Personal care products are consumer products which are applied on various external parts of the body such as skin, hair, nails, lips, external genital and anal areas, as well as teeth and mucous membrane of the oral cavity, in order to make them clean, protect them from harmful germs and keep them in good condition. They promote personal hygiene and overall health, well-being and appearance of those body parts. Toiletries form a narrower category of personal care products which are used for basic hygiene and cleanliness as a part of a daily routine. Cosmetic products, in contrast, are used for personal grooming and beautification (aesthetically enhance a person's appearance). Pharmaceutical products are not considered personal care products. Most of the personal care products are rinsed off immediately after use, such as shampoos, soaps, toothpastes, shower gels, etc. A few personal care products, however, are left on the applied surface such as moisturizing cream, sunscreen, etc. The global market size of the personal care products industry is several hundred billion US Dollars (as of early 2020s). Procter & Gamble, L'Oreal, Johnson & Johnson, Unilever, Colgate-Palmolive, Gillette, Avon, Natura & Co, Kimberly-Clark and Shiseido are some of the world-leading companies in personal care products industry.
