calming [SEP] this tool can be calming as you roll it over your face but it is not as effective as using a cooling gel i have used mine several times now and have left it in the fridge to keep it cool i use it with my own essential oils and it helps relieve my tension especially when it is stressful i just like the cooling gel better as it is more effective and longer lasting i would gift this though as it arrives in a nicely done package
