Do you like your coffee strong, weak, or in your sunscreen? If your answer is the latter, you may be better protected against the sun’s rays. A study published in the Proceedings of the National Academy of Sciences shows that caffeine could beneficially alter a gene to prevent cancerous cells from forming.
The study used mice to show that the caffeine suppresses the ATR gene, causing DNA-damaged cells to die. The mice whose ATR genes were inhibited developed almost two-thirds fewer tumors than the control.
The study may have substantial ramifications for the manufacturing of sunscreen. It is likely that the addition of caffeine to sunscreen could reduce the likelihood of tumor development. The study did not take drinking caffeine into consideration.
Until there’s more data on the effects of topical caffeine, it’s best to take the study with a grain of salt. Of course, the best way to prevent against skin cancer is to apply sunscreen when you go outside and to re-apply often. Also, if you notice moles that are abnormal, be sure to schedule a visit with your dermatologist.
Your skin is the largest organ in your body, and it’s extremely absorptive. Ingredients in creams, lotions, and sunscreens could end up in your bloodstream, which is why it’s very important to choose high-quality products that are approved by your dermatologist.
Recently, several Texans learned this lesson the hard way. Within a short period of time, 18 individuals who live in South Texas tested positive for increased levels of mercury in their blood after using a facial cream they had bought in Mexico, Crema Aguamary. When the Texas Department of State Health Services tested the cream, results showed mercury levels at thousands of times more than is legal for products sold in the United States.
Crema Aguamary is not sold in Texas, but the individuals who had mercury poison had purchased the cream in Mexico and brought it across the border. Health officials are warning residents, especially those close to the border, to refrain from buying health supplies in Mexico.
Consumption of mercury, including absorption through the skin, can result in digestive tract, kidneys, and nervous system dysfunction or failure. We suggest purchasing high quality products from your trusted dermatologist.
Many dermatologists across the nation are seeing a boost in their male clientele who seek laser hair removal as technology has advanced. Initial laser hair removal could only comfortably manage small areas, such as the underarms or bikini line. However, lasers with larger target areas are making it feasible to remove hair from areas commonly of concern to men, such as the chest and back.
Pseudofolliculitis barbae, characterized by irritation of the skin and in-grown hairs, is a common condition in men that can be well treated by laser hair removal. Improvement is often noted after just one treatment, with several treatments usually yielding long lasting results.
Laser hair removal is just as effective for men as it is for women, and many men are turning to their dermatologist for hair removal rather than spending money on shaving, waxing, trimming hair. If you’re interested in laser hair removal, contact Dr. Zimmet’s office.
