Paula's Choice Vitamin C Serum 25% with Glutathione — 1 oz, Fragrance-Free Brightening & Firming

Paula's Choice 25% Vitamin C Serum is a concentrated, fragrance-free facial serum that uses a stable 25% vitamin C blend plus glutathione and antioxidant technology to brighten discoloration, boost radiance, and help skin appear firmer without added irritation.

This clinical-strength serum combines oil- and water-soluble forms of vitamin C with glutathione and Paula’s Choice GAP technology to deliver antioxidant benefits and improve the look of uneven tone and texture. Designed for daily use under moisturizer and sunscreen, the formula focuses on delivering visible improvement in radiance and elasticity while minimizing potential irritation through an optimized antioxidant system.

How does this serum reduce discoloration and uneven tone?

The formula pairs a high concentration of vitamin C with glutathione and GAP technology to target areas of pigmentation and dullness. Vitamin C works to support cellular antioxidant defenses while glutathione helps brighten areas affected by sun and age-related discoloration.

• 25% vitamin C blend includes both oil- and water-soluble forms for layered penetration.
• Glutathione supports skin’s natural brightening processes.
• GAP technology helps recycle skin’s own vitamin C and E for ongoing benefit.

Will this serum feel irritating on sensitive or reactive skin?

Although this is a high-concentration vitamin C product, the inclusion of glutathione and GAP technology moderates potential irritation by supporting antioxidant balance. The formula is fragrance-free and crafted to deliver clinical-level results while limiting common irritants.

• Fragrance-free — reduces risk of scented irritants.
• Antioxidant system designed to improve tolerance.
• Use gradually (every other day) if you have very reactive skin, then increase frequency as tolerated.

How should I incorporate this serum into my skincare routine?

Apply a few drops to clean, dry skin once daily—preferably in the morning—followed by moisturizer and broad-spectrum sunscreen. For sensitive skin types, start by using the serum every other day and build to daily use as tolerance allows.

• Apply 1–2 pumps to face and neck after cleansing and before moisturizer.
• Layer under sunscreen for daytime antioxidant protection.
• Can be paired with a lightweight moisturizer; avoid mixing with very strong actives at first.

What visible improvements can I expect and when?

With consistent use, the serum aims to improve brightness, evenness of tone, and the appearance of firmness by supporting collagen-related pathways and antioxidant protection. Timing varies by individual, but many users notice increased radiance within weeks and continued improvement in texture and tone over months.

• Early: increased skin radiance and smoother texture.
• Ongoing: reduced appearance of discoloration and a firmer look.
• Best results with regular sunscreen use and continued application.

Who is this for: This serum is intended for people seeking a potent, science-backed vitamin C treatment to address uneven tone, dullness, and loss of firmness. It’s suitable for all skin types who want clinical-strength antioxidant benefits without added fragrance—those with sensitive skin should introduce it gradually. Ideal for anyone committed to a targeted daytime antioxidant step paired with SPF to protect and preserve results.
