Thankfully, we tapped dermatologists to get the scoop on under-the-skin pimples so we can tackle them once and for all. And the best part is, this type of breakout can be easily treated at home, even using ingredients from your pantry. Keep reading to learn what under-the-skin pimples are, what causes them, and how to treat them asap. But one of the best options to pair with tea tree is pumpkin seed oil. “Pumpkin seed oil is rich in unsaturated fatty acids that can help reduce inflammation, and it also has anti-androgenic effects,” says board-certified dermatologist Keira Barr, M.D. “You can dilute 1 to 5% tea tree oil in pumpkin seed oil to support acne treatment.” For a gentle, at-home trick, we love alpha-hydroxy acids (or AHAs). AHAs are water binding, making them the better option for those with sensitive, dull, or dry skin. “They can be simultaneously exfoliating and hydrating, making them very beneficial to many skin types,” says board-certified dermatologist Mona Gohara, M.D. Lactic acid is a very popular AHA and is found naturally in dairy products like yogurt and buttermilk. How so? Well, retinol interacts with the skin’s receptors, beneficially altering the genes involved with inflammation and cell growth. This reduces the formation of microcomedones3, or skin pores clogged with sebum, bacteria, and dead skin cells. (Microcomedones are the precursors to all pimples, so stopping them can make a huge difference.) Retinol also exfoliates within the pores, “where slowed dead cell shedding leads to enlarged pore appearance and breakouts,” says board-certified dermatologist Loretta Ciraldo, M.D., FAAD. After a pimple has come and gone, retinol can help decrease post-breakout scarring as well. In addition to exfoliating dead skin cells, retinoid blocks the activity of enzymes4 behind melanin synthesis, resulting in a more even skin tone. If you’re new to retinol, consult with your dermatologist first to avoid any irritation, redness, or drying.
