Jan Marini Age Intervention Duality power!

My daughter was having typical problems with her skin, being an athlete, and at the age of hormone changes.  We saw a Derm several times which helped some but generally their suggested products are very gentle and sometimes not effective enough.  I finally asked my sister, who is an aesthetician, on what product would be most effective.  She said she saw many teens as clients and always recommended the age intervention duality.  My daughter is almost 18 now and the only product she cannot do without is her duality.  It keeps her face clear, healthy looking, and is the one product that is worth the cost.  Extremely effective.

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.
