Recommendations for effective procedures to brighten your overall facial tone

Perhaps because I have been exposed to strong sunlight a lot recently, my face has gotten very tanned, and my overall skin tone has become dark and dull. I want to get back to having white and clear skin, Which procedure is most effective for improving skin tone? I am considering a procedure like a toning laser, I am wondering how many times I need to manage this consistently to see results. In addition to UV protection, please let me know if there are any special skincare tips I should pay attention to for skin tone improvement after the procedure. I would appreciate it if you could recommend some good ways to get rid of my dull impression. Whether there is any significant inconvenience in daily life while undergoing the procedure, I would also like to know if the effects appear gradually. I will schedule a consultation for a quick tone-up effect.
