Has anyone tried using Meladuse Ampoule consistently?

I'm worried because my skin tone has become so dull lately that I'm afraid to look in the mirror. Recently, I went to a brightly lit cafe with some friends and took a selfie, and I was really surprised to see how blotchy my face looked. It wasn't this bad before, but I think it's time to start taking a more systematic approach to skincare. While researching, I came across the Meladuce Ampoule, which has many reviews and is popular with people like me who are concerned about blemishes. I wish I could make a difference just by applying it daily at home, but I'm curious to see how it actually feels. I have sensitive skin, so I prefer products that are gentle on the skin. How does the Meladuce Ampoule feel? I'd also like to see if it absorbs well without leaving a sticky residue. I'm thinking about stocking up on a few bottles and using it intensively for a month. If anyone has seen any results from this product or is dealing with a similar issue, could you share some advice?
