A sign that once appears, it does not disappear

A sign that once appears, it does not disappear

It's quite notorious, you know.ㅠ.ㅠ

I didn't understand the importance of sunscreen when I was young, so I often went around without any face protection;;;

Now, only one or two are starting to show up in my body.

Not to mention the arm freckles.

Now I can see the slight swelling spreading on the cheekbone.

I hear that melasma is difficult even in dermatology, so I get a bit scared.

Does applying something like Domina cream definitely lighten dark spots?
