I just got this today and put it on around 1:00 PM, it's now 10:30 and I am ALREADY seeing results!
I have two very dark scars in the corner of my mouth from an overzealous orthodontist, I've tried hydroquinone, vitamin c, retin-a to try to fade them, basically nothing has worked.
This is designed for liver spots, but hyperpigmentation is hyperpigmentation (I dunno how effective it is for redness).
Anyways in those 9 hours and a bit I am already seeing results! It's definetly starting to get lighter visibly. I'm super excited and crossing my fingers that it continues to work...I can't wait for these scars to be gone, they've been there for over 4 years now...
It's very pricey, about $52 USD on Sephora for a pretty small bottle, but it's definetly more than enough if you're only applying it to spots.
It stings a tiny bit when you put it on, but it fades quickly - you're supposed to use this at night and use a sunscreen during the day, but I couldn't wait to try it out
