Helps promote a brighter, more even-looking complexion and supports skin affected by dullness.

Five Types of Ceramides
Help strengthen the skin’s moisture barrier and protect against dryness.

Four Types of Hyaluronic Acid

CICA — Centella Asiatica Extract
Known for its soothing and skin-conditioning properties.

Liposome technology

Retinol, vitamin C derivative, vitamin E, ceramides, and exosome ingredients are formulated using liposome technology. This helps distribute the ingredients evenly across the outer layers of the skin while supporting hydration and a smooth finish.

Moisturizing all-in-one formula

The combination of hyaluronic acid, ceramides, and moisturizing oils helps replenish both moisture and lipids. The serum can be incorporated into a full skincare routine or used as a simple all-in-one treatment when the skin needs concentrated hydration.

How to use

After cleansing, take an appropriate amount and gently apply it to the face or areas of concern.

For first-time users:

1. Begin with a small amount, 2–3 times per week.

2. Apply in the evening before moisturizer.

3. Gradually increase use depending on how your skin responds.

4. Use sunscreen during the daytime.

The serum may also be applied at the final stage of your skincare routine when additional moisture is needed.
