I would appreciate it if you could recommend a skin ampoule^^

Hello. I am a male office worker.

I've been so negligent about taking care of my skin that I can clearly feel that my skin tone has darkened and lost a lot of elasticity...ㅠㅠ

I'm trying to find some good nutritional supplements now, but no matter how much I search for articles recommending skin ampoules, the terminology is difficult and I don't know which ones are good.

If you could recommend a skin ampoule that is not sticky and has good absorption, even a beginner like me would trust it and try it.

Please recommend a good skin ampoule^^
