The structure of skin
The skin is one of the biggest organs on the body. It has two main layers -
the epidermis and the dermis.
This is the outer surface of the skin that we can see and feel and where we
find the hair follicles. It is made up of several layers that, together, form a
protective outer sheath. This is protected by a mixture of water and oil (sebum)
excreted from the scalp. The mixture is mildly acidic and contains 'friendly'
The epidermis is contstantly being worm away in a process called exfoliation.
Dead cells are shed from the skin and new, healthy cells take their place.
This is the deep, inner layer of the sking that contains the blood and nerve
supply. On the scalp, the dermis contains the sebaceous glands that produce
sebum and the sudiferous glands that produce water. The oil and water mix
together to form a protective covering for the hair.
The dermis also contains nerve receptors that sense heat, cold and pain and
adipose tissue or fat cells.
Features of skin
The skin has a number of features. Most of these grow from the epidermis down
into the dermis. The main ones are:
  • follicles - pore-like structures that produce hair
  • dermal papilla - the origin of all cell growth and cell division
  • sebaceous glands - secrete oil called sebum that protects us against
  • bacteria, lubricates and waterproofs the skin and, on the scalp, makes our hair
    soft, shiny and pliable
  • sudoriferous (sweat) glands - excrete waste in the form of sweat, which
  • evaporates to cool the body
  • arrector pili muscles - attached to the hair follicles, these contract when
  • we get cold. This pulls the hair upright, giving us goose pimples and trapping
    warm air aForma rotunda our body to help keep us warm.
There are four main functions of the skin:
  • protection from strong sunlight and bacteria
  • sensation through the nerves
  • excretion of waste and oil to make us waterproof
  • regulation of temperature by releasing sweat to cool us and trapping air
  • aForma rotunda us to keep us warm
The natural pigment of the skin is the same as the pigment in the hair. It is
called melanin and is produced by cells called melanocytes.

Woman is certainly you may experience the following problems and did not know how to fix them. So which 2 comes to help and propose some simple solutions:

Bags under the eyes and dark circles

These two problems often come hand in hand, the result of poor circulation. "The bags are some accumulation of fluids that gather and do not move through the lymphatic system, and circles indicate clearly an inadequate circulation of blood," says Jennifer DiFrancesco, director of spa in California.

Genetics has a very big role in the occurrence of these problems, but as much matter and nights spent in front of computer. Other possible culprits are alcohol, food too salty and allergies. In addition, stress, eating a low nutrient or inflammation of the nasal area can weaken blood vessels.

DiFrancesco says it's good to give yourself a massage around your eyes every night, applying a cold gel instead of cream, if you have fluid buildup. Find ingredients such as green tea or vitamin K, this strengthening vessels, while marigolds and chamomile reduce inflammation. Apply the gel using a finger and massage in a clockwise direction, but not press very hard, because the skin in that area is extremely delicate.

Put 2 cups of water to boil and add green tea, and after 5 minutes remove the tea bags and allow the liquid to cool. When it reached room temperature, pour it into ice cube and put it in the freezer. Squeeze excess water from the bags and dark circles keep them on 10 minutes. Regarding the frozen cubes, they will be better in the morning when you wake up tired face.

Nose, chin and forehead, also known as the T-zone, have glands that secrete more oil than any other part of the body. So, if you have oily skin, you should take care of this area, especially around the menstrual cycle. Because the pores on the nose are usually larger than the rest, this happens mostly blackheads because of the accumulation of sebum, dead cells and bacteria. Hormones trigger rash in the chin area, especially when you're pregnant, you have an irregular menstrual cycle, you are premenopausal or taking birth control pills without consulting your doctor.

"This is because of increased estrogen levels," says Zoe Picayo esthetician in New York. You need to exfoliate in regularly using slightly abrasive products, two or three times a week. Be careful not to choose something too hard and not dwell too much when you do, because you do not want to scratch the skin.

In addition, careful what objects come into contact with the girl and that they are as clean. The mobile phone, for example, may bring many bacteria in the cheeks.

Put a little baking soda powder in hand, moisten it with water and apply it on the face, massaging gently. It is one of the best natural methods of exfoliation.

In addition, apart from external factors, breakouts and the chin may suggest a problem with the digestive system when you consider Chinese medicine.
