Cala Blemish Patches are hydrocolloid acne patches infused with salicylic acid to help treat and heal blemishes. Each pack contains 72 transparent dots that adhere to the skin to absorb excess fluid while protecting the affected area from external irritants. These patches are designed to be worn during the day or night and should be applied to clean, dry skin. The patches work by creating a moist environment that helps draw out impurities while the salicylic acid works to unclog pores. Remove patch once it turns white or after 8-12 hours of wear. The package contains 72 patches that come in assorted sizes to accommodate different blemish sizes.
