    There are four epidermal layers, the first of which is the stratum corneum. When you touch your skin, what you're feeling is almost thirty layers of dead keratin cells (a protein that also makes up hair and nails). All these inert cells, called keratinocytes, overlap like thin shingles on a roof, with pores (the...Read More

    Monounsaturated fats are found in olive oil, canola oil, and avocados. These healthy fats help to maintain the water level in the epidermis and supply the ceramides and fats that keep the bricks and mortar of the skin healthy and intact. This translates into less itchy, healthy-looking, glowing skin. Read More

    Biotin is found in egg yolks, brewer's yeast, bananas, lentils, cauliflower, and salmon. This B vitamin strengthens skin, hair, and nails. (A deficiency is extremely rare because bacteria in your intestines make all the biotin you need.) A deficit can lead to hair loss or dermatitis (itchy, scaly skin). Some...Read More

    Melanocytes have the crucial job of producing melanin, the pigment that absorbs ultraviolet light from the sun. Ultraviolet wavelengths can damage or destroy the DNA in cells, causing mutations that can turn into cancers. Once the skin is exposed to sunlight, the melanocytes try to cover all the cells with melanin,...Read More

    Vitamin A is found in fish oil, salmon, carrots, dairy products, spinach, and broccoli. Since it promotes normal keratinization (the turnover of skin cells), it helps with conditions such as acne, eczema, and psoriasis. Without it, skin becomes extremely dry and dull. It's important to note that if you...Read More

    Ellen Marmur, MD answered:
    Every cleanser contains a surfactant, which emulsifies and washes debris and oil from the skin. This may seem obvious, but their names are not. Sodium lauryl sulfate is a stronger detergent and sodium cocyl isethionate is mild. We've always heard that the more cleanser foams, the more drying it will be, and that's...Read More

    Ellen Marmur, MD answered:
    Like most scars, the byproducts of acne are generated by trauma to the skin that leads to abnormal collagen formation. Just imagine how much trauma the epidermis and the dermis goes through with acne: all that bacteria and those toxic free fatty acids destroy collagen, and the new collagen being...Read More

    These antioxidant vitamins fight oxidation damage in skin cells' DNA. Because they are key elements in the structural proteins in the body, they are important to the integrity of the blood vessels and hair follicles. They're required for the formation of collagen, and medical studies have found that they...Read More

    FRIDAY, Sept. 19, 2014 (HealthDay News) -- U.S. military troops deployed to sunny climates may have an increased risk of skin cancer, according to a new study.

    Ellen Marmur, MD answered:
    The food you put into your mouth has an effect once it's been metabolized and delivered to the skin. The way it is metabolized is also why eating certain foods, though beneficial to both the skin and body, may not affect the complexion directly. The body breaks down what we eat into tiny particles of proteins, fats,...Read More

    A broad-spectrum body lotion with an SPF of 15 is better than nothing but not as protective as the broad-spectrum sunblock (with the harder-core sunscreens and blockers) that you might wear poolside. Most daily moisturizers with SPF add one or two chemical sunscreens and maybe one chemical UVA blocker (remember...Read More

    Ellen Marmur, MD answered:
    In general, look for a broad-spectrum product that protects against both UVA and UVB radiation. (UVC wavelengths are much shorter, and don't penetrate the atmosphere.) A facial lotion that contains one or two chemical sunscreens and at least one sunblock (titanium dioxide or zinc oxide) is perfectly adequate....Read More

    Ellen Marmur, MD answered:
    Just beneath the Gore-tex of the stratum corneum lies the brick wall of the epidermis. The "bricks" are squamous cells (durable keratinocytes that will eventually move up to the stratum corneum and be sloughed off) held together with rope-like bridges. The mortar is filled with fatty ceramides, which act as glue between the cells....Read More

    It's important to realize that skin does not exist in a vacuum. The way it reacts is tied to everything in your life. If you wake up and have pimples, you need to ask yourself, "Am I under stress?" "Did I eat something strange?" "Am I getting my period?" To evaluate what kind of skin you are having (and...Read More

    Wildly fluctuating hormones during pregnancy can create an awful complexion or a radiant glow, often in the same woman. For the first twelve weeks, the growth hormone human chorionic gonadotropin (HCG) surges to prepare the placenta and increase the blood volume in the body. (This can create a flushed, healthy complexion...Read More
