Is there a way to improve skin pigmentation on my elbows, ankles, and knees?

 

 

 

I am worried because I have severe pigmentation in certain areas of my skin.

The knees, elbows, and ankles are particularly bad.

Because of the dark discoloration of the skin It's stressful.

Summer is coming soon, too.

If the skin on the body, not the face, is discolored like this, would it be difficult to save it?

I'm trying my best not to rest my arms on my elbows, but I don't know why my knees or ankles have gotten so dark.

At first, I thought it might be due to dead skin cells, so even though I washed diligently and applied lotion well, the color doesn't fade easily.
The surface of my skin feels rough to the touch. So, could this be due to some other cause rather than just simple discoloration?

Actually, others probably won't look closely at my elbows or knees, but

Still, when I look at my body, even small flaws seem bigger. So I can't help but be self-conscious about it.

Even though I make sure to apply sunscreen in the summer, it's still like this.

If I have severe hyperpigmentation like mine, how should I manage it?

Would applying something like a discoloration whitening cream really be effective?

Given the extent of the discoloration, I am also wondering if it can be improved with home care.

Or I'm also wondering if I need a procedure like a peel or laser treatment.

I want to know how to make it even a little bit lighter.
