Is there a special way to whiten skin?

When celebrities debut, their faces are obviously dark and country-like, but after they become successful(?), they have fair and beautiful skin tones.

Celebrities say they care about their inner beauty during interviews, but does inner beauty really help whiten skin?

I'll get dermatological treatment, but no matter how good the technology is, I'm curious about what exactly makes my skin whiter.

I never worried about my skin tone, but at some point, my complexion got darker and the area under my eyes got darker, so my overall face tone got darker. To cover it up, I had to use thick makeup, and the border between my face and neck became more unsightly. So, I started searching for ways to make my skin whiter.

I have friends around me who have transparent skin, and I think they were born that way. They don't understand me searching for ways to make their skin whiter. They say they don't even pay special attention to cosmetics.

While some people find the sexy style appealing on darker skin tones, I personally prefer fairer skin. Today, I was searching diligently for ways to whiten my skin, and ended up here, leaving a question. ㅜㅜ
