Enlarged pores and freckles in your 40s...

After having children, I used taking care of them as an excuse not to take care of myself at all, and now my skin has completely fallen apart.
Where should I start managing this? ㅠㅠ haha

If I'm worried about freckles, I become worried about my pores, and then I become worried about skin elasticity again...

Sigh... Anyone else with the same problem, please help me out haha
