Is Insulin useful for Haut?

The question of whether insulin is useful for the skin requires a nuanced answer. In clinical practice, insulin is primarily used to lower blood glucose in diabetes, not for skin care. However, basic research suggests insulin can promote wound healing and stimulate collagen synthesis, which is why it is sometimes investigated in specialized wound dressings or dermatological formulations. These applications remain experimental and are not established as standard therapy. For healthy skin, insulin offers no proven benefit; uncontrolled use (e.g., as a cream) carries risks such as hypoglycemia or skin irritation. The evidence is purely mechanistic, lacking robust human clinical trials. In summary: insulin is not a skin care product and should only be considered under medical supervision for specific indications like chronic wounds.
