One of the great scientific mavericks of this century spoke at LBL August 10, 1993 at a special seminar hosted by the Life Sciences Division’s Lipoprotein and Atherosclerosis Group. Linus Pauling, two-time Nobel laureate and the world’s foremost vitamin C proponent, entertained an overflow crowd in the Bldg. 66 auditorium with a talk on Vitamin C and Heart Disease.

The lively 92-year-old first gave a candid history of how he came to take up the vitamin C cause. He was introduced to the subject by biochemist Irwin Stone in 1966. Five years later, he would pen “Vitamin C and the Common Cold,” and then boldly go on to champion vitamin C as a fighter of more serious diseases such as cancer.

According to Pauling, the vitamin’s versatility in illness prevention arises from its role in the manufacture of collagen, the protein that gives shape to connective tissues and strength to skin and blood vessels.

One of the great misfortunes of human evolution, Pauling explained, was when our human ancestors lost their ability to manufacture vitamin C. Pauling thinks the trait was probably discarded at a time when our ancestors had a diet of vitamin-rich plants and didn’t need to produce the vitamin themselves. This left today’s primates (including humans) as one of the few groups of animals that must get the vitamin through the diet.

Ever since proto-humans moved out of fruit-and-vegetable-rich habitats, Pauling said, they have suffered great deficiencies of vitamin C. Pauling has forthrightly recommended that people make up for this deficiency with daily doses of vitamin C much greater than the 60 mg generally recommended.

He said our vitamin C consumption should be on par with what other animals produce by themselves, typically 10-12 grams a day. Pauling practices what he preaches, having gradually upped his daily doses of vitamin C from 3 grams in the 1960s to a hefty 18 grams today.

Pauling went on to discuss vitamin C’s connection with lipoprotein-a, a substance whose levels in the blood have been linked to cardiovascular disease. Lipoprotein-a is also a major component of the plaques found in the blood vessels of atherosclerosis patients.

Pauling has published studies asserting that lipoprotein-a is a surrogate for vitamin C, serving to strengthen blood vessel walls in the absence of adequate amounts of the vitamin in the diet. In the lecture, Pauling noted that animals which, unlike humans, manufacture their vitamin C and have much higher levels of the vitamin in their bodies, have very little lipoprotein-a in their blood.

Pauling is convinced that doses of vitamin C can help prevent the onset of cardiovascular disease, inhibiting the formation of disease-promoting lesions on blood vessel walls and perhaps decreasing the production of lipoprotein-a in the blood. Vitamin C’s link to healthy blood vessels, Pauling said, is further supported by studies of scurvy, the disease caused by vitamin C deficiency. Fifty percent of patients who die of scurvy, he said, do so because of ruptured blood vessels.

Pauling won his first Nobel Prize in Chemistry in 1954 for using quantum mechanics to elucidate the nature of chemical bonds. He garnered a Nobel Peace Prize in 1962 for his efforts to stem nuclear weapons proliferation.

The scientist founded the Linus Pauling Institute in Palo Alto, where research on vitamin C and other nutrients continues today.

Our skin naturally makes protective oils, which are the most abundant on the face and mid section of the body, and less abundant on the arms and legs. Since our hands and arms have much less of this natural protection, and are the areas most likely to come in contact with the elements, the hands are the most common areas that get dry skin and winter itch.

If we follow a few simple rules, most cases of dry skin can be prevented. I see many patients in the area who could have easily prevented a visit to the dermatologist by following these simple rules:

1. No hot showers or baths:

- Limit your bath/shower to no more than 10 minutes per day.

- Take tepid showers. That means, if there is steam on the mirror, your shower is too hot, and lower its temperature.

- Try to shower at night, and not in the morning, when your body is colder, and you are more likely to warm up with a hotter shower.

2. Use mild soaps.

- Use unscented mild soaps like Dove unscented or Oil of Olay

- If you can, use liquid body washes, which are less drying. Examples are Oil of Olay body wash.

- Do not soap areas that rarely get dirty, like the elbows and knees; a simple rinse with tepid water will suffice.

3. Moisturize your skin:

- If you take baths, add some bath oil to the water.

- Your skin cells are the most hydrated after a shower/bath, however, since the soap you used has washed away your natural oils, the water in your skin will quickly evaporate, and leave you dryer than before. Therefore, you can trap the moisture in your skin by moisturizing. The best moisturizer is simple petroleum jelly, like Vaseline jelly or SBR-Lipocream. Just apply a generous amount to your skin after a shower/bath and use a washcloth to wipe away the excess.

- During the day, use humectants creams on your hands. Humectants bring moisture to your skin. One example of an over the counter brand is AmLactin cream.

The above hints will help prevent dry skin from becoming a more persistent rash. Always remember to see your doctor if you have an ongoing rash, which might need to be treated with prescription ointments. Dr. Memar, a dermatologist, is an active Clinical Assistant Professor at Northwestern University, and medical director of Academic Dermatology & Skin Cancer Institute. A dermatologist is a medical sub-specialist who addresses the health and disease of skin, hair, nails, and mucosa.

A dermatologist is an expert in the anatomy, function, surgery and pathology of the skin. They are uniquely trained in clinical medicine, tissue pathology and surgery pertaining to the skin. Today, dermatologists are in the forefront of medical research, clinical practice, and surgical innovation having to do with the health and beauty of skin.
