A concentrated, lightweight serum that uses a powerful formula to deliver fast, intensive ageing and pigmentation fighting results.

This incredibly powerful serum is a more intensive version of the original Y Theorem Serum. The formula melts effortlessly into skin while the black diamond particles aid deeper delivery of active ingredients. This serum helps to improve firmness and elasticity by encouraging collagen and elastin production in the skin. The serum is a powerful solution for hyperpigmentation, discolouration and uneven skin tone. Hydrate, volumise, smooth, brighten, and even the complexion with this intensive serum.

Mmm *

First and foremost, I love the smell of this serum (along with the few other Celestial Black Diamond products I've succumbed to). I am super sensitive to fragrance- so much so that if I had a superpower, it would be my spidey sense for aromas, especially ones that often become obnoxious the longer you're exposed to it. This potion is light but delightful, which applies to both its scent and how it sinks into the skin (perfect for sensitive skin). I am not in the same echelon (nowhere near) as those who can afford such an indulgence, but nevertheless I will buy this again, which is why I am taking the time to review it (111SKIN offers a wee discount for your two cents). As for the packaging, the only thing I've had issue with are the lids staying on. Fortunately, though, it hasn't seem to affect the product within the bottle.

Wouldn’t be without it!

The only serum I have total faith in! Not only does it feel good on your skin (no stickiness) I’ve had comments from my friends saying “whatever it is I’m using - don’t change”’!!

Great product.

I like how the serum absorb on my skin really quick. The lightly fragrance smell is subtle which I like. It hard to tell if the serum does wonder to my skin after just only few usages, but I hope it will improve some fine wrinkles in a few month. One thing I dislike about this product is the packaging feel a bit flimsy, every time when I pull the cap the pump twist loose and to my opinion with the price I expect the bottle to be properly sealed and more luxurious than it is. I would minus a star due to the packaging is not so great.
