Self-tanning cream before hair transplant?

Hi doctors! Sorry for my english,Few days ago i did a hair tranplant (FUE), Two days before the surgery, i used a self tanning cream on my face and very probably a little of the cream touched the beginning of my recipient area. The day before of the surgery i did shampoo and the day of the surgery the clinic did another disinfectant shampoo.However i am scared... Can self tanning cream be persisted on my recipient area and to obstruct the hair growth and the engraftment?
