Imagine an invisible moisture shield for your skin. An ingredient that not only hydrates but also forms a protective film to lock it in, providing an instantly smooth and silky surface. This is polyglutamic acid, also known as PGA. It is a hydration superstar and a close relative to the more well-known hyaluronic acid.
Polyglutamic acid is a large molecule formed during the fermentation of soybeans. Due to its size, it primarily works on the skin's surface. There, it acts as a powerful moisture magnet, attracting and binding large amounts of water. The result is skin that feels deeply hydrated, plump, and dewy all day long.
Benefits of Polyglutamic Acid
Polyglutamic acid has quickly become a favorite for anyone seeking maximum hydration. It is known for its ability to provide an immediate plumping effect and a soft, smooth feel. Here are its key benefits:
- Provides immediate and intense hydration: PGA is one of the most powerful humectants available. It forms a hydrating film on the skin that provides an instant feeling of comfort and plumpness.
- Locks moisture into the skin: The film created by PGA acts as a protective seal. It prevents the moisture in your skin from evaporating during the day, providing longer-lasting hydration.
- Improves skin elasticity: When the skin is optimally hydrated, its suppleness and elasticity improve. Fine lines become less visible, and the skin takes on a more youthful appearance.
- Boosts your hyaluronic acid: A unique benefit is that PGA can help protect the skin's own hyaluronic acid from breaking down. This makes it perform exceptionally well in combination with products containing hyaluronic acid.
Skin Types and Uses
Polyglutamic acid is an excellent choice for all skin types, but it is a true hero for dry, surface dry, or dehydrated skin thirsting for moisture. It is also perfect for anyone wanting an extra smooth and hydrated base under makeup.
- For dry or surface dry skin that feels tight and lacks moisture.
- To instantly plump the skin and reduce the appearance of fine lines.
- To provide a dewy radiance to tired and dull skin.
- As a moisture booster in your routine, especially during dry winter months.
How to use Polyglutamic Acid
It is easy to include this hydration hero in your routine. It is gentle and straightforward. Here are our best tips:
- Application: Most commonly found in serums. Apply a few drops to cleansed skin. You can advantageously apply it to slightly damp skin to give it extra water to bind.
- Frequency: It is so gentle that it can be used every day, both morning and evening.
- Timing: Use it after cleansing but before your regular moisturizer. The moisturizer helps to seal in PGA and its hydrating effects.
- Combine with: PGA is an excellent team player. It works with all other ingredients. It is especially effective when used together with hyaluronic acid for a dual hydration effect.
