Instant Under-Eye Firming Serum - (Classic Formula) Under-Eye Bags Treatment for Puffiness, Lines, & Wrinkles - Wear With or Without Makeup - 3 Minute Results (0.23 oz)

Good for fixing eyes but top breaks off too easily

Works great when used very lightly. Too much product leaves noticeable residue. Bought several and will continue using.

I've been using this product for several years for job interviews, no sleep days or special occasions. It worked beautifully (if temporarily, 8 hours or so). They must have either changed the formulation or maybe it's because I ordered it off Amazon. It's almost as if it's diluted. I wanted to pour a bit into the old bottle so I can keep one at home and one in my purse. I could tell it was " runnier" than usual and this one from Amazon is not effective as the ones I've bought off the shelf. There is little difference in the under eye appearance. Prior bottles worked well. ( The 1st time I kept checking the mirror because I was so excited with how well it worked!) I can't even recommend one off the shelf because Walgreens was sold out today, so if they've changed it, I guess I'll never know as I'll try another similar product next time. I'm UPDATING :there was no "classic formula" sticker or mention on the box I received ( but is shown here on the picture of the product). This is deceptive imo. This might explain why this bottle has been ineffective. Can anyone help with where I could purchase the "classic formula" version of this product? It worked so well in the past and this may be the issue.

I have used Sudden Change on and off for several years. The reason I only gave it four stars was because it does not have a longer power that I would like to see. HOWEVER, I have tried at least four maybe five other similar products that do not perform near as well as Sudden Change does initially, so by contrast Sudden Change is ahead of them all. It comes in a small, durable container that easily slips into your pocket, so you can refresh your application when you are out. It surpasses the competitors I have tried by price, packaging and effectiveness.

Holy Wow. Context: 46(F), lost 60lbs, saggy bags with hooded eyes, no dark circles, light skin. I needed something that was more than a temporary drying solution for the saggy skin under my eyes that just looked terrible. I've tried LOTS of stuff. One time on vacation a shop in Hawaii was trying to sell some eye serum by doing free demos. Their stuff immediately fixed my eye skin. However, I was not going to spend $1200 for eye serum. So the hunt began for something comparable and affordable. When I put this stuff on, skin was immediately tightened. BUT it was SO tight that if I smiled I had horrible wrinkles. I decided to experiment. The instructions say you can mix it with makeup or wear alone and you can dab with moisten finger if you get white shadow. It also states it will improve the skin over time. So I used a wet beauty sponge to loosen my skin up so I could smile. The next day I mixed with my concealer (tarte shape tape). Honestly, it did nothing when mixed. So I cleaned the area and started over. This time I applied the serum and let it sit for about 30 minutes. Then applied concealer and blended with beauty blender. This worked MUCH better. What I've noticed in just 2 days is that there is a lasting effect. I have great hopes that continued use will do the trick. I'm also using a peptide eye cream for improving the elasticity. My advice is to apply at night before bed so you won't care about ugly wrinkles from moving your face. Then let it sit for a good 30min before applying a peptide cream. Again, if this reduces the immediate affect, it will still be working overnight and no one will see it. It may work with other foundations better but I haven't tried that. It just didn't work when mixing it with mine. Pictures: No filters applied! 1st is the before 2nd is immediately after first application 3rd is serum then concealer blended with wet beauty blender.

For the price, I honestly don't know how this product can be beat for under eye tightening. I simply put two-three drops on my finger and gently glide under my eye across from the inner to outer, and repeat for the other eye. The skin tightens very quickly and stays that way all day long. I have not had any problems with the product leaving any white residue. I typically apply a lot of moisturizer under my eyes at night and only apply very little in the morning. I use Sudden Change literally right before I walk out of the house, so any moisturizer I used under my eyes earlier that morning has long dried, and I have had no problems using it this way.

dropper separates from the bottle and you have to pry it off as it sticks to it.

Been using this for years, it works to tighten area under eyes but leaves a white powdery residue. So I use just a couple of drops in an eye serum & this helps with that.
