Update 11/5/2019: So as many in the beauty community may know, the problematic owner of Deciem was pushed out and passed away in early 2019. In light of this, I’ve relaxed my decision not to support the company, though I have not returned to using any of the products I’ve reviewed previously.
Update: Since writing this review, I have decided I no longer wish to support Deciem or any of its brands. See here to see what products I like instead.
I mentioned yesterday that I’ve used Deciem’s Hylamide Booster C25 for a while now and that I’d post a review soon. Since it’s not an involved review, I thought I’d just do a quickie here on a Saturday. I don’t have a lot to say about it. I like it and I’ve repurchased it for when I run out, but I’m not asking a lot of it.
First of all, I think I should say a bit about why I use Vitamin C serum. A lot of people are looking for heavy duty anti-aging or brightening function from their Vitamin C serum. If that were my goal, I would certainly go for a proper L-Ascorbic Acid serum with Ferulic and Vitamin E for stability. Personally, a use Vitamin C in the mornings to give my skin a bit of an antioxidant boost and help my sunscreen along. Any brightening is purely icing on the cake.
So. This serum. This is a very light, watery-textured serum. It feels like a dry oil going onto the skin. It smells chemical-y, but not overwhelmingly so, with a slight hint of something fresh. It’s not fragrance, so they must just use a slightly fruity smelling solvent. It’s not unpleasant, though I have gotten used to it. I use 4 drops on clean, patted-dry skin in the morning. I let it sit for as long as I have to let it sink in, and then apply hydrating layers and sunscreen. It dries down quickly and leaves my skin feeling like skin so I don’t feel like I’m really layering a bunch of gunk on my face, which is how I like it in the morning (at night, however, gunk me up!).
And… that’s really about it. I mean, the main thing I’ve noticed is that it doesn’t break me out or irritate me. I’ve maybe seen a bit of lessening of the residual spots and pigmentation on my chin, but I have heavier-hitters in my routine that are more noticeable. But C25 is pretty consistent in my routine and I don’t care to see what happens if I remove it. It’s $33 for a 1-oz. bottle and I’m a bit more than halfway through it after 3 months of daily use. And I really use this every day unless I literally don’t get out of bed. And even then, if I get up for 5 minutes to make a cup of tea because Fiancé has abandoned me on my sickbed, I’ll swipe with some micellar water and pop into the vanity room to slap a little of this on. It’s that easy and makes me feel infinitesimally more human.
So that’s my review. Yes, there are ingredients with better research associated with them, but I like that I don’t have to keep this in the fridge or anything. It’s not exciting but it’s not going anywhere from my vanity any time soon.
NB: I purchased this product myself and was provided no incentive to review it.
