Please forward this error screen to 67. How to Pop a Pimple Using Science! Today we will be discussing hyaluronic acid’s benefits for skin, and why molecular weight is important! Product recommendations are at the bottom of this post. Alrighty, let’s get you up to speed on everything you need to know! Glycosaminoglycans are simply long unbranched carbohydrates, or sugars, called polysaccharides.
It gives your skin structure, is responsible for that plump-hydrated looking effect, plays a pivotal role in the wound healing process, and decreases as we age making us more susceptible to sagging and wrinkles. For starters, it can bind up to 1000 times its weight in water! That’s one of the main reasons it’s used in skincare — in other words, it functions as a humectant, and holds water molecules onto the surface of your skin to keep it nice and hydrated. Anytime we are talking about skin that is well moisturized, we’re mainly referring to skin that has a lot of water content. Perhaps you’ve heard of the term transepidermal water loss, or TEWL for short? This is the scientific term for the measurement of how much water is evaporated from skin. When a product prevents TEWL, that means it is keeping your skin hydrated by making sure that water doesn’t escape from its surface.
Hyaluronic acid does exactly that, i. Apart from being a very effective hydrator, a couple of studies have shown that it is very good for healing wounds! 11 patients with burn injuries applied 1. HA every day, and the study found it actually slowed down wound healing compared to just pure glycerin.
This may have been because of the concentration and molecular weight of hyaluronic acid. More about this in the next section! A study with 152 patients found that applying 0. In other words, it helped heal ulcers that had inflamed or compromised blood vessels. A similar study to the one above was conducted and found the same thing.
That is, silver sulfadiazine plus hyaluronic acid heals wounds a lot faster than silver sulfadiazine alone. So it turns out that not all hyaluronic acid is treated equal. There are some varieties that are a bit controversial, and increased levels of HA are actually linked to inflammatory skin diseases like psoriasis. What hyaluronic acid is beneficial for skin has to do with its molecular weight and concentration.
The molecular weight refers to its mass, or how big the HA molecule is. This is measured in something called unified atomic mass units, or dalton for short. This seems to be the sweet spot according to studies. Anything higher won’t do much good. Let’s break down the studies and you’ll see a pattern. A study on 15 subjects with rosacea found that applying 0.
