2. A Five-Pack Of Tea Tree Sheet Masks To Clarify & Exfoliate Your Skin

Mediheal Tea Tree Essential Blemish Control Mask (5-Pack)

Mediheal is Korea's number-one sheet mask brand — yet somehow, they've managed to remain relatively under the radar in the U.S. Their tea tree sheet masks are a great choice for anyone with acne-prone, oily, or generally congested skin. Willowbark, rosemary, and tea tree, which have purifying and exfoliating properties, all make appearances in the formula, while chamomile and pennywort help calm redness and irritation.

"This is probably my favorite sheet mask for calming my skin when I have inflamed acne lesions," commented one reviewer. "When I have active breakouts, I like to leave this mask on until it dries completely, which seems to help reduce the size and redness of acne much more than simply leaving the mask on for 20 minutes."

Another fan, with self-described dry, sensitive, acne-prone skin simply wrote, "Exceptional quality and results."
