Before treating skin, cleanse with Paula’s Choice RESIST Optimal Results Hydrating Cleanser.

Paula's Choice

Birchbox Breakdown

Some imperfections are endearing (think: Lauren Hutton's famous smile), but there are certain flaws we’d prefer to keep under wraps. Lucky for us, Paula’s Choice RESIST BHA 9 for Stubborn Imperfections tackles acne scars, rosacea, wrinkles, blemishes, and so much more.

How it Works

The all star in this flaw-killer is BHA 9, a unique ingredient that slowly releases small doses of skin-transforming salicylic acid long after your initial application. Best of all, the doses are so gentle your skin will reap all the positive benefits of salicylic acid without experiencing any dryness or irritation.

How to Use

At night, use as leave-on spot treatment, or with clean fingertips massage a very small amount of all over your complexion. Avoid contact with the eye area.

Propylene Glycol (solvent/penetration enhancer), PEG-75, PEG-8 (thickeners), Water, Salicylic Acid (beta hydroxy acid/time-released exfoliant, 9%), Glycerin (skin-repairing ingredient), Avena Sativa (Oat) Kernel Extract (anti-irritant), Butylene Glycol (slip agent), Boerhavia Diffusa Root Extract (antioxidant plant extract), Sea Whip Extract (soothing plant extract), Arginine (amino acid/skin-conditioning agent), Polysorbate 20 (stabilizer), Disodium EDTA (chelating agent).

Only used the sample size but it worked
Sampled

I did not buy this product due to price, but I loved the sample and it worked like a charm. If you have a lot of blemishes it might not be feasible to use this product due to cost, but if you get an occasional whopper this is a miracle. I used it on a giant red bump that apeared in the middle of my chin the day before an event, and it was essentially GONE in the morning. The redness was no longer visible and the bump was nearly flat. It was 100% concealable. I still have half my sample, I might purchase it if I had an upcoming wedding or something as an emergency back-up plan for zits.

Staying Power
Sampled

While this product does stay put fairly well, the texture actually seemed cakey which made wrinkles more obvious. I have used Paula's Choice in the past and really like their serum. I probably won't buy this but some may like it.

This is a skin saver!!

This stuff is magic! Any time I see a blemish start to form, I dab a tiny bit of this stuff on and WOW -- it prevents the blemish from growing and immediately starts to heal it--wham! gone in 3 days. I am amazed that this product works because any spot treatment I've ever used irritated/dried out the rest of my face. Also, yes the texture is a bit oily, but it is a nighttime treatment, so who cares? It hydrates the skin instead of making it flaky and dry! Definitely recommend this to anyone who gets the occasional spot!

So tiny
Sampled

I would have loved to test this out for a longer period of time. The tiny sample felt nice, but I don't have a good baseline for it.

Love this!

Love love love this product!! I apply this a couple times a week before bed and it really helps control my blackheads. I also love this for cystic acne and large pores. It's a great multipurpose product. Will definitely buy the full size!

Not sure yet

I have been using this at night for several days now and cannot tell the difference on my imperfections. Not sure if I need to use longer to start noticing...

Surprised

My mother in law gave me her sample. I had a cystic acne bump on my chin. I have very sensitive skin so I was worried about putting more oil on it but I used just a drop before bed and it was completely gone when I woke it it was like magic.

Pleasantly surprised
Sampled

I was skeptical at first, because so many products claim to fix skin problems. However, I was presently surprised by this. Stubborn bumps I had on my face shrank, and when a new zit popped up, I applied this product and it sped up the healing process.
