Hello. Thanks for writing to us at healthcaremagic
UV A part of the electromagnetic spectrum is mainly responsible for tanning.
Sunscreen is an essential part in the management of tanning.
I would suggest you to use a broad spectrum sunscreen, throughout the day.
Reapply 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, would be suitable.
You may find one such 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 Tretinoin,
Mometasone furoate, Azaleic acid,
Hydroquinone,
Kojic acid, Arbutin,
Glycolic acid, licorice extract, Niacinamide, Vit C etc. These creams are very effective prescription products.
I would suggest that you visit a dermatologist in your region for more details and the needful.
Along with the creams, you may also opt for a few sessions of chemical peeling (e.g glycolic peel) from your dermatologist for faster results.
