I love this! It’s lightweight and so so easy to use. I’ve been using it every night with cream on my face and I notice the difference already. It’s a great quality product and the instructions are easy to follow. The Meilen Beauty is part of my night time ritual now. It’s also really relaxing. The different colours are for different intensities. It’s small and lightweight so you can take it with you if you travel. My skin feels cleaner and smoother.
