Best Treatment for Post Acne Dark Spots?

[BraveCake]

Been using tret 0.025% for a couple of days. Have seen little to no improvement. I’m gonna start blasting my dark spot with 0.1% tret now though. If this doesn’t work what’s next? Hydroquinone?

Yes hydroquinone

Azelaic first and tret doesn't do shit for dark spots nga
