Q. (translated) Dear Rabbi. I suffer from a severe Skin Cancer, and I have to use medical cream and sun blocking agents when exiting home, specially under the strong sun of Mexico. (When going to shul on Yamim Noraim). I already suffered three skin surgeries, what can I do on using these protecting creams?
A. You can use creams with a ‘Shinui’ (unusual way) in your severe case. That would involve not smearing the cream directly on your skin, but rather smearing the face on the cream container or a prior prepared tissues. A better way, as is common in your country, if you have a Gentile maid, she could be instructed before Shabbat to do so for you.
