Defense C Serum

Senté Defense C Serum is a daily antioxidant serum that brightens, evens tone and refines texture while helping defend skin against UV and environmental damage. It pairs a stable, gentle form of vitamin C with Senté's patented HSA technology, so you get the glow of vitamin C without the irritation that often comes with it.

Key ingredients

• THD Ascorbate (Vitamin C): an oil-soluble, highly stable form of vitamin C that brightens and protects while being far gentler than L-ascorbic acid
• HSA (Heparan Sulfate Analog): Senté's patented technology that mimics a molecule naturally found in skin to support repair and renewal

Why we love it

• Brightens dullness and helps even out skin tone
• Antioxidant protection for your daily routine
• Formulated to minimize irritation, so it works for sensitive skin
• Pairs perfectly with your evening retinol and in-studio treatments

Best for

Dullness, uneven tone, early signs of aging, environmental and sun damage, and sensitive skin that can't tolerate traditional vitamin C.

How to use

Apply in the morning after cleansing, before moisturizer. Always follow with a broad-spectrum SPF 30 or higher. After peels, laser or microneedling, follow your esthetician's aftercare instructions before restarting.
