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

Paula's Choice 25% Vitamin C Serum is a clinical-strength, fragrance-free facial serum that uses a highly stable vitamin C complex plus glutathione and antioxidant technology to brighten discoloration, improve tone, and support firmer-looking skin.

This concentrated 1 oz serum combines oil- and water-soluble forms of vitamin C with glutathione and Paula’s proprietary GAP technology to deliver potent antioxidant protection while minimizing irritation. Formulated for all skin types, it targets visible discoloration, uneven tone and loss of elasticity without unnecessary fragrance or harsh additives. The formula slowly releases active ingredients to help skin appear more radiant and resilient over time.

How does this serum help reduce dark spots and uneven tone?

The blend of high-concentration vitamin C and glutathione works at multiple levels to address visible discoloration and promote a more even complexion. Antioxidants help combat free-radical damage that can contribute to dark spots, while supportive technologies help skin reuse its own vitamins for sustained benefit.

• 25% vitamin C combination of oil- and water-soluble forms for balanced delivery
• Glutathione to complement brightening and antioxidant activity
• GAP technology supports recycling of vitamin C and E in the skin
• Fragrance-free formula to reduce potential irritation

Will this serum cause irritation or sensitivity?

Although concentrated, this serum is formulated to minimize irritation by pairing vitamin C with glutathione and GAP technology, which help stabilize and temper activity. Users with very reactive skin should patch test first or introduce the product gradually to assess tolerance.

• Stabilized vitamin C reduces rapid oxidative breakdown
• Glutathione and GAP technology help buffer activity for gentler results
• Fragrance-free and clinically minded formulation to limit unnecessary irritants
• Start with every-other-day application if you have sensitive skin

How should I incorporate this serum into my skincare routine?

Apply to clean, dry skin once daily, ideally in the morning to pair antioxidant benefits with daytime sun exposure protection. Follow with a moisturizer and broad-spectrum sunscreen; at night, use it under your regular treatments to support skin repair and renewal.

• Cleanse and pat skin dry before applying 2–3 drops of serum
• Use morning for antioxidant daytime benefits; always follow with SPF
• Can be layered under moisturizers and treatments compatible with vitamin C
• Adjust frequency based on skin tolerance—gradual build-up recommended

What visible improvements can I expect and when?

Results vary by individual, but consistent use typically leads to improved radiance, more even tone, and a firmer-looking texture over weeks. The serum’s pro-collagen support and antioxidant actions aim to enhance elasticity while helping reduce the appearance of discoloration over time.

• Brighter-looking skin and reduced dullness with regular use
• Noticeable improvement in uneven tone and discoloration over weeks
• Support for firmer appearance through pro-collagen ingredients
• Ongoing antioxidant protection helps maintain improvements

Who is this for: Paula's Choice 25% Vitamin C Serum is designed for anyone seeking a potent, science-driven antioxidant serum to target discoloration, dullness and loss of firmness—suitable for most skin types when introduced gradually. It’s ideal for people who prefer fragrance-free, clinical formulations and want a high-concentration vitamin C option that pairs well with daily sunscreen and a targeted skincare regimen.
