Neutrogena Collagen Bank Vitamin C Face Serum 0.5 fl oz — 15% Vitamin C, 2% PHA Brightening & Collagen Support

Neutrogena Collagen Bank 15% Vitamin C Face Serum is a high-potency brightening serum that supports existing collagen and helps build new collagen while improving skin tone and glow.

This lightweight, fast-absorbing serum pairs 15% pure vitamin C with a patented micro-peptide delivery system and 2% PHA to target dullness, uneven tone, and early signs of aging. Designed to penetrate multiple surface layers, the formula aims to leave skin looking plumper, visibly brighter, and more radiant without heavy residue. It’s dermatologist-tested, non-comedogenic, and formulated without dyes, parabens, sulfates, phthalates, or fragrance for everyday use under makeup.

How does this serum improve skin brightness and tone?

The concentrated 15% vitamin C works as a brightening agent to reduce the appearance of discoloration and uneven tone. Combined with exfoliating PHA, it helps smooth texture so light reflects more evenly across the surface of the skin. Regular use supports a clearer, more luminous complexion.

• 15% pure vitamin C to visibly reduce dark spots and dullness
• 2% PHA gently exfoliates and hydrates without harsh irritation
• Lightweight liquid texture absorbs quickly for layering under makeup

What makes the micro-peptide technology different?

The serum uses a patented micro-peptide that’s engineered smaller than many common peptides, enabling deeper delivery through multiple surface layers. That targeted delivery is intended to better support collagen already present in the skin while encouraging new collagen production. The combination enhances firmness and helps skin look plumper over time.

• Micro-peptide technology optimized for deeper penetration
• Supports collagen structure for a firmer-looking surface
• Formulated to layer smoothly with other skincare and makeup

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

Neutrogena Collagen Bank serum is allergy-tested and non-comedogenic, formulated without common irritants and fragrance to minimize breakouts and sensitivity. The inclusion of PHA offers gentle exfoliation and hydration, often better tolerated than stronger acids. Patch test if you have highly reactive skin and avoid the eye area.

• Non-comedogenic: won’t clog pores
• Free of dyes, parabens, sulfates, phthalates, and fragrance
• Dermatologist-tested and allergy-tested for everyday layering

How should I add this serum to my daily routine?

Apply to clean, dry skin on face and neck, avoiding the immediate eye area; follow with a moisturizer and broad-spectrum sunscreen each morning. For best results, pair with Neutrogena Collagen Bank SPF 30 moisturizer to protect and maintain visible collagen benefits. Use consistently as part of your morning or evening routine for ongoing brightening and plumping effects.

• Use after cleansing and before moisturizer or sunscreen
• Works well under makeup due to fast absorption
• Combine with Collagen Bank SPF 30 for daily protection and synergy

Who is this for? If you want a dermatologist-tested, fragrance-free serum that targets uneven tone, early signs of aging, and loss of firmness without heavy creams, this Neutrogena Collagen Bank vitamin C serum is designed for you. It’s suited to those seeking a stronger vitamin C concentration paired with gentle exfoliation, people who wear makeup daily and need a fast-absorbing layer, and anyone building a collagen-focused skincare routine. Avoid direct contact with eyes and consult a professional if you have very reactive skin concerns.
