The earliest known cosmetics come from the 1st Dynasty of Egypt (about 3100-2907 BC). Tombs of this era have yielded unguent jars, and from remains of later periods it is evident that the unguents were scented. Such preparations, as well as perfumed oils, were extensively used by both men and women to keep the skin supple and unwrinkled in the dry heat of Egypt. Egyptian women also developed the art of decorating the eyes by applying dark green colour to the lower lid and by blackening the lashes and the upper lid with kohl, a preparation made from antimony or soot. It is likely that the Jews adopted the use of cosmetics from the Egyptians, since references to face painting appear in the Old Testament. In one of the most tender life period of humans - adolescence, teenage skin gets covered with acne and pimples. From 80 to 100 percent of teenagers suffer from an acne problem and more and more adult women come to face this blemishes problem too, possibly after taking contraceptive medicines or hormonal disorders and stresses. It was thought previously that an acne problem was caused by wrong nutrition or dirty skin. Greasy skin, psychological factors like stress are blamed nowdays for undergoing through teens skin problems . The latest research have shown that teens skin problems are promoted by keratogialinis accumulation, bacteria and fat in separate hair follicles. The most vulnerable follicles are settled on face, chest and upper back. Teens skin problems are also promoted by bad heredity to a greater or lesser extent. Hormon background is another reason for acne problem, and it is thought that excessive concentration of hormones can promote acne. Women are exposed to this problem during a menstrual cycle. Application of contraceptives also changes a hormonal level in human body and can be an origine of acne problems. Besides, a stress has an influence on the adrenaline surge and it promotes acne as well. Cosmetics products using fats plug up interstice and cause pimples, too. Skin remedies that do not plug interstice up are best applications for fat skin inclined to eruptions. People with fat and acne skin are recommended to use cosmetic remedies deprived of fat, because excessive moist promotes teens skin problems. In summer desorders develop more often, however, some people are relieved by the sunshine. Amount of hormones in blood of adolescents increases greatly, what makes sebaceous glands secrete more skin fat. Hormones can be a reason for a keratin excess, which blocks follicular outlets causing acne. Adult people can also experience skin problems caused by one of the reasons obove. Acne (a closed pimple has a white top, an opened pimple has a black top) is formed when clots of keratin and skin fat plug a hair follicle. Some pimples can develop into typical skin erosions. Such pimples and papula are generated by acne when the wall of a plugged up follicle gets broken and dead skin cells, fat and bacteria come to derma. Later, amount of white blood cells increases, that prevents infection getting into lower skin layers. It causes skin reddening while white blood cells mixed with dead skin cells accumulate in a follicle producing pus. Then a red pimple with a yellowish head appears on skin. You'd better not squeeze pimples out because bacteria can get deeper in skin and a scar may set in. If you don`t touch a pimple, white blood cells will gradually destroy living bacteria and it dissapears. If you have teens skin problems, then you should get in touch with good clinics around you.
