Can BDNF help with Haut?

The provided context does not include specific information about BDNF and skin. BDNF (Brain-Derived Neurotrophic Factor) is primarily known for its role in neuronal growth and brain plasticity. Some research suggests it may also be involved in skin conditions such as psoriasis or wound healing, but the evidence is limited and preliminary. DNA tests for BDNF variants (e.g., Val66Met) exist, but their relevance to skin health is not established. Without clinical validation, decisions about skincare or supplementation should not be based solely on a BDNF genetic test. Consult a dermatologist for evidence-based advice.
