Abstract
Numerous concerns have been raised on the side effects of the prolonged
usage of synthetic compounds in cosmetics production, including skin damage due to
inflammations, rashes, and itching, just to mention a few. These skin side effects have
been reported to be linked to the break-down of homeostasis of the repair system
against deoxyribonucleic acid (DNA) and tissue destruction. These can lead to
accelerated aging, melanogenesis, and cell growth senescence or even cause cancer of
the skin. Efforts to overcome these problems associated with synthetic cosmetics have
led to the use of natural cosmetics of plant and animal origin. Natural cosmetics have
been found to contain essential oils and other extracts that can alleviate or inhibit skin-associated problems, such as eczema, allergy, acne, dryness, and discoloration, while
also containing anti-aging, anti-tyrosinase, antioxidants, and anti-inflammatory
substances. In this chapter, some cosmetics products from plants (herbs) and animal
extraction are highlighted alongside their applications in skin care. At the same time,
also, the future perspectives and recommendations of these natural extracts are
proffered.
