StratiaC+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

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 someone with sensitive skin, this product is amazing. There's no scent, it glides onto your skin like silk, and a little goes a long way. You're left with smooth and moisturized skin immediately after use. Typically I can't tolerate vitamin C, but this one has become one of my favorites. Great quality for the price.

Love this product. I can tell a noticeable difference after using it for a few weeks.

This vitamin C is formulated without water, making it shelf stable for much longer than most vitamin C serums. It will lighten sunspots and protect from future damage when used daily. However, the things that make it so stable also make it a hassle to use. The formulation requires application to perfectly dry skin and then a waiting period of around 5 minutes for the base to evaporate out, leaving the vitamin c behind. For me, this waiting period added to the waiting period required for sunscreen (sunscreen also needs about 5 minutes of time after application to form a film) felt too long for a normal morning routine.Other positives: very affordable for such a stable, effective product; lightened a dark spot that other serums haven't been as effective on; has no scentOne other negative: sometimes this product tingles/burns on application

If you have oily/combo skin and struggle with finding an l-asorbic acid that isn’t tacky and shiny, this is for you. I think all skin types can benefit for this as you can layer anything with this with no issues. You have to use it on a cleansed and dried face then let it settle for a few minutes before moving on to the next step. This resolves a lot of issues with vitamin c - it’s stable, easy to use, not sticky/shiny/oily, and has a bunch of added ingredients for antioxidant and brightening. It’s perfect!

I really like the feel of this serum on my face, not sticky. Leaves my face feeling smooth. After a couple of weeks I do believe my skin is brighter and has improved texture.

I'm not really sure how to feel about this serum. I have seen some improvement...but in all honesty, I am 48 and wasn't really using anything for my skin before I started using Stratia C+C. I figure I should see at least some improvement with the use of any product compared to nothing; right? After an entire month of use, I have seen and felt my skin become much softer but have not seen any changes in hyperpigmentation issues, blemish fighting, or firming. Achieving a 1 out of 4 claims is not a great track record imo. Many people will not necessarily like the smell of this product either. I don't mind it at all though. It's very earthy.

Switched to this from skinceuticals ce ferulic acid and am much more happy with it. Amazing product!
