Fragrances are added as a finished product to enhance the look and fragrance of the product. Examples of common fragrances are rose, lemon, orange, vanilla, tangerine, jasmine, sandalwood, and ti leaf. Colorants are added to give the appearance of the product absorbing into the skin to change the color of the skin.

Preservatives are generally considered good for the health of people but when applied to the skin, they increase the rate of aging by producing plaque and reduced blood flow. Commonly used preservatives in cosmetics include parabens, phthalates, sodium benzoate, and acrylamide. Lipsticks and lotions are also considered to contain some level of cosmetics, usually as fragrance, because they are combined with other ingredients. Lipsticks that contain alcohols and other chemicals to extend their shelf life may increase the risk of cancer. Many lipsticks and lotions have been banned in some countries and are not allowed in beauty products. These chemicals can clog the blood vessels, cause allergies, skin rashes, dryness of the skin, and may develop cancer.
Surfactants are present in many personal care products, such as shampoos and conditioners, and are used as stabilizers in lipsticks, lip glosses and balms. These chemicals should be avoided by individuals with high blood pressure or those with a kidney disorder. Some surfactant chemicals added to lipsticks and lip glosses are propyl gallate (a derivative of vitamin B) and glycolic acid, which are considered cancer-causing agents.
The chemicals added to fillers, including polymers and starch, in cosmetics are used to increase the stickability and texture, as well as to give products a velvety appearance. However, these ingredients may cause chemical skin reactions, including allergic reactions and increased risk of scarring. While most cosmetics include some preservatives, some actually contain ingredients that have been found to cause cancer. Cosmetics that are made from synthetic chemicals can be very dangerous for anyone to use.
