A brightening ampoule built around sea buckthorn fruit extract. Lightweight, fast-absorbing, designed to layer easily under a moisturiser and SPF.

  • Sea buckthorn at the lead. Hippophae rhamnoides fruit extract sits at the top of the ingredient list. Drives the radiance work.
  • Niacinamide for tone. Targets dullness and uneven skin tone.
  • 3-O-Ethyl Ascorbic Acid. A stable vitamin C derivative paired with bioflavonoids.
  • Hydration base. Sodium hyaluronate and beta-glucan hold the formula moist rather than dry-feeling.
  • Daily-able. Light enough for everyday use under makeup.

How to use

Dispense 2 to 3 drops onto the palm and apply to the face. Pat gently into the skin until absorbed. Always wear sunscreen during the day.
