Hydration revolution: formulator’s information to hyaluronic acid


Hyaluronic acid is likely one of the most in-demand beauty components right now. An extended-time favorite in skincare, hyaluronic acid is now marketed for its high-performance, hydrating properties in bodycare – and now even in haircare. It’s a darling of the cosmetics trade and wonder customers alike.

However it’s sported on so many beauty labels, you’d suppose it’s a new-found ingredient. In a technique it’s “new” as it’s produced very otherwise right now – as you’ll quickly uncover.

This superhero of hydration definitely deserves our consideration.

Why it’s so feted and what beauty advantages does it convey? Importantly, does it stay as much as the hype?

Right here, we unravel the secrets and techniques of hyaluronic acid – a powerhouse of hydration – wanting past its popularity to discover why it’s a game-changer for indie beauty formulators.

Spoiler alert: hyaluronic acid’s high-performance prospects are nicely inside attain of the brand new beauty formulator!

What’s hyaluronic acid?

Hydration revolution: formulator’s guide to hyaluronic acid
Hyaluronic acid is a polysaccharide discovered naturally within the pores and skin in its extra-cellular matrix, and can be a part of the pores and skin’s pure moisturising issue (NMF) together with different compounds corresponding to urea, lactic acid, fatty acids (ceramides). It due to this fact contributes to sustaining the pores and skin barrier.

The pores and skin holds round 50 p.c of our physique’s hyaluronic acid content material, so you’ll be able to sense already why it might have a key position to play in our pores and skin’s functioning.

Hyaluronic acid in cosmetics – its origins
Within the Nineteen Sixties, animal-sourced types of hyaluronic acid have been utilized in cosmetics. The most typical supply for each beauty and medical makes use of in that period was derived from rooster combs. Use of animal-derived hyaluronic acid has decreased over time as a result of moral considerations, potential allergenic reactions, and the event of extra sustainable and cruelty-free manufacturing strategies.

Immediately, hyaluronic acid is produced by way of bio-fermentation processes utilizing micro organism as a way to present moral and constant sources for the cosmetics trade. Nevertheless, do verify along with your provider about its origins.

How does hyaluronic acid hydrate our pores and skin?

How hyaluronic acid hydrates
Hyaluronic acid’s magic lies in its skill to carry as much as 1000 instances its weight in water, making it the last word hydrating hero. It is a superb humectant and in contrast to different hygroscopic beauty components, its skill to draw and maintain water is much less depending on the surroundings round us; which means it performs excellently no matter the extent of humidity.

A beauty humectant is a useful, hygroscopic ingredient that hydrates the pores and skin because of its skill to draw and bind to water. The water supply can range: humectants can appeal to water from the humidity within the surroundings round them, and even from the pores and skin itself by pulling water from deeper layers to extra superficial layers.

Different humectants frequent in pure cosmetics are glycerine, sorbitol (a sugar alcohol), honey, propanediol (pure model), sodium lactate, and hyaluronic acid. See our information:

The formulator’s information to pure humectants

However there’s a draw back. As we age, our pores and skin’s pure manufacturing of hyaluronic acid reduces and degradation of the hyaluronic acid additionally will increase, leading to pores and skin dryness and dehydration. Together with hyaluronic acid in formulations might help revitalise the pores and skin’s moisture ranges, resulting in a extra luminous, plump complexion.

First, we have to discover the types of hyaluronic acid – together with, surprisingly you may suppose, its molecular weight – as a way to perceive the way it works its magic in our formulations.

Molecular magic: low- vs high-weight

Low vs high molecular weigh hyaluronic acid
For formulators, the excellence between high and low molecular weight hyaluronic acid is essential to the artwork of formulating a super-hydrating beauty. On beauty ingredient provider websites, you might have seen low molecular weight (LMW-HA) and excessive molecular weight hyaluronic acid (HMW-HA) talked about and questioned what they have been.

Briefly, low molecular weight hyaluronic acid penetrates deeper into the pores and skin – staying on the epidermic degree – providing extra lasting hydration, whereas excessive molecular weight creates a topical, protecting barrier on the pores and skin’s floor providing short-term hydration and visual plumping of the pores and skin.

This dynamic duo of molecular weights ship each rapid and longer-term hydration, and you should use each in the identical formulation. There may be some debate concerning the effectiveness of utilizing both weight of hyaluronic acid in rinse-off haircare preparations, however some beauty corporations are offering proof of its hydrating powers even on this use.

We look at the molecular distinction in depth on our devoted “Mini-Lab” on hyaluronic acid over in our membership website, The Lab at Method Botanica. Register to be first to know when The Lab opens its doorways, so you’ll be able to benefit from the hyaluronic coaching module together with over 35 different in-depth subjects.

The way to formulate with hyaluronic acid

Now concerning the significance of its molecular weight, let’s take a look at the types of hyaluronic acid accessible to the beauty formulator.

INCI: Sodium hyaluronate

Hyaluronic powder: Yow will discover hyaluronic acid as a white powder or as a gel. We usually use hyaluronic acid between 0.01 and 1 p.c. You’ll need to hydrate the powder in water for some time (in a single day is good to make sure it’s totally dissolved).

Simply as we dissolve gums in glycerine, we will additionally decide to make use of glycerine as a wetting agent to assist make the hydration of hyaluronic powder simpler; or use emollients and humectants like propanediol for the job. There isn’t a purpose you’ll be able to’t mix humectants. Guarantee the burden of the diluent (water or glycerine) so you’ll be able to work out the maths so as to add the specified quantity of hyaluronic acid to your formulation.

  • Gel formulations: Keep in mind that low molecular weight hyaluronic acid gained’t type a gel.
  • pH vary: Hyaluronic acid is greatest used within the decrease pH ranges of round 5- 5.5.

1. Aloe Vera

INCI: Aloe Barbadensis Leaf Juice Powder

One of the in style components in skincare, aloe vera is a soothing and hydrating ingredient, with a water content material starting from 99 to 99.5%.
