Paula's Choice BOOST C15 Super Booster 15% Vitamin C Serum — Fragrance-Free, Antioxidant-Rich Brightening Booster (0.67 fl oz)

This lightweight, fast-absorbing booster blends pure vitamin C with supporting antioxidants to target dullness and uneven coloration while minimizing irritation. The formula combines clinically recognized antioxidants that stabilize vitamin C and support its performance, creating a potent daily step that can be used alone or mixed with moisturizers and serums to amplify glow and tone.

How quickly will I notice brighter skin?

Many users report a visible lift in surface radiance within minutes due to the serum's light-reflecting and smoothing action; more measurable improvements in discoloration and texture typically appear with consistent use over weeks. Results depend on skin condition and routine consistency, and pairing with sunscreen is essential for long-term benefits.

• Immediate boost: smoother, more luminous appearance within 15–30 minutes for many users
• Short term: improved glow and softer texture after several uses
• Long term: gradual reduction in uneven tone with regular application over weeks

What makes this 15% vitamin C different from other serums?

This formula uses 15% pure L-ascorbic acid—the gold-standard form of vitamin C—paired with ferulic acid and vitamin E analogs to increase stability and antioxidant synergy. A stabilizer antioxidant (ergothioneine) helps protect the actives from oxidation, so the serum stays effective while remaining gentle enough for many skin types.

• High-concentration L-ascorbic acid for potent brightening
• Ferulic acid and vitamin E work together to support antioxidant protection
• Ergothioneine enhances antioxidant performance and helps maintain product stability

How should I use the BOOST C15 Super Booster in my routine?

Use a few drops on clean, dry skin in the morning or evening, applied before heavier creams. It can be layered under moisturizer or mixed with other treatments; always follow with sunscreen in the morning to protect newly brightened skin.

• Apply 2–4 drops to face and neck after cleansing and toning
• Allow absorption before adding heavier serums or creams
• Use daily in the morning with SPF, or in the evening as tolerated

Is this suitable for sensitive or reactive skin?

The formulation aims to balance potency with tolerance: it’s fragrance-free and includes antioxidants to help reduce oxidative stress. People with sensitive or reactive skin should patch-test first and introduce the booster gradually, starting every other day to monitor tolerance.

• Fragrance-free formula reduces risk of irritation from added scents
• Start slowly—every other day—if you have sensitive skin
• Cease use and consult a professional if persistent irritation develops

Who is this for? Paula's Choice BOOST C15 Super Booster is designed for anyone seeking a targeted antioxidant step to brighten dull skin, fade uneven tone, and enhance overall radiance. It suits users who want a powerful vitamin C option that can be layered into existing routines—especially those who prioritize fragrance-free, stabilized antioxidant combinations. Ideal for morning use under sunscreen, it works for a range of skin types when introduced carefully.
