Ideal para refrescar la piel irritada
Esta bruma hidratante me ha parecido excelente. Me deja la piel fresca, humectada y con una sensación muy suave desde el primer uso. Humedece lo justo, se absorbe rápido y no deja la piel pegajosa. La conocí por la esposa de J Balvin en sus videos y decidí probarla. Yo sufro de acné y muchas veces mi piel está enrojecida, inflamada y sensible, y esta bruma realmente me ayuda a refrescarla cuando la siento caliente o irritada. No es un tratamiento para el acné como tal, pero sí me calma la piel y me baja un poco la inflamación, lo cual agradezco muchísimo. Es ligera, refrescante y perfecta para usar en cualquier momento del día cuando necesito darle un “respiro” a mi piel. Me ha funcionado muy bien. La recomiendo mucho, especialmente si tienes la piel sensible o con brotes.
