I'm curious about who is recommended for and the effects of melasma skin boosters.

I'm considering a skin booster for my melasma, and I'm keeping an eye on Rejuran Healer because I heard it's good for people with thin and sensitive skin. There are so many types of melasma skin boosters, and the recommended users vary slightly, so I'm having trouble deciding which one to choose. I've seen many reviews from people around me saying their skin tone became even and brighter after getting a melasma skin booster. Since my skin is particularly thin, I'm also worried about scarring, and I'm even more interested in Rejuran Healer because I've heard it's safer in that regard. If anyone else is curious about who is recommended for melasma skin boosters or their effects, let's share information together!
