Revitalise the complexion with the 111Skin Y Theorem Concentrate, a seven-day skincare program delivering the power of the NAC Y² complex to help hydrate and renew the skin.

Ideal for use on damaged skin, the NAC Y² is at the heart of this powerful formula. The complex contains a potent antioxidant-rich combination of amino acid L-cysteine, aesculus hippocastrum extract and ascorbyl phosphate, a stable vitamin C derivative.

Designed as an effective seven-day program, the treatment works to repair and rejuvenate damaged skin, reducing the appearance of fine lines and wrinkles, while boosting elasticity for a radiant, renewed complexion.

Amazing!

I used this from an Ipsy deal and let me tell you.. after using this twice it did amazing things for my dry skin. I used it for the 7 days and couldn’t wait to use it. This is amazing stuff and now I am hooked. My face is clearer, way softer and has helped with my dark spots. IN LOVE!!

YES!!

I love this product! I did have to come to the reviews initially to make sure it was supposed to smell as it does. However, if that means we are getting the purest product I am all for it. I can tell my skin looks healthier and just has an overall glow. I have bought this a couple of times now and will continue to do so.

seems to have some effect

I only used the purple box for a week and I guess I started to see some effect. Will continue to buy the black box to see how it goes

Amazing Healing Powers

I’ve had two sessions of Broadband Light Treatment. The first time I used the product recommended by the esthetician, and the second time I used this set of concentrates. The difference in healing was amazing! I healed so much faster the second time using the Y Theorem Concentrate. My skin not only looks healthier after using this product, but it IS healthier! I can see where this product would be great anytime, but it is perfect for applying after a procedure. Like a magic potion! Definitely recommend. The scent is very potent, but I stopped noticing it as much after the first use.
