My nasolabial folds are a bit deep for my age; honestly, they look so bad in photos taken in dim lighting that I haven't wanted to take any pictures for a while ㅠㅠ I figured I’d just get a refund if it didn't work, so I bought it. After finishing the bottle, I took a photo and could actually see the lines looking lighter. When I look in the mirror, I wonder if it’s just the lighting, but it definitely feels like my foundation isn't creasing as much. I'm almost out and I'm definitely going to repurchase. If they had a bigger size, I’d be slathering it all over my neck too lol. Oh, the cap is a bit slippery, that's a downside.
