青春豆患者“8不要”  
1.不要常常洗脸；  
一天早中晚各洗一次脸即可。洗脸太多，反而刺激皮脂腺的分泌功能，因为一旦皮肤表面的油脂被洗净，皮脂腺就会“加班”工作，来发挥其天然保护功能。如此一来皮脂腺就会变得越来越旺盛，越来越活泼，从而分泌更多的油脂。  
2.别乱挤青春痘；  
每一个青春痘的生命周期，都仅有短段的3-4天，到时候它自然会消失或化脓而出。如果用手或工具去挤，或因挤压过力造成皮下淤血，留下永不消失的痕迹。  
此外，因抠挤而造成的伤口，经一再的刺激使皮肤增生，结果易形成隆起的疤痕。  
3.不要吸烟；  
香烟中的尼古丁会收缩微血管管壁，使血液和淋巴中的毒素堆积，因而使皮肤的愈合能力减弱，易于形成痤疮伤口的感染。  
4.不要使用磨砂膏和收敛水；  
使用磨砂膏和收敛水会过度刺激表皮，恶化已经在发炎的皮肤状况，同时也会激化皮脂腺的分泌功能，使情况更糟。  
此外，收敛水也使毛孔收缩，让原本已经堵塞的毛孔洞口更小。  
5.避免高碘食物；  
食物对青春痘没有绝对的影响力，即使最严格的饮食习惯，也无法预防和治疗痘痘。但反过来有些食物却加剧青春痘的恶化。专家告诉我们，应避免高碘食物，因过量的碘含量会使已经存在的痘痘大量长出。  
6.避免过多精制糖类；  
学者研究发现，过多的精制糖类摄取，会使人体免疫力下降，容易造成伤口细菌感染问题。所以尽量避免摄取过多精制糖类。  
7.少吃辛辣、高热量、油腻食品；  
虽然这些食物并不能直接造成青春痘的形成，但是却会令痘痘恶化，因为这些食物会增加心脏的负荷能力，并使毛囊内的EGF因子大量流失，间接诱发了青春痘的形成。  
8.避免不正确的“进补”；  
过多摄入某些富含性激素类的营养品会破坏内分泌平衡，使雄性激素分泌亢进，从而直接诱发青春痘。
