What are pimples
The skin with its appendages performs some very important functions:
- protects against many harmful external influences
- has a function of Thermo regulator
- is an important sensory, absorb and exclusion organ
- participates in many enzymatic, biochemical and immunological processes
Irregularities in the functioning of the skin can be very distracting and annoying.
The skin is one of our indispensable body organs. Covers 1, 2 and 1, 8 per square meter of body surface area. It consists of several layers: epidermis, dermis and subcutaneous tissue.
It contains skin appendages: sebaceous glands (secrete fat), sweat (excrete perspiration), hair and nails.
Sebaceous glands are located in one of the lower layers of skin with the hair follicle. Produce tallow (mixture of glycerides, fatty acids, squalene, wax esters), this is eliminated by glandular passage in the upper part of the hair follicle and then to the surface. In some areas (e.g. lips), the fat flows directly on the surface.
Sebaceous glands, the most densely planted on so called seborrheic places: the scalp, ears, around the eyebrows, the nose and between it and the upper lip, the chin, over the breastbone, between the shoulder blades and around the navel. In these areas the skin is more oily.
Sebaceous glands are not present on the hands and feet. On the production of sebum affect hormones: androgens (testosterone), promote secretion, estrogens inhibit it. Malfunction of sebaceous glands is called disseborrhea and if too much sebum is secreted, we are talking about seborrhoea, if too little, we talk about sebophase. In particular seborrhoea you make your face look like a pizza.
Pimples. What are pimples and what cause pimples
You’ve probably found that for the formation of spots sebaceous glands play a key role. Inside sebaceous glands under the influence of testosterone forms and collects fat, which, is excreted through the passage to the skin surface. This is why your skin looks greasy and light, especially when too much sebum is secreted.
Also, some properties of fat, such as color, density, composition and quantity vary under the influence of testosterone. Due to changes in passage and fat composition, can be passage of gland narrowed, so the fat is excreted more slowly or not at all. The result? Pimples!
Some pimples are smaller, others larger, some are colored darker, others red, some are painful, others not. Pimples are divided roughly in two forms: non-inflammatory and inflammatory.
Non-inflammatory form of pimples
- open comedo: occurs when in the sebaceous passage forms a cap, which is originally a white-yellow, in a few weeks because of skin pigment and fatty acid oxidation in tallow (and not because of lack of personal hygiene!) darkens
- closed comedo: is convex over the surface of the skin and in glandular openings cap is not seen
Inflammatory forms of pimples:
- papule is a tiny red induration
- pustules arise when purulent papules; is yellow
- nodule (nodules) occurs when inflammation takes place in the deeper layers of skin on the surface we see the formation of larger red round
- nodule cyst can develop from the nodule and is greater than it
