Please tell me how to remove impurities!

Can you tell me an effective way to remove impurities?

It's just that, since last summer, I've been feeling like I've been getting a lot more freckles on my face.

Even after taking a photo, I have to edit it to remove any blemishes, so I am very nervous.

I would appreciate it if you could tell me about any treatments or cosmetics that remove blemishes.

Also, in fact, it would be best to prevent blemishes from forming in the first place before removing them...

It would also be great if you could tell me how to prevent blemishes from forming.
