Glycerin is kind of probably one of many oldest skincare substances in existence. We’ve got documentation courting again so far as the late eighteenth century. displaying that it was used for hygiene. Chances are high, if you happen to decide up a private care product, you’ll see glycerin someplace on the inci checklist. Glycerin is such a staple within the magnificence trade, however for a very long time, nobody gave it a second thought. It was drowned out by the hype about different hydrating substances, regardless of being simply as efficient. Previously couple of years, I’ve observed glycerin getting extra recognition for the powerhouse that it’s. On this publish, I’ll break down the historical past of glycerin, why it’s so useful to your pores and skin, and the way it stacks up in opposition to different hydrating substances.
What’s Glycerin, and The place Does It Come From?
Glycerin, often known as glycerol, is a fatty alcohol. Persons are generally stunned by this due to the pervasive perception that alcohol in skincare is unhealthy. That is actually solely true of drying alcohols. In truth, most of the skincare substances you already know and love may be categorised as fatty alcohols! They excel at moisturizing, softening, and conditioning the pores and skin.
Glycerin is a byproduct of the oil trade. When oil is extracted from one thing and processed, glycerin is left over. Traditionally, it was derived from further animal fats and blended with wooden ash to create cleaning soap. So far as the beauty trade goes, a overwhelming majority of glycerin now comes from plant-based sources. This might be something out of your fundamental corn, soy, or flax to one thing extra unique, like Karanja weed. If it may be changed into oil, it may be a supply of glycerin. On the finish of the day, one supply of glycerin isn’t superior to the opposite since you find yourself with the identical chemical compound both method.
How Does Glycerin Profit the Pores and skin?
Glycerin is included in a category of substances often known as humectants (you’re most likely already conversant in hyaluronic acid, the proverbial celebrity of humectants). This implies it attracts water molecules like a magnet to extend water content material within the pores and skin. That is an extremely vital perform as a result of it helps stop dehydrated pores and skin (to not be confused with dry pores and skin). Dehydration can segue into a complete host of different pores and skin points, together with tremendous strains, crepey or tough texture, and sensitivity.
The extra hydrated your pores and skin is, the extra mild it is going to be capable of mirror. This implies humectants like glycerin can even assist pores and skin seem extra glowy.
In smaller percentages, glycerin may also be used as a stabilizer or to enhance the feel of a product. Chemists love this ingredient as a result of it’s efficient, plentiful, and cheap.
Who Can Use Glycerin?
Along with being efficient, glycerin is a really mild ingredient. This implies virtually anybody can use it, and it’s additionally applicable for all pores and skin varieties. It’s so innocuous that it may be used each day (and even a number of instances a day).
No matter whether or not your pores and skin is oily or dry, ALL pores and skin varieties want water. Our pores and skin cells can’t survive with out water! The important thing right here is that after you get water into the pores and skin, you could create a barrier that retains that water in. This barrier is created with lipids (aka oils), and it’s the place your pores and skin’s moisture barrier comes into play—it retains the nice in and the unhealthy out. Due to this, it’s important that you just apply a moisturizer after utilizing a humectant like glycerin. Naturally oilier pores and skin varieties (like Skin Types 1-4) don’t want so as to add a lot oil and may use one thing mild. Mixture or dry pores and skin varieties (like Skin Types 5-9) don’t produce as a lot oil on their very own, in order that they’ll need to attain for one thing richer.
The one time I’d advise in opposition to utilizing glycerin (or every other humectant for that matter) is if you happen to’re in a really dry surroundings, like an airplane. Since there’s no water within the air for the glycerin to draw, you run the danger of it pulling water out of the deeper layers of your pores and skin as a substitute.
BTW, ingesting water received’t hydrate your pores and skin (however these three issues will).
Will Glycerin Make Me Break Out?
Since glycerin is derived from oil, some persons are involved it should clog their pores or trigger them to interrupt out. This isn’t the case—you would need to apply it at a focus of just about 100% for it to develop into comedogenic, and that is by no means the way it’s utilized in merchandise. Glycerin is definitely an incredible ingredient for breakout-prone pores and skin as a result of it may be added to acne-focused formulation to make them much less drying.
To Get the Pores and skin Advantages of Glycerin, What Sorts of Merchandise Ought to I Use?
To get all one of the best hydrating, skin-plumping advantages from glycerin, flip to leave-on merchandise. This isn’t to say glycerin can’t be an incredible ingredient in rinse-off merchandise like cleansers. As I discussed, it may well enhance the feel of a product and provides it moisturizing properties. But when your aim is to enhance the water content material of your pores and skin and pull in as a lot moisture as potential, a leave-on product is the best way to go. Strive reaching for a toner or a serum (I just like the Vitamin C&E Treatment or Skin Drink Concentrate).
Moisturizers with glycerin may also be very useful. Many moisturizers will use a mixture of humectants, like glycerin, together with extra emollient substances to provide the full spectrum of moisturization.

How Does Glycerin Stack Up In opposition to Hyaluronic Acid?
It’s straightforward to be seduced by the massive quantity of PR hyaluronic acid has gotten over time—and don’t get me improper, it’s an incredible ingredient! However this has additionally led to the misperception that it’s far superior to different hydrating substances. On the finish of the day, glycerin and hyaluronic acid each perform as humectants and have a really related impact on the pores and skin.
There are two essential upsides to glycerin—it’s a smaller molecule than hyaluronic acid, and it’s cheaper to formulate with. Smaller molecule dimension means it’s capable of penetrate extra deeply into the pores and skin, which is the place it is going to be handiest. Hyaluronic acid may be chopped up into smaller molecule sizes as nicely. However because it doesn’t begin out that method and wishes extra processing, you’ll often find yourself paying extra for a hyaluronic acid serum that has a number of weights of hyaluronic acid.
One other distinction between the 2 substances (and the place hyaluronic acid has the higher hand), is texture. Increased-end, well-formulated hyaluronic acid tends to have a silkier texture than glycerin, which might really feel a bit sticky or cheesy earlier than it dries down.
On the finish of the day, it actually comes all the way down to advertising, funds, and client desire.
