Hi! I have the same problem and I’m still experimenting with some things. I tried a sample of the belif eye bomb. It’s actually the first higher end eye cream I ever used. The sample was not enough to really know what the long term results are, but it really moisturized but I also experienced creasing still. I switched to the Olehenricksen Banana Bright Eye Cream. I got a mini sized one so it will last me a lot longer than the belif. So far I’ve used that morning and night for 4 days. Again, it does take longer than 4 days to see true results but I will say that overall my undereye area has been a little less puffy upon waking up. Hasn’t done much for the lines yet but I do like how it feels on my under eyes a little better than the belif. As far as brightening, I think people are under the impression that the banana coloring is what brightens. That might have something to do with it, but when you put it on your under eyes and pat it in, that color goes away and it doesn’t immediately brighten like a brightening color correcting makeup item. It soaks in really well. Overall I really like this eye cream because I feel like with continued use I’ll end up seeing the results I want. I really do. I don’t know if it helps with concealer application/appearance because after the eye cream soaks in I use Becca Anti-Fatigue Under Eye Primer before I put on makeup. I swear by this, because it’s very light, velvety once it hits your skin and really easy to apply. I don’t feel like I’m pulling on my skin when I’m rubbing it in like a lot of primers. THIS primer is what really helps with concealer for me. Also, it does smooth out the lines a little. Nothing crazy, but enough to make a difference. I can wear this after my eye cream and then not apply any makeup at all, and it still makes my under eyes look a lot better. Smoother and more awake. Also as it dries or soaks in, you feel a really nice cooling sensation which is an added bonus. Overall my concealer does look better but it’s not perfect. My eye bags are large and puffy with my lines located right under my bottom lashes and that area is harder to apply any cream or treatment to because it’s so close to the eye. My left eye is significantly puffier and darker than my right. Always has been, no matter what. No idea why. But even that left eye looks a little better lately. If you must set your under eyes with powder, BECCA Hydra-Mist Set & Refresh loose powder works the best for me. It’s made of 50% water believe it or not. It actually feels like you are putting something cold and wet on your face but it’s not wet. It’s a very fine and soft cold powder and the finish is beautiful. It doesn’t look powdery at all like a lot of powder and it doesn’t dry me out even more. I will say though, this works best if I don’t use it over my fine lines under my bottom lashes. It’s hard to not accidentally go up that high with it, but if you use a beauty blender and do it slowly you can be more accurate. It does settle into the lines if I do apply it on them but if I don’t apply it there, it really sets my concealer wonderfully. Doesn’t look dry at all. It truly is a hydrating powder! Everyone is different. Even though you and I have similar descriptions of our under eyes, these may or may not work for you but using these products, I’ve seen improvement. Hope that is helpful!! Good luck 💖
