Detailed Answer:
Hello. Thank you for writing to us at healthacermagic
I have gone through your query and I have understood it.
UV A part of the electromagnetic spectrum is mainly responsible for tanning.
First and foremost you must use a broad spectrum sunscreen, on all exposed skin including face, throughout the day.
A sunscreen should be broad spectrum to be effective against UV A. It should re-applied every 2-3 hours.
Neutrogena's ultrasheer dry touch sunblock with an spf of 50+ is one such example of a broad spectrum sunscreen and would be available over the counter.
Sunscreen would not reduce already existing XXXXXXX but would help in preventing it and fading it faster along with pigment reducing creams.
At night you may use a cream containing one or more of pigment reducing agents like glyolic acid etc on areas which you feel are darker than your normal skin tone.
Mechanism of action of glycolic acid is exfoliating of pre-existing melanin. Glycolic acid is also hydrating and therefore would moisturize as well as reduce scaling.
