The Best Natural Ingredients That Fight Acne, as Proven by Science

The immune systems of tea trees are particularly effective at destroying bacteria. The oil extracted from the tree possesses the same powerful anti-bacterial properties. And when used in skincare, its bacteria-fighting abilities are actually comparable to benzoyl peroxide, making it an excellent, natural alternative to chemical ingredients.

Sulfur is one of the oldest skin remedies still in existence, with treatments dating back to ancient times. And for good reason, the mineral is a natural oil absorber that also eases inflammation and helps to exfoliate dead skin cells. Yes, it smells (like rotten eggs), but its ability to draw excess oil and sebum out of pores make the odor more tolerable.

Willow bark extract is actually a natural form of salicylic acid, and it happens to be another time-tested cure. People have been tapping into the white willow tree for centuries—long before the synthetic version of proven breakout solution was created. Willow bark extract works to slough off dead cells to keep your pores clear of debris (even better than salicylic acid, some experts say). Add it to your routine to ease existing breakouts and avoid future ones.

Like many of the ingredients on this list, green tea provides anti-inflammatory and anti-bacterial benefits. It directly helps with acne because the compounds that fight off infection in the green tea plant function similarly in skincare—going straight to the acne lesion and killing the bacteria. But green tea also packs the antioxidant punch, making it an incredible healer and a good choice for improving the overall health of your skin.

Clay is primarily known for its oil-absorbing action, but it’s also a rather calming and soothing mineral (thanks to those trusty anti-inflammatory properties). Kaolin (also known as white China clay) is one of the gentlest clays. It clears your complexion of pore-clogging toxins and impurities, and removes excess oil and dirt, without drying out your skin.

Sage extract is another antioxidant-rich ingredient in the bunch. It’s known to protect skin cells from damage, prevent dryness, and promote healthy skin. All of which translates into good news for stressed-out complexions. The natural extract reduces redness and irritation while also purifying the skin. Use it to soothe inflamed skin and prevent acne-causing inflammation from popping up again.
