BIO SKIN CARE

Treatments and skin care

The skin is our body wrapping. It is a vital organ the largest of all that modulates body temperature, protects the viscera and opposes the passage of infectious organisms.
It also nourishes the body by converting sunlight into vitamin D.
Creams and lotions to exfoliating (peeling) chemical, a range of products and processes intended to reduce wrinkles and rejuvenate the skin before us.
Some of the most costly preparations are harmless, but they offer little real benefit, others may do more harm than good, especially in people with sensitive skin.
Therefore, better learn a little about the products we buy.

Moisturizers

Despite all the care that is put to protect their skin from the sun, it will eventually dry out and shrivel with time. Dermatologists recommend using a moisturizer every day to counteract the aging of the skin.
In reality, these products hydrate not skin, they rather help to preserve the natural moisture. (This is one reason why it is important to drink plenty of water for six to eight glasses a day.)
Better result is obtained by applying moisturizer after showering or bathing while skin is still damp.

How to choose a moisturizer?

Lotions that contain lanolin or petrolatum take longer and are best for very dry skin but can cause allergic reactions.
Some people are also too thick.
On a normal to dry skin, use a lotion based light oil.
People with oily skin should also use a moisturizer, provided it is water-based (the words “oil free” should appear on the label).
In the presence of acne, you should choose a non-comedogenic, will not clog pores. Finally, we must remember that more expensive does not always mean better.
Often, the price is more in packaging and marketing to product efficacy.
In contrast, the most expensive brands may contain the finest ingredients. It should first choose the product that will deliver the best results.

Masks

Masks match more luxury than science.
They clean the pores and may promote a transient increase in [blood flow to the face, which provides temporary skin looking younger.
They have no lasting effect on wrinkles and skin dryness.
Abrasive masks, even those so-called natural, can injure the skin by exfoliating too brutal.
The skin naturally loses millions of cells every day.
Excessive exfoliation may cause various complications sensitivity, scaly plaques, grayish coloring of the skin.

Retin-A

Retin-A and Renova are two brands under which is offered a prescription drug called tretinoin, prepared from a derivative of vitamin A.
Tretinoin has been launched on the market in 1971 as an agent against acne.
It was later discovered that removes fine wrinkles and fine lines.
It exerts this effect by exfoliating the epidemic and by stimulating production of collagen in the dermis.
Although Retin-A and Renova can improve the texture and general appearance of the skin, it is not proven to eliminate wrinkles and deep hollows.
Moreover, they can dry the skin and cause a burning sensation or tingling passengers.
Abuse sometimes causes redness, scaling and inflammation.

Tretinoin also increases skin sensitivity to sunlight.
We must therefore apply a sunscreen before going out when using this drug.

Alpha-hydroxy

Alpha-hydroxy acids (AHAs) are acids derived from fructose or lactose.
It is said they give a more youthful skin.
Is this the case?
Yes. Like tretinoin, AHAs exert a peeling effect and shorten the time for regeneration of skin cells. It is not proven to stimulate collagen production, which is the case of tretinoin.
Some lotions and creams have a higher content than other AHAs.
As required by the cosmetics industry, the AHA content of all OTC products will be limited to 10% or less.
Some of the creams available commercially have content AHA about 2 or 3%.
They may have a peeling effect, but less deeply penetrate the skin as creams containing AHAs more.
The content of an AHA lotion should be 5 to 10% (If the percentage is not indicated, the AHA
should be among the first three ingredients.
Several terms refer to the AHA: Glycolic acid, lactic acid, malic acid, citric acid, etc.).

Some creams prescribed by dermatologists have a higher content of AHA (and higher pH, to counter the irritation).
Products containing high levels of AHA should be used with caution and only under medical supervision.
Such as cosmetics with AHAs are widely available since 1992, their long-term effects are unknown, but some kind of adverse events were reported: strong redness, edema (especially in-
around the eyes), burning, blistering, bleeding, rash, itching, skin discoloration, etc..

Using Alpha-hydroxy

• The cosmetic industry address the following guidelines for people using the AHA.

• Protect your skin while outdoors. Use a sunscreen with an SPF of 15 or higher and wear a wide brimmed hat.

• Buy products whose label is self-explanatory. The ingredients and the name and address of the manufacturer must be included. AHA content and pH can be provided (not required). AHA content of 10% or less and a pH of 3.5 or above reflect the recommendations of the industry in safety.

• Try the product on a small portion of the skin when first applied. Stop using the product in case of adverse reactions (burning, tingling, redness, etc.)..

• Follow the instructions, use the recommended amounts and keep the products out

of reach of children.

Like tretinoin, AHAs make the skin more sensitive to sunlight

For people that meets light exfoliation, the simplest solution may be to use a friction glove loofah, sponge or scrub rough granular.
All are effective if used carefully and with sufficient water to avoid excessive friction.
In general, mild synthetic granular scrubs are safer than many natural exfoliants, whose irregular grains can irritate the skin.

Exfoliation (peeling) chemical

The chemical peels, performed by a dermatologist or plastic surgeon, is to apply a skin product with a high concentration of AHA (up to 70%).
The product penetrates the skin to the dermis.
The chemical peels may be more effective than creams with AHAs, but it can cause pain, swelling, burns and infection and scarring.
The skin takes up to two weeks to heal and up to three months to regain its natural color.
Two other techniques, dermabrasion and laser resurfacing, can remove the entire epidemic and various parts of the dermis through a process called microponçage.
They are usually performed to remove acne scars or fine wrinkles around the mouth beyond. Recently, laser resurfacing has replaced dermabrasion as a technique the safest and most effective.
Skin subjected to dermabrasion may remain pink for approximately three months, and we often advise patients to use sunscreen and non-allergenic makeup during the 6 to 12 months after surgery.
Dermabrasion and laser resurfacing are not infallible, and more than one treatment may be necessary to remove deep acne scars.

Biosafety

The skin products have their limitations, it is easier to prevent skin lesions that heal. Up to 90% of skin lesions are due to prolonged exposure to sunlight.
Sunscreens filter out UVA and UVB rays are the best defenses.
He should wear a wide brimmed hat and avoid the sun between 10 and 15 hours.
A balanced diet, regular exercise, adequate sleep, non-smoking, moderate alcohol consumption and body weight stability also contribute to skin health.

Age spots

Age spots have little to do with age.
These minor changes in pigmentation of the skin are caused by sunlight and appear often in people with fair skin.
A bleaching cream may fade, but the laser is more effective.

A spot is probably a spot of old age if:

* It appears on the front or back of the hand
* It is yellowish, tan or light brown
* Color is united (age spots can be round or irregular in shape and have the size of a freckle or a button overcoat)
* It does not, is painless and does not change color (ie, it must be examined by a doctor).
