01. microsponge® delivery ascorbic acid

A multifunctional delivery system designed to provide sustained release, improve stability, and reduce the irritation of vitamin C in its clinically proven, pure form: ascorbic acid. Microsponge® is a patented technology where sensitive actives are loaded inside porous microspheres. These particles enhance results by continuously delivering a controlled dose of vitamin C throughout the day. This time-release effect mitigates sensations of itching and sensitivity while the sponge-like structure balances excess oil production. Expect skin to appear brighter, smoother, and more even without the sting of traditional ascorbic acid treatments.

Microsponge® is a registered trademark of AMCOL International Corp.

02. refining + brightening complex

This next-generation vitamin C serum exploits synergistic brightening and refining actives with a higher capacity for performance during UV-exposed hours. Two incredibly potent tyrosinase inhibitors, 4-butylresorcinol and glutathione, dramatically speed pigmentation-correcting effects of vitamin C. Touted as a complexion bioptimizer, diglucosyl gallic acid is activated by the enzymatic activity of our skin. It acts on seven biological targets to correct the look of discolorations and redness. Amino acid derivative ection brightens by blocking the formation of pigmented spots before they appear. In addition, german chamomile gently improves the appearance of acne for an incredibly brilliant, harmonious glow like never before.

03. antioxidant shield

Our brightening actives were not only chosen for their tone-correction benefits, but for their proactive antioxidant qualities as well. Both ection and diglucosyl gallic acid are exceptional photoprotectors, meaning they guard cells from UV-induced damage and prevent new hyperpigmented marks from appearing. In addition, vitamin C derivative ascorbyl tetraisopalmitate mirrors the potent antioxidant effects of ascorbic acid. We complete the story with hero superoxide dismutase, a talented enzyme that neutralizes damaging superoxide radicals while reducing visible redness.

04. instant + extended hydration

Instantly quench skin’s thirst and give a plumped, soothed, hydrated appearance that lasts all day. The elegant polysaccharide snow mushroom adds nutritive hydration with its soft, jelly-like texture. Functioning as an anti-dehydration shield, our xylitylglucoside complex helps optimize skin’s water reserves by boosting hyaluronic acid in the skin. Glycerin, the humble yet incredibly effective humectant, cooperatively hydrates and supports barrier function. Finally, calming madecassoside, smoothing palmitoyl tripeptide-38, and balancing prebiotic microalgae finish things off with a comprehensively restore healthful balance.

01.0 The Ritual

In the morning, apply 2 pumps to clean face, neck, and eye contour. Gently massage to absorb.

Follow with another moisturizing layer if desired, such as Beam Me Up or Night Shift, and broad spectrum sunscreen. To speed brightening effects C-Shield may also be used at night. For best results, use at least once daily and limit sun exposure.

03.0 Storage

This highly active formula is sensitive to light and heat. Store in a cool, dark place away from sources of light. A closed drawer or cabinet is best, not an open countertop or shelf. Use within 6 months.

If you live in a warm climate where indoor temperatures are above 23°C (73°F), consider storing in a refrigerator.

02.0 Texture

C-Shield is a milky, water-rich serum with a plumping skin finish. Its plush texture immediately delivers refreshing hydration and active ingredients without weight. As an ancillary benefit, microsponge® encapsulation technology controls excess oil throughout the day without drying the skin. Oily skins will likely enjoy C-Shield and SPF alone, where drier skins may like an emollient layer sandwiched between the two.

02.1 Notes

Spot test for sensitivity prior to first use. C-Shield should feel hydrating on contact without the stinging sensation commonly associated with vitamin C serums. Discontinue use if irritation occurs. C-Shield is considered safe for pregnancy and breastfeeding. Consult your health care professional to discuss your unique situation.
