Clean and dry the skin, center a patch over the blemish and press for 3 to 5 seconds. Leave it on for about 8 hours or overnight and remove it once the patch turns white.

Do they work on cystic acne?

They work best on whiteheads and surface pimples where hydrocolloid can pull out fluid. Deep, painful cysts under the skin usually need a dermatologist's treatment.

Are they safe for sensitive skin?

Salicylic acid and tea tree oil can sting or dry out sensitive skin. Test one patch on a small area first and avoid broken or irritated skin.

Can I wear them during the day?

Yes, but the star, moon and droplet shapes are noticeable up close. They are better suited to overnight wear or days at home.

Do they help with redness after a pimple heals?

The salicylic acid and tea tree oil are meant to calm irritation and fade red marks, but results vary and take repeated use.
