Detailed answer

Basal cell carcinoma is a type of skin cancer that develops in basal cells, which are found in the deepest layer of the epidermis. While allergies to skincare products can cause skin irritation, redness, and itching, there is no evidence to suggest that allergies directly cause basal cell carcinoma. Basal cell carcinoma is primarily linked to excessive sun exposure, especially on areas of the skin that are regularly exposed to the sun, such as the face and scalp. It is important to protect the skin from the harmful effects of the sun by using sunscreen, wearing protective clothing, and avoiding prolonged sun exposure. Regular skin checks and early detection are also key in identifying and treating basal cell carcinoma.
