Dry Skin - II
Wednesday, September 9th, 2009
Dry skin is not as simple as lack of moisture. When dry skin occurs the intracellular matrix (the substances between skin cells that keep them intact) has become depleted or damaged, creating water loss. In order to prevent dry skin, the primary goal is to reduce the damage to, as well as preserve and enhance, the intracellular matrix.
To reduce damage to the skin’s matrix, never use drying skin-care products such as soaps, harsh cleansers, or products with irritating ingredients. These problematic products can disrupt the outer layer of the skin, destroying the intracellular matrix and eventually causing flakiness and roughness.
Constant exposure to arid environments, cold weather, as well as dry, low humidity air can destroy the skin’s matrix.
Sun damage plays a major role in why skin becomes dry any time of the year. Unprotected sun exposure creates a damaged outer layer of skin where skin cells adhere poorly to each other. The result is that the surface of new skin being formed is continually unhealthy and impaired. Sun damage also disrupts and destroys the skin’s intracellular matrix. Every day of the year,the skin is subject to sun damage. Keep in mind that the sun’s damaging rays come through office and car windows. Daily sun protection is vital to the health of skin.
Improving cell turnover is another important consideration in getting rid of dry skin and improving its appearance. Dry skin does not shed as it should and those built-up layers of dead skin cells can feel rough and cause skin to look flaky and dull. A well-formulated, pH-correct exfoliant such as an alpha hydroxy acid (glycolic or lactic acid) or beta hydroxy acid (salicylic acid) can handle this problem.
Genetically, aged skin is also a cause of dryness, because as the body’s levels of estrogen drop the skin becomes thinner and the fat deposits under the skin (part of the skin’s protective barrier) also become thinner or depleted altogether. Regrettably, there is little that can be done about this other than using various types of hormone replacement therapy (HRT) and plant-based hormone replacement (phytoestrogens) that can be consumed when eating or drinking soy-based foods.
By the way, while drinking eight glasses of water a day is great for your body, it doesn’t work to improve or reduce dry skin. If all it took to get rid of dry skin was drinking more water, then no one would have dry skin and moisturizers would stop being sold. The causes of and treatments for dry skin are far more complicated than just drinking water.
Here are some options to deal with dry skin:
1. Daylight causes skin damage, which means it slowly becomes less able to hold moisture or feel smooth.
2. Moisturizers should be filled to the brim with antioxidants, water-binding agents, and anti-inflammatory ingredients. If you have persistent or exceptionally dry skin, the moisturizers you use should also contain various forms of lipids such as lecithin, cholesterol, glycerol, glycerides, and plant oils.
3. Apply and reapply moisturizer. Whenever your skin starts feeling dry, put more on. It is also important to be diligent about reapplying moisturizer every time you wash your hands.
4. Avoid soap—use only gentle, nondrying cleansers. Never use a cleanser that leaves a dry feeling on your skin. Do not overscrub skin—you can’t scour away dryness.
5. Avoid soaking in the bath tub, or long showers. Water can be bad for skin because it breaks down the skin’s protective covering (the skin’s intracellular matrix) destroying the substances that keep skin cells intact. Keep showers or baths as short as possible.
6. Get a humidifier, low humidity is the cause of most weather-related dry skin, whether it is winter or a desert environment.
7. Don’t forget your lips, they are the least capable of staying smooth and soft when the air becomes dry. They lack the lipids and cell structure the rest of the face has and, as a result, are far more vulnerable to the effects of dry air. During the day apply and reapply an emollient lipstick or gloss. At night be sure to do the same.
8. Never use products that contain drying or irritating ingredients.
