Similar to Mario Badescu drying lotion which can be purchased and works wonders. I’ve found out that using a q-tip swab with rubbing alcohol on the breakout site following with a dab of hydrocortisone cream works just as well. Using this technique as a spot treatment works well for external use on ingrown hairs as well as pimples. Leave on the skin for at least 6 hours and re apply as needed for up to 24 hours. If condition worsens or doesn’t get better contact a dermatologist for more advice.
