LICORICE SERUM
Ref: 8883960101480
Brightening & Soothing: The presence of a high concentration of Glycyrrhiza Glabra (Licorice) Root Extract is well-known for its skin-brightening and anti-inflammatory properties. This, combined with ingredients like Portulaca Oleracea Extract, suggests a focus on calming and evening out skin tone.
PRODUCT INFORMATION
Skin Type
Suitable for Most Skin Types, Especially Uneven Tone and Sensitive Skin:
The water and glycerin base makes it generally suitable. Licorice extract is particularly beneficial for those with hyperpigmentation, dark spots, and uneven skin tone due to its ability to inhibit melanin production.
The soothing properties from licorice and Portulaca Oleracea Extract also make it suitable for sensitive or easily irritated skin. The inclusion of Sodium Hyaluronate adds hydration, which is beneficial for all skin types.

Incorporating the technique for optimal application
Here’s a refined guide:
- Cleanse – Wash your face with a gentle cleanser and pat dry.
- Apply – Dispense a few drops of the serum onto your fingertips.
- Spread & Press – Dab the serum onto 5–6 areas of your face and neck, then gently smooth it outward for intense hydration.
- Boost Absorption – Using your fingertips, perform quick tapping movements from the forehead to the cheeks, then from the chin to the neck. This enhances absorption into the skin.
- Absorb – Allow the serum to fully sink in before applying additional products.
- Follow Up – Apply a moisturizer and sunscreen (if used in the morning) to lock in hydration. If using makeup, this serum creates a smooth base for foundation.
For best results, use morning and evening for a hydrated, plumper, and radiant complexion.
