Melanocytes play a role in the process led to a brown color when the skin is exposed to the sun. Meanwhile, Langerhans cells capture undesirable microorganisms such as viruses and bacteria.
The second layer, the dermis, collagen must be grateful to the filling. Collagen is what makes skin elastic and strong. The third layer called the hypodermis (subcutaneous). This layer of fat. Its mission provides cushion when the leather goods are stressed by anything and protects the body from temperature or the temperature around it.
Uncomfortable
As a front guard, the skin becomes the primary guardian of the body except the hair. Not surprisingly, susceptible skin problems. Acne, for example. This is the most common problems experienced by adolescents and adults.

When the acne is gone, minor damage (scar) could appear on the face. Difficult to understand is why in some people complete this scar can be lost, while in others a bit difficult.
Another disturbance is rosacea. He has a characteristic red spots at an early stage appearance. This condition is permanent and immediately followed by phases of inflammation and the resulting papules (small bumps on the skin) and pustules (pus-filled bumps on the skin, less than 1 cm diameter).
Although the exact cause is unknown, several risk factors can be identified. For example, alcohol consumption, food berlada, and hot drinks, and excessive sun exposure and the white race.
Psoriasis is one type of skin disease is a manifestation of the rapid life cycle of keratinocytes, epidermal cell types in the network. This is experienced by at least 2 percent of people around the world.
These cells accumulate and form red patches or plaques rather thick silvery, spread quite widely throughout the body. Such a way as skin would invite curious stares from people around him, so people often feel uncomfortable.
Disturbance acne, rosacea, and psoriasis makes people feel anxious, even depressed, and can lead to serious consequences on the personality and professional life.

Carcinoma is a cancer that attacks adults. The most frequent occurrence is the appearance of basal cell carcinoma or contour-shaped tumor that was quite impressive with a variety of forms.
Squamous cell carcinoma is the kind of dangerous. He is somewhat difficult to diagnose and cause quite a lot and a large wound. If not immediately addressed, the cell would be lethal.
Actinic keratosis (solar keratoses) should be frequently monitored closely because the potential to become very large cell carcinoma. He emerged from the effects of ultraviolet light. Damage or chaos appear in the form of tiny dots pink. When touched, the skin feels rough and progressively will form a scab gray or white. This species appears only in parts of the body exposed to sunlight.
