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 hero product created by Dr. Alexandrides that inspired the 111SKIN range. Originally created to treat trauma after surgery, the restorative effects of the Repair Serum can aid in reducing redness and soothing irritated skin by providing it with reparative ingredients. Containing NAC Y2, the formula provides skin with the optimum conditions for enhanced collagen, elastin, and hyaluronic acid production.

The result is a reduction in the appearance of fine lines and wrinkles, plumper looking skin, and a rejuvenated complexion. Rich in texture, only a small amount is required to nourish the skin, and it makes the perfect companion to take on holiday for use after exposure to extreme conditions or sun. It is also excellent for use on scarring.

 

DISCOVER THE KEY INGREDIENT, NAC Y2


  • NAC Y2: A fusion of three ingredients that all improve antioxidant levels, providing the optimum environment for collagen and elastin production and reducing the effects of environmental damage.
  • NIACINAMIDE: A form of Vitamin B3 which restores important lipids in skin, while providing anti-inflammatory and brightening properties to combat uneven skin tone and blemishes.
  • CALENDULA: An anti-inflammatory botanical extract that stimulates healing and nourishes the skin.

Amazing for sensitive skin

My super sensitive skin loves this serum! Since I started using it I no longer have any red patches and my skin also looks brighter and smoother than before.

Amazing

I received this in an Ipsy bag and was sold on the product immediately. This is the third time I’ve purchased it, and will continue to do so! Improves my skin almost immediately with no irritation or drying it out.

Is it worth it?

Yes. I was shocked. It’s the only thing I ever tried that made a visible difference the first time I sampled it. In other words, yes it works.
