Product Details

Web ID: 1643164

Stimulate collagen synthesis and boost elasticity of skin with the Theorem Repair Light Serum from 111SKIN, a brand who created the patented NAC Y2 formula using knowledge from space scientists responsible for the well-being of astronauts. Skin ages faster in space because of environmental extremes, including radiation, pollution and high altitude, which inspired the production of the brand's anti-aging range to protect skin from external stresses.

Suitable for oily skin, the luxurious serum is enriched with calendula plant extracts that possess powerful healing properties and contains the highest strength NAC Y2 formula with vital amino acids that work to support cell regeneration. Visibly reduces the appearance of fine lines and wrinkles by intensely hydrating skin and protecting skin from environmental aggressors to leave you with a radiant, youthful-looking complexion. Paraben, paraffin, silicone and sulphate free.

Lovely light-weight serum!

I received a sample of this - and like with every 111SKIN product - you know you will receive a quality product and one where a little goes a long way. This is a fantastic serum to sit under moisturiser, SPF and make-up and the texture is beautifully light. However - as with all 111SKIN products - they pack a punch in your wallet and I can not justify this level of expenditure, despite the very good results.

Repair Serum

I received a sample of the 111SKIN Y Theorem Repair Light Serum with my regular Space NK order. Just wow - a beautiful rich serum, that absorbs beautifully, despite its thick texture. It transformed my skin overnight. Downsides: strongly fragranced, when I'd prefer it wasn't. And, have you seen the price for 30ml!?

A treat product

I got a sample of this product with an order recently and tried it last night. I found the texture initially quite gloopy and thick on the skin so it took me a little while to spread it evenly but once I’d managed that it absorbed fairly quickly into my skin. Once absorbed my skin felt silky soft and plumped almost immediately and when I woke up in the morning it felt the same. My partner commented on how nice my skin looked! Unfortunately the price point is a bit high for it to be a future purchase unless it’s a treat item.

Expensive!!

So I received this as a sample, I knew of the brand but had never tried any products and was excited to use. The serum is absolutely beautiful on the skin, it absorbed perfectly and gave a stunning glow. I liked this so much I searched the product to see how much this would cost to buy. I will not be buying this lol! It was nice definitely but €270 is insane

Hydrating but so expensive

Received a little satchet with my last sample, was very excited to try as I have heard good things about this from a family member. It is a thick serum and a little goes a long way (thankfully given the price point). Leaves skin visibly hydrated instantly and throughout the night. However two stars off - one the price point is unaffordable and two it is heavily heavily fragrance.

Repair serum

I only tried a simple size,even though only a small amount is needed I think I would need to try for longer to see results. It is more like a gel in consistency and I feel didn't absorb that well leaving a slightly sticky feel,also I wasn't too keen on the scent,I think it just probably wasn't the right serum fir me,but others would like it,maybe a drier skin texture would enjoy it more.

Lovely serum

Nice gel like serum that applies easily and absorbs well. The serum does have a scent that is pleasant enough. After using this my skin has felt plumped and hydrated. Would definitely use again but realistically I’m not sure I would pay full price for this. Four stars due to price.

Plumping serum

I've been able to use this serum every mornin for over a week thanks to a good size sample in the last gift skincare box. It's a light gel serum which goes on easily and doesn't irritate my sensitive skin. My skin feels plumper and smooth. I would have given it 5 stars but it smells slightly chemically to me.
