Freckles are hereditary, and your condition is typical of hereditary freckles. It's not too late to treat freckles. Although the sooner you treat them, the better, you can't treat them under 18 years old, because your freckles haven't fully grown, and it's easy to recur in the future. I suggest you go to the hospital for face-to-face consultation. There is a good beauty hospital on Heping Road in Jinan. You can try. I think it's called Jinan Airong, I don't remember. Good luck.
