Treatment products include gels, lotions, and creams for the whole face as well as spot products for single acne lesions. Gels and solutions are generally stronger, but may be a little drying. Creams are recommended for winter months as well as dehydrated skin. Treatment components may include Retinol, fruit acids, sulfur, Azelaic acid, and other ingredients to penetrate pores, kill bacteria, and get rid of old acne lesions while preventing the new ones. Treatments should be used in the morning after cleansing and in the evening to restore, hydrate, and replenish your skin.
