Understanding Skin Care

The skin serves numerous functions - detoxifying, protecting, regulating - but the primary protective or barrier function is the most obvious. The top layer of skin cells has the most important function in maintaining the effectiveness of the barrier. Here the individual cells overlie each other and are tightly packed, preventing bacteria from entering and maintaining the water-holding properties of the skin.

Fatty substances (lipids) are secreted by the cells during the course of their journey from the base layer of the skin to the top. These lipid molecules join up and form a tough connecting network, in effect acting as the mortar between the bricks of a wall.

The cell wall barriers are simply layers of fats that surround the watery contents. Therefore, the communication mechanisms must operate through these fatty cell walls. In fact, many of the substances that are involved in this communication process are various fats since it is easiest for fats to move within the fatty layers that comprise the cell walls. Despite its bad reputation, proper fats and cellular fats are of major importance in our body’s biochemistry and physiology.

Damage to the skin barrier can result from a combination of genetic predisposion and exposure to sensitizing chemicals and other substances. That is why avoiding irritants is as important as using products that help. In skin care, the most common irritants are usually perfumes and preservatives.

Fatty substances control the majority of our body’s physiology through receptors that activate many important genes. Likewise, our skin barrier is comprised of a supporting structure of collagen, a protein that contains fats that serve a critical function. These fats prevent the excess loss of water through our skin and prevent the cells of our body from becoming dehydrated and dying.

A major sign of a defective skin is the dryness that results from excessive water loss. This water can not be applied topically but must be ingested. To prevent the excessive water loss and the resulting dry skin, we must repair the skin barrier. We find that the skin composition in individuals with dry skin is due to an improper mixture of the skin fats. This is commonly due to a deficiency in our diet of the correct fats, those contained in natural olive oils, avocados, and healthy nuts, etc. On a nutritional basis, we can provide these necessary fats through the skin sometimes through topical treatments containing natural butters or oils, like Shea, olive and cocoa butter. The epidermis is not a usual means to acquire nutrition but it can absorb enough fatty substances to correct the fat imbalances that are the cause of the defect in the skin’s barrier function and thus correct the dry, itchy skin or sensitive skin problem. Try to be aware of chemical preservatives in any topical products you do use.

Dry skin recommendations and supplements

Dry skin recommendations and supplements that can help your skin

Dry skin responds best to climates with high humidity and hates cold, dry and windy climates. Indoor heating and air-conditioning can also be drying to skin. If you live in a dry climate, try to use a humidifier to add moisture to the air. There are many affordable varieties available on the market or for re-sale today.
Don’t steam facials because steaming is actually more drying than hydrating. Likewise, avoid steam rooms, swimming pools, chlorinated hot tubs and overly hot baths. Avoid those old-fashioned recommendations to put your face under a towel over a pot of boiling water. Not only will this lead to excessive drying, it can also cause broken capillaries or blood veins along the fragile skin of the cheeks and nose.

If your skin tends to be dry, and tight or wrinkled and sun spotted, avoid excessive sun, exposure or hot wax facial treatments, hair sprays and hair dyes that can dry your skin and provoke inflammation leading to dark spots.

Hormone replacement therapy can help to lessen skin dryness after Menopause though it will increase age spots due to new hormones stimulating pigment production. It may help prevent the wrinkles that quickly occur after menopause Consult with your doctor with your family health history to make an informed decision on HRT.
