Freckles, Sunspots, Melasma and More

Skin color is a manifestation of genetic and environmental factors. The cells have my color of skin known as melanocytes are deterministic. These cells are found throughout the upper layers of the skin and produce pigment granules of melanin. Spread granules of melanin in skin cells known as keratinocytes surrounding and protecting the cells' DNA from damage caused by ultraviolet radiation. Contrary to popular belief, a tan is damage actually does not provide protection from sun and sun.What is hyperpigmentation? Many factors may influence the normal function of melanocytes and cause a number of pigmentation disorders Therefore. Normal, healthy skin color is uniform and free of stains. This stems from the synthesis of a normal amount of skin pigment from melanocytes and its transfer to the outer layers. Exposure to ultraviolet radiation, inflammation, hormonal changes, medications, acne, skin diseases and genetic predisposition may increase the production of melanin pigment and cause brown spots to appear on the skin. This is called hyperpigmentation.Hyperpigmentation can affect the skin color of people of all races. What are the different types of hyperpigmentation? Freckles are small brown spots that can appear anywhere on the body but are most commonly seen on the face and arms and other sun exposed areas. Freckles are most common in fair skinned individuals due to exposure to the sun. Therefore, they can also occur in children. Freckles are most important in summer, but will fade in the winter as old skin cells are shed and replaced by new ones.Sunspots, age spots, or 'liver' points are a very common form of hyperpigmentation. They are basically collected surface layer melanin that accumulate in the upper part of the skin. Sunspots occur as a result of cumulative sun damage over several years. They appear as small dark spots that are commonly seen on the backs of the hands, legs and face or other areas that are exposed to the sun. In contrast with the freckles, which persist for long periods of time and not fade in the winter months. It is very important to distinguish the harmless sunspots melanoma early. If the stain is new, contains more than one color or with irregular borders or if in doubt, consult a dermatologist.Melasma is more common in women but not men, about 10% of patients. And 'more common in people with brown skin or black or Asia, the Middle East, India and South America. Melasma is similar to age spots, but tends to involve larger areas. The lesions may be well defined or are irregular, so called, geographical boundaries and usually appear on the central part of the face opposite the lip, nose, chin and upper melasma is precipitated by hormonal changes as seen in pregnancy, exposure to the sun and with the use of certain drugs tested oral contraceptives, anti-seizure and anti-malarial drugs. Post-inflammatory hyperpigmentation is usually a problem for individuals with darker develops as a result of irritation or injury to the skin skin.It as seen with acne, psoriasis, eczema and trauma. Dark areas on the skin are limited to the site of inflammation and more indistinct, feathered edges. Skin in this condition, the pigment cells tend to be deposited melanin in both layers of the superficial and deep. How is hyperpigmentation treated? The successful treatment of hyperpigmentation should include the daily use of sunscreen. Freckles, age spots, sun spots and other dark skin may become darker and more pronounced when skin is exposed to. This happens because melanin absorbs the energy of the sun's harmful ultraviolet rays to protect skin from overexposure. This process darkens the areas that are already hyperpigmented. Therefore, it is essential to use of sunblock mat that contains titanium dioxide every morning and / or zinc oxide. The light in the visible spectrum, can dark pigment. Even with the highest SPF sunscreens are not effective in blocking the visible radiation. A single day of excess sun exposure can undo many months of treatment for pigment brighten and fade darkened skin patches disorders.Bleaches slowing the production of melanin. Prescription creams that lighten the skin contain hydroquinone. The whitening of the skin can be a long and painful process. Therefore, to obtain faster results, hydroquinone was found to be more effective in combination with other agents. These products include alpha hydroxy acids and skin tested as glycolic acid, mandelic acid, vitamin A derivatives tested as Tazorac and Retin-A and vitamin C. Even alone, these agents may help to eradicate discoloration as well as exfoliate the discolored spots. Pigmented lesions can be treated with mechanical agents that exfoliate the skin as microdermabrasion investigation and / or erbium lasers that vaporize the skin. Exfoliation and vaporization surface to remove the pigment cells, and then the penetration of bleaching agents Facilitate. Finally, treatments of pulsed light capable of treating pigmented lesions in an effective and precise. Selectively light is used to direct the pigment without damaging the surrounding normal skin. [EXTRACT] The skin color is a manifestation of genetic and environmental factors. Determine the cell, the color of the skin are called melanocytes. These cells are generated in the upper layers of the skin and the melanin granules. Melanin granules statement issued in surrounding cells, as keratinocytes and protect cells from DNA damage caused by ultraviolet radiation. Contrary to popular belief, a tan is actually sun damage and provides no protection against sun.What is hyperpigmentation? Many factors may influence the normal function of melanocytes and thus a large number of diseases pigment. Normal, healthy skin is a uniform color and free from blemishes. This derives from the synthesis of a normal amount of the pigment of melanocytes and their transfer to the outer layers of the skin. UV exposure, inflammation, hormonal changes, medications, acne, skin diseases and genetic predisposition may increase the production of melanin, causing dark pigmented spots appear on the skin. This is called hyperpigmentation.Hyperpigmentation skin color of people of all races concern. What are the different types of hyperpigmentation? Freckles are small brown spots that can appear anywhere on the body but most commonly on the face and arms and other sun-exposed areas can be seen. Freckles are most common in fair-skinned people due to exposure to the sun. Therefore, they can also occur in children. Freckles are most important in the summer but in winter to fade like the old skin cells shed and replaced by new ones.Sunspots, age spots, or "liver" spots are a very common form of hyperpigmentation. Are generally harvested surface of melanin which to accumulate in the upper layer of the skin. Sunspots occur as a result of cumulative sun damage over several years. They appear as small dark spots, which are often seen on the backs of the hands, legs and face or other areas that are exposed to the sun. Unlike freckles, which persist for a long time and disappear in the winter months. It is very important to distinguish the harmless sunspots melanoma early. If the site is new, contains more advice if in doubt, as a color or an irregular border or a dermatologist.Melasma is frequently observed in women, but about 10% of patients are men. And 'more common in people with brown skin or black, or Asia, the Middle East, India and South America. Melasma presents itself as age spots, but tends to involve larger areas. The lesions can be precisely defined or irregular, the so-called geographical limits and which is typically observed in the central part of the face forehead, nose, upper lip and chin. Melasma is seen by hormonal changes during pregnancy, such as sunlight and the use of certain drugs such as oral contraceptives, anti-seizure and anti-malarial drugs. Post-hyperpigmentation is usually a problem for people with darker skin.It develops as a result of injury or irritation of the skin such as acne, psoriasis, eczema and trauma seen. Limited, the dark spots on the skin at the site of inflammation and more indistinct, feathered edges. In this state, the cells of the pigment melanin, which tend to the surface layers and deep skin for storage. How hyperpigmentation treated?

This happens because melanin absorbs the energy of the sun's harmful UV rays to protect skin from overexposure. This process darkens the areas that are already hyperpigmented. Therefore, it is important to use a solar mat every morning, the titanium dioxide and / or zinc oxide. Light in the visible spectrum pigment darkening. Moreover, sunscreens with the highest SPF is not effective in blocking the visible radiation. Make a day of excess sun can undo months of treatment for many disorders.Bleaches pigment brighten and fade dark spots on the skin by slowing the production of melanin. Prescription creams that lighten the skin contain hydroquinone. The whitening of the skin can be a long and painful process. Therefore, in order to obtain more rapid results, it has been found to be hydroquinone, which in combination with other agents. These products include alpha hydroxy acids such as glycolic acid and mandelic acid, vitamin A derivatives such as Retin-A and Tazorac and vitamin C. Although these agents alone can help remove stains and discolored spots exfoliate the skin. The pigmented lesions by mechanical means, that the skin such as microdermabrasion and / or erbium laser to vaporize the skin peeling to be treated. Remove peels and superficial pigmented skin cells evaporation and facilitate the penetration of bleaching agents. Finally, treatment of pulsed light to treat pigmented lesions effectively and accurately. The light is intended to the pigment without damaging the surrounding normal skin selectively.
