How to do microneedling on my facial pores? (Photo)

I do not recommend micro-needling yourself. It is not simply about the depth of the needle, but how you treat and what you treat with. I recommend you visit an expert in your area for best results as doing it incorrectly may cause more severe scarring and worsen your issue. I hope this helps. Larry Nichter MD, MS, FACS

I don't recommend doing microneedling yourself. This type of treatment should be performed by a professional to get the best results. I recommend adding prp and lasers to microneedling treatments to improve outcomes. I recommend getting a formal evaluation with a cosmetic dermatologist. Best, Dr. Emer

You will gain more and be in a safer place if you see a dermatologist for pores. Creams can help, do not use 0.8 in your case as it make make your scar worse. If anything go for gentle 0.25 mm skin rolling or derma rolling. It may or may not help, but is certainly safer than 0.8 mm needling. Many lasers such as Picosure FOCUS, Fraxel etc.. as well as RF insulated microneedling can help. I choose a particular laser based upon the size of the pore, skin type of the patient, and expectations. I find that the most reliable method is with INFINI RF, micro needling using energy. This beats all my Fraxel lasers and chemical peel techniques. Very little downtime, and it is ideal for small to medium size pores. Fraxel 1927 comes in a close second in the high density setting if your skin type is light. Picosure FOCUS if you are Asian or ethnic in origin. 
Chemical peels such as TCA (70-100%) placed focally in the pores is an excellent treatment for large pores. Fully ablative laser are excellent, but the downtime is long. I use both erbium and CO2. Fractional CO2 medium density can work, but you require 3-6 sessions. More in the pore section in the web reference below. 

Pore size reduction treatments should be tailored according to the patient IMO.
