Cosrx – The Niacinamide 15 Serum – 20ml

Cosrx – The Niacinamide 15 Serum – 20ml is listed in Face Serum and K-Beauty categories with a Niacinamide tag and confirmed 20ml size. The title includes The Niacinamide 15 Serum, so the product can be described as a niacinamide-focused serum while avoiding unverified ingredient details beyond the title and tag. Its compact 20ml format suits targeted use rather than a broad cleanser or cream role.

Why It Stands Out

The product is specific because the active-focus wording is part of the name. COSRX shoppers often compare serums by named ingredient and strength identity, and this listing clearly separates itself from centella, peptide, or retinol products. The smaller 20ml size also makes sense for a focused serum step.

Best For

Best for users who intentionally want a niacinamide-labeled face serum in a K-beauty routine. It is relevant for shoppers concerned with the look of uneven tone, visible pores, or texture, without expecting a promised medical result.

How to Use

Apply a small amount after cleansing and toner, then follow with moisturizer. Use sunscreen in the morning, and introduce gradually if your routine already contains several active skincare products.

Benefits

• Provides a niacinamide-focused serum step.
• Uses the verified The Niacinamide 15 title identity.
• Comes in a confirmed 20ml size.
• Fits targeted tone and texture routines.

Good to Know

This listing does not confirm complete ingredients, skin type suitability, or clinical proof. Keep the serum away from overcomplicated layering if you are testing how it fits your routine.
