Stratia C+C Vitamin C Serum – 15% Potent Formula with 10% L-Ascorbic Acid for Bright, Even-Toned Skin - Non-Irritating, Water-Free Antioxidant Face Cream, 1 Fl Oz

Love Stratia products generally. This product is no different. I use it as a first step it feels light weight, almost powdery, and dries down quickly. No smell at all, and no irritation. It helps keep my sunspots faded!

Background I previously used a highly rated, very popular vitamin C for about 1.5 years, so I have a clear baseline for how these typically perform. Application This is where it stands out. My previous vitamin C was hard to spread, so I ended up using more than necessary just to get full coverage. This one glides on effortlessly, spreads evenly, and immediately solves that issue. I use significantly less product. No drag, no sticky finish. Formula (Why It’s Different) This uses L-ascorbic acid (the active form of vitamin C) in a water-free formula, which is generally more stable and effective than many common versions. That likely explains the better spread and efficiency. Formula Feel Feels more refined than what I’ve used before. It layers cleanly with the rest of my routine and hasn’t caused any irritation. Results (So Far) Too early to evaluate dark spots or firmness, but the formulation and application both suggest a higher-performing product. Bottom Line Strong first impression. This fixes a real usability issue while offering a more advanced formula. I’ll update after a few weeks of consistent

I have dry sensitive skin with a few acne scars and comedones from months ago. I used this product for just two days and I already see major improvement on my acne. No tingling except in broken skin and absolutely no irritation. Trust me when I say this. My skin is sensitive even to some of the gentlest ingredients like centella and Niacinamide in high percentages. But l-ascorbic acid doesn't irritate me at all, especially this serum and Dr.Brenner. I love that this serum has both water soluble, as well as fat soluble antioxidants, giving you complete protection. This has 10% l-ascorbic acid, 5% THD, and 0.5% Q10. Not easy to formulate these three together. If you use water to dissolve l-ascorbic acid, it will make the product oxidize faster. If you use oil to dissolve THD, it may break you out. Using silicones is a genius move stabilizing all three ingredients, while also extending it's shelf life by a year, while leaving behind nothing but the ingredients on your skin after application. It also comes in an airless packaging, which further extends it's shelf life. It has no fragrance or denatured alcohol or essential oils, which is sensible. I also love the novel application of it. It goes on like a cream, but the silicones evaporate in few minutes, leaving behind nothing but the active ingredients. But you gotta give it few minutes before you go in with a moisturizer. People who are complaining about breakouts probably didn't wait for the silicones to evaporate. Love this product. Will definitely repurchase.

As other reviewers noted, this product does sting. I have been using just over 2 weeks. For the first week and a half or so, it would sting my skin slightly but now that my skin has gotten used it, there is no sting at all. The product consistency takes some getting used to because it is a silicone base and has very slippy feel. I use 1 pump in one hand and take half of the product and quickly spread to one half of my face with my other hand and then spread the rest of the product on the other half of my face and use any remaining product on my neck. Since I haven’t used it long term, my initial results so far are that my forehead texture is improving and over all redness in my skin is reducing and improving the brightness in my complexion. I am experiencing a small amount of skin purging and have had some spots appears on brow line but they are quickly healing. I do not have issues with hyperpigmentation or melasma, so I cannot comment on its effectiveness for treating these skin concerns.

at first I hateddddd the texture of this. it's very silicone-y but it's because there's no water in the formula and it's honestly probably for the best because it makes it more stable. and as much as I dislike the feel of it, this is the only vitamin c aside from the derma-e one that I feel like makes a difference to how my face looks. but you have to use it as it's written: the step immediately after washing and drying your face, then let it sit for a couple of minutes so the silicone-y texture goes away, then follow with the rest of your skincare routine. if you don't let it sit before putting stuff on top it *will* pill 100%, but this is when I usually brush my teeth and that's enough time for me. hateeee the sensory aspect of it, but it goes away if you use it the right way and it really is a great serum, so this will be a grumpy reorder once I run out lol

I really wanted to love this formula because it’s so stabilized at such a great price, but it broke me out so bad! For those that do not struggle with breakouts, this is a great product. If silicone is not your friend, this isn’t the product for you.

OBSESSED with this product! It feels like rubbing silk on your face and I love it. Its light weight and a little goes a long way

This was my first Stratia product. I bought this expecting not to see a huge difference. I tried the Mad Hippie Vit C and also Melano CC and never noticed much a difference. Stratia's is amazing! So easy to use, don't have to store it in the fridge, and doesn't burn too bad at all. It layers well under my tinted mineral sunscreen. After two weeks of daily use, I noticed such a huge difference in my skin. My pores look smaller, everything is smoother, redness is way more evened out, and overall my skin looks glowy! I use benzoyl peroxide 10% gel at night for acne, Stratia C+C two pumps every morning followed by 30spf Bliss Blockstar. I put my sunscreen on 30 min or so after the C serum and have never had an issue with pilling. My sunscreen goes on exactly the same as when I didnt use the serum. Definitely repurchasing this and I plan to check out other items from Stratia too. I love it!
