Cos De BAHA Retinol 2.5% Serum (RS) – 30ml

Overview

Cos De BAHA RETINOL 2.5% SERUM is a 30ml clinical-strength anti-aging treatment featuring pure 2.5% retinol for dramatic wrinkle reduction, texture refinement, and pigmentation fading. This potent K-beauty serum combines encapsulated retinol with niacinamide, hyaluronic acid, vitamin E, and soothing botanicals like aloe vera, green tea, rose damascena, and lavender to accelerate cell turnover while minimizing irritation. Its lightweight, fast-absorbing formula penetrates deeply without greasiness, making it ideal for Bangladesh’s humid climate where premature aging from sun and pollution accelerates. Fragrance-free and advanced encapsulation technology reduces peeling for resilient, youthful skin transformation.

Key Benefits

• 2.5% retinol stimulates collagen production and accelerates cell renewal dramatically.
• Niacinamide brightens hyperpigmentation and strengthens skin barrier.
• Hyaluronic acid hydrates deeply to plump fine lines and prevent dryness.
• Vitamin E provides antioxidant protection against free radical damage.
• Botanicals soothe irritation and reduce post-retinol redness.
• Improves texture, fades acne scars, and evens skin tone effectively.

Who It’s For

Advanced users with mature, sun-damaged, or acne-scarred skin seeking prescription-strength results without a doctor’s visit, especially Bangladesh professionals facing accelerated aging from tropical UV exposure. Ideal for experienced retinoid users comfortable with 2.5% concentration. Dry/dehydrated types will appreciate the built-in hydration preventing typical retinol flaking.

How It Works

Encapsulated retinol (2.5%) releases gradually to minimize irritation while binding to retinoid receptors for gene expression changes promoting collagen synthesis. Niacinamide boosts ceramide production as sodium hyaluronate plumps multiple layers. Tocopheryl acetate stabilizes retinol while aloe and green tea calm inflammation. The result is accelerated epidermal turnover yielding smoother texture, faded pigmentation, and firmer contours over 8-12 weeks.

How to Use

**Night only:** After toner, apply 1-2 drops (pea-sized), starting 1-2x weekly. Build tolerance over 4 weeks. Follow with moisturizer; use SPF50+ religiously daytime. Avoid eyes/lips; patch test mandatory. Buffer with Kioraa hyaluronic serum if irritation occurs. Discontinue if excessive peeling develops.
