Extremely Harsh- This isnt safe to use daily. On the third use it burned my fingers so bad I had to put ice on them for a few days. After recovering, I decided to use it 2x a week. It burned my face. After recovering again, I was able to use it once a week with no problems.
No improvements- I went through 2 bottles of it by using it once a week. Never once have I seen an improvement in my skin texture/smoothness, brightness, or hyperpigmentation. I tried it on my body and no luck there.
I think the brand should reformulate this by switching out the glycolic and mandelic acid with PHA and a dash of lactic acid. It is too harsh and no results.
