I'm worried because I can't tell the difference between melasma and blemishes.

Lately, I've noticed some kind of pigmentation mark on my cheek, but I can't tell if it's melasma or just a blemish, so I'm writing this post out of frustration.

I looked it up, and it says that melasma is caused by UV rays or hormones and has indistinct boundaries, while blemishes have more distinct boundaries. However, in my case, it is difficult to say exactly which one it is. The color is also on the lighter side, which makes it even more confusing.

I am also curious if the management methods or treatment approaches differ between these two. I read somewhere that Pico Toning is effective for melasma, but I am not sure if the same procedure is suitable for blemishes, or if a different approach is needed.

I suppose the right thing to do is go to a dermatologist and get a direct diagnosis, right? But I think the consultation would be easier if I went with some prior knowledge. If anyone has had similar concerns, please feel free to share how you handled it.
