Neutrogena Collagen Bank Vitamin C Face Serum - 15ml

Yes, it is formulated for daily use; however, always monitor your skin for sensitivity when applying high-potency actives like vitamin C twice daily.

While it is free from fragrance and dyes, those with extremely sensitive skin should perform a patch test on the inner arm before full facial application.

It is highly recommended to wear a broad-spectrum SPF during the day when using any vitamin C product, as it helps protect the skin while the serum works to brighten it.

Yes, the Neutrogena Collagen Bank line has been tested across all skin tones to ensure efficacy and brightness.

You can layer it, but avoid mixing it directly with products containing retinol or strong AHAs/BHAs at the exact same time to prevent potential skin irritation.

You may be using too much product. Try reducing the amount to 2-3 drops to allow for faster absorption.

High concentrations of vitamin C can cause mild tingling. If irritation persists, discontinue use or alternate application days until skin adjusts.

Vitamin C can oxidize when exposed to air. Keep the bottle tightly sealed and stored in a dark place to prolong shelf life.
