Are there any side effects to using Embr Wave?

What happens to your body while you're using Embr Wave?

Placing something cool or warm on your skin for an extended period of time could constrict or dilate the blood vessels underneath your skin causing a mild irritation and/or redness after extended use, depending on your skin's sensitivity.
This effect is harmless and temporary and will go away on its own after a period of time.
