Tanning occurs due to exposure to UVA and UVB rays of sunlight without protection. In fair conplexion it can cause sunburns as well.

After sun exposure, an immediate tanning is noticed due to UVA exposure. This clears away on its own in a few hours after sunexposure ends and occurs due to redistribution of melanin rather than new melanin production. It doesnot need any treatment. Delayed tan occurs after a few hours due to both UVA and B rays by excess melanin production and takes weeks to months to clear depending on its severity. However, neither of the two are permanent if adequate measures are taken.

The first step would be to ensure future sunprotection by use of umbrella, hats etc and a broad spectrum sunscreen with good SPF and PA rating.

For removal of tan quickly, products with lightening property which prevents melanin synthesis can be prescribed. Glycolic acid, kojic acid, arbutin, azelaic acid etc may be prescribed by your doctors for regular use. Apart from this, chemical peels with exfoliating agents like salicylic acid, glycolic acid and trichloroacetic acid can remove the damaged upper skin layer and give fast clearance of tanning. For deeper pigment which does not respond to anything else, Q switched Nd:YAG laser is sometimes recommended.

Using OTC products and parlor procedures on sun damaged skin can cause irritation and burns and even worsen the skin darkening.

Visit your dermatologist to know what tan removal procedure would be best for you and how you can maintain your tan free glowing skin.
