I purchased this Parafaciem Mask mainly to help with my jowl area and to try to change the shape of my lower face by using it at night but since then I also had fillers done of this same area and I used the mask to help with forming and swelling and it did help. I can’t guarantee it will work for everyone but for me, it did help. By the way, I read some reviews that the masks smell and they dont. I washed mine in the washer and mine have no smell.The head piece was easy to place on; not complicated.I have used it for 6 months and see a difference in my chin… the excess fat and sag are going away. I love it!!!!I noticed a change in about 5 days so I will continue to use it. One thing that is a problem is several times my hair got stuck in the Velcro and I struggled to get it untangled. Now I am more careful...I bought the parafaciem lifting bandage, and feel like it is working well for me. I purchased it because I have to wear a cpap mask and needed a chin strap to keep my mouth closed. I like the the idea lf a slim chin line and to prevent my neck from getting saggy. I thought that it would be a beauty bonus if it could perform both functions for me. So far, I feel comfortable sleeping in the chin strap, its easy to wear and comfortable, and its working for my cpap therapy too. I'm very happy with this purchase and will continue to wear it and look forward to the beauty benefits too.I bought the 2 pack & gifted one to my mom! The price is very reasonable! We both have been using for about 3 weeks & really like the results! I wear mine over night! It is not uncomfortable to me & the material is breathable! I can feel it pulling/retraining my up! My favorite part is that it’s reusable! I’m glad I decided we to go with this one versus the a box of single use kind for the same price!So far, it seems to be working. I put it on wrong the first 2 nights then decided to try putting the curved side toward the throat and it was much more comfortable. Not sure if I missed that somewhere in the instructions. Others complained of it getting caught in their hair but I haven't had that problem.I received the Reusable V Line Mask Facial Slimming Strap a few weeks ago and have already noticed results on my double chin area. I plan to keep using the mask/strap overnight for the next few months to see if I can notice these changes on a permanent basis. I'll come back and update my review with how it goes! Thanks, ParaFaciem!Worked wonderful.
