Is NutriCare | INFINITY DNA-Test useful for Haut?

The NutriCare | INFINITY DNA-Test is a commercial genetic test claiming to offer personalized recommendations for skin health. However, the scientific evidence supporting its utility is weak. While certain gene variants (e.g., in NFE2L2, involved in antioxidant defense) have been linked to skin aging or sensitivity, the effects are generally small and overshadowed by lifestyle factors such as UV exposure, diet, and smoking. Most skin conditions are polygenic and strongly influenced by environment. Therefore, this test cannot provide clinically actionable advice for preventing or treating skin issues. It may offer general insights, but these are unlikely to surpass common dermatological knowledge. Independent validation studies for the specific claims of this product are lacking. Consumers should be cautious: the evidence does not support using such tests for personalized skincare regimens. For skin health, proven strategies like sun protection, a balanced diet, and consulting a dermatologist remain far more effective.
