Warren symposium follows legacy of geneticist giant

If we want to understand how the brain creates memories, and how genetic disorders distort the brain’s machinery, then the fragile X gene is an ideal place to start. That’s why the Stephen T. Warren Memorial Symposium, taking place November 28-29 at Emory, will be a significant event for those interested in neuroscience and genetics. Stephen T. Warren, 1953-2021 Warren, the founding chair of Emory’s Department of Human Genetics, led an international team that discovered Read more

Tracing the start of COVID-19 in GA

At a time when COVID-19 appears to be receding in much of Georgia, it’s worth revisiting the start of the pandemic in early 2020. Emory virologist Anne Piantadosi and colleagues have a paper in Viral Evolution on the earliest SARS-CoV-2 genetic sequences detected in Georgia. Analyzing relationships between those virus sequences and samples from other states and countries can give us an idea about where the first COVID-19 infections in Georgia came from. We can draw Read more

Sunscreen: Looking Beyond the Numbers

Recently, the Food and Drug Administration created new regulations to establish standards for sunscreen manufacturers to follow before they label their products.

Under the new regulations, which will go into effect in 2012, sunscreen products that protect against all types of sun-induced skin damage will be labeled “broad spectrum” and “SPF 15” or higher on the container. Only products that have been tested to ensure they protect against both UVA (ultraviolet radiation A) and UVB (ultraviolet radiation B) radiation will be allowed to use this labeling. Broad-spectrum sunscreens of SPF 15 and higher can also be labeled as protective against skin cancer and premature aging. The maximum SPF value is set at 50-plus because the FDA says anything higher doesn’t provide a significant amount of additional protection.

Manufacturers will have to include warning labels on products that are not broad spectrum. Products that claim to be water resistant must indicate how long the consumer should expect to be protected in the water, and using such language as “waterproof” or “sweat proof” will not be allowed.

“Skin cancer is the most common form of cancer in the United States, and the number of people affected keeps rising. Simply getting into the habit of using a sunscreen every day – with the appropriate levels of protection – can make a significant difference in preventing many skin cancers, as well as premature aging,” says Washington. If you’re looking into anti-aging treatments though, you can go to experts such as Dundee Dermatology or Mint Nutrition.

These new regulations will help consumers understand the difference in degrees of sun protection, and choose carefully. To learn more about dermatology, you can choose to attend conferences such as this Aesthetics Conference.

Washington also suggests staying out of direct sunlight between 10 am and 2 pm, seeking shade when you are outdoors, remembering to reapply sunscreen every two hours and wearing protective clothing.

Facing the Facts on Skin Care

Dr. Anita Sethna

Dr. Anita Sethna, director of the Emory Facial Center.

The desire to look good and feel great about ourselves doesn’t disappear when we hit 50, 60 or even age 70  Caring for your skin is the most important way to impact the way you age.

Looking good does not have to involve drastic procedures, says Dr. Anita Sethna, director of the Emory Facial Center.  There are small, simple and affordable ways to care for your calling card to the world:  your face.

Dr. Sethna offers these tips:

  • Protect yourself against sun damage. Wearing makeup or moisturizer with sunscreen daily is incredibly important, advises Sethna.  The more careful you are about protecting yourself against even daily skin exposure, the less damage you will be causing your skin as you age; decreasing your chances of getting skin cancer and preserving the texture and plumpness of your skin. This applies to all skin types, genders and degrees of pigmentation. She recommends products that give at least 30 UVA/UVB protection.
  • Quit smoking. Smoking is not only horrible for your health, but is also horrible for your skin, she warns. Nicotine causes a decrease in blood supply to the skin and reduces its ability to heal, eventually giving it a leathery look.
  • Some products can help. Many of us are aware of the benefits of using moisturizers to maintain healthy-looking skin, especially as we age. However, what you might not know is that face oils can have active ingredients that can help to improve the appearance of your skin. While over-the-counter moisturizers can work just fine, using products containing retinol and antioxidants like Vitamin C can help to stimulate collagen production, which is essential for maintaining the skin’s elasticity and fullness. Additionally, incorporating pine tar bar soap into your skincare routine can provide natural antibacterial properties and soothing relief for various skin conditions.
  • For even better results, prescription strength products such as Retin-A and skin lighteners like hydroquinone can be recommended by a skincare specialist like Sethna. For those who want to take wrinkle prevention a step further, Botox injections can be carefully used in certain areas of the face to reduce repetitive motion of the skin and soften lines around the eyes, between the eyebrows, and on the forehead. In some cases, these injections can even prevent the formation of new lines on the face.

Sethna also wants us to remember that perfection is fine when you’re talking about a painting or a new dress, but our face is a different story.

Perfection should not be a goal when you are talking about your appearance. Your expression, quirks and small imperfections make you – you, and also make you beautiful.  You should not be embarrassed or ashamed at wanting to preserve that beauty.
