Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.

Humectant, Skin Conditioning, Skin Protecting

Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.

A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.

As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.

Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.

Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.

In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.

This ingredient is organic, colorless, odorless, and non-toxic.

Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

I got a sample of this and saw that it was FA safe and had no comedogenic or irritating ingredients so I tried it out. Only used it 4 times, but it was pretty obvious what a powerful humectant beta-glucan is. Just pure hydration and calm. Definitely buying the full size if I need the extra hydration. In this regard, it beats the skin1004 madagascar centella ampoule! (Still love that for beneficial Show more

Very hydrating, my must have product
Wow. I regret not buying this earlier. It's a somewhat thick serum that's very moisturizing and absorbs nicely into the skin,depending how much you use. I go heavy on this and put a full dropper on my face and it takes a while but it does sink in.

It has helped with my rosacea flareups and dry patches.

It's niacinamide free so it's a great hydrating Show more

I bought this when my skin barrier was damaged, hoping it would calm the irritation i have, but it made things worse. This serum broke me out badly. I think it might be due to the high concentration of ceramides, but it also contains PHA, so I’m not sure if it was a breakout or purging. However, when I stopped using it, my skin returned to normal. As a barrier serum, I don’t think this is Show more

I have very sensitive skin, and find finding products that work for me near impossible. Soothing on my skin, and i have noticed a huge difference in my textured, dry, sensitive and irritated skin (along side with other products i use)
