Review title is Much more than just hyaluronic acid! Very moisturizing and best fitting for my face. 5 stars⭐ [SEP] I love these masks! For the price and how many you get, I was surprised to find the plastic backing. I really like this, because I can open it up and make a few cuts using the plastic and its cutouts as my guide to make it easier. I cut right through the plastic and the mask at the same time. I always have to cut a little slit at both the inner and outer corners of the eye openings, and also the outer corners of the mouth opening, as I like to move my mouth a bit and I have extremely dry eyes and the serum always gets into them, if I don't. This also lets it lay down flat on my nose and eyebrows better. I also cut four slits at about 10 and 2 o clock and 4:30 and 7:30, or roughly equal spacing coming upward diagonally from my eyes and coming down and outwards diagonally from the corners of my mouth. My face is a bit small, and this helps me to be able to overlap those areas and make them fit better, especially with larger masks. With these, I have to do the shallowest cutting ever, because they fit so well. They cover my entire face better than any mask I've used. I haven't had a problem with them lifting up or drying out at all. It also helps with something I will share later in my review.<br />It takes a little finagling, but I manage to squeeze a bit of the serum off the mask while removing it from the package. I start before I even open the package by pushing all the serum to the bottom. I cut the top open, grab the top of the Mask, and fold the sides of the package inward, almost in half, using my non-dominant hand. I start pulling out the mask while squeezing the top closed around it as best I can. This squeezes out a good bit of the way too much extra serum that comes out if I don't do this.<br />I love hyaluronic acid, but these masks have so many more wonderful ingredients than just that. Almost every ingredient is so nutrient-rich or moisturizing for the skin. I use Retin-A and these are the most soothing masks 1 to 2 days after my application nights, which are every 3 nights. These moisturize my face so well and they feel great while I have them on. I don't want to take them off when the timer goes off. There's plenty of serum in the package to use elsewhere, like on your neck & decollete, and even on your hands. I always put a moisturizer on afterwards to hold all the nutrients and moisture in properly.<br />I learned a trick while back from another reviewer that I've been doing since I read it. When taking a mask off my face, I cut it into 4 pieces. Mainly, I cut them apart at the forehead, cheeks, and chin areas, using the four diagonal cuts I made, but you can make the cuts as you wish. I usually discard the small pieces that cover the nose and upper lip. I then take those four pieces, put them back in the serum that's left in the package remoisten them, with these that is no problem, or just add a little hyaluronic acid serum to moisten them again, put them on my neck and decollete area the best I can, and wait another 15 or 20 minutes. This really lets me get the most possible use out of every mask.<br />I really love these masks and all of the skin loving ingredients they contain. They make my face feel wonderful afterwards and the effects last all day, if not longer. These are definitely on my must-have list. Highly recommend!
