痤疮的形成和皮脂腺分泌有关,皮脂腺体积的大小和分泌活性因人而异,身体不同区域的皮脂腺分布及活性也不相同,脸部、胸部、背部及颈部的皮脂腺较为密集,也比其他区域发达,因此痤疮大多集中在这些部位。另外,由于身体上的皮肤较厚,毛孔也相对大些,因此有些情况下身体上的痤疮会严重得多。

Body Acne

不管是什么类型的痤疮,对皮肤的刺激都会造成痤疮症状加重,比如对摩擦、挤压、频繁的清洗、潮湿闷热的环境,以及化妆品等,都有可能对皮肤产生刺激。对于胸部或背部等身体上的痤疮,衣物的摩擦、或是出汗等引起的潮湿,也会产生刺激而导致症状加重。

对于颈部痤疮要分两种情况,颈前的皮肤很敏感,如果出现痤疮,要采用和面部一样的护理和治疗方法。颈后的皮肤则比较接近背部,不过这个部位的痤疮往往有明显的痛感,并且可能会长时间存在。

由于对皮肤的刺激会使痤疮加重,因此要尽可能的避免或减少刺激。比如:

  • 尽量穿着柔软的棉质衣物,并保持衣物的干爽,在出汗或潮湿后及时更换。
  • 如果颈部有痤疮,最好选择圆领衣物,以避免衣领摩擦皮肤。当不得不穿有衣领的衣物时,选择柔软的棉质材质。
  • 当皮肤受到刺激后,及时进行护理,比如涂抹乙醇酸制剂或其它产品,以消除刺激带来的不利影响。

不管是身体上的痤疮还是脸部的痤疮,治疗方法是类似的。

轻度痤疮一般采用外用药物进行局部治疗,比如涂抹维甲酸或过氧化苯甲酰类制剂。

中度痤疮患者建议两种或多种药物联合使用,一线用药包括:外用维甲酸+外用过氧化苯甲酰/抗生素,或者是外用过氧化苯甲酰+外用抗生素,如果丘疹、脓包众多,可以在外用药的基础上,在配合口服抗生素。

对于重度痤疮,即非常严重的情况,口服异维A酸是最有效的治疗方法(女性慎用),不过它的副作用广泛存在,用药前须咨询医生。

另外,需要注意的是,对于维甲酸、抗生素、异维A酸等处方药,一定要在医生的指导下使用。

有一种经用户验证的治疗方案是,外用过氧化苯甲酰和乙醇酸联合使用,具体方法为:

使用频率:

晚各一次,间隔10~12小时。

步骤1——清洁皮肤

用温和的清洁产品清洗,以去除皮肤表面的油脂,使药物更好的渗透。

步骤2——涂抹浓度为2.5%的过氧化苯甲酰

双手洗净后,在痤疮部位及周围涂抹浓度为2.5%的过氧化苯甲酰的制剂,用手指轻柔至吸收,用量也要足够。涂药后等候5-15分钟,直至皮肤完全干燥。

提示

如果是敏感肌肤,刚开始可以小量试用,然后逐渐增加用量。另外要注意,过氧化苯甲酰对织物有漂白作用,用药后最好穿白色的贴身衣物。

步骤3——护肤

过氧化苯甲酰被完全吸收后,洗净双手,继续涂抹浓度为10%的乙醇酸制剂,用手轻柔直至吸收。待药物完全被吸收,并且皮肤干燥后再穿衣。

提示

当痤疮已经消除,进行后续维持治疗时,可以尝试早上不再涂抹过氧化苯甲酰,而只使用乙醇酸,晚间还是继续同时使用过氧化苯甲酰和乙醇酸,这种方法对于不严重的身体痤疮较为有效。
