Man has always felt the need to care for his body and, consequently, beauty. Ancient Egyptians used oils and creams to protect the skin against dry and hot climate. Their base contained natural ingredients mainly myrrh, thyme, marjoram, chamomile, lavender, lily, peppermint, rosemary, cedar, rose, aloe, and olive, sesame, and almond oils.

They received perfumes consisting of essential oils and rose water, used olive oil as a cleaning agent for the skin and, in order to prevent wrinkles, they produced creams that included, for example, figs or bananas.
