I have been using this product in conjunction with the Hydra 5 B Complex for years. It is a daily must for me in my facial regime. I use three drops on my entire face, so it goes a long way. It makes my skin glow!

When I use 2 months, it make my face brighens. No tightening of the face has been found so far. But i still love it because it really can make my face brighens.

This product helped with the lines on my face, but it made my sensitive skin burn. I needed to quit using it.

Years ago, I was told by a top derm that if women used Cellex C , they wouldn't need laser resurfacing . I started using it on the spot, and he is right! I have significant sun damage to dry skin, and the change in my skin appearance is very notable. The texture, luminosity and fine lines are significantly improved. I have been using this product for years, and will continue. I am 70, and am told I look to be in my 50s

This serum is amazing. I use it every morning after washing my face and before toning, and I really have seen a difference in my tone and texture. Worth every penny!

I orginally started using this just because of the vitamin C to reduce the damage of free radicals, but I now use it on my neck also as I can see and feel the difference when I do. Beats buying another expensive cream target just for necks.

I started using this CellexC serum 25 years ago after having a facial at a local highly regarded spa. My skin was slightly oily, but very sensitive. My skin at 65 it is now much drier, but still finicky. I have tried many Vitamin C serums over the years, usually trying to find something less expensive or that has more hype, but I always cones back to this one. The ingredients are simple and it has zinc to calm my skin, AND it works. I’ve played tennis and golf over the years and had a lot of sun exposure, albeit with sunscreen, and my skin looks 10-20 years younger than most of my peers. If you are looking for a simple, non-irritating , and effective serum, look no further.

I tanned way too much without SPF when i was younger and the results are dark spots and fine lines, Cellex-c serum has made a real improvement in my dark spots my skin looks more even toned brighter, even my fine lines look less noticeable.

I have used this product for over a year and love how it helps my skin tone. It is a non-oily serum.

This is such a simple serum, but it works. It's not filled with a hundred different ingredients, just a handful that does the job. It brightens and tightens my skin, and it just makes me look overall better, fresher, more healthy. It's easy to work into any routine and it's as light as water, so it absorbs into your skin right away. It's great for all skin types too.
