Sodium Hydroxide is also known as lye or caustic soda. It is used to adjust the pH of products; many ingredients require a specific pH to be effective.

Learn more about WaterSalicylic Acid (also known as beta hydroxy acid or BHA) is one of the most well-known ingredients for treating skin that struggles with blackheads and acne. It helps to exfoliate both the skin's surface and pores, and also acts as an anti-inflammatory agent.
This multitasking property makes it a great ingredient for cleaning out pores, controlling oil production, and reducing inflammation.
Unlike AHAs which are water soluble, Salicylic Acid is oil soluble. This means that it's able to exfoliate the inside of pores and reduce blackheads.
Concentrations of 0.5-2% are recognized by the U.S. FDA as an over-the-counter topical acne product.
It can cause irritation and/or dryness if one's skin already has a compromised moisture barrier, so it's best to focus on repairing that before introducing a Salicylic Acid into your routine.
In general, Salicylic Acid is a great ingredient for oily acne-prone skin.
While salicylic acid does not increase sun-sensitivity, we still recommend wearing SPF.

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
I just started using it. Have used it for two nights straight and my closed comedones have reduced and my skin looks and feels better. Thanks for your advice on not using it too...
I just started using it. Have used it for two nights straight and my closed comedones have reduced and my skin looks and feels better. Thanks for your advice on not using it too frequently. I’m thinking of starting with only twice per week and using the Needly toner pad the rest of the days.

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.
