The skin selectively absorbs fat-soluble vitamins A, E and K, and steroid hormones, since the human body is unable to synthesize them. The skin’s capacity to absorb certain substances makes it possible to apply lotions, creams, gels and transdermal patches topically in order to provide therapeutic or medicinal treatment.
The skin plays an important psychological role. It reveals emotions (e.g., shy people tend to blush easily). The skin is also the most visible health indicator (e.g., acne, dermatosis as a result of stress). This living organ that envelops the whole body enables communication between individuals. It affects the perception that you have of yourself, as well as your perception of others. When skin is healthy and problem free, it fulfills its functions optimally, allowing you to feel comfortable and confident.
