My skin is finally behaving!
I did have a purge for about two weeks. You can tell if your skin is purging if you're breaking out in the same places you usually break out. If you're breaking out in random places where you don't usually get acne, then you may be having a reaction.
I got a few spots, they came on quickly and disappeared quickly, mostly on my chin and jaw, where I usually break out. I hoped it was only purging and kept using the product, and yes! The spots stopped and now my skin stays smooth and clear! I even started using this on my "bacne." However, it is drying, and if I don't moisturize, I get ITCHY!
As with all AHA/BHA's moisturizing is important, as well as sun protection.
I'm so in love with this "toner" (I think it's also the equivalent of an exfoliant), I use it on my bikini line and underarms to keep my skin smooth, soft, and free of ingrown hairs.
Sometimes I get a little tingle, but not really a burn, and it doesn't irritate. Some sensitive and/or dry skin types may have some irritation.
I also have some seborrheic dermatitis and this didn't make it worse. I can't say for sure if it made it better, as I was using hydrocoritisone on the SD at the same time, but it at least didn't interfere or make it worse.
I use this after Cerave foaming cleanser, before Neutrogena Hydroboost moisturizer. Soon to incorporate an AHA serum, so I may need to adjust how frequently I use this toner (currently AM and PM).
Overall, I am impressed that such an inexpensive toner gave me such great results. Some sebaceous filaments look more clear, and pores look slightly smaller, but I know there's not a lot of hope for those things in my mid-30s, so I didn't expect this toner to magically fix that.
