Good regimen: The skin care regimen you have been prescribed is a fairly standard combination of acne medications that typically help most people. Excessive dryness is not uncommon at the start of therapy, but can be minimized by a non-comedogenic moisturizer such as Cetaphil. Stick with it, as transient flare ups after 30 days are common but generally not recurrent.
