Your genetic makeup influences almost everything about your body. It dictates your potential height, intelligence, eye color, body shape, and even skin color. But did you know that your genes also play a role in other aspects of your skin that you might not be aware of? For instance, whether your skin tends to be dry or oily, or the natural size of your pores, is all down to genetics. Your ability to tan easily or your likelihood of getting sunburned are also genetically influenced.
In the past, finding the right skincare products was often a game of trial and error. While professionals could offer expert advice, there was always some level of uncertainty involved. This usually meant spending a lot of time and money on products that might not be suitable for your skin. Ideally, the best skincare products should perfectly match your skin type and its specific needs.
This is where genetic testing comes into play.
How does genetic testing relate to skincare?
As mentioned earlier, genetics have a significant impact on your skin. Nowadays, some companies offer genetic testing services to identify your personal skin risk factors and sensitivities. For example, a home DNA skincare kit can reveal which genetic markers you have. Healthcare providers can then use this information to determine the characteristics of your skin and recommend suitable skincare products.
What are the limits of skin DNA tests?
It’s important to note that a skin DNA test won’t diagnose every issue with your skin. For instance, it can’t detect a sunburn or an allergic reaction to your wool sheets. While it may indicate a higher risk for conditions like eczema or psoriasis, it doesn’t confirm that you have them. Skin DNA tests also won’t diagnose skin infections like ringworm, scabies, or a staph infection. If you have red, itchy, or swollen skin, it’s best to see a doctor for potential infections before considering a genetic test, as you’ll need to treat the condition first.
Genetic tests can reveal a predisposition to issues like rosacea or hives, but they won’t detect viral infections like HPV, which can cause cold sores or other problems. If you notice a skin irritation spreading, or a wart or lesion changing color, growing, or bleeding, it’s crucial to consult a dermatologist. These could be signs of skin cancer, which requires medical attention and sometimes a biopsy.
What else might I learn from a genetic test?
Some companies offer to analyze your genetic information to provide insights into your overall health. They might identify whether you’re prone to accumulating too much iron or not absorbing enough calcium. These findings can lead to advice on nutrition or suggestions for vitamins. Some companies use this information to offer personalized fitness and nutrition counseling. This advice becomes truly tailored when you provide details about your current lifestyle and health status.
