C-Reserve Serum

Regular price $160.00

A daily morning lotion built around 15% pure vitamin C, ferulic acid, vitamin E, and a proprietary blend of DNA repair enzymes. The C Reserve neutralizes the free radicals generated by UVA, UVB, infrared radiation, and ozone pollution — and goes one step further, helping the skin repair the cellular damage already in motion. The clinical reserve that your skin draws on every day, before sunscreen.


Best for

This is the daily AM lotion for skin doing real environmental work — sun, screens, infrared, ozone, urban pollution — and for the skin that needs more than antioxidant defense. The 15% vitamin C concentration delivers visible anti-aging benefits: more even tone, smoother texture, and a measurable reduction in the appearance of photodamage with consistent use.

The proprietary DNA repair enzyme system is the differentiator. Most antioxidant serums neutralize new free radical activity. This formula does that, and also supports the skin's own repair of cellular damage already accumulated. Defense plus repair, in a single morning step.

Particularly indicated for patients on GLP-1 medications, where rapid weight loss meaningfully increases systemic oxidative stress. The skin shows it first. The C Reserve was placed in this line to give that skin a higher daily antioxidant ceiling than a standard vitamin C product can deliver.

Recommended for all skin types. AM only, before sunscreen.

Key ingredients

15% Tetrahexyldecyl Ascorbate, a stable, lipid-soluble form of vitamin C that penetrates the skin barrier efficiently to neutralize free radicals, support collagen synthesis, and visibly even tone

Ferulic Acid, plant-derived antioxidant that stabilizes vitamin C and vitamin E and extends their photoprotective activity — clinically shown to amplify free radical defense against UVA, UVB, infrared, and ozone exposure

Tocopherol (Vitamin E), lipid-phase antioxidant that works synergistically with vitamin C to protect cell membranes from oxidative damage and reinforce barrier integrity

Proprietary DNA Repair Enzymes (Micrococcus Lysate, Plankton Extract, Arabidopsis Thaliana Extract), photolyase and endonuclease-based enzyme blend that supports the skin's own repair of UV-induced cellular damage already in progress

Sodium Hyaluronate + Squalane, hydration and barrier lipids that keep the skin comfortable, supple, and primed for sunscreen layering — never tacky, never heavy

How to use

Apply a pea-sized amount once daily in the morning to clean skin, using upward strokes across the full face, neck, ears, chest, and hairline. Layer under moisturizer and sunscreen—the two work as a system. Use consistently for visible improvements in tone and texture.

Why Dr. Linkner loves it

Sunscreen is necessary but insufficient—it blocks some UV but not infrared or visible light. Add a topical antioxidant like C Reserve (vitamin C + DNA repair enzymes) as your second line of defense. It neutralizes free radicals sunscreen misses, absorbs quickly, layers cleanly, and with consistent use delivers visible improvements in tone and texture. Especially important during GLP-1 use when oxidative stress is elevated, but valuable for anyone targeting photodamage.
