Please share your experience regarding freckles and blemishes.

I am a first-time mom who started parental leave this month. I have been feeling down since giving birth because of the freckles and blemishes appearing on my face, and now they are difficult to cover even with makeup. I haven't had time to take care of my skin because I was busy looking after my baby, but I want to try managing it before it's too late. Would consistent treatment at a dermatology clinic really help improve these freckles and blemishes? I would be very grateful if those who have genuinely resolved these issues—not just advertisements—could share some tips on what methods worked best for them. It is difficult enough just to go out, so choosing a clinic is really tough.
