How should I manage dead skin cells?

Hello. I would like to ask for some advice regarding dead skin cells. Lately, I feel upset about my skin every time I look in the mirror, so I decided to leave a post.

As I get older, skin sagging is becoming more noticeable, and I'm losing elasticity around my eyes and mouth. On top of that, I'm worried because my pores seem to be getting wider. Lately, my makeup feels like it just sits on the surface, and my skin looks dry and rough. I've heard that as you age, you need to exfoliate well for cosmetics to absorb properly, and it's frustrating just looking at it. I feel like I really need to do something about it...

However, my skin has become thinner and drier than before, so I am cautious about using just any exfoliator, fearing it might actually irritate it. Are there any gentle, non-irritating exfoliation products suitable for middle-aged individuals like me who are experiencing decreased skin elasticity and concerns about enlarged pores?

I am seeking advice from those who know of products or skincare methods that can gently exfoliate while also providing hydration.
