I work a manual job outdoors and this year I found myself really struggling with stiffness in my knuckles and the skin on the back of my hands was so dry, no hand cream was really helping at all. I bought these handy lights hoping it might help a bit and was blown away by my results. I used morning noon and night and in no time at the stiffness in my knuckles eased and my skin softened. The warmth from the mitts is just the perfect temperature, not too hot at all. I also use the green lights on my décolleté to help with some age spots I have there. These have been a godsend for me and I wouldn’t be without them now, I highly recommend these mitts to anyone without hesitation.
