Optothermal infrared spectrometry (OTIS) is a recently introduced method for specific measurement, in vivo, of water in the skin. In the present study the method proved well suited to register the increase in water content in stratum corneum following application of emollients. The results were compared with those obtained with a commercial instrument, the Corneometer, and the two methods were found to match very closely. Neither method indicated any difference in hydration of normal skin between young and elderly women. Evaporimetry was used to detect any influence on the water barrier function of the skin following application of emollients; even though the water content of the skin was significantly higher after emollient treatment, the transepidermal water loss remained unchanged.
光热红外光谱法（OTIS）是一种最近推出的用于在体内特异性测量皮肤水分的方法。在本研究中，该方法被证明非常适合记录润肤剂应用后角质层水分含量的增加。将结果与使用商业仪器角质计获得的结果进行比较，发现这两种方法非常吻合。两种方法均未显示年轻女性和老年女性正常皮肤的水合作用有任何差异。使用蒸发测定法检测润肤剂应用后对皮肤水屏障功能的任何影响；尽管润肤剂处理后皮肤的水分含量显著更高，但经表皮水分流失保持不变。
