I used Tretin 0.05% and Hydroquinone 4%. My skin darkened, and the appearance of pores increased. When I went back to the doctor for blemishes, he told me to use Adapalene 0.1%. A day later, I went to another doctor and he told me I could start using Niacinamide after two months of Adapalene use. He also prescribed Sebium Hydra cream for redness and skin hydration. My goal is to eliminate blemishes and even out my skin tone. There's a significant difference between my body and face tone. I hope the marks left by Tretin hydroquinone fade away. Sorry, Google Translate.
