Is good to add in the water of the bath for relaxing or for massages, and for clean your face using some cotton because is a sebum regulator (good for hair too, before shampooing). and a skin anti aging.
you can use lavandula spica, officinalis, latifolia, angustifolia, hybrida. dont use ornamental kind couse they dont smell too good.(and of course make shure you are not allergic to the plant)
