The Vitamin C 13 Serum - 20ml

Cosrx - The Vitamin C 13 Serum - 20ml is a K-Beauty face serum from Cosrx with a confirmed vitamin C 13 product title. It is a focused treatment step for buyers who want glow support and a more even-looking routine without choosing an unspecified brightening serum.

Why It Stands Out

The 13% vitamin C detail is clear in the product name, making the strength a major selection factor. The 20ml size is also typical for active serums that users introduce carefully and store with attention to freshness.

Best For

Best for shoppers comparing Cosrx face serum in Bangladesh and wanting a vitamin C product for dull-looking skin, uneven-looking tone, or morning glow routines.

How to Use

Apply after cleansing and toner, then follow with moisturizer. Use sunscreen in daytime. If new to vitamin C, start slowly and monitor skin comfort.

Benefits

• Vitamin C 13 focus supports brightening routines.
• Face serum format layers under moisturizer.
• 20ml size suits careful active use.
• Helps skin look fresher and more even.

Good to Know

Store away from heat and strong light. Do not use on irritated skin, and patch test before regular application.
