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

Neutrogena Collagen Bank 15% Vitamin C Serum is a fragrance-free, fast-absorbing face and neck serum formulated with 15% pure vitamin C, patented micro-peptides and 2% PHA to support collagen, even skin tone and deliver a plumping, glowing look.

This lightweight serum combines a potent dose of vitamin C with micro-peptide delivery and gentle exfoliating PHA to target uneven tone and reinforce the skin’s collagen support. Designed to sink in quickly without clogging pores, it layers smoothly under makeup and pairs with sun protection for a complete daily routine. The formula is dermatologist- and allergy-tested, non-comedogenic, and free of dyes, parabens, sulfates, phthalates and fragrance.

How does this serum help brighten and even skin tone?

The serum uses 15% pure vitamin C to visibly reduce the appearance of discoloration and promote a more uniform complexion. Vitamin C is a brightening antioxidant that helps diminish the look of dark spots and supports skin radiance over continued use.

• 15% pure vitamin C for visible brightening results
• Lightweight liquid texture absorbs rapidly into skin
• Designed for daily layering under moisturizer and sunscreen

What makes the micro-peptide technology different?

Neutrogena’s patented micro-peptides are engineered to be smaller than standard anti-aging peptides so they can reach deeper surface layers. This enhanced delivery aims to support the skin’s existing collagen while helping to promote a plumper appearance.

• Micro-peptides measured to penetrate more than 10 surface layers
• Optimized delivery for collagen-supporting activity
• Pairs with complementary Collagen Bank moisturizers for boosted results

Is this serum gentle enough for sensitive or daily use?

The formula is allergy-tested, dermatologist-tested and fragrance-free, and it uses 2% PHA — a skin-friendly exfoliating hydrator — to smooth without harsh irritation. It’s non-comedogenic and intended to layer well beneath makeup for everyday wear.

• 2% PHA provides gentle exfoliation and hydration
• Fragrance-free and free from common irritants like parabens and sulfates
• Non-comedogenic, suitable to use under makeup

How should I use this serum for best results?

Apply the serum to clean skin on face and neck, avoiding the immediate eye area. For a complete regimen, follow with a moisturizer from the Collagen Bank line and always finish with broad-spectrum sunscreen during daytime.

• Use daily after cleansing, before moisturizer and sunscreen
• Avoid the delicate eye contour area
• Combine with Neutrogena Collagen Bank SPF moisturizer for enhanced collagen support
