The Y Theorem Repair serum harnesses our unique NAC Y2 formula to protect and repair stressed skin, visibly reducing the appearance of fine lines and wrinkles.

This Repair Serum is the original product created by Dr. Alexandrides that inspired the 111SKIN range. The Repair Serum significantly boosts collagen production, supports cell regeneration and improves the elasticity of the skin. The result is instant hydration, effective volume enhancement, and a reduced appearance of fine lines and wrinkles.

Discover the key ingredient: NAC Y2

Say goodbye to dull skin!

The serum is really gorgeous! My skin is very sensitive, textured (due to acne scarring), dry and oily in t-zone, and since I use the product (about 10 days), I see a great difference. I have improvement in ten, calming, radiance and the texture is smoothened and even. Also, my pores are almost invisible. Feeling is amazing!

Loving the 111 Skin products

I have just started to use the 111 Skin products since lockdown, I moved from Australia and the products I was using would not ship to the UK. (I'm 47 years old)

My skin went very dry because of the hardness of the water here, so it has taken time for it to settle. Fast forward 3 months and my skin is looking and feeling amazing. I suffer from redness from broken capillaries and have always had sensitive skin, I have found that the redness is certainly a lot calmer and my skin is plump.

The only downside is that you cannot tell when the serums are running low because of the bottle.
