I don’t really have problem skin, but once in a while one appears. In the middle of the face. Rescue 911 is the Drying Lotion from Mario Badescu. It is an effective acne spot treatment, that shrinks whiteheads overnight. It is safe for sensitive skin and will not irritate. Before bed – cleanse, tone and moisturize – then dip a cotton swab into the pink sediment at the bottom of the bottle. Do not shake the bottle. Apply a dab of the lotion directly to your problem and let it dry overnight. Et voilà. I have heard that it will also take the itch out of mosquites bites fast – I hope and will let you know when we get to mosquito season. You can shop Mario Badescu right here.
