8 Sodium PCA Benefits for Youthful, Hydrated, Plump Skin

Want a smoother texture? Then, try sodium PCA.

Or perhaps it’s more moisturiser you’re after?

Then Sodium PCA has you covered.

Or maybe it’s a cooling, quenching overnight treat to plump and restore your skin?

Yep, you guessed it, sodium PCA is all the way, baby.

A streamlined skincare routine is about substitution: one product can do the job of several.

And there is no better electrolyte cocktail for your skin.

What is Sodium PCA?

Technically, it is the sodium salt of pyrrolidone carboxylic acid, a naturally occurring amino acid known as Proline found in proteins.

It’s a tricky little number that often goes by many guises, including monosodium salt, sodium pyroglutamate, or DL-proline monosodium salt.

Whilst some of the sodium PCA used in skincare is synthetically created, it is primarily a natural ingredient derived from plants, fruits, and coconut oil.

Fermentation involves using sugars and starches to produce a plant-derived ingredient.

Here at the Naked Chemist, we use sodium PCA derived from soybean fermentation in our formulas, such as Quench ultra-hydrating water gel.

It has several roles in the personal care industry, depending on where it is extracted from:

• The sodium PCA that is extracted from vegetables and grasses is often used for its emollient properties in moisturisers
• It is extracted from coconut oil and is used for its emulsification properties
• Algae and Seaweed contain moderate levels of PCA, which is often used for its water-binding properties

Sodium PCA Versus Hyaluronic Acid

Hyaluronic acid is often used as an ingredient in many formulations due to its ability to pull moisture into skin tissues and lock it there.

In skin care, it works similarly: sodium salt makes the molecule water-soluble and an effective humectant, drawing water from the atmosphere to your skin and hair, offering hydration.

Sodium PCA and Hyaluronic acid are humectants, but the main difference is how well they can produce this effect.

It can hold up to roughly 250 times its weight in water, while Hyaluronic acid can hold up to 1000 times its weight.

For this reason, these two ingredients are often used in combination to improve a formula’s moisture-retaining properties.

Sodium PCA is 1.5 times more effective than Glycerin at drawing water to your skin.

7 Benefits of Sodium PCA

Those reasons alone explain why you shouldn’t think twice about incorporating this essential ingredient into your skincare routine to give your skin that added humectant boost.

Especially when you consider all of its beauty benefits, its resumé is so long that it’s hard to make it past the first page:

• a humectant
• a film former
• an important moisture booster
• a potent anti-inflammatory
• has important moisture-binding properties
• anti-ageing properties, it plumps, hydrates and smooths
• Sodium PCA also increases the permeability of certain ingredients into your skin

1. Very hydrating

It is hygroscopic, attracting water from the air and imparting a moist feeling to hair and skin.

A naturally occurring component of your skin, it makes up roughly 12% of the natural moisturising factor (NMF), which consists of several components, including Amino acids, Lactic acid, Lipids and Proteins.

Together with the lipids that are naturally present in your skin, the NMF components work to keep your skin’s surface healthy, supple, and hydrated,

And we know this skin-friendly humectant can effectively penetrate your skin’s outer protective layer, meaning you get good results with low concentrations of 1 to 2.5 per cent in skincare.

2. Extremely moisturising

It acts as a moisture magnet. This study (1) found that cosmetic preparations containing at least 2% PCA significantly improved participants’ dry, dehydrated skin.

3. Anti-ageing

Your skin naturally contains sodium PCA, but these levels drop significantly as you age.

Because it is incredibly water-absorbing and can hold several times its weight in water, it can reduce moisture loss through evaporation, keeping your skin hydrated and plump, making it look more youthful.

4. Barrier protecting

Sodium PCA is essential to your skin’s intracellular matrix, preventing skin cells from losing water and drying out whilst protecting your all-important barrier function.

It helps rebuild the intercellular glue that holds your skin cells together, likened to the mortar that holds bricks together.

It is created by breaking down the protein filaggrin within corneocytes, the dead skin cells that make up the outermost layer of your skin.

This prevents moisture loss and reduces the effects of bacterial overgrowth and allergens, a topic discussed in this article.

5. Relieves eczema

This dermatologic condition is characterised by inflammation of the skin, resulting in erythema, irritation, and scaling.

This pilot study (2) examined the role of anti‐inflammatories in alleviating the signs and symptoms of mild‐to‐moderate eczema and found that when it was used in combination with other barrier-repairing ingredients, it significantly improved inflammation, rough texture, dryness, itching, and the overall appearance of participants’ skin after just two weeks of continuous application.

Moreover, there was a 79% reduction in itching, and skin hydration increased by 44%.

6. It reduces inflammation

It is an excellent ingredient for protecting the delicate microflora that make up your acid mantle, reducing inflammation, and preventing surface irritation.

7. An effective hair treatment

It is often used in hair care products. It is known in the industry to enhance the appearance and feel of hair by increasing suppleness and sheen.

It is also thought to improve the appearance of hair that has been physically damaged or damaged by drying chemical treatments.

To conclude. The naked truth

As you can see, there are many skincare benefits of Sodium PCA; it is an excellent ingredient for your skin.

It will restore an impaired barrier, prevent premature ageing, help reduce inflammation and relieve conditions such as eczema. It can even help moisturise hair.

It is non-comedogenic and non-irritating to your eyes and skin.

This study (3) found no evidence of sensitivity or toxicity, even at concentrations of 50%.

If you have enjoyed reading about this fascinating humectant, Panthenol is another important skin-plumping humectant.

That will help to restore your youthful glow.
