Cetaphil Vitamin C Face Serum 1 oz — Healthy Radiance Antioxidant-C, Brightens & Reduces Dark Spots for Sensitive Skin

Cetaphil Healthy Radiance Antioxidant-C Serum is a gentle, fragrance-free Vitamin C serum formulated to brighten skin and visibly reduce the look of dark spots and hyperpigmentation for sensitive skin.

This lightweight 1 oz serum combines a sensitive-skin friendly Vitamin C derivative with Cetaphil's GentleBright Complex to support a more even, luminous complexion without irritation. Designed to defend against surface free radicals and reduce the appearance of brown spots and post-acne marks, the formula is hypoallergenic, oil-free, paraben-free and non-comedogenic so it layers easily under moisturizers and sunscreen for daily use.

How does this serum help reduce dark spots and discoloration?

The serum blends an antioxidant-rich Vitamin C derivative with 2% niacinamide to target visible dark spots and uneven tone. Antioxidants help defend skin surface from environmental stressors while niacinamide helps fade the look of brown spots and supports skin barrier resilience.

• Concentrated antioxidant protection to counter surface free radicals
• 2% niacinamide in GentleBright Complex to even tone
• Formulated to address age spots, sun-related dark spots and post-acne marks

Is this serum suitable for sensitive or reactive skin?

Yes—the formula is created with sensitive skin in mind, using a gentle Vitamin C derivative and hypoallergenic ingredients to minimize irritation. It is fragrance-free, oil-free and non-comedogenic, reducing the chance of sensitivity while providing brightening benefits.

• Fragrance-free, paraben-free, and oil-free formulation
• Hypoallergenic and dermatologist recommended for sensitive skin
• Designed to defend against dryness, irritation, roughness, and tightness

How should I incorporate this serum into my skincare routine?

Use the serum once or twice daily after cleansing and before moisturizer and sunscreen. Apply a small amount to the face and neck, allow it to absorb, then follow with your usual hydrator and SPF in the morning to protect results from further UV-related discoloration.

• Apply to clean, dry skin morning and/or night
• Follow with moisturizer; always pair with sunscreen in daytime
• Suitable for layering under makeup due to lightweight, non-greasy texture

What should I expect and how long until results appear?

Visible improvements in radiance and a reduction in the appearance of dark spots typically develop with consistent use over several weeks. Because the formula is gentle, changes may be gradual; continued daily application helps maintain antioxidant defense and evened skin tone.

• Gradual brightening and improved overall radiance over weeks
• Consistent use helps diminish the look of hyperpigmentation
• Gentle support for a weakened barrier while improving texture

Who this is for: This serum is made for people with dull, uneven or spot-prone skin who need a mild but effective brightening product that respects sensitivity. It fits those who prefer fragrance-free, non-comedogenic skincare and want antioxidant protection plus niacinamide support to address dark spots and improve skin tone without aggressive actives.
