Topical vitamin C is a science-backed, dermatologist-favorite ingredient that may help slow early skin aging, prevent sun damage, and improve the appearance of wrinkles, dark spots, and acne. Vitamin C is an antioxidant, meaning it fights harmful free radicals (toxins) that come in contact with your skin from external sources like air pollution, or from inside the body as a result of normal processes like your metabolism. Free radicals can damage the skin, and applying topical vitamin C can combat free radicals and may improve the skin’s overall appearance. Skin benefits of vitamin C A few clinical studies have demonstrated that vitamin C can improve wrinkles. One study showed that…

In the US, breast cancer is the most commonly diagnosed cancer in women, and the second leading cause of cancer-related deaths. Each year, an estimated 270,000 women — and a far smaller number of men — are diagnosed with it. When caught in early stages, it’s usually highly treatable. A promising new form of targeted treatment may expand options available to some women with early-stage breast cancer linked to specific genetic glitches. (Early-stage cancers have not spread to distant organs or tissues in the body.) The BRCA gene: What does it do? You may have heard the term BRCA (BReast CAncer) genes, which refers to BRCA1 and BRCA2genes. Normally, BRCA…

Editor's note: In this blog post, Dr. Sharon Levy interviews her son Isaiah Levy, a college student. We appreciate Isaiah’s insights and comments on social media's impact on teens and young adults. It is hard to remember (or for younger people, hard to imagine) a world without social media, but indeed such a world once existed — and in fact, it is the world humans evolved in. Humans are social animals. Friendly interactions release dopamine in our brains’ reward centers to get us to repeat the behavior. Until recently, that feedback loop suited us very well, with little opportunity to get off track. Social media changed things by providing the…

For years, products containing acetaminophen, such as the pain reliever Tylenol, were largely viewed as safe to take during pregnancy. Hundreds of widely available over-the-counter remedies, including popular cold, cough, and flu products, contain acetaminophen. Not surprisingly, some 65% of women in the US report taking it during pregnancy to relieve a headache or to ease an aching back. But recently, a group of doctors and scientists issued a consensus statement in Nature Reviews Endocrinology urging increased caution around acetaminophen use in pregnancy. They noted growing evidence of its potential to interfere with fetal development, possibly leaving lingering effects on the brain, reproductive and urinary systems, and genital development. And…
