Detailed answer

When someone experiences an allergic reaction to a skincare product, it can trigger physiological changes in the body, including the release of inflammatory substances. These substances can affect the brain and its neurotransmitters, potentially leading to changes in mood. Additionally, the discomfort and irritation caused by the allergy can contribute to feelings of frustration, irritability, and overall mood disturbances. It is important to identify and avoid any skincare products that may be causing an allergic reaction to prevent such mood swings.
