How Can I Remove White Sun Spots?

The issue you are describing can have multiple diagnosis and each can be treated differently. It would be important to be check by a Certified Dermatologies. Some of the causes can be treated but specifically White Sun Spots (idiopathic guttate hypomelanosis), its a very difficult problem to treat currently there is no good treatment for it. I would recommend to you to use sunscreen regularly, specially living in Florida to prevent that type of lesion or other to continue to affect you skin. 
Hope this helps,

Thank you for your question. Hypopigmentation from sun damage is challenging to treat. I would recommend consulting with a Board Certified Dermatologist for safest and best treatment options. I hope this helps.
