If you often stay up late, you're likely to have oily hair, folliculitis, seborrheic dermatitis, and dandruff. Consequently, you may also experience itchy ears. If, like me, you've visited the hospital for examination with no results, and the doctor says everything's fine but the itching persists, then go buy a bottle of iodine tincture. The design of iodine swabs is particularly ingenious for this purpose. 如果你是熬夜选手，大概率你会油头，会容易有毛囊炎、脂溢性皮炎，头皮屑，那么你大概率也会耳朵痒，如果跟我一样去医院检查无果，医生说没事还是痒，那么去买瓶碘伏吧，碘伏棉签这个设计就很妙。 又是免费带货的一天。😆
