Bubble and clay cleansing mask. This mask has been created with oily, combination, and blackhead-prone skin in mind, thanks to its black clay, activated charcoal powder, and carbonated water that help to deeply cleanse the skin to remove excess oil and dirt, providing a deep clean that helps control sebum production and improves its appearance by helping to prevent the appearance of pimples, blackheads, blemishes, shine, and other imperfections.
