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.

Seen a difference after first use

This product is amazing. I started to see a difference after a first use only. My skin was so much more plump and hydrated with a glow. I initially got this product for my rosacea but it has helped with things that i didnt even know needed fixing. Im hoping to clear this redness within 2 weeks and things are looking good so far. Great stuff.

Serum

This product is unbelievably wonderful. However, it doesn't last very long. I only used it for about 25 days and almost gone.

Addicted to this product!

I love testing and trying new serums and have honestly not come across any serum that makes my skin feels this soft and revitalised. It’s a pity that it’s a bit pricey(will normally wait for a promo) but I use this sparingly and sometimes switch with my less expensive night repair serum in order for it to last even longer (previous bottle lasted me around 8-10months) I use it in the evenings before my night moisturiser and will guaranteed wake up with great skin!
