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

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.

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.

Helps skin stay smooth and helps with dark spots.

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.

i love this product! it has a really nice velvety smooth finish. definitely be aware that it’s a high concentration of actives and can be irritating. i have sensitive skin but i built up to this using a 10% vitamin c first, worked really well! no complaints, good product and good value

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.
