111SKIN’s Y Theorem Repair Serum

The one product in my skincare routine I can’t live without. I recommend this product to almost all of my clients post peels and micro-needling. See how I use it here post Vampire Facial for flawless recovery.

I started using the Y Theorem Repair Serum a few years ago and it is the one thing I don’t even blink about when I need to order a new one. This one serum will rejuvenate your skin and fight the effects of aging. Formulated with antioxidant-rich plant extracts and vitamins, this powerful serum helps to restore a youthful appearance and complexion. It works amazingly after micro-needling treatments or post-peels.

With consistent use, I notice my skin feels and looks amazing. Results were more hydrated, fewer fine lines, and an even complexion. I like to use it morning and night. In the AM, my skin stays hydrated all day plus my makeup stays put longer. In the PM, I noticed my skin looks incredible when I wake up in the morning. My skin feels plump and hydrated all day.

The texture is a watery gel-like consistency that absorbs very quickly. I noticed if I use too much it turns sticky but that goes away when I apply my moisturizer. 1-2 pumps are really all I need for my neck and face anything more and it gets sticky plus at $350 a bottle let’s just not waste any! There is a soft fragrance but I like it. It smells clean. The fragrance is listed as the very last ingredient so there isn’t much in there and I find it dissipates within seconds.
