Yea so like everything Jes makes, the Yarrow Serum is 6 out of 5 stars. Maybe 7; I think seven stars are appropriate. Is it the love grown ingredients or the love being combined with nature’s wisdom that blooms forth this offering for healing and repair? Gee, I dunno! Fortunately for you and me knowing why this is the Bee’s Knees isnt gonna affect thee facts- the knees are loaded with cosmic pollen from the Flowers of Pure Rainbow Light. That would be hippy speak for “it just works, my fond feathered friend!” Did I mention I’m an Owl? Owl’s the name and I have emerald fir powers so, you could do well to listen to this wisdom. Yarrow Beauuuty Serum is one of my favorite plantmakeup products. Love!
