Sun-baths and skin Eruptions
As a general rule, one should avoid sun-baths, or modify either the after-treatment or the manner in which they are taken if they are followed by depression instead of by exhilara¬tion. If there remains any erythema from the previous sun-bath, it may be better to postpone the next treatment until this has disappeared. If the skin is scaling or peeling from previous sun-baths one should either wait until the desquama-tion is completed, or remove the dead scales by friction with hand, towel, or flesh-brush, for these scales absorb the ultra¬violet rays and prevent them from reaching the live skin where they are needed.
