Shielding and treating the skin, the Protective Duo utilises our signature ingredient, NAC Y2, to protect and repair stressed skin. The Y Theorem Serum was designed and bottled as a result of witnessing significant healing responses post-surgery. Boosting collagen production, supporting cell regeneration and improving elasticity in the skin, the serum is ideal for those whose skin have faced any element of trauma or exposure. Complimented with the NAC Y2 Pollution Defence Booster, this complexion defence protects the skin from physical and blue light damage by combining a powerful complex of peptides and antioxidants. Together this fortifying duo helps to maintain a healthy complexion away from free radicals, inflammation and a weakened skin surface.

 

1 x NAC Y2 Pollution Defence Booster - 20ml

1 x Y Theorem Repair Serum - 30ml


 

Apply 2-3 pumps of the Y Theorem Serum, mixed with 2-3 drops of the NAC Y2 Pollution Defence Booster before pressing into the skin.

Great Stuff

I first received a full bottle in my Boxycharm subscription. I have rosacea and am allergic to propylene glycol which is in many beauty products. No reaction at all from this product. My skin looks so polished and youthful. Appear of fine lines gone. I purchased 2 bottles.

Amazing product!!

From the moment I applied this serum, my skin became plump and wrinkles and pores became less noticeable. I feel that my dark circles have become thinner. I will continue to repeat this product.
