I had the bright idea of trying a new skin routine which included using "sea buckthorn oil" on my oily, acne prone skin. Within a couple days my skin freaked out whiteheads, little red bumps, you name it. I saw the calma mask and decided to give it a try. I used it for 20 minutes the first day, and the second I used as a spot treatment at night. The next morning My skin was almost back to normal. I know after one more use my skin will be completely clear again.
