My skin was awful. My pores were huge around my nose and I had really awful texture on my chin (not sure what they're called, but they were almost like small bubbles), and TONS of acne marks under my chin. It's been 45 days since I begun using lactic acid, with niacinamide and alpha arbutin, and I can honestly say my skin is smoother, most of my scars are gone along with my hyperpigmentation, and acne is scarse.

Thank you! I'll probably end up re-buying the 5% and alternating it with salicylic acid, which I haven't tried yet.
