PRODUCT INFORMATION
Skin Type
Suitable for Most Skin Types, Especially Dull and
Normal to Oily Skin:
The hydrating base is generally suitable. Grapefruit
extract’s brightening and potentially oil-controlling properties can benefit
dull and normal to oily skin types. However, those with very sensitive skin
should patch-test due to the citrus extract, which can sometimes be
irritating.

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.
