Your genetic code affects every aspect of your body. It determines your potential height and intelligence. It determines your eye color and body shape. It determines your skin color. However, your genetic code affects other aspects of your skin you may not have realized. For example, the tendency toward dry or oily skin is genetic, as is the innate size of your pores. Your genetics can affect your skin indirectly, whether it is your ability to tan quickly or greater odds of getting sunburned.
We used to use trial and error to determine the right skincare products for us. A trained professional could give expert advice, but there were still uncertainties. That meant less trial and error (and expense) than if you were buying things on your own, but it wasn’t certain to work much less be ideal. The best skincare products are those that are truly a match with your skin type and your needs.
This is where genetic testing can come in.
How does genetic testing relate to skincare?
We’ve already explained how genetics impact your skin. There are now companies offering genetic testing to determine your personal risk factors and sensitivities. For example, a home dna skin care kit will look determined which genetic markers you have. The healthcare provider will use this information to determine what your skin is like, and they can recommend skin care products based on that information.
What are the limits of skin DNA tests?
A skin DNA test won’t diagnose every condition affecting your skin. For example, it won’t identify sunburn or an allergic reaction to your wool sheets. It may flag an increased risk of eczema or psoriasis, but this doesn’t mean you have them. Skin genetic tests may or may not diagnose skin infections, whether you have ringworm, scabies, or a staph infection. If you’re dealing with itchy, red, or swollen areas, wait to get a skin DNA test and see a doctor about the potential infection. Then you can get the condition treated, and it won’t skew the genetic test results.
Genetic testing can identify a tendency toward rosacea or hives, but it won’t register a human papillomavirus infection, whether it is cold sores or worse. If the skin irritation is seemingly spreading, consult with a dermatologist. The same is true if you have a wart or lesion that is changing color, increasing in size, or starting to bleed. This may be skin cancer. While that could be diagnosed via a biopsy, it requires medical attention.
What else might I learn from a genetic test?
There are companies that are willing to analyze your genetic code for information regarding your health. They may identify a tendency to accumulate iron or failure to absorb enough calcium. These companies may provide advice on nutrition or use the information to sell you vitamins. A few use it as a lead-in to personalized fitness and nutrition counseling. That healthy living advice is truly personalized once you’ve given the counselor information about your current lifestyle and health status.
