Description

The inspiration for 111SKIN, Dr Yannis originally developed a super serum to aid post-surgical scar healing. Word spread quickly about this powerful formula and its incredible ability to fade discolouration, visibly reduce wrinkles, repair stressed skin, protect against sun damage and environmental aggressors.

Only a small amount of this lighter version of our serum is needed to enjoy the effect. You can expect rejuvenated, nourished, plump skin and it will come to the rescue if your skin’s been exposed to extreme conditions such as the ski slope or safari sun.

The perfect repair serum for oilier skin types and humid environments, our Y Theorem Repair Light Serum NAC Y² will thoroughly and reliably rescue your skin and bring it back to life.

Story

Word of mouth. When Dr Yannis began giving his special formula (known then as “Dramatic Healing Serum”) to his post-surgery patients, he was satisfied knowing that thanks to his groundbreaking NAC Y²™ formula, their scars would be dramatically improved. What he didn’t expect was for his patients to keep asking for more. The formula was so effective at creating a firmer, stronger, repaired complexion it became a key part of their facial skincare regimen. Dr. Yannis realised quickly that he could help a lot more people to feel amazing in their own skin. He developed his healing balm into Y Theorem Repair Serum NAC Y² - and the rest is history.

NAC Y²™ 

NAC Y²™

World-renowned plastic and reconstructive surgeon, Dr. Yannis Alexandrides MD FACS’ sought to create a product to encourage optimal healing for his post surgery.

The exclusive ingredient NAC Y²™ was created by Dr. Yannis in collaboration with European biochemical engineers testing an ingredient called NAC on astronauts in Space, one of the most extreme environments for skin. The results were astounding.

This revolutionary ingredient complex is scientifically proven to promote Glutathione production and encourage cellular renewal to visibly repair the skin and target the signs of premature ageing.

“Providing the skin with NAC stops DNA degradation and halts the ageing process on a cellular level,” explains Dr. Yannis.

Dr. Yannis used this complex to develop his first ever formula, the Dramatic Healing Serum, the forerunner to our Y Theorem Repair Serum NAC Y²™.

The NAC Y²™ complex is at the heart of all of the products in the Reparative collection.

  • NAC Y²™ 

    Stimulates effectiveness of the most powerful intracellular antioxidant: Glutathione along with two additional ingredients: Escin which boosts circulation and oxygen capacity which are essential for healing and Vitamin C, an antioxidant vital for creating collagen.

  • Vitamin C

    A potent antioxidant vital for synthesising collagen in the skin. It also works on pigmentation, fights free radicals and repairs and protects against UV damage.

  • Liquorice Root

    A potent botanical tyrosinase inhibitor that brightens, tones and reduces hyperpigmentation.

HOW TO APPLY

After cleansing, distribute 1-2 pumps between your fingertips and apply to your face and neck in an upward motion.
If used as part of a 111SKIN regimen, follow with 111SKIN Y Theorem Day Cream NAC Y² or Y Theorem Day Cream Light NAC Y².

You need to try it

I tried it first in the usual, not light version, which felt too thick for my skin type, but results truly impressed.

Later during online consultation I got the recommendation to try Y Theorem Repair Light Serum NAC Y2. And this is exactly what more oily skin needs

I have problem with redness on my skin and just couldn’t believe my eyes in the morning after first use, how much it improved the skin! I love this product, it does magic and I am very happy 🙂

BEST PRODUCT

This is the only product that has been able to save my flaky, dehydrated skin. I have used countless moisturisers and face masks, but nothing did the trick like this serum. After only a few days my skin looked plumper and more hydrated and I no longer struggle with flakiness. I use this every morning and in the evenings I use the regular Y Theorem Repair Serum, which is also amazing but a little too heavy for daytime use. I also add a few drops of the Hyaluronic acid booster for extra hydration.
