NAC Y²™️

The key ingredient NAC Y²™️, evolved out of Dr. Yannis’ collaboration with European biochemical engineers testing an ingredient called NAC on astronauts in Space, an extreme environment where skin ages more rapidly. 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.

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.

Can this moisturiser be used during the day?

It can be used during the day to help skin against extreme dryness or cold climates, but as this cream contains Retinyl Palmitate, we recommend wearing with an SPF during exposure to sunlight.

What age range is this suitable for?

We recommend this product for anyone seeking an advanced solution to the signs of ageing.

Will this target and reduce pigmentation?

Areas of hyperpigmentation are treated with brightening active ingredients, diminishing visibility of dark areas for an even skin tone.

What are ‘Black Diamond Particles’?

Black Diamond Particles are microspheres that gently exfoliate and accelerate the transport of essential-youth restoring ingredients into the skin.
