I've been using DuoGen since I set a 2023 new years resolution, and I have never looked back nor ever considered switching. I have sensitive skin and have to be careful with skin products, but DuoGen gave me NO negative reactions, and the application is so smooth and feels so luxury it's still my favourite part of my nightly skincare routine! I no longer suffer any breakouts ever, and never have to worry about tired, dry, sagging skin. Love Love Love and would recommend to everyone.


Early days yet, but I’m seeing an immediate result and wish I’d taken skin care more seriously about 20 years ago.


As I’m Turing 57 in January and ex qualified personal trainer nutritionist I’ve always looked after myself both body and soul along with taking care of my skin for obvious reasons. Tried a number of vitamin C products over the years most of which are either too strong or not natural despite claims. This works perfectly as it’s both light and clearly doesn’t irritate my skin.
Use mainly at night 2-3 times a week. Quality product at a good price.


Game changer
Had stress related rosacea for almost 40 years and was advised by a dermatologist to include niacinamide into my skin care and hey presto almost a 100% improvement
Anyway give it a go and who knows


Great product! Smooths fine lines and works perfectly with the rest of my night skincare routine.
