Review: Hylamide Vit C & Hyaluronic Boosters

DECIEM is an innovative skincare brand based in Canada, and they’re something of a wild card. Their website is split up into several sub-brands, covering everything from primers to hair care products. I placed my first order with them in May, and received my order really quickly, which was nice. Shipping was free, too, which was even nicer. What appeals to me about the DECIEM products is not only the cutting-edge tech (in fact, so cutting edge I don’t understand much of it) but the humane price point. The Hylamide boosters I ordered range from 22 to 36 euros, the vitamin c being the most expensive but still very reasonable. I’m excited to try more from this brand.

The packaging is simple and has a fresh, contemporary feel. This isn’t the kind of brand to push a heavy luxury aesthetic, nor are they concerned with that “all-natural” hippie stuff – this is all modern and clinical. The bottles are frosted glass, and come with a dropper which is standard for boosters as far as I know. Some people find droppers inconvenient, but I think they’re nice and make me feel like I’m doing an experiment or something. So what of the contents?


Hyaluronic acid (HA) is a powerful humectant capable of binding moisture to the skin. It’s often used in dermal fillers since it has a plumping effect. This formula contains different types of HA as well as some fermented ingredients, which is interesting. The texture is pretty standard for HA boosters so it’s rather thick and syrupy – it’s made of sugars after all. You can either apply it alone or, as I like to use it – mixed with moisturizer. You only need a drop or two.

I don’t have dry skin to begin with so I use this as more of a preventative measure, but I do find my skin soft and plump after using it for a while. What Hylamide likes to advertise is that their HA booster is low-molecular – it’s been “chopped up” so to speak, meaning it supposedly penetrates deeper than conventional HA. And it does hydrate well – but I don’t know that any other HA booster wouldn’t do the same. The point is, this is a very affordable and sophisticated alternative to other hydrating boosters, and I would definitely buy it again.

Price: 22 EUR
Size: 30ml / 1 fl oz
Pros: Very competitively priced, hydrating. Easy to use.
Cons: The formula is interesting, but I can’t guarantee that it’s that different from other HAs.
Repurchase? Yes.


The Vitamin C booster is more exciting – it’s a highly concentrated serum booster with 25% ethyl-ascorbic acid, which claims to smooth and brighten your complexion. I bought it because I have some post-acne dark spots that I’d like to blast off my face, and I knew Vitamin C was a popular remedy.

This booster is a radiant success. I’ve been using it for a month or so, and I really find that my skin is more luminous and even than before. The pigment spots on my cheeks are vastly improved (hilariously, I got new ones from other acne breakouts. I’m working on those now.) so I’m officially a fan of this product. Like all good Vitamin C products, it smells a little odd, but I don’t mind it at all. Skincare isn’t perfume. The texture is very liquidy, so be careful when you’re using it – Like the HA booster, you can use it on its own or added to a different product. I pour 2-3 drops into the palm of my hand, then add my serum and mix before patting it into my face. Don’t try to apply it with your fingertips because it’ll just drip off.

Price: 36 EUR
Size: 30ml / 1 fl oz
Pros: Effective, Affordable, Sophisticated, Straightforward.
Cons: Funky smell, Texture makes it easy to spill.
Repurchase? Absolutely!!
