Abstract
The application of laser in dermatology and skin therapy is a key issue for numerous developments in future. The helium-neon laser at 632.8nm wavelengths, with the power of 2 and 1.31 mW was applied on the mouse's skin at various time 10, 20 and 30 min for 20 days. The animals were divided into two groups; control group, which didn't radiate while the other group was divided in to three groups each one has two mice where it exposed to the laser. The histological analysis was used only for those groups and studied microscopically. Histological analysis showed a significant effect of laser and numerous differences between the two groups. The thicknesses of the epidermis layer for the control group comparing with other groups showed noticeable increasing. In addition the skin presents enhancing of the features and architecture of layers. So, the low power laser has a good effect and amazing tool to enhance skin layer and cells on it.
