Is care for vertically sagging pores effective? I would like to inquire about the cost and who it is recommended for.

Now that I am in my mid-to-late 30s, my skin elasticity is definitely not what it used to be. The pores on my cheeks have stretched vertically, making the texture look very rough. Since these changes are caused by a loss of elasticity, simple cleansers aren't enough to resolve them, so I am currently looking into getting professional pore care treatments. I’ve heard that these treatments replenish collagen from within to tighten the outer surface, so I would like to ask for advice on whether this is the right recommendation for firming sagging skin caused by aging, like mine. Since I am juggling work and childcare, frequent visits are difficult, so I really want to receive proper care when I do go. I am curious about the approximate cost of a single pore care session for the entire face. I look forward to hearing the opinions of those who have experienced this.
