Detailed answer

Allergies to skincare products generally result in skin reactions such as redness, itching, and inflammation. Hair growth on unusual areas is not a typical symptom of an allergic reaction. However, certain skincare products may contain ingredients that can stimulate hair growth, but these ingredients are not typically associated with allergic reactions. If you are experiencing hair growth on unusual areas, it is important to consult with a medical professional to determine the underlying cause as there could be other factors involved, such as hormonal imbalances or underlying medical conditions.
