C+C Serum


An antioxidant powerhouse with 15% vitamin C in a feather-light, water-free formula.

Brighten, smooth, and firm your skin with a daily antioxidant boost. This powerful serum features 10% ascorbic acid (the pure form of vitamin C) plus 5% ascorbyl tetraisopalmitate (an oil-soluble vitamin C derivative). We added some CoQ10 for good measure and put it all in a water-free formula to protect these potent but fragile antioxidants.

Brighten up and smooth out with two types of vitamin C.

Rich Vitamin E oil is added to boost the antioxidant impact of this lightweight serum.

Ascorbic acid

Highly potent antioxidant that helps prevent premature aging by neutralizing free radicals caused by UV damage, pollution, and other sources.

Ascorbyl tetraisopalmitate

Oil-soluble derivative of vitamin C that penetrates skin deeply to fight free radicals, boost collagen production, and brighten skin tone.


Powerful antioxidant that’s found naturally in the skin. CoQ10 levels decrease with age, so skincare featuring this ingredient has anti-aging benefits.

How it works

Vitamin C is one of the most powerful skincare ingredients you can get without a prescription. It can:

• Scavenge and neutralize free radicals

•Increase collagen production

• Fade hyperpigmentation

However, the form of vitamin C that’s easiest for your skin to use, L-ascorbic acid, is also extremely unstable, breaking down quickly when exposed to water, heat, or light. That’s why most vitamin C serums turn orange and need to be replaced often.

C+C Serum uses 10% L-ascorbic acid, and to keep it safe, we’ve suspended it in a lightweight silicone formula away from water, heat, and light. That means it’s stable on your shelf for a full year. We also added 5% ascorbyl tetraisopalmitate, an oil-soluble form of vitamin C.

To up the ante, we added another incredibly powerful antioxidant, Coenzyme Q10 (otherwise known as ubiquinone) to make sure no free radical is left un-scavenged. Bisabolol, a key component of German chamomile, helps soothe and calm skin.

Put it all together and you’re left with an incredibly potent yet non-irritating antioxidant serum to help brighten, smooth, and firm your skin.

C+C Serum does not have a pH because it’s an anhydrous (water-free) product.

Is it right for me?

We chose C+C's vitamin C percentages to hit that sweet spot: effective but not irritating. That means it's perfect for even sensitive skin. Since C+C Serum's silicone base evaporates away, it's lightweight, non-greasy, and suitable for all skin types.

Due to the nature of C+C Serum’s silicone base, it’s important to apply the product to clean, dry skin and wait a few minutes before applying your next product. Layering other products without allowing C+C’s base to evaporate can cause pilling or balling of product.

All Stratia products are free of common irritants like fragrance, alcohol, and essential oils.

Lovely product

I like this product a lot. Most vitamin c serums irritate my skin - this one is super gentle and easy to use. I let it dry as recommended, and have never had an issue with pilling.

Not a fan

I received this from someone else who had a bad experience with it, and I'd have to agree. The silicone texture feels weird, and this product does not behave well with any of my other products.

3rd time purchase

After 2 bottles of C+C serum I want to provide an honest review. I started out with lots of acne marks on my cheeks at the end of last summer, now today those marks have faded. The serum is slippery due the silicones but it is the most gentle vitamin C I have used from high end to drug store. I will continue to use as long as Stratia makes it.

Peace of mind vitamin c

This product had a learning curve, as I have not used a silicone-based skincare product before. Once I waited a few minutes after applying and applying to dry skin, I really enjoyed this product. This product’s color does not change, as I was always apprehensive of liquid vitamin c’s that would be orange. This comes out in a white-ish cream color and I have seen my face get brighter after consistent use. I love the innovation of Stratia’s products and feel great that I can trust their products to have no fragrances or essential oils in their products ever. I recommend this vitamin c!

Why I Bought Stratia Vitamin C

The reason I bought this was because of a review on the site Beautypedia which is put out by Paulas’ Choice, a well know internet skin care line. She does lots of research on products, and when she gives something 5 stars I investigate the product further. I have been happy with the results.
