Vitamin C 15% Serum Va - 30ml

This COS DE BAHA serum is listed as a 30ml face serum with Vitamin C in the title and tag, plus existing copy that identifies an AHA and vitamin C focus. It is a targeted treatment-style step for users who want a lightweight layer between cleansing and moisturizer without adding a complicated routine.

Why It Stands Out

The listing is specific about the 15% Vitamin C positioning, which gives this serum a more focused role than a general hydrating serum. The AHA reference in the existing product copy also makes patch testing and careful routine pairing important.

Best For

Best for skincare users comparing K-Beauty face serums for tone, texture, and routine simplicity, especially those who already use moisturizer and daytime sunscreen consistently.

How to Use

Apply a small amount after cleansing and toner, then follow with moisturizer. Introduce gradually, and use sunscreen during daytime routines.

Benefits

• Vitamin C-focused serum format gives a targeted routine step.
• 30ml bottle is easy to place into AM or PM skincare routines.
• Light layering style works before cream or moisturizer.
• AHA mention supports careful texture-focused routine planning.

Good to Know

Do not combine too many active products at once when first introducing this serum. Patch testing is a sensible step, especially for sensitive or exfoliant-heavy routines.
