Blackheads? Gone. Dry flakes? Gone. Nose? Smooth. Clogged pores who? My skin tends to be sensitive at times but it could easily handle this product.

The first night I used Paula’s choice exfoliant just once, it cleaned up my skin scraping it whole, I was left GLOWING but it felt kind of tight like I had been using corsx salicylic acid for 3 days straight, it takes some getting used to, to the extent that the instructions literally say to start off once a week and slowly build your usage up overtime, it’s really strong but does the job well. I’ve noticed that if I overuse it, I get extremely coarse skin and whiteheads slowly appear in the places I use it most (my nose). This is why I highly advise to purchase the small sample bottle first and to build your way up, at MOST every other day. I’ve used it 3-4 times a week since and on the few days I don’t I use a daily-friendly exfoliant toner pad so my skin barrier isn’t destroyed but bacteria doesn’t also build. It dries up all the forehead gunk, removes residue on the sides of my nose and dried up the pimples I had been trying to rid of for so long, my skin is left gleaming, exfoliated as ever, and I know my skin wouldn’t be as flawless without it. 30ml sample version Lasted 2 months from Dec-Feb used every other day. I now use the 118ml version since Feb and there’s plenty left, will most likely last for about 7 months and 3 weeks in total (based on how long i went through the sample size). As much as I love this I deeply suggest researching and sampling because there are mixed reviews of people claiming that it ruined their skin which doesn’t surprise me -since it is pretty harsh exfoliant and skin is diverse. I tend to be wary of western products but one thing western products do well is harsh exfoliants. If you have a lot of bacterial residue, sebaceous filaments and the feeling of gunk on your face even after your exfoliant, this is a good one to consider. This combined with my Needley daily Toner pad is the only reason why my forehead looks like a glazed doughnut
