Jan Marini Jan Marini Age Intervention Duality - 1 oz

There remains a sea of products and this one offers a new and unique combo of benzoyl peroxide, retinol, and other pro peptides. I read because of the active ingredients they must be stored in two chambers to mix at the point of use. Whether true or not, I love the fact that I can use more or less of one side based on my own personal skin care needs. JM knows that I need to blast my acne breakout with benzoyl peroxide during a bad break out or early on. At night is when I love to use retinol in this concentrated strength without having to use the BP. Other nights I use as directed.

Anyone unfamiliar with retinol should read up and start using this product. Retinol works! The research at JM backs this up. I am not sure, however, of the percentage of the retinol which is the down size of this product, but I am assuming it is less than a full 1%, which is still strong.

Use every other night until your skin gets used to it then you can increase. Results for me were within two weeks. No break outs either. For those with needs greater than this, Jan Marini has doctors to stock and sell a more potent formula. Start here with this one and you will be happy for many years.

I have used Jan Marini cleanser for over four years and thought I would try Duality. Big mistake! It burned my skin so badly after just four days of use that I had to go to the dermotologist and begin using a Rx steroid creme for dermatitis. I am still under the doctor's care and don't know if I will be left with scars. Be careful with products this strong. Also the seller refuses to address my issues and I have lodged a complaint with Amazon which is now being investigated.

i have tried many products including prescribed acne medication. this is the only one that works without giving me dark spots. i've only had this good results when i took accutane, but i don't want to expose my system for that strong of a medicine anymore. this product has been outstanding and i'm definitely a fan.

i'm using it once a day (evening) and i apply a very thin layer only on my problem areas – cheeks and forehead. sometimes i do get an occational pimple, but they dry out really fast. i probably wouldn't get any, if i used this twice a day.

the only downside is, that this dries up my skin a little bit and that's why i don't use it both morning and evening. using a really good moisturizer during the day helps for the dryness and helps make up go more evenly.

This is a benzoyl peroxide product. It's main advantage is that it does not dry out the skin and cause peeling like other BP products. It works pretty well to control moderate non-cystic acne.
