The most common explanation is based on the expansion of skin sip of water, especially in areas devoid of hair, since they are the producers of protector sebum. However in 1935, Lewis and Pickering doctors note the absence of these wrinkle in suffering paralysis patients. This suggested a mechanism different from a simple expansion by water absorption (stem cell serum for wrinkles).
Indeed, the longitudinal compression of thin object tends to trigger a sudden change of shape (called buckling) resulting in a curved shape. The presence of soft substrate tempers spontaneous great amplitude of buckling and bending forces to repeat itself (these are the wrinkle). The origin of compression of thin layer can also be the shrinkage of soft substrate (such as a fruit-drying), the dilatation of thin layer (for example due to heating, the swelling by a solvent or cell growth in case of living tissue) or an overall compression of substrate and of thin film by an external mechanical action.
Botulinum toxin is a neurotoxin protein produced by the bacterium "Clostridium botulinum" used (type A) in diluted form to temporarily disappear in aesthetic facial wrinkle or fine lines by paralyzing the muscles involved in its appearance when applied intramuscularly. In world there are already several commercial products diluted botulinum type A for cosmetic purposes; but the old brand is concocted and Botox, whose record belongs to company Allergan Inc (USA) and also (along with type B) has therapeutic use in diseases such as migraine, cervical dystonia or (torticollis) and hiperdhidrosis between others.
The cause is multifactorial and Wrinkle different in each individual. Among the factors include: the genetics, environment, ultraviolet rays, pollution and food habits, smoking, and ongoing stress. Aging wrinkle occur in principle by the called glycation tissue resulting in accumulation of collagen to extent that the cell parts and wear unbalance between cells and connective tissue.
The skin is the largest organ of body humano1 or animal. In humans occupies approximately 2 m, and its thickness varies between 0.5 mm (eyelid) and 4 mm (heel). Its approximate weight of 5 kg. It acts as a protective barrier that insulates the body from surrounding environment, protecting and helping to keep intact their structures, while acting as a communication system with the environment, and this varies by species. Anatomically standard measures within human skin is referenced. Also known as integumentary system.
Frown lines (also known as wrinkle between the eyebrows or the glabella) vertical wrinkle on the forehead and between the eyebrows. Wrinkle of crow's foot (also known as periorbital wrinkle) wrinkle from the outer corner of eyes in direction of ears. Bitterness wrinkle (also called bitterness fold, Jugo-chin groove or cleft lip and chin groove) wrinkle starting from the corners of mouth to chin.
The skin can suffer from several different diseases, called dermatitis, and seborrhea. These are studied by the disciplines of dermatology and pathology, mainly. In humans, male skin produces more sebum than women due to increased amount of androgens (male sex hormone) produced by the male. As a result, men's skin is thicker and oily.
There are treatments to reduce wrinkle that are practiced by doctors or dermatologists trained in cosmetic and other cosmetic surgeons: injections of wrinkle fillers: hyaluronic acid (wrinkle filling) and botulinum toxin (Botox). Rhytidectomy is a cosmetic surgery to correct sagging skin. This includes head and neck rejuvenation wrinkle treatment by laser. Some laser ablative current single treatment work well for beginners subsidence. The skin of hands and feet (especially) wrinkle temporarily, but very significantly, after a prolonged bath.
