Talcum powder may cause acne, but the situation is different due to individual differences. Talc is an industrial product that can be used in the production of plastics, paints, cosmetics, etc. If you use cosmetics containing talc ingredients, it is easy to clog pores, causing an accumulation of lipids secreted by the body, triggering an inflammatory reaction in the skin and leading to the formation of acne. “Acne” is the common name for acne, the factors that cause acne can be divided into endogenous and exogenous, exogenous factors include cosmetics, drugs, smoking and so on. Talcum powder is one of the exogenous causes of acne because it contains a large amount of silica, which can play the role of sunscreen and is widely used as a filler in the cosmetic industry. Patients with acne are advised to go to the hospital and follow the doctor’s instructions for standardized treatment.
