sessions of chemical peeling once a month to maintain the improvement. Regards
