Can I ask those who have tried the Meladuce Ampoule some advice?

Last weekend, I went to a beautiful brunch cafe with some friends for the first time in a while, and I was really shocked when I saw the photos I took there. Maybe it was because of the bright lighting, but blemishes on my skin that I hadn't noticed before were more prominent, and my complexion looked dull overall. I think it was a turning point for me, as I've been in my mid-20s, that I've come to realize the importance of skin tone management. So, I was looking for whitening products and came across Meladuce Ampoule. I'd heard rumors that it had good ingredients and good reviews. Honestly, I have sensitive skin, so any product I use can easily cause my skin to redden, which worries me. I've been desperately looking for a whitening product that I can use consistently without irritation, and Meladuce Ampoule. I've been wondering if it'll work for me, so I've put it in my shopping cart and am just contemplating. I used to be able to just apply whatever I wanted, but now I'm really careful about even choosing my basic skincare. If anyone has purchased and used the Meladuce Ampoule, could you share your experience? I'm especially curious about whether it won't smudge or look cakey, especially if I apply it before makeup in the morning. Or, if you have a special skin-brightening routine that only you know about, could you recommend it?
