Are there any laser clinics in UK or my area in west Yorkshire that treat hemosiderin on the face with QP switched lasers?

Had fillers on my mouth corners in the past and they hit blood vessels resulting in a brownish greenish stain under my skin (hemosiderin) had it for months now and cover it up with makeup. I've heard it can be treated with q switched lasers? Been to several clinics in my area but all say they are not qualified for that sort of treatment. Question is who is? And where do I go? Iam in the UK in the Yorkshire area. Any help please or advice?
