Neutrogena Collagen Bank Vitamin C Serum 15% — Fragrance-Free 0.5 fl oz, Micro-Peptides & 2% PHA for Brighter, Plumper Skin

Neutrogena Collagen Bank 15% Vitamin C Serum is a fragrance-free, high-potency topical serum formulated with 15% pure vitamin C, micro-peptides, and 2% PHA to help improve uneven tone and support visibly plumper-looking skin on face and neck.

This lightweight serum combines a concentrated dose of vitamin C with patented micro-peptide delivery and a gentle PHA exfoliant to target signs of aging and uneven skin tone. Designed to layer under makeup and daily SPF, the formula is non-comedogenic, allergy-tested, and free of dyes, parabens, sulfates, phthalates, and fragrance. Use it as part of a multi-step routine to enhance brightness and the appearance of firmness.

How does this serum brighten dull or uneven skin tone?

The serum delivers 15% pure vitamin C, a well-known antioxidant for brightening appearance. Vitamin C helps reduce the look of discoloration and dullness when applied consistently, while the added 2% PHA gently exfoliates to reveal smoother surface texture without harsh irritation.

• 15% pure vitamin C concentration for visible brightening
• 2% PHA to assist exfoliation and smoother skin tone
• Fast-absorbing liquid that layers under makeup and SPF

What role do micro-peptides play in supporting collagen appearance?

Patented micro-peptide technology in this formula is engineered at a smaller molecular size to reach deeper surface layers than larger peptides. These micro-peptides aim to support the skin’s existing collagen network visually, helping skin appear plumper and more resilient when used consistently.

• Micro-peptides designed to penetrate multiple surface layers
• Optimized delivery intended to support visible plumping
• Formulated to integrate with other collagen-supporting products

Is this serum suitable for sensitive or acne-prone skin?

The fragrance-free, non-comedogenic formulation is allergy-tested and dermatologist-tested to reduce the risk of irritation and breakouts. Its gentle PHA exfoliant is selected to provide mild surface renewal while being more tolerant for many skin types compared with stronger acids.

• Fragrance-free and free of dyes, parabens, sulfates, and phthalates
• Non-comedogenic to minimize pore-clogging concerns
• 2% PHA for gentler exfoliation suitable for many sensitive skin routines

How do I add this serum into my daily routine for best results?

Apply the serum to cleansed face and neck, avoiding the eye area, then follow with a broad-spectrum sunscreen each morning. For a targeted collagen-boosting regimen, pair this serum with Neutrogena Collagen Bank SPF 30 moisturizer and your preferred cleanser.

• Use after cleansing, before moisturizer and SPF
• Avoid direct contact with eyes and apply consistently for visible improvement
• Works well under makeup and alongside other Collagen Bank products
