Pretty great!
I was nervous to try this one, turns out it works pretty well for my skin. My daughter uses it as well and so far we like it!

Works well
Good spot treatment for small pimples. Can be drying so it’s best to use a little bit at first and work your way up to multiple times a day. For larger pimples, it can take a few days to see improvement

My new go-to for blemishes
I have combo skin and I’m in my 40s. I was buying Murad spot treatment for years for my monthly blemishes until I had a bad skin reaction from a new product and needed to speed up some acne breakouts. I stumbled across this and I’m more than pleased. Just a tiny dab on the spot will result in blemishes disappearing in 48hours. Sometimes the next day they’re completely gone! So far no extreme tightness, red marks, or flakey patches either. Also the tube has lasted forever. I’ve even noticed less monthly breakouts since I started using it.

Fantastic
This stuff is wonderful. It works so quickly, and cleared up my hormonal acne in one night. So thankful that I found this!

Works really great!
I used a Benzoyl Peroxide acne spot treatment by Murad and then they discontinued it or changed the formula. When I found this one I was wishing Murad discontinued theirs years earlier! It really does work well for those deep, painful blemishes. A little goes a LONG way!

Drying
It works but I found it too drying for my skin. The area I applied would be dry and scaly for days. Also the product separated for me.

It was easy.
Just one single pack helped me to get rid of my acnes. This product solution unclogs pores as it clears blackheads and whiteheads.

Spot treatment
I use this product to spot treat during the day when I get breakouts. It works to keep skin not so oily as well (especially during hot Texas summers) . It does have a bit of a burning sensation, but I don’t mind this. The container is also difficult when it starts to run low.

Spots be gone!
This is my favorite most effective acne spot treatment, wear it at night when i feel a pimple is coming (or on an active zit) and im not even exaggerating when i tell you that the next they either the spot is gone or reduced dramatically in size. Could be a bit irritating and drying if you overdue it but when done right it clears acne beautifully. also dont forget to use your sunscreen during the day when using this product.

Toooo strong
I read up on benzoyl peroxide and followed all the advice and heeded all the warnings about making sure my skin stayed moisturized. I used it with all the ingredients that are said to pair well with bp and avoided all that's not, yet it still damaged my skin barrier. My skin was red, hot, tight, and somewhere between pebbled leather and sand paper. In a word, it hurt. A lot. I couldn't do anything else but moisturize it back to life. (Even my usual moisturizers stung like crazy — I had to get a whole new moisturizer that didn't hurt.) Stopped using this bp immediately!
