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.

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.

Holy Grail Vitamin C

I have exclusively been using this vitamin C for over a year now and it is my all-time favorite!! Pros: Ease of use (the pump feature lets you have waaay more control of the distribution of the product than the typical liquid serums); my skin feels nourished from the cream texture and skin barrier never feels compromised; it has definitely helped brighten up my complexion and lighten dark spots. No cons! Would highly highly recommend this product, especially if you are looking to try a vitamin c product for the first time.

Too Sensitizing

Like other ascorbic acid serums, this was sensitizing for me, the good thing about it is it's not as high maintenance as other vitamin c serums since it's stable/waterless. I was halfway through the bottle when I gave it up, it stung and had a warming sensation contributing to my redness, it wasn't worth it with little to no effect on my hyperpigmentation. I have tried the Vitamin C Serum from The Inkey List that has a waterless formula too which was more grainy and harder to blend, consistency-wise I prefer this one from Stratia.

Great product!

Most vitamin C products are too aggravating for my skin, but the Stratia C+C Serum is perfect! Leaves my skin feeling healthy and protected without irritation!

I purchased this to help with dark spots. I have sensitive skin and fortunately have not had any issues with this cream, but my dark spots have stuck around. I think the pump should be changed too. After a few uses it becomes harder to pump out. Overall, I really like Stratia and know that everyone’s skin reacts differently.

I’ve been really impressed with the results and I have noticed a significant improvement in the evenness of my skin. I took a star away due to the ‘feel’ of the product and the packaging. I really dislike the packaging. I’m not sure if I got a bad one, but the amount dispensed varied widely and the pump seems to catch. I’m not a huge fan of the silicon feel, but the upside of a stable formula is a trade-off I would take every time. I will definitely repurchase.
