Detailed answer

Tricholemmomas are benign tumors that develop from the outer sheath of the hair follicle. They are typically caused by genetic mutations rather than allergies to skincare products. Although allergies can cause skin reactions such as rashes, irritation, or dermatitis, they are not directly associated with the development of tricholemmomas. If you have concerns about tricholemmomas or any other skin condition, it is important to consult with a dermatologist for an accurate diagnosis and appropriate treatment.
