I ‘ve been using tri-luma and kojic for 3 weeks on a dark spot, it’svery clear now, but I get the halo effect, it’s the second time this happens, before I’d been using it every day, and I stopped after 2 weeks when I see the halo effect, wait 1 month and the halo effect was gone so I continue with it but one other day instead. This time I don’t want to stop it but I don’t want the halo, can I reduce the use to 2 time per week just to maintaince and the Halo will disaapear? should stop it at all?
