Cos De BAHA Retinol 2.5% Serum (RS)

Cos De BAHA Retinol 2.5% Serum (RS) is a lightweight, fast-absorbing K-beauty serum with a high-strength, prescription-free retinol complex — positioned as an accessible gold-standard anti-aging treatment for skin renewal and tone correction.

This serum is formulated strictly for PM use and should be applied after cleansing and toning, before moisturizer, as the active step in your evening routine.

The formula leads with an aloe vera base for soothing hydration, then delivers its core actives: Retinol (Vitamin A derivative) to accelerate cell turnover and smooth visible aging; Sodium Hyaluronate to replenish moisture and plump skin; Niacinamide (Vitamin B3) to even tone and strengthen the barrier; and Tocopheryl Acetate (Vitamin E) for antioxidant protection and skin softening. Botanical extracts including Camellia Sinensis (green tea) and Rosa Damascena add further antioxidant & calming support.

• Visibly reduces fine lines, wrinkles, and crepe-like skin texture with continued use by boosting epidermal cell turnover.
• Fades hyperpigmentation, age spots, and post-acne marks for a more even, luminous complexion over time.
• Helps regulate excess sebum production and minimise the appearance of enlarged pores, making it suitable for oily & acne-prone skin types.
• Free from parabens, sulphates, gluten, formaldehyde, artificial fragrance, and artificial colorants — a clean-formulated option at an accessible price point.

How to Use: Apply every evening after cleansing and toning. Dispense 1–2 drops onto fingertips and gently pat into face and neck until fully absorbed. Follow immediately with a nourishing moisturiser to buffer potential retinol irritation. New users should begin with 2–3 applications per week, gradually increasing frequency as skin builds tolerance. Always apply SPF the following morning, as retinol increases photosensitivity. Avoid the eye contour, and discontinue use if persistent irritation occurs.
