I wear foundation daily. Should I let my skin breathe?
Skin cannot respire—it receives oxygen from the bloodstream, not from the outside air. Foundations contain fragrances, oils, or preservatives that aggravate skin, so choose makeup best suited for your skin type (i.e. oilfree foundation for oily skin). It’s not necessary to give skin the day off as long as makeup is thoroughly removed at the end of the day.
