You may want to consider a picosecond laser like PicoSure. Picosecond lasers deliver a strong pulse of energy over a very short picosecond interval to scatter pigmentation without heating up the skin significantly.
In my opinion, PicoSure is a good choice for treatment of pigmentation like freckles and it is the gold standard to effectively and safely treat facial pigmentation.
