Love it!

The greatest product to heal acne and make skin radiant. A great suggestion from my dermatologist

Great for inflammatory acne

It can be a bit drying but this is wonderful for my inflammatory acne. Retin-a might be better for blackheads and congestion. But this is fabulous for without a rx and lasts a long time

Highly recommend

This is the only product that has helped my hormonal acne. I've been using it for about a year now and my skin has never looked better! Definitely a must have for others who suffer from moderate to severe acne.

It's decent enough to buy twice

I bought this when my friend recommended it. I did see a difference with my acne, to say it was life changing- I'd have to say it wasn't. I just purchased it one more time, unsure if I'll buy again for a third. For an expensive product, the packaging seemed cheap to me.

Cleared my skin

Duality quickly became a staple in my skincare routine once it was recommended to me by my facialist and I witnessed how it cleared my skin tremendously. The texture is nice, and it doesn't feel drying at all. Go easy at first before you start using it every day to get your skin adjusted to it. Would definitely recommend for people with acne prone skin!

not for the whole face

I don't recommend putting benzol peroxide on the entire face. It is just too irritative and makes your face red. I think it might lead to pigmentation for some people. Thus, spot treatment for BP would be better and use the retinol part for the entire face.

so far, so good

I've only used this for two weeks, but so far, I like it. It hasn't cleared my breakouts yet, but I knew this wouldn't happen overnight.

Not for sensitive skin

This did nothing for my acne. Perhaps my skin is more sensitive than I thought because this was extremely drying. There's no way I could use this daily, let alone twice a day. I started off trying to use it every other day and quickly realized that was too much for skin even if I used a moisturizer on top. I decided to use it 2-3x a week to help reduce the extremes dryness of my skin and sometimes would use a very light water based moisturizer prior to duality. I used it for months until I finished the product and did not see any positive results. I would not recommend this to anyone with sensitive skin.
