This go-to solution by Jack Black reduces razor bumps and ingrown hairs, and helps prevent new ones from forming. Its powerful combination of 2% salicylic acid and lactic acid exfoliate the top layer of dead skin cells, unearthing the skin-trapped facial hairs that can cause razor bumps and dissolving the pore-clogging facial oils that can cause acne or blackheads. It also contains effective hydrating and soothing ingredients to effectively counteract dryness and irritation.How to use: Apply to clean skin. Moisten a cotton pad and cover the entire affected area (face, neck and back) with a thin layer, 1-3 times daily. Do not rinse. Until your skin acclimates to the treatment, begin with one application daily at night then gradually increase usage to 2-3 times daily. To minimize the chance of irritation or stinging, wait 30 minutes after shaving to use this product.
