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.

This is good, but i cant say that Ive used it consistently enough to notice a difference. Still, it didn't break me out and felt really great on my skin! My only hang-up about it is the fact that you have to wait a few minutes after applying to let some of the ingredients evaporate. It just means that I have to wash my hands again since I do other stuff for those few minutes and dont want to reach into my skincare products with dirty hands again. Still, not bad

Favorite daily ritual

I haven’t properly started my day until I put this on in the morning. Has been a game changer for my skin ever since I started using it 3 years ago!

The c+c serum and all their other products are fantastic. My pores have shrunk, blackheads are less severe (and they were bad bad), and skin has a healthy glow. I would recommend this to anyone, I'm glad someone recommended it to me.

Love This Product - Not so much the pump

I've used this vitamin C superstar for years and I have a regular subscription so I always have it on hand. I have dry skin and this is the 3rd step of my morning routine every morning. It has a wonderful amount of Vitamin C in a solid bottle so sunlight can't get in. The only reason I can't give this a 5-star rating is that I've had 2 pumps in the last few months just not work! I've had to take off the cap and dig the product out and that does take away from the experience obviously. The one I'm currently using I just shake to the top so I can get out the product. If this could be addressed I would have given this 5 stars. Wonderful product.
