Sérum Antirrugas e Linhas Finas — Retinol 0,3% + Óleo de Rícino

I've been using this retinol serum for about three weeks and the fine lines around my eyes are noticeably softer. The castor oil makes it feel less drying than other retinols I've tried, which is a huge plus for my 40-something skin. It's already giving my face a smoother, more even texture.
