The quick answer is: yes, absolutely, vitiligo does go away.
Of course the answer for you may be more complex. Vitiligo is an auto-immune disease and is not understood all that well. Progress is being made but a real understanding is still years away.
What we do know is that there are a variety of treatments that will repigment skin affected by vitiligo. UVB lightbox treatments, steroids and other pharmaceuticals are all viable vitiligo treatment options.
While these treatments are effective, they are generally temporary. There are no treatments that lead to a permanent cure, only temporary solutions.
Each person has to evaluate what is viable and best for them. Some people may not want to deal with the potential side effects of medical vitiligo treatments. Some people may not be able to afford medical vitiligo treatment. Some people may prefer natural vitiligo treatment.
Also, some people may not be able to get vitiligo to go away. Not everyone will be successful. I have found successful vitiligo treatments to be difficult to verify. It’s a frustrating process that everyone with vitiligo must go through.
Have you had success with getting vitiligo to go away?
