Self-treatment methods to improve dark spots

Since I haven't been applying sunscreen either,

At some point, wrinkles are wrinkles, and I am developing some spots or freckles on my face.

It's not serious, but I'm still worried.

Is there a way to treat skin issues at home without visiting a dermatologist?

If anyone has personally experienced using certain mask packs or applying creams and has seen positive results, please kindly share your advice.

I previously asked a question about skin damage caused by ultraviolet rays, but there are still no comments.

Thank you
