I would highly suggest you see your dermatologist for a Tretinoin prescription if you haven't already done so. You won't see a dramatic change immediately but over time the difference is notable, especially where pores and texture are concerned. Microneedling is great but takes a while to show results (longer than it takes the skin to heal) and for me, the redness/peeling is quite dramatic. I've had the greatest success with occasional microneedling (sometimes with PRP)—I've now bought my own home-use machine from Owndoc.com but am yet to use it—along with regular Tretinoin usage, weekly or twice monthly use of my PMD, SUNSCREEN (on my face I use CosRX Shield Fit Green PA++++, Purito Centella Green Unscented, Skin Aqua Super Moisture, all of which I find non-irritating when my skin is extra sensitive from the drying and exfoliating treatments), and SIMPLE cleansing and moisturizing routine (Cetaphil, Hada labo hyluaronic acid and moisturizer, Cosrx snail mucin), with occasional fancy essences or treatments. I used to use P50 by Biologique along with a host of other products from them but found that to be less effective, more time consuming and more expensive than my current plan.
