Thursday Plantation Tea Tree Medicated Gel For Acne - 25g tube is a clear gel for invisible application. It contains 20% Tea Tree Oil, making it one of the most powerful natural acne medications available. The gel helps to control acne bacteria and unblocks the skin's sebaceous ducts, which, if left unattended, form whiteheads, blackheads, pimples and acne lesions. A small amount of camphor in the formulation helps to cool the skin and can reduce itchiness.
