In order to learn more about potential risk factors of low power millimeter waves, the in vitro effect of millimeter wave irradiation on epidermal keratinocytes by measuring chemokine release, heat shock protein production, determining cell viability, and gap junctional intercellular communication were studied.

No harmful effect of low power millimeter waves irradiation on both keratinocyte function and structure in vitro was detected. The data support the contention that low power millimeter waves irradiation in clinical practice is safe and without risk of induction of topical inflammatory reactions or cell damage in epidermal keratinocytes.
