It cannot be denied that the rise of the DNA kit fueled by ancestry is not slowing down in the short term, especially since those 23andMe announcements. DNA tests focusing on beauty are also gaining popularity in recent times, especially as new companies (and even spas) present new kits and experiences that offer consumers personalized hair and skin care products based on genetics.
New hair care companies like Strands Hair Care, for example, claim to eliminate guesswork by finding the right shampoo and conditioner by creating an exclusive Strand kit. This kit allows customers to send a hair sample (from a brush or haircut) to receive personalized hair care products based on the test results. Similarly, ORIG3N, a wellness genetic testing company, offers personalized services. beauty DNA tests To explain how it looks, feels and reacts your skin and hair to various conditions.
But do they work? We speak with experts from both sides.
This is what advocates say about beauty DNA tests.
Elina Fedotova, cosmetic chemistry and founder of Elina Organics Skin Care and Spasrecently released a 15-minute genomic formula consultation at your Chicago-based spa. The consultation (which can cost between $ 70 and $ 350), according to Fedotova, works by analyzing a saliva sample (obtained through a cotton swab) to assess what is causing inflammation and how the skin will age. Fedotova uses the test results to create customized serums and cream products. Genetics, Fedotova said, says a lot about the function of skin and hair, and can play an important role in the search for the perfect shampoo or moisturizer.
"All the cells in our body contain nuclear DNA (with the exception of red blood cells and several layers of superficial dead cells)," Fedtova wrote to HuffPost. The DNA "gives specific instructions to each cell on what to do, how to grow and how to reproduce," he added. The cells in the outer layer of the epidermis form what is called the cornified layer, the protective layer of dead cells that make up the skin, hair and nails.
Fedtova argued that DNA tests can be useful to address the root of skin care problems, such as acne and discoloration, as these tests analyze specific genes responsible for skin function.
"Sometimes we cannot solve difficult skin problems for some clients who use existing skin care products, so they may require a customized formulation based on their DNA test," Fedotova said. "For example, for stubborn acne or discoloration, we have to collect DNA from a client and observe specific genes responsible for skin function."
Personalized skin care resulting from DNA tests seems to have benefits. A 2018 study published in Clinical, cosmetic and research dermatology He suggested that an individual approach to the skin (by looking at factors such as biomarkers, hormones and the stress response) may be an effective and affordable way to treat skin conditions. Board-certified plastic surgeon Manish Shah He said that another advantage associated with these tests is the information they provide to the consumer.
"If you are looking for an in-depth guide on what is good for your skin and how to prevent certain conditions from happening, then DNA test kits are the way to go," Shah said. "These kits provide you with supporting information about any condition (or type of skin you have), as well as the products and ingredients that you must put on your skin to address these problems."
This is what detractors warn.
Dermatologist certified by Dan Belkin Council Such personalized skin care or medicine developed with DNA markers is definitely exciting. But genetic tests may still not be able to detect rare skin disorders as a trained professional would.
"What many of these kits claim to cause is the propensity for common conditions, such as xerosis (dry skin), rosacea (blush and sensitive skin), tanning ability, skin aging, sunspots, sunburn, cellulite and eczema, "Belkin said. "However, there are rare dermatological conditions for which a board-certified dermatologist may need to verify certain genetic markers."
And then there is concern about the accuracy of the test. That according board certified dermatologist Peterson Pierre, It's a bet. DNA tests focusing on beauty, according to Pierre, contain a false positive rate of up to 40%. He suggested building a solid skin care regimen with the help of a trained professional.
"When it comes to building an effective skin care routine that delivers results, it is better to leave that job to the experts, that is, to your board-certified dermatologist, who has access to the best science and the best products "Pierre explained.
Beauty-focused DNA kits also face problems of bias and objectivity, according to Belkin, because many tests tend to recommend products sold by the same company.
"Many of the beauty-focused DNA tests are associated with the brand's product line to sell its products," Belkin said. "As in any place where there is a conflict of interest, their recommendations should be considered with skepticism."
In the end, beauty-focused DNA kits definitely take the personalization experience to a whole new level, especially with personally formulated products based on the test results. Testing can also help consumers provide detailed information about the health of hair and skin, which ultimately allows people to make smarter buying decisions.
However, Pierre said that genetic testing for beauty purposes is still in diapers, as is the development of products based on the results of these tests.
"These kits will definitely give you a better understanding of the science behind your skin, but we are far from developing a skin care routine based on the results of these tests," said Pierre. "There are simply too many variables left out, including diet, sun exposure and skin sensitivity."
