La combinación de bakuchiol y retinol en esta ampolla me ha sorprendido. Mis líneas finas lucen menos visibles después de una semana, dejando mi rostro más luminoso y terso. Definitivamente un producto recomendable para quienes buscan efectividad sin irritación.
Nina Rodríguez from Chicago, USA –
Initially, I was doubtful about adding yet another serum to my skincare routine—especially one boasting ingredients like bakuchiol and retinol. But the allure of combining these potent components in a single bottle captured my attention during a quick stop at a health store in Chicago. After using Cos De BAHA L1 for several weeks, I’m surprised by its effectiveness; fine lines seemed visibly reduced while dark spots faded gracefully into softness! The mild texture offers comfort without overwhelming even slightly reactive complexions like mine. If you value straightforward brilliance for maintaining youthful glow, consider integrating this elixir into your regimen.
