a little bit of this magical serum goes a long way. I've tried all the Lotus Wei serums and find this one to be the strongest and longest-lasting. Just a few drops massaged into my pulse points or massaged onto my feet before bed is incredibly soothing. This is great to have on hand if you're having a rough week or anticipating a lot of stress coming up, you can massage it on your wrists and arms and breath in several times a day or just use to give yourself a neck massage before bed. The bottle lasts a long time so don't be discouraged by the price.
