Sometimes our bodies change when we start or stop different medicines, stress or hormones. I stop using birth control pills a few years ago and my skin went crazy. Make sure the astringent doesn’t have alcohol it could be irritating your skin.
Try using a spot treatment product with 2% Salicylic acid or Benzoyl peroxide ,what those products do is exfoliate the dead skin cells off of the blocked pimple. Scrubbing can irritate the skin so harsh scrub shouldn’t be used. You can use a moisturizer for acne prone skin that has a small amount Salicylic acid in it to help keep break out under control.
Hope this helps a little. Sometimes a little ice on the blemish and an Advil will take the swelling down but there aren’t any quick cures. Lisa (RI)
