TLDR Low-output laser irradiation can stimulate or inhibit biological processes depending on the dose.
The document explored the biostimulatory effects of low-output laser irradiation on biological systems, finding that it could influence hair growth in depilated mice, enhance bacterial phagocytosis by leukocytes, and affect wound healing. These effects were dose-dependent, with higher intensities potentially inhibiting rather than stimulating processes. The research also suggested that laser irradiation might have remote effects, possibly due to a circulatory active substance, and could synergistically impact the immune system.
