Rated 5 out of 5 by from My favorite serum for the day [This review was collected as part of a promotion.] 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.

Rated 5 out of 5 by from BEST PRODUCT This is the only product that has been able to save my flaky, dehydrated skin. I have used countless moisturisers and face masks, but nothing did the trick like this serum. After only a few days my skin looked plumper and more hydrated and I no longer struggle with flakiness. I use this every morning and in the evenings I use the regular Y Theorem Repair Serum, which is also amazing but a little too heavy for daytime use. I also add a few drops of the Hyaluronic acid booster for extra hydration.

Rated 5 out of 5 by from It does its job. I have a combination skin and decided to order this formula, and it's not heavy at all when I wear this product. It's super light serum, which penetrates through my skin as soon as I apply it. I tend to have breakout easily, and I pick my acne. The night I use this product, and when I wake up in the morning, I can see that this product heals my skin. It's pricy, but it does its job!

Rated 5 out of 5 by from Absolutely Love it I reluctantly bought the light serum, because of the price being so high, but I am so glad that I did. I suffer from really bad rosacea and blotchiness so was wary about trying something new on my skin which might cause my problem skin to become worse than it already is!! How wrong I could be - this serum is absolutely wonderful. I had no reaction whatsoever, my skin absorbs the serum well and I can apply make-up straight after. I cannot put too many creams on my face due to breakouts and I find this is enough for my skin. The red patches are gradually fading and the lumps and bumps hardly notice at all now. I am even applying less foundation every day as I don't need to camouflage so heavily any more. Thank you so much for a really lovely lightweight serum that actually does work.

Rated 5 out of 5 by from Amazing... Awsome... life changing This serum is the answer to all the skin problems... its transforrms your skin like anything... its a day and night difference. Acne, scars over exfoliation anything and you think of this serum as a healing solution. I was amazed amd now addicted to it. This has become my holygrail. I have a very prolematic skin which reacts to everything but my reactive sensitive skin loved this serum like its wrapped up in soft cushion of plush. Absolute essential for every skin care junkie like me

Rated 5 out of 5 by from 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!!
