None: Alpha hydroxy acid or glycolic acid actually is known to increase skin sensitivity to the sun and can increase the chance for sunburn.

To be honest: While you'll get modest benefits from chemical exfoliation with products like over the counter strength alpha hydroxy acid containing products, if you are really interested in a stronger effect seek the input of a dermatologist who can offer stronger chemical peels based off of glycolic acid or trichloroacetic acid.

Hydroquinone cream: Try hydroquinone cream. Rub in a small amount 2 times each day. You can find a 2% hydroquinone cream over the counter in most pharmacies. Natural liquorice extract is another treatment that works but is usually not as effective.
