I used a different variation of this which I just recently ran out of, and I really liked it. I feel like it works well because I’m 29 and I started getting creases on my forehead when I was 25, and four years later they’ve barely gotten worse. Anti aging skin care is about prevention not reversal, so I feel like you have to trust that it’s working because the results won’t always be something you can see since it’s preventing wrinkles from progressing as quickly, and there’s really no way to know for certain how many wrinkles you would have if you didn’t use this product, but I feel like it has slowed progression and it’s kept the lines around my eyes from getting worse as well. It also helps with my skins redness and makes the area under my eyes really bright. It’s very expensive, but you get a lot and it lasts a while. The bottle I had before was over 3 ounces and it lasted me about 2 years with continuous daily use, so even though it’s expensive, it does last. When I skip using this product I notice my skin feels a lot dryer, and my moisturizer doesn’t absorb as well. It feels luxurious when I apply it to my face, my skin loves it. I don’t typically go for such expensive skin care products, but this is one that I would gladly keep as a staple product in my lineup.
