Enzyme-Active Retinol Serum – Limited Offer

I thought I was imagining it at first but 3 weeks in my whole family was commenting on how good my skin looked and asking what I was doing. I took before pic a few days in because it already seemed to be changing so quickly. The after pics are from my 2nd round of the complete line and the improvement is REAL. I'm shook. THANK YOU PROTOCOL!!

I am 68 years young and just coming off chemo and radiation treatments which is so hard on your skin. I have been using Protocol for just over 3weeks and really can tell a difference.

I’m on my 3rd bottle of this product— I never write reviews but I’m a huge fan of this retinol! As a licensed esthetician, I understand the great importance of this ingredient in a balanced regimen and have tried MANY products, often with high price-points. This is the best BY FAR. I experienced no “purge,” no sensitivity, and almost immediate results. This retinol is the unsung hero of the market. If you’ve have negative experiences with retinol in the past, don’t give up until you’ve tried this one. 🙏🏻

I've used Protocol's Enzyme-Active Retinol Serum for two years with great results. My skin has looked amazing and healthy. Just to switch things up, I decided to give Tretinoin a try. I used Tretinoin prescribed by my dermatologist for 6 months and went through the expected purging stage followed by the glowing -skin stage. However, even after the purging stage, my skin just wasn't nearly as good as it had been while using the Enzyme-Active Retinol Serum. I stopped Tretinoin and used the Enzyme-Active Retinol Serum for two nights and to my complete shock (by the speed and the difference in my skin), my skin went right back to being as smooth, hydrated, and dewy as it was pre-Tretinoin. I'm convinced - this is the ONLY retinol!

This serum is amazing! It does exactly what it says - brings you all the benefits of the retilnol, withoit any irritation.

I initially was deciding between this and Medik8 Christal Retinal. I decided to go with Protocol as the ingredients list was a lot shorter, which really appealed to me. I am really happy with my decision.

This serum is very lightweight, does not irritate, cause rednessnor any dryness at all. All you get is amazing glow, smoother skin and more even tone. It also helps with reducing the old acne scars and keeping blemishes at bay. And you don't need to wait long until you see results. I noticed a difference after 2 days!

I really hope this product will never be discontinued, as it is my holy grail!
