What triggers the appearance of age spots?
Excessive exposure to sunlight and UV rays are some of the major contributors to the occurrence of brown spots, regardless of whether you like tanning without any sunscreen on or prefer using a tanning bed. There is nothing good about an intense UV exposure.
The more you like tanning, the quicker melanin appears in your body. Melanin is what you see when you spend some time in the sun, and it is ‘the thing’ that makes your skin dark and chocolatey.
Your tan will disappear, but you will see brown splotches on the very same skin areas that have been mostly exposed to sun. It is the melanin that has been overactive in these skin areas, and ugly age spots are the only result you will be left with.
