Please recommend a skin ampoule.

I am very concerned because my skin texture is rough and feels like it has lost elasticity.

So I asked people around me for recommendations for skin ampoules, but there were so many different products that it wasn't easy to choose.

My skin type is combination with very dry skin. Are there any recommendations for a skin ampoule that provides moisture without being sticky?

I would like to know a list of recommended mild skin ampoules that can be used without irritation, especially on sensitive skin that changes with each seasonal change.

Could you recommend a skin ampoule that's both cost-effective and effective? I'll look forward to your response.
