Know About Common Skin Diseases:
Acne is the most common skin disorder occurring during the second and third decades of life.
It usually involves the face, and frequently the chest and back. At puberty the oil glands in the skin begin producing an oily material called sebum. Sebum is discharged onto the skin surface through pores. With acne the oil glands become plugged causing pimples, blackheads, whiteheads, and cysts.
Scabies is a common, itchy skin reaction caused by a parasitic mite (Sarcoptes scabiei) that affects only humans.
The mite is very small and can only be seen under a microscope. The female mites burrow under the skin to feed and lay eggs. These mites cannot jump or fly and in most cases can only survive for 3 days off of the body. An infested person typically has only 10-15 mites on their body.
Tinea is a fungus that can grow on your skin, hair, or nails. Fungi live everywhere, but humans and fungi usually co-exist in harmony.
Tinea is transmitted by direct contact with an infected person, object, or animal. Some kinds of fungi live on damp surfaces, like the floors in public showers or locker rooms. You can even catch a fungal infection from your pets.
Psoriasis is a common skin problem. It causes a thick, rough, dry buildup of your outer layer of skin.
