What to watch with LCT and Haut?

The question about LCT (lactase persistence) and skin is not directly addressed in the provided context. LCT gene variants determine the ability to digest lactose, and non-persistence can lead to intolerance symptoms. A link to skin conditions like acne or eczema is discussed in research but remains inconclusive. The provided sources contain no specific information on LCT and skin. Therefore, the evidence is unclear. Consumers should note that DNA tests like those from MyBody-X offer only genetic hints, not medical diagnoses, and should not be used for self-directed dietary changes. For skin issues, consulting a doctor is recommended.
