Skin care by the application of cosmetics includes cleansing and toning, solar protection and anti-free radical activity; it includes moisturising, acne treatments, and the treatment of hyper-pigmentation, skin peels and other means of wrinkle reduction.
The active ingredients may be natural oils and extracts or active principals isolated from plants or they may be minerals, synthetic chemicals, or stabilized vtiamins. The form of these compositions varies from sprays to pastes and the packaging, from aerosols and bottles to jars, tubes, and sachets.
Developments in skin care include improved carrier systems and time-release mechanisms, anti-inflammatory and protective ingredients, new active ingredients obtained from botanical sources, the use of microfine oxides for safe sun protection, AHAs for skin rejuvenation, and advances in emulsifier and emollient systems.
Our team categorized personal care ingredients by their origin, chemical structure, and similar biological effects. Categorization is not easy when the selection criteria are so different, and some ingredients may be moved from one category to another over time.
