Few studies of topical treatment in acne stand up to modern scientific requirements, and several of those which do suggest that some modalities make acne worse rather than better. There is evidence that sulphur, soap, and light treatment prolong the course of illness. This also applies to some components of the vehicles used for acne medicaments. Fortunately, traditional treatment can be abandoned in favour of the superior benzoyl peroxide and retinoic acid.
很少有关于痤疮局部治疗的研究能符合现代科学要求，而且其中一些研究表明，某些治疗方式会使痤疮病情加重而非好转。有证据表明，硫磺、肥皂和光疗会延长病程。这也适用于痤疮药物所用载体的某些成分。幸运的是，可以摒弃传统治疗方法，转而使用更有效的过氧化苯甲酰和维甲酸。
