How do you take care of your deeply tanned skin after playing in the water during the summer?

My skin got much darker than usual, probably because I was exposed to a lot of UV rays after visiting a water park recently. I applied sunscreen and reapplied it frequently, but I got more tanned than I expected, so I'm a bit upset. It seems like the skin tone on my arms and legs has darkened overall, not just my face, and my skin texture feels dry and rough.

I thought it would naturally return to normal over time, but the recovery seems slower than expected, so I'm worried about how to manage it. I'm wondering if consistently using whitening cosmetics helps, or if getting treatments or procedures at a dermatology clinic would be more effective.

For those of you who, like me, have experienced getting a severe sunburn after swimming in the summer, how did you regain your original skin tone? I am curious whether your skin improved with just home care, or if you received professional skin treatments. If you could share any effective skincare routines or tips you would recommend, it would be a huge help. 😊
