Hyperpigmentation

[u/Active_Education_857]

I am suffering from hyperpigmentation as long as I remember. I am using tretinoin and hydroquinone and my 5 years old spots started to fade but recently I suffered from an allergic reaction (I don't know what caused it) and my whole body was ichy and due to which I got ezema at one place, and when it healed a huge scar appeared which is even worse than my previous hyperpigmentation. It's making me feel everything was a waste. Idk how long it will take for it to go. Any suggestions to fasten the process?
