Brightening and dark-spot care
Tranexamic acid, alpha-arbutin, niacinamide and vitamin C derivatives help improve the appearance of pigmentation, dark spots, post-blemish marks and uneven-looking tone over time.
Barrier-supporting hydration
Panthenol, ceramide NP, beta-glucan, allantoin and sodium hyaluronate help keep skin feeling calm, hydrated and comfortable while your routine focuses on brightness.
Healthy-looking glow
Niacinamide, glutathione and antioxidant-rich botanical extracts help revive tired-looking skin, while lightweight hydration leaves the complexion looking smoother and more luminous.
Texture
A lightweight serum that absorbs comfortably and layers well under moisturiser and SPF. The finish is fresh, hydrated and radiant without feeling heavy or sticky.
How to use
Apply after cleansing and toning. Smooth 1–2 pumps or a few drops over the face and neck, focusing on areas of dullness, dark spots or uneven tone.
Follow with moisturiser. Use morning and evening, and always finish with SPF during the day to help protect against further pigmentation and dullness.
If your skin is sensitive or new to brightening serums, start 2–3 times per week and increase gradually.
Skin type
Best suited for dull, uneven, pigmentation-prone, post-blemish-mark-prone, dehydrated, tired-looking, normal, combination and dry skin.
Sensitive skin should patch test first and introduce gradually, especially if already using vitamin C, exfoliating acids or retinoids.
