Glycerin is sort of presumably one of many oldest skincare components in existence. We’ve got documentation relationship again so far as the late eighteenth century exhibiting that it was used for hygiene. Likelihood is, should you choose up a private care product, you’ll see glycerin someplace on the ingredient checklist. Glycerin is such a staple within the magnificence business, however for a very long time, nobody gave it a second thought. It was drowned out by the hype about different hydrating components, regardless of being simply as efficient. Previously couple of years, I’ve seen glycerin getting extra recognition for the powerhouse that it’s. On this put up, 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 towards different hydrating components.
What’s Glycerin, and The place Does It Come From?
Glycerin, also called glycerol, is a fatty alcohol. Individuals are typically stunned by this due to the pervasive perception that alcohol in skincare is unhealthy. That is actually solely true of drying alcohols. The truth is, lots of the skincare components you recognize and love will be categorized as fatty alcohols! They excel at moisturizing, softening, and conditioning the pores and skin.
Glycerin is a byproduct of the oil business. When oil is extracted from one thing and processed, glycerin is left over. Traditionally, it was derived from additional animal fats and combined with wooden ash to create cleaning soap. So far as the beauty business goes, a overwhelming majority of glycerin now comes from plant-based sources. This may very well be something out of your primary 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 means.
How Does Glycerin Profit the Pores and skin?
Glycerin is included in a category of components often called humectants (you’re most likely already accustomed to 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 necessary 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 an entire host of different pores and skin points, together with effective traces, crepey or tough texture, and sensitivity.
The extra hydrated your pores and skin is, the extra mild will probably be capable of replicate. This implies humectants like glycerin may also 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 acceptable for all pores and skin varieties. It’s so innocuous that it may be used day by day (and even a number of occasions 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 when you get water into the pores and skin, it’s good to 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 great 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 Pores and skin Sorts 1-4) don’t want so as to add a lot oil and might use one thing mild. Mixture or dry pores and skin varieties (like Pores and skin Sorts 5-9) don’t produce as a lot oil on their very own, so that they’ll wish to attain for one thing richer.
The one time I might advise towards utilizing glycerin (or another humectant for that matter) is should you’re in a really dry atmosphere, like an airplane. Since there’s no water within the air for the glycerin to draw, you run the chance 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’ll 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 turn out to be comedogenic, and that is by no means the way it’s utilized in merchandise. Glycerin is definitely a terrific 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 the most effective hydrating, skin-plumping advantages from glycerin, flip to leave-on merchandise. This isn’t to say glycerin can’t be a terrific ingredient in rinse-off merchandise like cleansers. As I discussed, it might probably enhance the feel of a product and provides it moisturizing properties. But when your purpose is to enhance the water content material of your pores and skin and pull in as a lot moisture as doable, a leave-on product is the way in which to go. Strive reaching for a toner or a serum (I just like the Vitamin C&E Therapy or Pores and skin Drink Focus).
Moisturizers with glycerin may also be very useful. Many moisturizers will use a mixture of humectants, like glycerin, together with extra emollient components 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 incorrect, it’s a terrific ingredient! However this has additionally led to the misunderstanding that it’s far superior to different hydrating components. On the finish of the day, glycerin and hyaluronic acid each perform as humectants and have a really comparable impact on the pores and skin.
There are two fundamental upsides to glycerin—it’s a smaller molecule than hyaluronic acid, and it’s cheaper to formulate with. Smaller molecule measurement means it’s capable of penetrate extra deeply into the pores and skin, which is the place will probably be only. Hyaluronic acid will be chopped up into smaller molecule sizes as properly. However because it doesn’t begin out that means and desires 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 components (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 right down to advertising and marketing, finances, and client desire.
