I'm 42 years old and I have a Zo medical Melamix 4% with tretinoin .1 %. Can I use on my face and my under eyes area too?

Facial pigmentation is a direct cause of hormones, genetics, and sun
exposure. I would recommend a carefully curated combination of laser
therapy, fractional ablation, Covalent peels, and topical Melarase
creams. To start, use Melarase creams for 4 to 6 weeks: 
AM: Melaclenz, Melapads, Melarase AMPM: Melaclenz, Melapads, Melarase PM +/- Replenish retinoid creamBest,
