What does it do?

Ratings & Reviews

Just try it


This is one of those products that's worth the money for the trial size to see if it will work for you. I'm really surprised by any review less than five stars. This is a superstar, holy grail product. It's a real magic bullet. It diminishes post-acne redness visibly overnight and disappears cystic zits like a mob hit. Ive also had success with brown spots, but I have fair skin and medium-brown spots. It's also really improved my crows feet. I use a tube until it's gone, forget about it a few months, and when I remember to buy it again it's like Christmas for my face. It brightens, plumps, fades redness, shrikes zits and smooths over NIGHT.

This product delivers on its promise. It will break up dark spots of HYPERPIGMENTATION from past blemishes, sun spots, melasma. 3 SUGGESTIONS BELOW: Use everyday, every other week, under sunscreen. See the difference in 1 month. Use it as a spot treatment. Apply toner with fingers, then take 1/2 pea size of this and dot it on problem areas, use slip from toner to spread it around entire face! Can you say "BRIGHTENER"?! Be creative, create your own way of using this wonderfully formulated product!

Healed Picked Acne Overnight!


No, you shouldn't pick at acne. Of course you shouldn't. No one should. But everyone does at some point, and if you're anything like me, you regret it immediately. I was using this for age spots (which it has worked well for, as long as I keep using my sunscreen daily), and accidentally put some on a picked spot. Woke up in the morning and the skin was HEALED. Still a little red and tender, but holy cow! HEALED. Fresh baby skin. I was amazed and thrilled. I'm not saying go crazy picking at your face, but I have begun using this along with PC's wonderful BHA products on any acne that pops up. And it helps the redness and helps heal it quickly. This is now a must have in my skincare routine. I'll take healing acne over diminishing age spots or wrinkles any day. So the fact that it also helps with age spots (can't say yet if it helps with wrinkles) is a huge plus. The only downside is cost. It's expensive! But it works!




Was my holy grail, but perhaps a formula change?


This was my go-to way to heal blemishes and calm them. I recently bought another tube and it is yellowy in color (it's always been white) and has a different consistency (drier than before) than previous tubes I've bought. It doesn't go on as smoothly or seem to be as effective. I am hoping this is a fluke batch/tube and I hope I can get another one with the original formula.

Sensitive skin and acne prone


I received a sample size of this product and I do feel like it works. It seems to be fading my acne marks that are still on the pink side (my acne lingers and can be stubborn to fade post marks). I don't know how effective this would be on darker marks. I am definitely using less concealer and foundation though the price point seems slightly high for a half ounce of product. I am also a budget shopper so that's just my opinion. If you have any freshly broken skin it does burn momentarily, but that doesn't bother me. Also I can't confirm any change in wrinkles, I don't really have any except for a significant expression line on my forehead and fine lines under my eyes (which this product cannot be used on eyes). I feel like if your main concern is wrinkles a retinol cream would be a better choice. OVERALL I think this product is great for lighter acne marks, a bit expensive, and underrated. I am considering purchasing the full size.




Didn't do anything for me


Saw no brightening or lightening of spots. Would recommend other PC products in place of this.

Great for spot treatment


Love using this on my crows feet and specific areas. This is kind of a strange consistency but I would say as long as you aren't planning on putting this all over you will love it. Remember to pat not smear this. I really notice a difference when I use it on my wrinkles. I tried using this to brighten a dark spot and it worked well after a week or so.

I so wanted to love this....


...but sadly it burned like lava on my skin. Ouch! I will be returning.

works on acne...who knew?


I'm 47 with dry skin that still breaks out occasionally (nose/t-zone) area. I've used the full suite of Paula products for about 10 years and while I occasionally dabble in another line, I'm loyal to the results I've experienced. I received a sample tube of this and tried it out on a couple of little acne scars. No change to the scar tissue itself but over several weeks redness faded. I used a little on a pimple that popped up on my nose overnight and was suprised that it flattened and then disappeared the same day. Since then I've used this as a go to product on little breakouts and it is very effective.

Magical. Like a gift from my Fairy Godmother


I've had frustrating, oily, blemish-prone skin since my early teens and nothing has ever fixed it. Doctors, Dermatologists, $100 a bottle exfoliants, etc., until I ordered a full routine's worth of products from Paula's Choice, I've never felt that I didn't have terrible skin. After two months my skin tone is much more even, I'm not having breakouts, my face doesn't feel gross and oily AND the damaged collagen on my nose (that "dent" in your skin that lingers after a pimple is gone, which drove me INSANE) is barely visible. From the reading I've done, I think the Vitamin C treatment had a lot to do with that, but more than anything I just want to suggest doing your whole routine with Paula's Choice. I use the Oil-Reducing Cleanser, 2% BHA Exfoliant, this treatment and Invisible Finish Moisture Gel. I'm about to order more of this, some toner and something with SPF. Thanks PC, you're the best!!
