What You’ll Immediately Love About Daily C

Won’t Dry Out Your Skin
While many Vitamin C Serums are known to be harsh on the skin, Daily C leaves your skin feeling hydrated and cared for. Some of our customers even report they no longer need to follow up with their daily moisturizer.
Light and Smooth Texture
The formula spreads easily across the skin, without a sticky consistency. It’s so light, you won’t even feel it’s there. Of course, you’ll know it is because you’ll see (and hear about) the difference!
Absolutely No Funky Odours
Daily C excludes ingredients that give off an odour of smoked meat, hot dog water, or fermented fruit. On the contrary, our customers describe Daily C as having a pleasant, candle-like scent.
★★★★★
“When I first used dermtheory’s Vitamin C Serum, it immediately left my skin feeling smooth - even moisturized. There was no sticky left-over feeling like my previous Vitamin C Serum, and I could feel it absorb into my skin right away. Over time, it made my skin appear brighter and more hydrated. I loved how you only need a little bit of product to spread over the entire face.”
Resham E

Clean Ingredients You Can Count On

(and Easily Count).
Daily C is scientifically formulated with a high concentration of clean, potent active ingredients that are biologically compatible with the skin and are easily absorbed. So they help to protect your skin and restore its natural health.
There’s nothing fishy about our formula.
You’ll only find ingredients that benefit the skin or stabilize the formula. Nothing else. We’ve purposely kept our ingredient list short, so there’s more room for the active ingredients that actually work. 

All of the good stuff, none of the bad. An intelligent blend of natural and synthetic ingredients that function synergistically.

BRILLIANT PRODUCT, WELL WORTH EVERY PENNY!
I felt the difference as soon as I applied on my face. It fills the fine lines and wrinkles, and skin looks healthy, hydrating and glowing - The results are INSTANT. Working at Health Care / Beauty Product Store, I used numerous skincare and anti-aging product, but since using this, I never tried anything else. At age of 60+, I am getting lots of compliments every day regarding my skin and complexion. The bottle is beautiful and the pump works perfectly well so no product wasted. 100% Highly Recommended!

From the first time I applied this serum, I instantly noticed a difference. My skin has a glowing, dewy look that lasts all day. It doesn't leave an oily finish or interfere with my make-up routine. Within a couple weeks, I also noticed a more even-tone complexion. This serum is a must have in everyone's skincare routine! Highly recommend.
Hafsa
★★★★★
Easy to apply, each puff gives me the amount enough for my face and neck. The product is smooth and soft, non-stinging or irritant. I can apply in the evening and it is very stable in the morning with sunscreen. After almost 6 months of application, I can say that it helps to reduce the fine lines, brighten my face complexion and improve the tone. Recommend it to all my friends 👍👍

★★★★★
I really like this product because you don't need a lot, one or two pumps per use covers the full face. I noticed that sometimes I can even go without needing to use a moisturizer after. My skin tone is more even, I don't see sunspots on my skin. You need to use it consistently to notice results but definitely recommend this product. Also, there's a very mild scent, which is nice without being overpowering.

Amazing product! I noticed a reduction of fine lines in less than 1 month of use. It left my skin feeling really smooth and it smells great too. I absolutely love this product! I will definitely be coming back for more!
Neveen S
★★★★★
It was the first time I used a vitamin c serum so I didn't know what to expect. I'm in my thirties with combination skin. Upon first use, I loved the texture of the serum, felt like a light moisturizer, and the smell was divine, just like a candle. After a few weeks, I noticed brighter smoother skin. Some of my previous acne scars began to lighten as well. The brightness and plumpness of my skin have stayed. Would definitely recommend this product!

Overwhelmed with the number of antioxidant serums on the market?

We understand! There’s a lot out there to choose from, 
and so much confusion about what really works.
You’ll find medical-grade, clinically-tested serums with endless positive reviews……but their formulas aren’t clean and may contain harmful ingredients. 

You’ll find “all-natural” serums touted as potent and safe…….but they’ve never been clinically tested for efficacy or tolerability. Which means more money (and product) down the drain. And more time wasted as you anticipate results that never come. 

But both worlds do have something substantial to offer you. And we wanted to bring you the best of each.
A formula that’s proven to be effective and safe. A harmonious blend of clinical and clean

Because why were you ever forced to choose one over the other, for your skin? 

With Daily C, you don’t have to. You get high-quality, scientifically-backed active ingredients that are just as clean as they are potent. Formulated by committed professionals who understand the complexities of skin science and what your skin really needs to look and feel its best.

Other Doctors Stand by our Formula.

Finally a Vitamin C I can trust! As a physician, I know of the many benefits of adding Vitamin C to my skincare routine. However, I have had difficulty finding products with active ingredients high on the ingredient list, that are fragrant-free. This product checked off all the boxes. After using dermtheory for about 4 weeks, the texture of my skin was noticeably smoother, my pores appeared smaller and my hyperpigmentation less noticeable. I look forward to continuing to use this product and recommending it to my own patients.
