Glycerin is sort of presumably one of many oldest skincare substances in existence. Now we have documentation of it getting used for hygiene relationship again so far as the late sixteenth century. Likelihood is, if you happen to choose up a private care product, you’ll see glycerin someplace on the ingredient checklist. Glycerin is such a magnificence staple, however for a very long time, nobody gave it a second thought. It was drowned out by the hype over different hydrating substances 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 publish, I’ll break down the historical past of glycerin, why it’s so useful in 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, also referred to as glycerol, is a fatty alcohol. Persons are generally stunned by this due to the pervasive perception that alcohol in skincare is dangerous. That is actually solely true of drying alcohols. Actually, lots of the skincare substances 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 blended 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 was 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.
How Does Glycerin Profit the Pores and skin?
Glycerin is included in a category of substances generally known as humectants (you’re in all probability already acquainted with hyaluronic acid, the preferred humectant). This implies it attracts water molecules like a magnet to extend water content material within the pores and skin. That is an extremely essential 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 superb strains, crepey or tough texture, and sensitivity.
The extra hydrated your pores and skin is, the higher it will likely be capable of replicate gentle. This implies humectants like glycerin may also assist pores and skin seem extra glowy.
In smaller percentages, glycerin will 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, considerable, and cheap.
Who Can Use Glycerin?
Along with being efficient, glycerin is a really innocuous ingredient. This implies virtually anybody can use it, and it’s additionally acceptable for all pores and skin sorts. It’s so light that it may be used day-after-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 sorts 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 want oils to create a barrier that retains that water in. This implies it’s important that you just apply a moisturizer after utilizing a humectant like glycerin. Naturally oilier pores and skin sorts (like Pores and skin Varieties 1-4) don’t want so as to add a lot oil, however mixture or dry pores and skin sorts (like Pores and skin Varieties 5-9) will wish to attain for one thing a little bit richer.
BTW, consuming water received’t hydrate your pores and skin (however these three issues will).
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 setting, like an airplane. Since there’s no water within the air for the glycerin to draw, you run the chance of it pulling water away from the deeper layers of your pores and skin as a substitute.
Will Glycerin Make Me Break Out?
Since glycerin is derived from oil, some individuals are involved it is going to clog their pores or trigger them to interrupt out. This isn’t the case—you would need to apply it at a focus of virtually 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 an amazing 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 amazing ingredient in rinse-off merchandise like cleansers. As I discussed, it may possibly 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 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 Remedy or Pores and skin Drink Focus).
Moisturizers with glycerin will 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 Towards Hyaluronic Acid?
It’s simple to be seduced by the massive quantity of PR hyaluronic acid has gotten through the years—and don’t get me flawed, it’s an amazing ingredient! However this has additionally led to the misunderstanding that it’s superior to different hydrating substances. 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 most important upsides of glycerin—it’s a smaller molecule than hyaluronic acid, and it’s inexpensive to formulate with. Smaller molecule measurement means it’s capable of penetrate extra deeply into the pores and skin, which is the place it will likely be only. Hyaluronic acid will be chopped up into smaller molecule sizes as effectively. However because it doesn’t begin out that means and wishes extra processing, you’ll normally 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 may 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, price, and client choice.
