Will Cell Active irritate my skin?
No, Cell Active is formulated to deliver high-performance results while remaining suitable for sensitive and acne-prone skin. Cell Active uses dual-soluble Vitamin C system that allows for effective absorption without the harsh irritation often associated with traditional Vitamin C serums that uses L-Ascorbic Acid like Skinceuticals C E Ferulic and other dupes. And it uses dedicated barrier repair actives that prevents your skin from breakouts or stinging / redness.
What makes Cell Active different SkinCeuticals or other dupes like Timeless, Maelove or Sunday Riley CEO?
Cell Active uses two forms of Vitamin C — water-soluble and oil-soluble — so it works at the surface and reaches deeper layers where dark spots and collagen actually originate. It's made fresh in small batches to eliminate oxidation risk, and its 9 actives go beyond brightening to actively repair your skin barrier and support collagen production. AND its super safe for sensitive and acne prone skin.
Will this serum oxidize or turn orange over time?
NO. Two things cause Vitamin C serums to oxidize — air exposure and time. Cell Active solves both. The airless pump keeps air out with every press. Small-batch production cuts transit time down to days, not months. That's why it still smells and performs the way it should when it reaches you.
When will I start seeing results?
You may notice a brighter, more radiant glow within the first few uses. With consistent use:
14- 30 days: improved brightness and hydration
30-60 days: more even tone and increased radiance
60-90 days: visible improvement in firmness and fine lines
How does it smell?
Cell Active has a faint honeysuckle scent from the formula itself — no added fragrance, no synthetic smell. Just a clean, fresh serum that smells the way it should. And it doesn't react on sensitive or smell allergic skins
How to use it?
Wash your skin with a cleanser to thoroughly remove makeup, SPF, and impurities. Then apply Cell Active to clean, dry skin and gently press into the face, neck and hands. Then apply a richer moisturizer (Like Flora C) or just apply a SPF.
What if this doesn't work for my skin?
That's what the 30-day money-back guarantee is for. Try Cell Active for a full month, and if it doesn't deliver, you get every dollar back. No hoops, no questions.

The only Vitamin C serum that has made such a big difference. I'll 33 and the fine lines and skin texture changes started happening a couple of years ago. I tried a dozen if not more serums that did nothing, some even dried and irritated my skin. The first time I used Cell Active I knew this products was something special. Feels so good going on and my skin literally looks instantly bright after application. The best part though is after a few months of using it, my fine lines are GONE!! My skin texture is smoother and my skin overall looks brighter and rested. I look years younger.
Love this line and love Cell Active.
I am obsessed, if I could only use three words, those would be them! or maybe they would be "addicted to this", "glow all day", or so many others. This serum is like nothing I have ever tried, and having worked in the skincare industry, that is saying a lot. It it thick but not heavy, nourishing and hydrating, and truly makes my 45 year-old skin look ages younger. The pictures I am posting are after just one use (with the Flora-C day moisturizer as well) so you can see the dramatic effects after one wash/use. It gets better with time as well - all effects multiply. Skin looks dewy and fresh all day, pores are reduced, wrinkles appear diminished.
I bounce around from product to product, but since finding the Cell Active serum, I am loyal and simply cannot find anything else that performs this way. The bottle lasts quite awhile too. If you are hesitant, just give this a try - I think you will get hooked like I have.

Best regards,

I have very dry skin, and a lot of these types of products don't work well for me. That said, this stuff has been excellent. It keeps my skin soft all day. It's not oily or shiny either which is always a plus. The container is also thoughtfully designed and very easy to open and close, and there's no cap to lose.
Hey Ya’ll ~ I’ve used CELL ACTIVE for a few months now and look at my skin. The formulation does exactly what it says…activates cells! You can feel it working! I can’t wait to put this on my face & neck each morning! Not only does it deeply penetrate right away, it leaves a light vail of protection all day long. My skin is as smooth as silk with a glow of hydration. MAXDAHLIA is my #1 GO TO SKIN CARE! Love that it’s made in small batches and WOMAN OWNED💖FANTASTIC PRODUCTS!
Feels good on my skin, light. I have extremely oily skin, this moisterizes enough to keep it from over oiling itself.
