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 too extreme conditions or sun. It is also excellent for use on scarring.

30ml

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!

Say goodbye to dull skin!

The serum is really gorgeous! My skin is very sensitive, textured (due to acne scarring), dry and oily in t-zone, and since I use the product (about 10 days), I see a great difference. I have improvement in ten, calming, radiance and the texture is smoothened and even. Also, my pores are almost invisible. Feeling is amazing!

Loving the 111 Skin products

I have just started to use the 111 Skin products since lockdown, I moved from Australia and the products I was using would not ship to the UK. (I'm 47 years old)

My skin went very dry because of the hardness of the water here, so it has taken time for it to settle. Fast forward 3 months and my skin is looking and feeling amazing. I suffer from redness from broken capillaries and have always had sensitive skin, I have found that the redness is certainly a lot calmer and my skin is plump.

The only downside is that you cannot tell when the serums are running low because of the bottle.
