Can sunblock be used on Shabbat, if it’s a spray?

HaRav Shmuel Eliahu and HaRav Avraham Yosef wrote that if it's a spray (not cream), than it's permitted, for it's not a medicine, but just a preventive measure, so one can surely rely on their opinion, especially regarding this rabbinic issue (medicine for the healthy is not a Torah prohibition).
