Cos de Baha Retinol 2.5% Serum 30ml (RS)

✨ Introduction

Cos De Baha Retinol 2.5% Serum (RS) 30ml is a high-strength Korean anti-aging serum formulated to reduce fine lines, improve skin texture, and boost collagen production. With 2.5% retinol supported by hyaluronic acid and niacinamide, it helps smooth wrinkles, fade dark spots, and refine pores. Its lightweight, fast-absorbing texture makes it ideal for nighttime use in Bangladesh’s humid climate—especially for aging, textured, or acne-prone skin.
