    I first used this under my moisturizer every night (I never use Vitamin C in the AM) for 3 months straight, and after that it was more on/off, in between trying out other products. Not in any of...

    I purchased this serum on Black Friday of 2019. It was on sale and I wanted to try the ingredient Ethylated L-Asorbic Acid. It is more stable than l-asorbic acid ,so I was hoping to get a longer...

    I have been using this on/off for around a year. It is one of the least cosmetically elegant formulas I have tried due to the tacky layer it creates on the skin. It feels like silicone and grease...

    Edit 2 (July 2020): This has been reformulated since my 1st review. It looks slicker now, but it actually feels less oily upon application and continues to absorb very well. I am still wearing it...

    In February I introduced Vitamin C into my routine in the morning to help brighten my complexion and fade my pigmentation from acne in the past. The first one I used was the Clique Fresh Pressed...

    I am surprised that this has such a low rating. I tried Vitamin C products from Timeless, Body shop and Ole Henriksen before trying this one. I like that this one feels quite a bit more oily, makes...

    I've tried plenty of vitamin c serums such as Timeless, Paula's Choice, Ole Henriksen, Caudalie, and OST. Some of the vitamin c serums have given me visible results, this one by Hylamide hasn't. I...

    I can't really think of any redeeming qualities to Deciem Hylamide C25. Granted, this is only the second C serum I've used, the other being Paula's Choice C15 Super Booster. I actually really liked...

    Im surprised at the lackluster reviews. I have incredibly oily skin and this is the only Vitamin c serum that doesn't make it oilier. Ive tried MANY Vit C serums and this is my top pick. I get...

    I bought this at the rec of the Skincare board for dull, lifeless skin. So far i like it, however it does go quickly if you use it twice a day as directed, so it can get expensive. Also i don't...

    Like many other reviews here, I can't tell if its working since the liquid remains clear and never goes yellow. Also, the difference isn't that big. I like the concentration however I'm used to...

    Not sure if this is working. My skin looks exactly the same - no change in my hyperpigmentation but perhaps the antioxidants are helping with free radicals and preventing aging. Not sure. Price...

    I don't know if I would repurchase this or not. I have not noticed any difference in my skin over the 2 months I've been using this, but I'm mostly hoping for preventative results. No idea if it's...

    I'm actually on the fence with repurchase. I was hoping for a replacement for my skinceuticals phloretin, and it seemed to fit the bill..at first. Over time my skin became very dried and irritated...
