Various methods of bathing may affect skin properties differently.
To compare the effects of immersion and showering on skin hydration and transepidermal water loss (TEWL).
This experimental study included healthy volunteers whose forearms were immersed and showered for 3 minutes. Skin hydration and TEWL were assessed serially before and after immersion and showering of volunteer forearms.
Seventy-eight healthy volunteers (49 females, 29 males) were enrolled with an age range of 12-55 years (mean 31.41 ± 10.33). Both methods significantly increased skin hydration and TEWL (P < .001). The capacitance value significantly increased immediately after bathing, and then rapidly decreased within 3 minutes. It returned to baseline by 10 minutes after bathing. There was no statistically significant difference of capacitance between the two methods at any measurement (P > .05). TEWL at every measurement after bathing was significantly increased compared to baseline for both bathing methods (P < .001). The highest TEWL was observed immediately after bathing, but then significantly decreased compared to the previous measurement (P < .001).
Immersion and showering similarly demonstrated significant increase in skin hydration and TEWL. The increment of capacitance after bathing returned to baseline level within 10 minutes.
不同的沐浴方式可能会对皮肤性质产生不同的影响。
比较浸泡和淋浴对皮肤水合作用和经皮水分流失（TEWL）的影响。
本实验研究纳入了健康志愿者，他们的前臂分别进行了 3 分钟的浸泡和淋浴。在志愿者前臂浸泡和淋浴前后，连续评估皮肤水合作用和 TEWL。
共纳入 78 名健康志愿者（女性 49 名，男性 29 名），年龄在 12-55 岁之间（平均 31.41±10.33）。两种方法均显著增加了皮肤水合作用和 TEWL（P<.001）。电容值在沐浴后立即显著增加，然后在 3 分钟内迅速下降。沐浴后 10 分钟恢复基线。两种方法在任何测量时间的电容值均无统计学差异（P>.05）。两种沐浴方法后，TEWL 在每次测量时均显著高于基线（P<.001）。最高 TEWL 出现在沐浴后立即，但与前一次测量相比显著降低（P<.001）。
浸泡和淋浴均显著增加皮肤水合作用和 TEWL。沐浴后 10 分钟内，电容值恢复至基线水平。
