Do you have a daily routine that helps with skin whitening?

To brighten my skin, I am trying to apply sunscreen properly every morning, but

It seems like the blemishes on my skin are increasing every year.

I have a lot of dark spots under my eyes, too. I'm wondering if the sunscreen isn't working.

I was wondering if I should get laser treatment, but I heard that it can spread if done incorrectly.

I haven't tried laser treatment yet. My skin is sensitive, too.

So, I am working on inner beauty to make my skin's natural tone brighter.

It will take some time, though.

Do you have any good tips for whitening your skin?

If you have any, please share them.
