Hello and welcome to healthcaremagic Tamil nadu has strong sun throughout the year, thereby tanning the exposed skin of face and hands. Indian skin is specially prone to tan even to the slightest sun-exposure. If I was your treating doctor I would have asked you to use a broad spectrum sunscreen, that which offers both UVB and UVA protection, throughout the day. A skin lightening cream containing one or more of the skin lightening agents e.g kojic acid, glycolic acid, Hydroquinone, arbutin, magnesium ascorbyl phosphate etc can be use once or twice daily on the darker areas of face and hands, to gradually fade away the tan regards
