The above two photos show the results of the above 532nm shots after 24 hours. There is some very mild erythema due to some of the capillaries being ruptured by this wavelength.
In summary, frosting occurs on both ink particles and melanocytes/melanosomes in the epidermis. It is more apparent in darker skins. Plus, it occurs more frequently with the lower wavelengths due to higher melanin absorption.
I should also point out that the 532nm is strongly absorbed in blood too! This can lead to damage in the superficial capillaries. I wrote a Research Letter about this phenomenon too.
