When I was younger (about 2-3 year old) I had a lighter skin color and now I have a darker skin color ( currently 19 years old ). Now as a teen I have became conscious about my skin issues ( including sun tan). I have recently started using Sunscreen in the hope to get closer to my original skin tone but I don't want to keep any false expectation so I want to get an idea of What my original skin tone could be like i.e. my skin tone with minimal/subtle sun tan ?
I searched through internet to get the answer and found a convincing answer on Quora but I don't trust the source also the answer mentions some facts that I've never heard of so I'm posting this question here.
Here's the summary of the answer for a quick perusal:-
Most children born of darker skinned parents are lighter in color. Both because the melanocytes take some time (mostly) to really start working. Also after a while they stop protecting babies from the sun with a cloth, and let the sun change things. So I would say your ‘real’ color is what it was at six months of age. Of course, your sun tanned skin is not ‘unreal’ either, but it is different. I believe the six months of age answer is what you are looking for.
