A little flimsy but goodVery nice mask, easy to use. Lots of options!I was somewhat skeptical before I purchase.I have been using this 7 Led Light Therapy Facial Skin Care Mask my face and neck every other day. I use the Red light to help collagen production and skin tone to help rejuvenate.I only used 7 Led Light Therapy Facial Skin Care Mask about a month but already feel notice improvement of my skin condition. I feel like to I am rejuvenated. I am confident that I am not using any dangerous chemicals.I am very happy with my purchase.After reading a few researches that confirmed efficiency of using specifically blue and red LED light on skin cells, I started to look for an LED mask.I read tons of reviews for different masks, but coming back to basics- LED is LED and more or less they will be the same, so I decided to give the INPUSLIN mask a try.The mask arrived quickly (God bless Amazon Prime!), it was packed very well and the box itself is a good storage solution for the mask. The mask size is universal and I think it will fit any face, the adjustable band is great and not too loose or too tight.I use it every day for at least a month (15 min of red light in the morning and 15 of blue light at night). It‘s too early to see the significant results, but I can confirm, my skin is less sensitive and less dehydrated, my face cleared from breakouts and the pigmentation from the previous ones almost faded.Overall, I'm happy with the purchase and can definitely recommend giving this mask a try.have been using for 15 minutes every other day.It‘s a great produce and also see results.It got rid of some of my acne scarsExactly what my skin needed. Perfect purchase!
