how does tazarotene compare with tretinoin for curing hyperpigmentation/melasma?

[Mr Looks]

what concentration do you use and how often to you apply

0.1% gel
Every evening that im not using derma stamp
Let it stay for 1.5-2 hours (if it burns really bad, wash it immediately, i have been using these chemical peels for a long time)
Brand name im using is is zorante if you want to know
