Body Pigmentation Due to Sunburns

So last month, I went outside for the first time due to some work. I did apply sunscreen and even reapply every two hours. I somehow ended up with sunburn on my legs. I noticed this morning that my arms and legs are kinda dull and even noticed some pigmentation. I think this may be due to the sunburns. Could you guys please suggest good body lotions and serums with brightening properties.
