Medical illustration, or biomedical visualization, is the practice of biomedical communication, specializing in visual representations of aspects of medicine and science. Common forms of expression include digital art, physical modeling, 2d animation, 3d animation and app development, among others. Biomedical illustrators are able to utilize their strong drawing skills together with their background biology, botany, zoology and other sciences. Medical illustrators draw a wide range of subjects from surgery to human and veterinary anatomy; animal life and plant life; chemical, molecular, and atomic structuress, and geologic and planetary formations.
Acne vulgaris, simply known asacne, is a progressive skin disease in which the sebaceous glands of hair follicles are clogged with oil from the skin (sebum) and dead skin cells. It is diagnosed with the appearance of characteristic whiteheads, seborrhea (increased oil-sebum secretion), blackheads, pimples, oily skin, and occasional scarring of the skin on the cheek, forehead, chin, and back. These are the places on the body with the densest population of sebaceous follicles.
Acne affects almost 80 percent of teenagers and young adults. The onset of acne depends to some extent on testosterone and androgens which begin to circulate in the body at this time, in both boys and girls. Acne is characterized by comedones (blackheads), papules (swellings without pus), pustules, nodules (gathering of swellings), or seborrhea (excessive sebum discharge). And it can cause hyper pigmentation or even scarring. Acne is increasingly considered to be an inflammatory disease at all the stages of its development. As such, it is clinically treated in a successful way through the use of anti-inflammatory agents at all stages of acne development.
The causes of acne are complicated, multi-factored, and not entirely understood in their full range of mechanisms, despite many years of research. Treatments, likewise, are not perfect. A good result from acne treatment is a reduction of 50% in the appearance of acne.
