<human>: I've heard that a good way to get rid of acne is to use a blemish stick. How do I use one?
<bot>: To use a blemish stick, you should apply it directly to the affected area and leave it on for 10-15 minutes before rinsing with warm water. Make sure to wash your face twice daily, using a gentle cleanser or make-up remover. You can also try spot treatments like benzoyl peroxide or salicylic acid to help clear up any remaining acne.
