According to ethnobotanist Chris Kilham, tamanu is one of the most effective agents in promoting the formation of new tissue, thereby accelerating wound healing and the growth of healthy skin. This process is known as cicatrization in medical terms. Essentially, it means that tamanu oil is a powerful skin regenerator.
Tamanu oil is hands down, the best oil for healing acne scars and fading old acne scars. It has a thick consistency and is, therefore, better used as a spot treatment for problem areas rather than all over the face. It had a pungent odor reminiscent of bullion cubes, but don’t let that scare you away! It has single-handedly reduced my acne scars more than anything else.
