Neutrogena^® Collagen Bank 15% Vitamin C Glow Serum, 0.5 Fl. Oz

Collagen Bank vitamin C face serum stands out with its high concentration of pure vitamin C and patented micro-peptide technology that helps visibly fade dark spots. This serum is also powered by PHA — an exfoliator and hydrator — to improve skin texture and build natural collagen, leaving your skin looking youthful without irritation.

Dermatologists recommend vitamin C for face because it’s a powerful antioxidant that brightens skin, visibly reduces discoloration, and evens skin tone. Our serum vitamin C formula also helps boost collagen production, visibly improving elasticity and supporting firmer, healthier looking skin over time.

It’s normal for a vitamin C facial serum to change color when exposed to air or light, as the ingredient oxidizes. However, the product remains effective. To preserve your vitamin C face serum, store it upright in a cool, dark place and tightly sealed when not in use.

Use our face serum daily after cleansing and before applying moisturizer or SPF. For best results, pair the vitamin C serum with Collagen Bank SPF in the morning and Collagen Bank Moisturizer at night for plump glowing skin. This multi-step routine helps boost collagen while keeping your skin hydrated and protected.

In a clinical study:

• After 1 week: 98% agreed skin’s complexion was brighter, texture was smoother, & skin was more radiant

• After 4 weeks: 95% of participants agreed their skin tone was more even

• After 12 weeks: 100% agreed skin was plumper

When used once daily, the Collagen Bank 15% vitamin C facial serum lasts around 45 days — giving you over a month of results-driven skincare in every bottle.
