Please recommend a skin ampoule!!

My skin has been looking dull and dull lately, which has been a concern. Can anyone recommend a good skin ampoule? I'm planning to completely revamp my basics with a skin ampoule that's suited to my skin type. If you have any recommendations for skin ampoules that you've personally used and found effective for improving dryness and elasticity, please share them with us! I'd appreciate it if you could share the ingredients and how they spread easily.
