对低功率激光的皮肤透过率进行了体外研究。He-Ne激光和红外线激光的穿透只观察到了几毫米。在0.4 mm和0.5 mm深度观察到最重要的吸收。这些结果表明，真皮血管丛屏障似乎减少了该水平的穿透。这一发现应该意味着激光疗法对深层组织并没有真正直接的影响。然而，这种影响可以通过许多不同的途径进行调节。
The skin transmittance for low power laser light was studied in vitro. The penetration of both He-Ne and infra-red lasers was observed for only a few millimeters. The most important absorption was observed at the depth level of 0.4 and 0.5 mm. These results suggested that the dermal vascular plexus barrier seemed to decrease the penetration at that level. This finding should mean that the laser therapy did not have really direct effects on the deep tissues. However, the effects can be mediated by many different pathways.
