Best thing I never knew I needed
The bristles are so gentle and manage to get into every little crevice of your face, and the massage grooves on the back are excellent for helping to relieve tension in the face, relax you and help massage in any facial oils or moisturisers. The app is great, because it guides you through everything, and you can customise the intensity and how long you want each of your cleansing sessions to be. I also love that you can use it without the app, which makes it really handy in the shower.
I've noticed that since I started using the Luna 3, I'm getting much fewer clogged pores and pimples, and my skin just looks so much clearer and is so much softer than before. I would definitely recommend this to anyone and everyone who is thinking of getting one.
