When is it safe to have PRP injections after using topical creams such as Hydraquionine Corticosteroid and kojic acid?

I am on topical cream consisting of Hydraquionine Corticosteroid and kojic acid and using this at night for 4 months for hyperpigmentation. I want to get PRP injections under eyes and on other areas of face and I want to do cosmetic tattoo for eyeliner-top and bottom. Can I get these while using this cream. If not how long do I have to go off it before I get this treatment and when can I go back on it after? Or do I have to completely stop and for how long do I need to stop it for ?
