Hello. Thanks for writing to us at healthcaremagic
I would suggest a broad spectrum sunscreen, that which offers both UV A as well as UV B protection throughout the day.
It is important to select the right sunscreen for desired effects.
A sunscreen with minimum 30 SPF would be adequate. It should mention both UV B and UV A coverage.
A sunscreen should be applied every 2-3 hours whenever outdoors. It should be applied in adequate amount to be effective as per the spf mentioned.
A quantity of 3 ml is adequate for each leg and the same quantity for each arm.
At night you may use a cream containing one or more of the skin lightening agents e.g
kojic acid,
glycolic acid, or
hydroquinone etc once daily at night to gradually fade away the pigmentation/Tan.
These creams are available on prescription and I would suggest that you seek an appointment with a
dermatologist in your region for a prescription of one of these
You may also opt for a few sessions of chemical peeling from a dermatologist.
