*Free radicals have left the chat*

Discover a fresh approach to your morning ritual with this remarkably concentrated refining, brightening, and hydrating treatment. Suspended within a silky, light, hydrating gelée delivery system, our uniquely unconventional, ultra-potent antioxidant complex provides full-spectrum protection from environmental stressors while working to soften and blur the look of pores, spots, and texture.

Brighten + Correct

This advanced formula simultaneously shields skin while dynamic actives refine hyperpigmented spots, pores, and texture.

Antioxidants protect by neutralizing free radicals: unstable, reactive molecules that can accelerate cellular damage, causing visible effects in our skin. Vitamin C is a powerful antioxidant, but it is also renowned for its ability to restore firmness, promote a bright and even tone, and stimulate collagen synthesis. Two stable and bioavailable derivatives of vitamin C, sodium ascorbyl phosphate + ascorbyl glucoside, deliver this potent ingredient without the sting or irritation associated with traditional l-ascorbic acid. Not only great for sensitive types—this formula shines on congested, acne-prone skin as it combats visible breakouts without irritation.

Defend + Fortify

The antioxidant synergies of our unique blend are what make this innovative, multi-level defense system extraordinary.

White pine bark, sourced for its proanthocyanidins (OPC), boosts vitamin C‘s effectiveness, enhances photoprotection of sunscreen, and improves skin elasticity. Green coffee seed has smoothing, firming, and regenerating qualities thanks to its high concentration of chlorogenic acids (CGA). We complete the story with hero antioxidant superoxide dismutase (SOD), a talented enzyme that neutralizes damaging superoxide radicals while reducing visible redness and irritation in the skin.

C + OPC + CGA + SOD = the ultimate antioxidant alliance.

Refine + Hydrate

This complete transformative treatment effectively refines texture and tone for a smooth, clear, glass-skin appearance.

Sustainably derived prebiotic freshwater microalgae support wound healing for accelerated restoration of visible blemishes. The novel active yeast oligopeptide gently boosts cell turnover to retexturize and reveal the vibrant, glowing complexion beneath. The elegant polysaccharide of tremella mushroom adds intensive nutritive hydration with its soft, jelly-like texture. Hyaluronic acid, comforting allantoin, and barrier-boosting niacinamide join forces for sustained moisture balance and a dewy, plump finish.

Shield skin daily from multiple signs of cellular damage including fine lines, uneven tone, and loss of elasticity with this luscious, thirst-quenching, all-in-one serum.

Your daily shield from oxidative stress.

In the morning, apply a single pump to clean face, neck, and eye contour while skin is still damp. Gently massage to absorb. Follow with another moisturizing layer if desired, such as Beam Me Up, and a high protection factor sunscreen. May also be used at night. For best results, use at least once daily and limit sun exposure.


C-Shield is a low viscosity gelée emulsion with a deep brick-red hue that dissipates on application. It delivers active ingredients and hydration with a feather-light finish. Oily skins will likely enjoy C-Shield and SPF alone, where drier skins may like an emollient layer sandwiched between the two.


Spot test for sensitivity prior to first use. C-Shield should feel instantly hydrating on contact without any hint of 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.

    Excellent antioxidant serum, especially for morning use. Easy to layer under other products.

    Wow, was instantly intrigued by the ingredient list (actives right where you want to see them and plenty of calming/ hydrating extracts) and it has not disappointed! Could tell my skin was suffering due to stress and prolonged stints inside so was looking for a potent hit of antioxidants (hello, vit c!) to revive it. Have been using this every morning instead of my usual hydrating serum and it has definitely helped to refine my complexion and bring back its luminescence, excited to see what more good things are to come! I think this is a fantastic form of vitamin c and works wonders in this thoughtfully formulated serum. 🙂 (FYI it smells kind of smokey which i am in love with)

    Gentle serum works well with my sensitive skin. Use this in the morning and have not experienced any breakouts.
