Remedy Science's Daily Defense is a fragrance-free 15% Vitamin C complex serum formulated to brighten skin, support the barrier, and protect against everyday environmental stressors.

This dermatologist-formulated serum blends stabilized Vitamin C with next‑generation antioxidants and barrier-supporting actives to help restore radiance and evenness. The lightweight formula is designed for daily use on face and neck, layered under sunscreen in the morning or used at night to complement your routine. It targets dullness and texture while incorporating ingredients chosen to neutralize free radicals and calm sensitized skin.

How will this serum fit into my morning routine?

Use a few drops on cleansed skin before moisturizer and sunscreen. The serum absorbs quickly and is formulated to layer well under other products, providing antioxidant defense throughout the day without added fragrance.

• Apply 3–4 drops to face and neck after cleansing and toning.
• Follow with a hydrating moisturizer for comfort and protection.
• Finish with broad-spectrum SPF for daytime antioxidant synergy.

What key ingredients make this different from other Vitamin C serums?

This formula pairs 15% stabilized Vitamin C complex with ferulic acid, ectoin, and targeted antioxidant enzymes. Those actives are combined with soothing Centella asiatica and barrier-supporting Bifida ferment lysate to balance protection with calm.

• Stabilized 15% Vitamin C complex for brightening and clarity.
• Ferulic acid and Superoxide Dismutase to boost antioxidant performance.
• Ectoin and Acetyl Zingerone to help skin handle daily stressors.

Is this safe for sensitive or reactive skin?

The fragrance-free formula was designed with comfort in mind and includes calming Centella asiatica and barrier-support ingredients to reduce irritation risk. Patch testing is advised for very reactive skin.

• No added fragrance and dermatologist-formulated by Dr. Shah.
• Bifida ferment lysate supports the skin’s natural barrier function.
• Start with every-other-day use if you have heightened sensitivity.

How quickly will I notice results and what should I expect?

Visible brightening and improved radiance can appear within weeks, while texture and tone improvements typically develop with regular use over several weeks to months. Results depend on individual skin and concurrent sun protection.

• Initial boost in radiance and evenness within 2–4 weeks for many users.
• Continued texture refinement and barrier support with consistent use.
• Best outcomes when combined with daily sunscreen and a balanced routine.
