Polyglutamic acid, discover the most sought-after active ingredient in beauty treatments today
It is the new fashionable ingredient in cosmetics because it has been proven that it is one of the best active ingredients for skin care. Until now, one of the top ones was hyaluronic acid which we have heard about ad nauseam, and continues to be a basic component in formulas that seek hydration, since it is suitable for all skin types, enhances the effect of other active ingredients, and above all, it is effective against signs of aging. .
He polyglutamic acid (PGA) arrives to take its place at number one in the active rankingeven with more power, since its moisturizing effect is up to four times greater than that of hyaluronic acid, createsing a film that hydrates and smoothes the skin, fading expression lines.
The dermatologists defend this new asset, they assuredo Its amino acid composition ensures good absorption, integration and permanence in the epidermis, thus prolonging the hydration effect. for much longer.
To know in detail everything this can offer acidit is interesting to know what its origin is. Is about a active ingredient from plant world with very high capacity for retain water at our fur, and thus increase its correct hydration and elasticity.
Skin care enthusiasts always looking for new active ingredients are increasingly turning to this new molecule with a powerful moisturizing power: polyglutamic acid. The pharmacist Belén Acero, owner of the Avenida América Pharmacy in Madrid and a specialist in dermopharmacy, tells us more about this new ingredient.
What is polyglutamic acid?
Polyglutamic acid is a natural active ingredient, derived from the fermentation of soybeans, which has moisturizing properties. We knew hyaluronic acid, capable of retaining almost 1000 times its weight in water, but with polyglutamic acid we managed to go further in hydrating the skin because it can retain and absorb up to 5000 times its weight in water. Above all, because its moisturizing power also comes from its ability to ‘trap’ water in the heart of the skin, says the pharmacist.
How does this new active ingredient act on the skin?
Low molecular weight polyglutamic acid improves water reserves by stimulating the production of hyaluronic acid and natural moisturizing factors, both with powerful long-lasting moisturizing effects. Therefore, this acid increases the skin’s natural hydration for deeply hydrated, plump and soft skin.
Polyglutamic acid is deposited on the skin creating a film that minimizes water evaporation. Therefore, it prevents transepidermal water loss and dehydration, which, by the way, leads to loss of luminosity and premature aging of the skin, while keeping water in the heart of the skin, strengthening the skin barrier.
Finally, unlike hyaluronic acid, polyglutamic acid is known for its ability to inhibit and reduce the action of an enzyme that ‘destroys’ the skin’s natural hyaluronic acid, hyaluronidase. Thus, the skin retains its hydration level over time.
What are the benefits of this ingredient on the skin?
Its use is recommended for all skin types, particularly aged and dehydrated skin, as well as all skin that needs an extra supply of hydration. In addition, it is able to soothe and accelerate wound healing and restore skin elasticity. And finally, it corrects the signs of aging, recovering the firmness of the skin.
Another interesting aspect to take into account is that polyglutamic acid does not interfere with other ingredients, being compatible with other active ingredients such as vitamin C, which also provides extra luminosity and protects it from free radicals. And of course, it can be combined with hyaluronic acid, so it can be included in both routine day creams and nighttime facial treatments.
