4 Birds 1 Serum

4 Birds 1 Serum

5x Retinoin Treatment

One serum. Four results. 4 Birds 1 Serum is a next-generation retinol treatment formulated to tackle fine lines, wrinkles, enlarged pores, and blemishes — all at once, without the irritation that makes traditional retinol products hard to stick with.

The secret is a two-part innovation: the proprietary Retinoin® Active Pro-Penetrant delivery system drives All-trans-Retinol — a clinically proven, pure-form active retinoid — deeper into the skin for a heightened level of retinization. Bakuchiol, a plant-derived natural complement to retinol, amplifies the antioxidant benefits while visibly reducing the redness and irritation that can come with stronger retinol formulas.

The result is a smarter retinol experience: more effective, more tolerable, and more complete. Consistent use improves skin texture, clarity, firmness, and overall radiance.

For facial use only. Introduce gradually as part of your PM routine.
