Natural skin care is the care of the skin (the largest organ of the boy) using naturally-derived ingredients (such as herbs, roots, essential oils and flowers) combined with naturally occurring carrier agents, preservatives, surfactants, humectants and emulsifiers (everything from natural soap to oils to pure water). The classic definition of natural skin care is based on using botanically sourced ingredients currently existing in or formed by nature, without the use of synthetic chemicals, and manufactured in such a way to preserve the integrity of the ingredients.
