I use the Cellex-C Advanced C Serum religiously now. My skin looked dull and a bit saggy, but after couple months its glowing and more even tone. A bit pricey for everyday but I make it last. Could be hard to find sometimes so I stock up.
I am loving my new skin after using the vitamin c serum. Hope to not have irritations later.
I started using Cellex-C because I wanted to add vitamin C to my routine without making things too complicated. My skin looks a little brighter now, and I like how fresh it feels in the morning. The only thing I’m not crazy about is how quickly the product seems to run out.
I tried Cellex-C because I wanted something focused on brightening and improving the appearance of uneven skin. It took some patience, but my skin eventually looked a little more even and refreshed. The formulas can feel quite active, so I think starting slowly is the safer approach.
Cellex-C has helped make my complexion look brighter and more even. The products feel like serious skincare, although I had to introduce the stronger formulas gradually.
The formulation is incredibly unstable. My bottle turned dark brown and oxidized within three weeks of opening, making it completely useless. It also smells heavily like stale metallic copper and left a yellow-orange stain on my skin that took two washes to get off.
The products feel pleasant and give my skin a nice boost of hydration. I noticed some improvement in brightness, but the overall results were fairly subtle for me.
The problem is how incredibly unstable it is. The formula oxidizes and turns dark orange way too fast, often before I’m even halfway through the bottle.
I’ve been using Cellex-C for several months and noticed my skin looking brighter and more even-toned. The results weren’t instant, but they became more noticeable with consistent use.
The vitamin C products helped brighten my complexion over time. Results were gradual but definitely noticeable.
It uses a very specific L-ascorbic acid formulation that genuinely tightens the skin and fades stubborn age spots faster than any trendy new serum I’ve tried. Yes, it tingles quite a bit on application, but the firming results speak for themselves.
Cellex-C serum noticeably brightened my complexion after consistent application. My skin feels smoother and looks more refreshed.
It has a completely fluid, amber texture that tightens skin tissue almost instantly upon drying. My skin looks noticeably firmer and much brighter after a solid month of application.
Cellex-C vitamin C products helped brighten my skin and fade some older acne marks over time. The formulas feel simple and effective, although they took a little patience before I noticed visible results.
The vitamin C complex really brightened my skin over time. It has a strong formula, so results are noticeable with consistent use.
I noticed my skin looked brighter after using the vitamin C serum for a few weeks. The texture felt slightly sticky at first though.
Been using the serum for a little over a month now. I do think my skin looks brighter, especially around my cheeks. The smell is a bit weird at first though and it can feel sticky if I use too much.
The Cellex-C Advanced C Serum is not the prettiest bottle on my shelf, but it actually did something. I used it every morning before moisturizer and my skin looked brighter after a few weeks. It did make me a little dry around the nose, so I had to stop pretending moisturizer was optional. Pricey, yes, but I respect a product that works without being flashy.
My skin looked brighter after a few weeks but I experienced mild dryness initially; needed to pair with a richer moisturizer.
The vitamin c serum made my face feel sore and dry after awhile. Am disappointed.
Their serum made my complexion look more balanced, and I love how easily it absorbs into my skin!
Finally found an anti-aging serum that’s perfect for sensitive skin.
Not recommended to people with sensitive skin.
I was excited to try this because of the vitamin C reputation, but after a few weeks my skin was red and itchy. I didn’t notice much brightening, and the serum got darker in the bottle pretty quickly.
No brightening after weeks. Slight stinging and sticky finish. Disappointed.
I appreciate that they were early pioneers of Vitamin C in skincare, and the Advanced-C Serum is strong—but it oxidized quickly and caused a bit of irritation on my skin. Results weren’t consistent, and the packaging could use a refresh. Science-driven, yes, but not quite elegant or gentle enough for daily use on my skin.
Made my face feel itchy and uncomfortable.
