★★★★★
Works even better than Skinceuticals and at half the price, will definitely be buying again. After a year of bouncing between vitamin C serums, I've found the holy grail. So happy with the results.

SO glad I found this product! I've used Skinceuticals Ferulic and C Serum for years, even had a friend that could get me a discount...regardless I prefer this superstar Vitamin C from Protocol. I did my comparative research, and the why's behind their products and packaging are spot on. My skin has never looked better and it's a third the retail cost of what I had been using.

Game changer. I've used vitamin c serum only once before this and it truly ruined my skin. Two years of correcting it later, I tried Protocol's vitamin c after being VERY happy with their retinol, and I'm amazed at how it changed my skin. With the retinol, my skin stayed clear from breakouts, but adding this vitamin c made my skin GLOW. Really, if you're using retinol, you should add in the vitamin c. But not just any vitamin c—Protocol is the only one I trust!

I'm 3.5 weeks into using the SMOL kit, and I can already see my skin transforming. My pores are smaller, my complexion is brighter, and my skin hasn’t looked this good since I was getting regular facials before my wedding. The retinol is gentle yet effective—no irritation or dryness. The Vitamin C serum is the first I’ve used that delivers real results, unlike Skinceuticals, which broke me out. The moisturizer is a nighttime game-changer, leaving my skin plump and hydrated. Overall, this routine has simplified my skincare and exceeded my expectations!

Try it. You won't be sorry. I love this serum. After no more than a week of using it in the AM, I was getting compliments on how fresh my skin looked. I have gotten better results with Protocol than I ever did with Skinceuticals, and it is half the price and doesn't smell like hotdogs! The packaging is strange and takes getting used to, but it prevents oxidation—so overall a win. I will not be without this serum!

I'm a serum junkie, a hoarder, a tester. The only Vitamin C serum that gave me a lifting effect! I have tried medical grade serums, Skinceuticals, pretty much everything under the sun. After daily usage, you'll notice that the skin feels toned, almost as if you had a procedure done.

It's a YES I will 100% be reordering this product from Protocol. I've tried many vitamin C serums from various brands in the skincare industry, and this is the winner for me. The best of all worlds—quality, price, effectiveness...10 out of 5 stars

★★★★★
I've tried a good number of Vit C serums, and this is by far my favorite. It smells good, the packaging can't be beaten in terms of freshness, and it gives my skin a plumpness (not oily or slick) that looks youthful. Each pump dispenses enough for face, neck, and upper chest. There are cheaper products out there, but this one is a relative bargain for what you get in terms of results.

★★★★★
I've been on a long journey to find a vitamin c that doesn't break me out. I mean EVERY ONE I try causes me to break out along my chin. Because I know how important this is for my skin, I'm constantly trying to find the one that is right for me, and THIS IS IT! Truly amazing product!
