At first I balked at the price - $48 dollars is a lot for me to spend, and most of the Paula's Choice products cost less than this. But then I saw a similar product that SkinCeuticals offers for $162, and then this didn't seem so bad.

The product can be used alone but the instructions say you can add it to another moisturizer.

It does have a very light scent but to me it smells like crushed up vitamin C tablets, and nothing more offensive than that. If you add a masking fragrance to a product, you risk irritating the skin.

I am able to use this without irritation, but I don't use a ton of it at once. It is strong. I avoided it completely when I had a bad reaction to another product that contained menthol. You should sample it before buying if you have rosacea or eczema or any inflammatory condition, because it might be too much for you.

I use 3 or 4 drops, which is enough for one dose. With regular use, I noticed my freckles fading and it seemed to improve texture.

I bought a second bottle because I did see improvement from the first bottle.

Another texture-improving product she has is RESIST Intensive Repair Cream. It's marketed to dry skin but makes a good night cream. Retinol is the active ingredient in that, and it only costs $29, so that might be an option for you if this product doesn't ring your bell.

I try not to go overboard applying several products to my face at once, because I can't. I don't use two retinol products together and I try not to use two acne-fighting products on the same day, etc. I don't use an AHA and a BHA on the same day. I'll use a cleanser, a toner, then a treatment or moisturizer. For daytime I use a sunscreen and foundation, but not applied over lots of creams. I save the moisturizers for night unless my skin feels dry or itchy, and my need for a gel or cream depends a lot on temperature and humidity.

Unfortunately, this product didn't do anything for me. It came in a nice bottle, but that's about it. It smelled horrible and I am 99.9% of the time not offended by smells in skincare products. It reminded me of the smell of a sewer. This did nothing for me and might as well been putting plain water on my face. Actually, just water alone would have been better. I used the Paula's Choice Resist line exclusively for 6 months. It just dried out my skin even more and made it look so dull. The items I used were: Resist C15 Super Booster, Resist Cellular Day Moisturizer with spf 25, Resist Non-Greasy Moisturizer, Resist Wrinkle Repair Retinol serum, Skin Perfecting 2% BHA, Resist Toner, Resist Cleanser, Resist Foundation, Resist Daily Smoothing Treatment 5% AHA, Resist Weekly Resurfacing Treatment 10% AHA. With all of this, I not only saw no results, my skin looked worse. I like to enjoy my skincare. That is huge for me. These products bored me. I ended up throwing what wasn't used up in the garbage after giving it a good 6 months. In summary, they were so boring and ineffective. Fortunately, I am using new (NON-Paula's Choice) products now that have made a huge difference. I am enjoying my skincare routine again!

Tried it, used up the whole bottle (twice-daily usage), got no results, either short-term or long-term. For me, this was an utter waste of money. Short-term, it functioned no better than a basic serum with no active ingredients (e.g., it was mildly hydrating...and that's about it); long-term, the formula oxidized/degraded a bit and I probably should have stopped using it about 3/4's of the way into the bottle.

Perhaps I'm not the target market as I have no acne scars or spots/pigmentation from sun damage or any other major concerns besides general anti-aging. That said, I was hoping that it would improve the overall elasticity/texture/tone of my skin, which it didn't do in any identifiable way. I also didn't get the sense that it was at least acting in a preventative/prophylactic fashion.

Despite my disappointing personal experience, I did recommend this stuff to my mom, who has tons of sun damage (used to have all day tanning sessions in the '80s-'90s and it shows, alas). Don't know if she purchased it, but she's prolly a better candidate for benefiting from a Vitamin C product.

For me personally, still looking for a Vitamin C product that's effective. It supposed to be a great anti-aging ingredient, but still haven't found one that's effective on my skin, let alone worth the money.


-I've tried the DIY Vitamin C serum route before and despite having otherwise bulletproof skin, on at least two occasions developed mosquito bite-like welts on my skin (probably from powder that didn't fully dissolve even though I purchased cosmetics-grade, extra-fine Vitamin C powder online). C15 had no negative effects on my skin and in that regard, appears to be safe/well-formulated.

-May work well for people who have skin concerns that are a better fit for what Vit C promises to do. (Sun damage, hyper-pigmentation, scarring.)

-Mildy hydrating (but not worth $48 for 0.67oz of product).


-Very expensive (but not as much as other Vit C products out there).

-Did nothing for *my* skin. Maybe 10-20 years from now (I'm 38), this will be a great product for me. For now? This is a big nope. In all fairness, in terms of pigmentation/spots, my skin age (according to a computer-based imaging test performed by SK-II a few months ago) in this area is 22, and 28 overall. I don't really have a specific skincare concern that can be helped in a dramatic way by a product like this; that said, to repeat what I wrote above, I was at least hoping for some kind of overall improvement.

-To the best of my knowledge, strictly an online/direct order product, which makes returns a PITA, especially since I'm in a dense urban area and used to making returns in person. For *me* personally, the Paula's Choice line is becoming less and less of an overall bargain and is increasingly not worth the risk/hassle of ordering online. Too bad, because I remember when the brand used to feel like one of the most reasonably priced choices out there. Not so much anymore :(.

This gave me one of the worst contact dermatitis reactions of my life. What's worse is I have no idea what the offender was, but I'm guessing either the Ascorbic or Ferulic acid as I had never used them before. I can use SAP and MAP without issue, so I suppose I will be sticking with them from now on.

This product made my face feel like I had the worst sunburn ever. It was swollen and red for 3 days after the only time I ever used it. NEVER again. I am going back to Murads C products.

I'm a believer, this stuff rocks and my skin has never looked better. I have used several C serums and made my own. It is a bit pricey, about on par with Ole Henricksen Truth Serum, but not nearly as spendy as Skinceuticals. Paulas Choice C15 is quite thin and watery compared to other C serums, but it does such a great job it can be overlooked. My skin is much brighter, smoother, and healthy looking. I apply daily in the morning before sunscreen and after a few weeks my skin looks dramatically better. I will definitely repurchase this.

Pros - Mild to moderate brightening of the skin

Cons - Whoa, expensive! Also, it doesn't last long - so if you're not sure you're going to use it religiously, don't bother. You won't get through the bottle before it breaks down and becomes useless.

Instead, I am using their new 25% Vitamin C spot treatment. It's more expensive, but here's the thing - you don't have to use nearly as much. In fact, I only buy the sample size (19$).

The 25% spot treatment is stronger, more effective, and I enjoy the lotion texture compared to this product's watery texture.

I like paula's choice products, have several of them in my skincare routine. Unfortunately not this. I bought into the hype and purchased this during the sale for $45, usual price it retails for $65 I believe. The first few times I applied it, it seemed like a miracle and brightened my skin giving it a glow. I was really wowed and thought finally something that can rejuvenate my dull skin. However after the first couple of times, the effect seemed to have diminished and whether I apply this or not doesn't make a difference to my skin.

It probably works better on someone who needs help in fading acne scars or marks but I typically have clear skin, just dullness and dryness so this didn't help.

Not repurchasing, the good point though. I did not break out.

Just ran out of my second bottle and was incredibly sad. I typically don't try Vitamin C products because I'm more concerned with fine lines and pores than I am pigmentation. However PC anything, I will try at least once. I was pleasantly surprised with this, it stung a little bit, as many active products do, but I was able to tolerate twice daily application when mixing it with face oils. I eventually started applying it around my eye area too, which is when I truly fell in love. When using this at night, I woke up looking way more rested, the skin looked firmer, less puffy and fine lines were definitely minimized.
Definite repurchase.
