Yes, it does. Same with those who suffered from chemical bleaching, eczema, or abnormal skin condition due to melanins, it may take a bit of time, but conditions tend to reset as the body resets.
Don't see the body's adaptation timeline as short term in days or weeks. Those timelines are merely the average from worldwide statistics. Try to think outside of the timelines according to your own body, or those similar to you. There are many cases with your skin sudden changes. Some got their skin recovered in weeks. Some went to months. Some rare ones went to years. But overall, the conditions reset.
My oldest son had something similar when he was a kid around 5 years old. Some kind of chemical reaction from the lotions we used, possibly a mix of an
ointment and 50SPF sunblock resulted in a white patch of skin preventing it from darken. It remained bleached for a few months. The outer edge started to darken over time, but the center remained bleached for a good year. It took us a good long while to comprehend the chemistry interaction before we could create a list of interactive chemicals for do's and don'ts. However, that doesn't apply to him any more after the age of 12.
But, my brother started to have something similar. He uses 50SPF sunblock, but at the same time, he has chemo drugs that suppresses the melanin from producing properly. He has patches of bleached skin all over this body.
Point to take home, as we aged or our body chemistry changes, the interaction of compounds, be natural or manmade, will influence our body as well. It can be internal or external. We just have to find solutions one step at a time.
