We reorder this item frequently. The cotton content is excellent and is thick. It doesn’t pull off easily. The quantity in the box is plenty to get our family of four through a month. If you have skin sensitivity, these are for you. We have sensitive skin in our family and have no concerns with this product. This product cleans well and the shape of the actual cotton tip holds well.

"Máxima protección sin sensación pesada"

Size: 1.69 Fl Oz (Pack of 1)

"El protector solar VGO-50 me ha sorprendido gratamente. Tiene un factor de protección muy alto, ideal para pieles sensibles o exposiciones prolongadas al sol. Se absorbe rápido, no deja sensación grasa ni pegajosa y su aplicación es muy fácil. Después de usarlo, siento la piel protegida y cómoda todo el día. Lo recomiendo para quienes buscan una defensa efectiva contra los rayos solares."
