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.

Great except for smell

Product really changed my skin over 7 days and I am hoping to see the long lasting effects. The only thing that bothered me and my husband was the smell - it was pretty strong but for 7 days I was personally fine with it. I would not buy it monthly but possibly every once in awhile when your skin needs a pick me up.

Hi Ashley,

We're so glad you felt the benefits of our wonderful Y Theorem Concentrate. This is one of the most potent forms of treatment for the skin and subsequently is formulated with the raw ingredients which we do not scent so as to provide the optimum results for your skin. Whilst it may take a moment to get used to and I'm glad you agree that the results are worthwhile.

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.

Concentrate

After using the concentrate my skin looked fresher and healthier. After too much sun tanning my skin was getting drier but with a little help with the serum it is slowly recovering.
