How are Fitness Vitality DNA and Haut related?

The relationship between the Fitness Vitality DNA test and skin (Haut) is not clearly established from the available context. The test is not explicitly mentioned in the provided knowledge snippets. Other MyBody-X tests like the Slim DNA test (weight loss) and Fitness LifestyleCheck (blood markers such as vitamin D, B12, creatine kinase) are referenced, but no direct link to skin health is given. Vitamin D and certain antioxidant genes (e.g., rs1800566) can influence skin, but the Fitness Vitality DNA test likely does not specifically analyze these. The evidence level is 'unclear' or 'marketing'. Without detailed product information, any claim about skin benefits remains speculative. For skin concerns, consult a dermatologist or a healthcare professional.
