Every time I look in the mirror, I worry about my dull skin tone. Meladuse Ampoule

Yesterday, I ran into a friend from high school for the first time in ages, and I couldn't understand why my face looked so dull under the cafe lights. My friend's skin was still clear and clear, but I looked particularly tired, which was frustrating. When I got home and looked closely in the mirror, I noticed that fine blemishes that weren't visible before had started to appear. I realized I really needed to take care of my skin. So, I searched online forums and social media, and I came across quite a few recommendations for the Meladuce Ampoule, saying it helps improve skin tone. Honestly, I'm a bit of a procrastinator, so I can't stick to complex skincare routines. I was wondering if applying even just one Meladuce Ampoule every day would brighten my complexion. My skin is a bit sensitive, so I'm a bit worried it might sting or irritate my skin. Has anyone here actually used the Meladuce Ampoule for an extended period of time? I'd like to hear your honest opinion on how it spreads and whether it's a good product for daily use.
