Hydrating Serum

50 ml — PGA + hyaluronic acid

Hydrating serum with PGA and hyaluronic acid for long-lasting skin hydration.

Hyaluronic acid hydrates deep within the skin, while PGA forms a protective layer on top. For double hydration, from within to the skin’s outermost layer.

Apply every morning and evening to your cleansed face and neck.

The serum is step 2 of the hydrating routine. Apply it before your cream.

Polyglutamic acid (PGA) — Forms a protective moisture barrier on the skin and locks in moisture. Protects hyaluronic acid from breaking down, keeping your skin hydrated and plump for longer.

Hyaluronic acid — 3 types of hyaluronic acid provide hydration in different layers of the skin:

  1. Major: immediate effect.
    Stays on the outermost layer of the skin, prevents moisture loss, and instantly softens the appearance of fine lines caused by dryness.
  2. Medium: longer-lasting action.
    Penetrates just below the surface and forms a moisture reservoir that keeps the skin hydrated for hours.
  3. Small: deep care.
    Penetrates deep into the skin and stimulates the production of hyaluronic acid, collagen, and elastin for long-term results.

Contains 0% fragrance. Suitable for sensitive skin, including during pregnancy.

FAQ

PGA stands for polyglutamic acid. It forms a protective moisture barrier on your skin and retains moisture on the surface.

In addition, PGA protects hyaluronic acid from breaking down. This keeps your skin hydrated and plump for longer.

The formula has become more powerful. While the previous serum used hyaluronic acid and glycerin, this serum combines hyaluronic acid with PGA.

The difference lies in how long the hydration lasts. PGA retains moisture on the surface and protects the hyaluronic acid, helping the hydration last longer.

Yes. A serum delivers active ingredients into your skin, while a cream seals them in and locks in moisture.

Therefore, apply your day or night cream after the serum. This way, you'll get the most out of both.

This serum is suitable for all skin types.

Dry skin gets the hydration it needs and feels more comfortable immediately after application.

It is also well tolerated by oily skin. The serum is water-based and oil-free, so it absorbs quickly without leaving a greasy film. Apply it to your entire face and neck.

You can feel and see the hydration immediately. After application, your skin feels softer and more comfortable, and fine lines caused by dryness are less noticeable.

For fuller, more supple skin, it is best to use the serum daily for several weeks.
