I have 3 large black pimples on my arm and thigh. The dermatologist said that they're ingrown hairs and that it would leave scars if they tried to removed them. I started using this salve about a month ago and the ones on my arm are almost flat and the color has lightened a bit to brown. The one on my thigh will need more time, probably because the salve is rubbed off by my clothing. For some reason that doesn't seem to happen as much with those on my arm. I use this twice a day, in the morning and again in the evening. I dab a little on the tip of my finger and then rub it in the bump for a few seconds.I highly recommend this product!
