Ghk Cu Face Injection

Curious on how effective this is compared to what everyone else does. My Doctor Med Spa lady is giving me a treatment plan and Ghk Cu injection in the face once a week is one of the things apart of that plan. She tells me its more effective for acne scars, which im trying to treat along with active acne and she says it is perfectly safe. Thoughts? I dont yet know the dosing but assuming its smaller than what you would pin in your body.
