COS DE BAHA Retinol 2.5% Serum is an advanced anti‑aging serum formulated to boost skin renewal, smooth fine lines, refine texture, and improve overall complexion clarity. With a potent 2.5% Retinol concentration, this serum targets visible signs of aging, including wrinkles, enlarged pores, uneven texture, and dullness, while supporting skin resilience.

Retinol, a derivative of Vitamin A, is one of the most well‑researched ingredients for stimulating collagen production and increasing cell turnover. The high concentration in this formula makes it effective for those looking to make noticeable improvements in skin texture and elasticity over time.

To help fortify the skin barrier and reduce the risk of irritation often associated with retinol, this serum also contains soothing and hydrating ingredients. It delivers deep nourishment while encouraging smoother, firmer, and more radiant skin.

The lightweight, fast‑absorbing texture allows effective penetration without a sticky or greasy feel, making it suitable for night‑time application. When used consistently and paired with daytime SPF protection, the serum helps reveal healthier‑looking, rejuvenated skin.

COS DE BAHA Retinol 2.5% Serum is ideal for those with early to advanced aging concerns and is suitable for people familiar with retinoids or experienced retinol users. Beginners should introduce it gradually.
