[The practice guideline 'Acne' (second revision) from the Dutch College of General Practitioners; a response from the perspective of general practice].

The strength of the second revision of the practice guideline 'Acne' from the Dutch College of General Practitioners (NHG) lies mainly in bringing its therapy up to date. The guideline also points out psychosocial problems that can arise with acne, but discounts stress and diet as the possible cause. Schedules showing a medical plan of action and information on medications complete this clear and practical guideline.
