Although you still need to wash your face twice a day, try using a cleanser that has salicylic acid in it just once a day to start. Britt Kimmins notes that salicylic acid is especially good for those with dry skin.
You may consider using it at night only and then using your regular cleanser in the morning. As your skin gets used to the product, you may choose to use it both morning and night.
Many people are sensitive to salicylic acid. You may not be able to use it more than once every few days. If you continue to react to it, discontinue use.
In the past, you may have heard that exfoliating produces a negative effect on acne. This can be true for inflammatory acne, as the process can cause further redness and irritation.
