Detailed answer

Blackheads, also known as open comedones, are caused by a build-up of excess oil and dead skin cells within the pores. They are not directly related to caffeine consumption. However, caffeine can potentially worsen certain skin conditions such as acne or rosacea due to its stimulant properties. This is because caffeine may increase sebum production and inflammation in some individuals, leading to the formation of pimples and redness. Proper skincare, including regular cleansing and exfoliation, as well as a balanced diet and lifestyle, are important for managing blackheads and other skin issues.
