Which procedure should I get first? Laser (Sebaceous Hyperplasia ), Microdermabrasion..

I'm trying to improve the quality of skin. I have severe acne scaring, uneven skin tone, sun damage, and also sebaceous hyperplasia. I'm planning to get laser to remove the sebaceous hyperplasia, and microdermabrasion to improve my skin quality and rid my skin of the irregularities. Which procedure should I get first, and long in between should I wait. Thank you in advance for you expertise!
