Holy Grail

I used an entire bottle of the regular Duality, but the Duality MD takes it to a new level! With a higher percentage of retinol (1% compared to 0.5%) I have absolutely loved it so far. Great product and as seen above, its my holy grail for adult acne.

I love Marini!

I am 35 and I believe the earlier you can start with good products the better. I have used Jan Marini for the last 3 years and I LOVE it! It has helped so much with my acne!!!

Can't live without!!

I tried going a month without using this JM Age Intervention Duality, and my face became very angry at me! I have a combination skin, but my T-zone, especially my chin, will break out if I don't use this product! Please don't ever discontinue this product!
