Since the nature of the skin tend to acidity, the addition of an alkaline substance or even moderat

This measure on behalf of the exponent Alheidorjina known. English and knows the two letters they write in the following way: pH. The first character writes a small and a large second. The two characters are the abbreviation of two words: Potential Hydrogen. A digital scale starts from No. 0 to 14, and 7 represents a moderation between acidity and alkalinity. Lower the number 7 has increased acidity. The higher the number increased from 7 increased alkaline. The battery acid, lemon juice and vinegar from sour materials, while considered ammonia and bicarbonate of soda from alkaline materials.
While be healthy skin, the pH range between 4.5 and 6.5, which means that the skin tends more alkaline antacid, and it is not moderate. This feature is called "Acid Mantle of the skin," or in English - acid mantle - a product of many things, such as secretions of various glands and skin secretions also bacteria naturally corning present on the surface of the skin. (1) This abaya play an important role in maintaining the skin, such as kill harmful bacteria. (1) so that scientists recently discovered that acne affects the skin was alkaline, and when he addressed the skin even more than acidity, corning this helps to cure acne. (2)
Since the nature of the skin tend to acidity, the addition of an alkaline substance or even moderate skin resulting in a defect in the work of the skin cells, which leads to dry and weak resistance to bacterial infections. Study has shown that washing the skin alkaline substance - like normal - soap lead to this imbalance, even after just one use, and that this imbalance increases cumulatively corning with each use. Of course, this flaw affects more than suffering from skin diseases such as eczema and psoriasis, and also affects the elderly, this is because the skin of this group of the foundation of the problems, which are inherently weak skin will not be able to withstand these attacks.

But when we add acidic substance to the skin, the result varies depending on the pH of the additive on the skin. As we said Valepeshrh inherently tend to acidity or alkalinity for moderation (but the pH of the skin is weak and not strong acidity). If we add material is also weak acidity, this skin will be happy, because it helps them do their part and help to keep the moisture and freshness and strengthens. (4) But the problem occurs when we add material pH strong. Let's take an example of a lemon.
Lemon is used by many people to direct the skin in an attempt to get the white skin net. And lemon citrus fruit contains citric acid or citric acid. It is the fruit acids known to be used for peeling corning skin, such as lactic acid or acid Algelaekolec - lactic acid or glycolic acid - and the use of these acids in peeling back the skin rejuvenated and fit what spoil exposure to sunlight. But it must be cautious, corning factor is the pH in citric acid up to about 2 or 3, and this means that it may lead to inflammation of the skin and makes it more sensitive to the sun and also increases the likelihood of discolored. This means that the use of lemon directly on the skin is not a good idea, but that was part of a cream suit acidity of the skin, then the skin will benefit too.
4. always advisable to use a dedicated lotion for washing the face and not just ordinary soap, especially for sensitive skin. Most lotions on the market taking into account the acidity of the skin. As a general rule - if lye cause dry skin or itchy or sensitive skin or a feeling that the "tight", it is not appropriate lotion and must search for a new lotion.
Note: The contact with the skin to severe alkaline materials corning or severe acidity lead to chemical burns. But since we do not discuss such a high degree of acidity or alkalinity, but we discuss regular grades of human exposure in skin products, the chemical burns will not be discussed corning in this article will be devoted corning to an article at a later time.

Welcome to Madame Nermin no need to try to determine the type of skin As I mentioned in the article is that the nature corning of the skin that tend to be slightly acidic. Therefore should corning not should use ordinary soap to wash your face because ordinary alkaline soap and is therefore not suitable for our skin brackish acidity. And it is better to use a dedicated Face Lotion. The lemon, it should not be used directly on the skin under any circumstances, because it is very acid may harm the skin. As if it was part of the mix I do not mind as long as the use of other substances in the mixture is harmless. I hope that I have succeeded in clarifying the idea and I welcome any questions you may have. Reply Delete
I explained my doctor, a thousand thanks, I really do you Besat the lye Ptai Mavhmich need of written data if it is possible Houdrtk Tajabila image of the components of any lotion and any needs who cared omitted and associating possible ..;) Reply Delete corning
Madame Nermin. Indeed many components and difficult to save you a useful and which are harmful. As a general rule if lye makes your skin is dry or sensitive or (tight) or the itch, it is inappropriate and should be changed. Look for sensitive skin dedicated lotion, lotion corning or written him that he keeps the acidity of the skin, such as the word "pH balance" as there are good companies such as lotions Clean and produces corning Clear Neutrogena Dove Olay luck!
