## Customer Reviews

### ⭐⭐⭐⭐⭐ This stuff works wonders
*by G***R on June 22, 2023*

I noticed this product within two applications. Now that I have used it for over three weeks It has been wonderful. Moisturizes, minimizes lines, and seems to brighten and tighten skin. I am impressed!!

### ⭐ Thoroughly unimpressed
*by C***R on September 3, 2019*

For the price point, I was highly disappointed. My dermatologist told me to use a product for at least 2 months (2 menstrual cycles) because your skin changes so much during each cycle. I gave it 3 months with this 111Skin Y Theorem and BARELY saw any results. If you are looking for an AMAZING serum, I am using the Drunk Elephant TLC Framboos Glycolic Resurfacing Night Serum and I cant say enough good things about it. Hope this helps all the gals out there!

### ⭐⭐⭐ Good, but far from great. Expected much more for the money
*by A***A on April 22, 2019*

I really like it, it feels good, but honestly did nothing better than other serums, and it is pretty expensive, we would expect a great different result... definitely do not recommend it
