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).

Seemed to work the first time only
SampledPurchased

I loved the sample I received in my box. It seemed to work well and magically made my pores smaller or my acne disappear overnight. But when I purchased the full sized product, I was disappointed. It isn't working as well as I thought the sample did. I'm not noticing any difference to my skin after application.

Trying to really love it...
Purchased

It seems to contain some magic potion but not enough to go deep and help with cystic acne. I haven't noticed major differences with my scars but is has helped some smaller spots/pimples.

My absolute fav Paula Choice product!
SampledPurchased

A dab is all it takes! I apply to a few red splotches and (gasp) sun-spots on my face & décolletage and it has done wonders in reducing not only the persistent redness, but has faded the sun-spots significantly! It takes very little product to make a big difference, so I am stingy with it. I do apply it to the back of my hand and even remaining product gets rubbed in on the back of my hand, which has remarkably lightened some sun-spots there as well! Win-Win!
The cost might be oft-putting to some, but again, a little goes a long way and the results justify the costs. My husband uses it for skin-irrations and age-related spots & now he's hooked on it too, and he never cottons to any beauty or age-related type products!

Miracle Worker
SampledPurchased

When you are a teen getting acme sucks, but it is even worse when you are an adult. This is one serious miracle worker! Put it on at night and abracadaba your skin is once again free and clear by the next morning. Everyone should have this in their bathroom for those acme emergencies.

Best thing that has EVER happened to my skin!
Purchased

Paula's Choice Resist BHA 9 performs wizardry on my skin.

I have had nearly constant and painful cystic acne on my chin since I was a teen. I've tried medications, treatments, pretty much everything and nothing has worked as well or as quickly as this!

My skin is breakout free. My scars are visibly lightened and some have faded away completely after only 4 weeks of use- we're talking years old scars GONE.

I mean, seriously, wow. This stuff is a life changer for me and I am so glad to have found it!

Works wonders
Purchased

I have several "spots" that were deeply imbedded blackheads, that would not be dissolved or extracted. I applied this for a week and was able to extract them after using some hot compresses. Even better, they have not returned! I now use it daily on my t-zone to prevent problems.

Wish it was cheaper and bigger
Purchased

So maybe I'm a cheapo. I would have given it 5 stars if it were slightly larger and slightly less expensive. I love it because it works. It has definitely taken care of the trouble acne/bump spots on my face. It has made my skin better by letting deep things surface and finally clear up for good. It is perfect for those with some trouble spots. I use it for my chin area mainly.

Noticed a difference in acne scars
Purchased

A little goes a long way with this product, and after using it for a few months (a few nights a week) in combination with Vasanti Brighten Up, I definitely notice a positive improvement in my skin's complexion and tone.

Not great results
Sampled

I have acne scars that I have tried many products on and they all kind of work- this product was another example of this partially works but is no miracle cure.

Waste of Money
Purchased

Did not do as promised. This is very expensive and I have two tiny red spots I was hoping this product would help with.. all it did was dry out my skin and did not help the red marks. Waste of money.
