What fitzpatrick skin types are more likely to experience darkening after a laser treatment? Why is this?

Fitzpatrick types 4, 5 and 6 are at risk. Individuals with darker skin have more active melanocytes that are more easily stimulated, ,whether by trauma or sunlight. This is shown by their propensity to tan when exposed to ultra-violet light. Lighter-complexioned individuals do not have this same propensity.
