Is Rejuvapen okay to use over active acne? Micro-needling?

I have an appointment for Rejuvapen soon. During the consultation, my doctor told me it would help with my acne scars along with the "active acne" I have now. I have a mixture of pustules and seborrheic dermatitis. After looking online, I have seen several people saying micro-needling will spread active acne and make it worse. Is this true?
