Microdermabrasion is a popular method for facial rejuvenation and is performed worldwide. Despite its extensive usage, there are few publications on skin barrier change after microdermabrasion and none concerning diamond microdermabrasion. Our object was to see changes in transepidermal water loss (TEWL), hydration and erythema of the face following diamond microdermabrasion. Twenty-eight patients were included in this spilt face study. TEWL, stratum corneum hydration and the degree of erythema were measured from the right and left sides of the face (forehead and cheek) at baseline. One side of the face was treated with diamond microdermabrasion and the other side was left untreated. Measurements were taken right after the procedure and repeated at set time intervals. Diamond microdermabrasion was associated with a statistically significant increase in TEWL immediately after the procedure and at 24 h. However, on day 2, levels of TEWL were back to baseline. An increase in hydration and erythema was observed right after microdermabrasion, but both returned to baseline on day 1. The results show that skin barrier function of the forehead and cheek recovers within 2 days of diamond microdermabrasion. Diamond microdermabrasion performed on a weekly basis, as presently done, is expected to allow sufficient time for the damaged skin to recover its barrier function in most parts of the face.
微晶磨削是一种流行的面部年轻化方法，在全球范围内都有应用。尽管它的应用非常广泛，但关于微晶磨削后皮肤屏障变化的文献很少，更没有关于钻石微晶磨削的文献。我们的目的是观察钻石微晶磨削后面部经皮水分丢失（TEWL）、皮肤水合度和红斑的变化。这项分割面部研究纳入了 28 名患者。在基线时，从面部（额部和颊部）的右侧和左侧测量 TEWL、角质层水合度和红斑程度。一侧面部接受钻石微晶磨削治疗，另一侧不治疗。治疗后立即和设定的时间间隔进行测量。钻石微晶磨削后 TEWL 立即显著增加，并在 24 小时后仍保持较高水平。然而，在第 2 天，TEWL 水平恢复到基线。治疗后即刻和第 1 天观察到水合度和红斑增加，但均恢复到基线水平。结果表明，钻石微晶磨削后额部和颊部的皮肤屏障功能在 2 天内恢复。目前每周进行一次钻石微晶磨削，预计在面部的大多数部位，足够的时间可以让受损的皮肤恢复其屏障功能。
