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 an unbelieveably effective product. I am 56 years old and have experienced hormone/stress related acne since I was about 13 years old. I have used many, many products including benzoyl peroxide soap, proactive, retin A, Acutane, sulfur, borax, etc. Never have I been acne free for more than a day. I found I was extremely sensitive to the OTC benzoyl peroxide products and they made my skin breakouts worse!!! That is until today or rather the last few weeks. My skin is clear, really for the first time in my life since my teens!!!! I LOVE THIS PRODUCT!!! I can't tell the difference between JM Age Intervention Duality and the same product with MD in the title. Both work for me!!! Thank You Jan Marini!!!

My skin savior. I had acne and acne marks. This is the only thing that helped it also has anti aging benefit besides combating acne. The retinol and benzoil peroxide works alongside to provide the best result for clear skin. Perfect to use with skincare management system from Jan Marini. Don't forget to use moisturizer because it tends to dry the skin as it dries out the acne.
