    A life changer

    For 5 years I have suffered with the worst rosacea - in my 40s. With short hair there was no hiding, my skin not only looked absolutely horrific but the pain was agonising - I spent 3 years back and forth at doctors and hospitals with absolutely no results apart from a cream which not only burned my skin but made it 10 times worse. I had never ever felt so low in my life. No exaggeration. After a lot of self research I found this - and within 3 weeks my life changed again, my skin started to clear, no more agonising red lumps, itching or burning and the redness started to clear. 6 months on my skin is continuing to improve. I cant change the damage done, but now I have normal skin with a light covering of Make up. Dont Panic at the cost, this is worth every penny and more besides - using it just once a day, one pump, it lasts months - serious value for money - And trust me, I spent about 1000 on various lotions, potions, heartache and make up to try before this miracle product. Life changing for me, I can face the world now. Thank you 111 skin.

    My favorite serum for the day

    I have very sensitive skin that gets oily easily. The Y Theorem Repair Light Serum is my favorite serum and it's a important part of my daily routine. It absorbs very quickly and hydrates the skin very well. And there is absolutely no skin irritation.

    Best repairing serum ever

    This serum works wonder to my combination - oily skin it’s light weight, easy to absorb, and does not clog my pores, and it really helps reducing my acne scars after I get an extraction. I do spectra laser once a month and this serum helps soothing my redness as well! I’m on my fourth bottle already! Can’t live without it!!
