Cos De Baha RS Retinol 2.5 Serum 30ml

Cos De Baha RS Retinol 2.5 Serum is a high-strength, lightweight anti-aging serum formulated to support smoother, clearer, and more youthful-looking skin. Designed for those battling wrinkles, uneven tone, and signs of aging, this serum combines retinol, niacinamide, and hyaluronic acid—ingredients widely recognized for their role in promoting skin renewal and improving texture.

Its hydrating base helps minimize dryness, while the gentle formula allows many users to enjoy the benefits of retinol without excessive irritation. With consistent nighttime use, the serum helps refine pores, brighten dull skin, and support a firmer, more radiant complexion.

(If an exact percentage of retinol used is unclear, it’s worth noting that many brands label “2.5% retinol complex” which may not mean 2.5% pure retinol. Cos De Baha publicly uses “2.5% retinol” labeling, but actual concentration may differ based on formulation.)
