Who was that masked woman?

Patented in 1875 Madam Rowley’s Toilet Mask was a flexible mask made of India rubber and designed to be worn during the hours of sleep to beautify, bleach and preserve the complexion. “To excite perspiration with a view to soften and clarify the skin by relieving the pores and the superficial circulation, or to apply unguents or other medical preparations to the skin of the face for the palliation or cure of cutaneous eruptions, blotches, pimples or other similar complexional defects.”

Efficacy not withstanding it inspired many other derivative and copycat inventions, many we still ‘enjoy’ today.
