After a short hiatus, our beloved Ultra-C Brightening Serum is finally back! A small change in ingredient sources caused the formula to separate and texture to fall short of our standards. We listened closely to your feedback, researched extensively, and rigorously tested the serum until it was perfect.

The New Ultra-C Brightening Serum

The new formula combines 10% stabilized Vitamin C with our Herbalbright Complex™, creating a serum that brightens, protects, and revitalizes your skin. Vitamin C, extracted from citrus (and gently processed to remove the photosensitizing component) and vitamin E team up to support collagen production, while kojic acid and bearberry extract gently exfoliate and improve uneven skin tone. Prebiotic lemon peel bioferment brightens and keeps your skin microbiome balanced, and a pH of 5.4 protects your natural barrier.

Why We Love It:

Brightens hyperpigmentation, sun spots and dull areas
Smooths rough skin and reduces fine lines
Protects skin from environmental stressors
Supports healthy, balanced skin with gentle exfoliation

WHO BENEFITS?

SKIN TYPES: 3, 4, 5, 8

HOW TO USE

SKINCARE STEP 4: Treat
Perfect for morning* or night, the serum absorbs beautifully into the skin, giving you a radiant, luminous glow even in the depths of winter. Massage a few drops into clean skin and follow with your favorite moisturizer.

If you’ve been waiting for its return, we’re thrilled to welcome it back to your daily routine. And if this is your first time trying it, your skin is in for a real treat.

*Our stabilized vitamin C does not cause photosensitivity.

Whether you’re welcoming back a tried-and-true favorite or trying it for the first time, the Ultra-C Serum is your mid-winter glow secret.
