"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."

Great Sunscreen
Size: 1.69 Fl Oz (Pack of 1)
This absorbs quickly, is non-greasy, and leaves skin feeling smooth and soft (though it's no substitute for moisturizer). All in all, a great product, though I haven't tested it extensively in bright sunlight. However, I deducted one star for the smallish tube and highish price.
