Now available in a Light version, The Y Theorem Repair Serum NAC Y2 is the OG skin care product that started this renowned brand - and we can see why!.

Fusing the powerful and patented NAC Y2, exclusive to 111SKIN, this super serum quickly gets to work creating a firmer and stronger complexion. Ideal for rescuing skin that's been exposed to harsher conditions (think safari sun or ski slope rays), it quickly rejuvenates and nourishes by promoting the body's natural antioxidant glutathione, supporting collagen and elastin production. Not only that, but this potent concoction has an incredible ability to fade discolouration, visibly reduce the look of lines and protects against sun damage... Considering this has been tested in space, we aren't surprised it's so hardworking.

Massage Y Theorem Repair Serum sparingly onto the face and neck with a gentle patting motion. Apply the appropriate day or night cream on top of the serum.

Formulated by globally renowned Harley Street cosmetic surgeon, Dr. Yannis Alexandrides, 111SKIN has quickly become the go-to for skin-savvy celebrities (we're talking everyone from Priyanka Chopra to Margot Robbie), beauty editors and skin care obsessives alike. Now you can reap the rewards of this highly effective range in the comfort of your own home with the Y Theorem Repair Serum Light NAC Y2.

    I've used several mini bottles from this serum. I simply adore it.

    Terrible for money
    1 out of 5 stars
    The second I opened this serum, I winced. The fragrance is disgusting and artificial. I put it on and I felt a silicone-like film on my face. Wouldn’t mind this if it were a very cheap brand, but for this price absolutely unacceptable.

    Just ok...
    3 out of 5 stars
    I absolutely hated the rose gold face mask as well as the black diamond eye mask from this brand. Especially due to the incredible amount of perfume in it. So was very sceptical when trying this. Turns out it‘s half that bad. Perfume is ok, at least it is not overpowering and does not linger. I actually liked the lightweight consistency and found it sinked in right away. I used it for 3 weeks without seeing any results. So probably not quite for me, but at least it did not cause any irritation nor migraines (like the two masks from the same brand did).
