When exposed to water, Pure Vitamin C can degrade causing it to lose its effectiveness. A water-free formula (like Powerful-Strength Line-Reducing Concentrate) helps keep high concentrations of Pure Vitamin C stable and effective.

HOW VITAMIN C WORKS ON SKIN

AGING SKIN

Aging Skin

Over time and with daily oxidative exposure, skin develops deep lines and wrinkles, uneven skin texture, and dullness.

+ VITAMIN C

Vitamin C

Pure Vitamin C
(L-Ascorbic Acid)

is absorbed into skin and starts working immediately upon contact.

+ Vitamin Cg
(Ascorbyl Glucoside)

activates once absorbed into the upper layers of skin – forming L-Ascorbic Acid – to boost Vitamin C activity over time.

HEALTHY SKIN

Healthy Skin

Lines and wrinkles are visibly diminished. Radiance is improved. Skin texture is noticeably smoothed.

Vitamin C also acts as an antioxidant, helping to prevent future signs of aging.1,2

HOW HYALURONIC ACID WORKS ON SKIN

Hyaluronic Acid

With its ability to hold up to 1000 times its weight in water1, Hyaluronic Acid acts like a sponge by drawing moisture in to skin’s surface layers and expanding as it absorbs to plump lines and refine skin texture.

Why “Fragmented”?

Data demonstrates that a shorter length hyaluronic acid is better able to penetrate surface layers of skin.2 This allows more moisture to be drawn into the epidermis, causing increased line plumping and texture smoothing efficacy.
