I think I used it for nearly a month and all I can say is that its good products if you use them consistently

Wasn't expecting much honestly

I mainly got this because of my hyperpigmentation. I have darker skin and my spots usually take forever to fade so I really wasn't expecting much from this. Been using it for a few weeks now and my skin definitely looks more even. The marks on my cheeks aren't as noticeable and my skin just looks healthier overall. Also didn't irritate my skin which was my biggest concern. Still using it but so far I actually really like it.

second bottle & no more red bumps

Same chicken-skin texture and red bumps on my upper arms forever. Couple months of nightly use and you can finally see actual skin instead of irritation. On my second bottle now.

forehead lines are fading

The lines on my forehead were freaking me out because my mom got hers in her late 30s and I was terrified mine were starting too. But after two months of using this, they look way softer and Im going to keep using it until they are completely gone.
