PRODUCT DETAILS

Hello, glow. This hybrid serum pairs an immediate visible tone-up with brightening and wrinkle care in the same formula. Immediate, natural-looking tone correction gives uneven-looking skin a more balanced appearance, while its care focus also includes the look of blemish marks.

Its moisturizing milk-serum texture applies in a thin, smooth layer. Once applied, it leaves skin looking sleek, luminous and hydrated, with a dewy finish.

The serum is listed for all skin types. Its ingredient declaration includes fragrance, a useful detail if that is part of how you choose your skincare.

Key Ingredients

Fine dry pressed striations with soft amber, celadon, lavender and coral tones fade into a warm ivory matte surface.

Glutathione

A reduced tripeptide used as a cosmetic reducing agent. Small topical studies test specific concentrations and complete regimens—not every formula that lists GLUTATHIONE.

Niacinamide

Helps visibly brighten uneven tone and support the skin barrier.

Translucent ivory sculptural folds with glossy highlights and small clear droplets on a warm cream studio surface.

Alpha-Arbutin

A defined hydroquinone glucoside with emerging formula-specific evidence for more even-looking tone—not the same ingredient as Arbutin or hydroquinone.

Panthenol

Pro-vitamin B5 that helps skin hold moisture and feel softer and more comfortable.

Frosted serum bottle standing upright against softly folded white fabric.
