I had a sunburn and i started peeling it kind of stopped but some of my skin is tan and with white spots will it stay 4 ever?

It might: One thing that happens after years of sun exposure is the skin pigments irregularly. This means you can have dark and light spots.

Not likely: Sunburns with peeling often will leave the skin with pigment alterations. Unless the sunburn was very severe, it is unlikely that the pigment discrepancy will be permanent. However, to give your skin the best chance to return to normal, please wear spf 30+ sunscreen to the areas. Any sunlight exposure on skin with pigment alterations will make it more likely to be long lasting or permanent.
