The first finding of cosmetics comes from Ancient Egypt, some 6,000 years ago. The worldwide market for cosmetics now stands at more than $500 billion and is anticipated to raise $750 billion by 2025, growing at the rate of 6%. Growth in global economies, changes in lifestyle, increased competition for skin and sun care products, due to varying weather conditions, are encouraging the growth of the cosmetics market. Rising interest in natural, herbal, and biodynamic skin care products creates new opportunities for manufacturers to innovate and develop new products in line with consumer preferences. The book "A Comprehensive Chemical and Pharmacological Review of Cosmetics" mostly focuses on the chemical and pharmacological aspects of using these additives along with the main ingredients. This rising market needs constant multifaceted control, i.e. monitoring of harmful chemicals and biological degradation. Adding artificial ingredients to consumer cosmetic products is a common practice for increasing cosmetic efficacy, maintaining cosmetic effectiveness, and producing a longer-lasting, more viable product. The chapters of the book cover an extensive list of topics, including, but not limited to, the basics of skincare products, such as the raw materials of cosmetics and their application; technical implications of the merits and demerits of ingredients used, as well as theoretical knowledge; skin creams, lighteners, tanners, sunscreens, facial powders, acne protection, and anti-aging formulations. Harmful cosmetics pose a risk to consumers owing to the presence of impermissible or prohibited substances under the current cosmetic legislation. Cosmetic hazards and regulations are therefore discussed in detail to give readers a clear idea.
