I have been suffering from a hormone imbalance and it has caused hormonal acne all over my cheeks and chin. Im 26 years old and it was humiliating.

Not good for sensitive, acne prone skin

New Staple
this has become a part of my nightly rotation. I love the way this leaves my skin. I tend to get closed comedones but the morning after i put this on, they're all gone. Leaves my skin super glowy too. I look forward to the nights i have to use this and wish I could put it on every night!! Plus I heard it's antibacterial so its fighting against any dirt/ pimples.
Great for hormonal breakouts
I love this serum! I tend to get clusters of hormonal pimples monthly and this always clears them up rapidly. It took a few months for my skin to fully get used to the serum and now when/if I do get breakouts, they clear very quickly.
Saved my skin
2 months ago I started getting tons of little bumbs on my forhead (probably closed comedomes) and within 3 uses of this product they have almost completely cleared. I'm so excited to continue using this.
Broke me out
I wanted to like this, but im having the worst break out of my life after trying this. My face is very itchy, painfuk, and burns so bad too.
Strike out for sensitive acne prone skin
This mandelic acid burned when I put it on and was thick/sticky. It also gave me inflamed cystic acne on my chin/jaw line, along with pores on my cheek look huge. I was using Ordinary MA beforehand and never had these issues. Will revert back.
