If you wanna prevent acne , it good for you to know and understanding your own skin. With knowing the process and what happened in your skin so you know how to prevent acne. Not only about prevent but also how to treat acne. Because acne have many type of acne and acne causes so acne need good and right treatment.

Glowing flawless skin is a dream of all women. Smooth skin represents beauty, sexual attractiveness and self confidence. Unfortunately, acne turns skin into opposite of smoothness. Red swollen bumps, pus and black dots are ugly on their own, and they are usually followed by unsightly scans and spots that are equally
hard to eliminate.

Skin is the largest organ in the human body. Skin makes up about 15% of our total weight and covers 20 square feet on an average person. Even wrinkled, bruised or age-spotted, skin still protects us from the environment, inhales oxygen, safely cushions our inner organs, feels and sends to the brain all the sensations from the outside world, cools our body systems, eliminates waste and toxins. As if all that wasn`t enough, skin makes us beautiful and unique! That`s why we must keep our skin healthy so that it can glow with beauty and perform its vitally important tasks.

A mechanism more complex than any computer in the world, skin can perfectly repair itself. ln fact, it`s the only organ that can completely restore itself when damaged. All the scratches, cuts, wounds, or hurns heal eventually and most often without a sign.
lf`you suffered a cut, take a look at how fine yet firm skin is at the place of the opening. You will never see a fabric so reliable as skin!

ANATOMY OF THE SKIN

Skin Layers
To understand what happens with your skin when you have acne, you need to know something of the way skin works, so to start l will descrihe in a few words how skin is made up.
Let’s begin with the top layer, stratum corneum is formed of 25-50 layers of dead layered flattened skin cells that are rich in keratin. Stratum corneum protects the skin and continually renews itself by flaking off dead skin and replacing it with newer cells. On most parts of the skin the top dead skin cells layer is very thin, only 0.15 mm deep, and on the palms and soles of the feet this layer is much thinker—about 0.5 mm.

Underneath the stratum cornea is an epidermis, the living top portion of the skin, and a basal membrane, which works as a communicator between two most important skin layers. What we need to know is that acne scarring happens when the basal membrane is broken by acne widespread. To avoid damaging this layer, you rnust treat acne as soon as possible.

Under the epidermis is a dermis, or basal layer. This is the very busy skin layer that delivers nourishment and protective skin cells to epidermis layer. Dermis Layer is formed of collasgen and elastin molecules, two Droteins that provide

the skin with the density and flexibility. Dermis also contains blood vessels, as much as 9 yards of blood vessels per square inch, plus nerve endings. They reach right up to base of the epidermis but don't actually penetrate it. When people have pimples, or inflamed acne lesions, most of the inflammation take place in the dermis, which results in scarring.

The subcutaneous layer is the deepest layer on the skin. It is built of lipocytes,or fatty cells, that work as energy storage and a buffer for the enormous blood pressure that our skin holds from within. The subcutaneous layer is the skin factory. There your body manufactures new skin cells. As the skin cells are produced they migrate upward through the three middle layers of the epidermis. As they do, they get farther and farther away from the blood and nutrients they need to survive. By the time they reach the outside world they are dead. There is nothing left for them to do but flake off so the next hatch of cell ls can arrive.

As skin cells grow and mature, they move up to the stratum cornea, become dry and flat, eventually shedding off. This process is called desquamation. lt takes, on average, about twenty-eight days for a skin cell to travel from the base of the epidermis to become a dry keratinized cell at the top of the epidermis and then be shed at the surface of the stratum cornea layer. When your skin becomes oily, these dead cells stick to excess sebum and form a paste that clogs pores.

When we age, skin cells turnover slows by 50 per cent, which shows up as wrinkles and rough skin surlcace. One inch of skin is formed by 9,500,00 cells so dead cells even being scrubbed off by, say, glycolic peels, do not pose any danger to the consistency of the skin.

Pores
Sit in Front ofthe rnirror and gently pull the skin on your face. You will see lots of tiny dots, pink or black craters that may be ernpty and clean or filled with black substance. A pore consists of a highly coiled secretory portion deep in the dermis, which forms a tiny bulb, and a relatively straight duct conducts the secretions toward the surface of the epidermis.

Pore is a tiny duct in the skin, called a follicle. lf you look at the pore structure, it will look like a rabbit`s hole in the skin. There are two kinds of pore on your face: the openings with hair follicles in them and tiny openings to sweat glands. It is important to understand the difference hetween two kinds of pores because sweat glands and sweat production are not directly linked to acne. That is why you cannot cleanse pores and remove acne-causing blockages (“impurities" or “toxins") either by steaming in a spa, visiting a sauna or vigorous exercise in the gym. The sweat is made by a different gland and emerges onto the skin through a completely dilferent pore.

Another type of pores contains a sebaceous (oil) follicle and sometimes a hair. lnside this “rabbit hole" there is a tiny opening of a sebaceous gland which produces sebum, skin`s nature-given moisturizer. Pore blockages causing acne forrn below these openings, deep inside at the epidermis level.

Pores are a natural part of the skin. Fair-skinned models in glossy magazines may look absolutely poreless and flawless. But before you start examining every back dot on your face please remember:
a) makeup artists spend hours applying foundations on rnudels' faces starting with primers that visilaly reduce the size of pores;
b) people with lighter complexions tend to have more narrow pores;
c) there`s always such thing as Photoshop. Patch it. blur it, and the pore is gone!

Can we shrink the size of our pores? Unfortunately, no. The size of the pore is hereditary, and nothing really can shrink the pore and alter its physical diameter. Your goal is to keep the pore clean and healthy. When you age, your pore openings will deepen. as skin loses its tautness and elasticity. You can also minimize its appearance with various primers and leave-on treatments.

Sweat
Our body produces two types of fluids that cool, moisturize and cleanse the surface of the skin. lf we lived in a perfect world without air pollution, UV radiation and chemically loaded foods, we won’t even need all the complex beauty routine-our skin will cleanse, tone and moisturize itselli maybe with a little help of pure water. The perfectly healthy body rarely needs anything else, but let’s be realistic. Our skin does require a helping hand from outside.

When everything is working smoothly. the oil ducts send their clear lubricating fluid into the hair follicles that dot your skin (even where you have no hair, you have follicles), and the swear glands nearby secrete drops of`sweat.

Sweat is the most noticeable skin fluid. Every day we sweat out about three cups of sweat of our bodies, no matter how cold or hot there is outside. Sweat is a thin, watery substance. Sweat contains approximately 99% water and 1% solids. The solids are half inorganic salt, mostly sodium chloride, and organic compounds, such as amino acids, urea and peptides.

Sweat helps the body to control temperature but sweat glands are also activated by emotions. That`s why we sweat when we are excited or scared! Sweat is also loaded with scented substances that form our unique hody odor signature. Human beings are able to communicate on scent level, just like animals, and the odor depends greatly on the physical condition, emotional condition, and of course on sexual desires. There`s a suspicion that love on the first sight is actually love on the first sniff!

Sweat also lubricates upper layer skin cells preventing them from shedding too quickly, and here it is getting mixed with oil, or sebum, which is produced by another type of glands, called sebaceous.
