I recently started a new routine that has worked miracles for me. I have good skin now but with quite a few dark marks (and not the death eater kind)
Basically, at night I use Paula's Choice Weekly Resurfacing Treatment
, which is just a 10% AHA solution
And during the day, under sunscreen/makeup/whatever, I've been using Reviva Labs 5% Glycolic Acid Cream.
I’ve only been doing it for just over a week, but already the marks on my cheeks have faded SO much, and I fully expect them to vanish soon. Plus, my skin is super smooth
A cautionary note, I worked up to this, the PC stuff especially is quite strong. I've had both of these products for a long time but only recently started using them both daily (I don't even know why I started doing it) and it seems the two different chemical exfoliators in combination have done the trick.
(nb: I use Rosehip oil to moisturize and I cleanse with the OCM, but I've been doing both of these things for a couple years so that's not what has made the difference.)
Might not be for everyone, just wanted to share because I am so incredibly happy with my skin right now :)
