I've only tried this product in sample size, but I love the feeling. My skin feels smooth and plump. I love it, and will def. buy the full size. I'll update when I've used the full size for a while.

This product reminds me a lot of Dr. Denese's Hydroshield Serum. Unfortunately, the price tag on Dr. D's serum was just too much for me. I am glad I stumbled upon Paula's serum. It's a silicone-based serum that glides over the skin, moisturizes and is fortified with retinol. I've received a lot of compliments on my skin lately, and I definitely think this product is one of the reasons why. Highly recommend if you are looking for a moisturizing, retinol product.

I have already repurchased this product twice and always have a spare on hand! This is a very fluid retinol serum that really packs a punch without any irritation. After about four weeks, I noticed a huge difference in the texture and firmness of my skin. I use two pumps (I'm greedy, you don't actually need that much) after cleansing, toning, and exfoliating, and before moisturizing. Everything just looks more "plumped" up. Lately, I have been alternating it with Differin Gel for even more anti-aging/acne benefits. I did notice a slight purge when I started to use it, because it is retinol and it will do that sometimes. The acne quickly cleared, I was left with really beautiful skin. If you are sensitive to retinol, start slow, and alternate application nights, working your way up to every night. After about a month, you should see a difference!

I rated this dirt cheap because if Estee Lauder or Lancome sold this, it would probably sell for $100 to $120. This is part of my daily night routine and I believe, responsible for keeping me young looking and wrinkle free (along with my Paula's Choice sunscreen). This doesn't smell or burn and sinks into my skin in under a minute. I especially love how all of her products are cruelty free and environmentally friendly, however, the best part of her company is her customer service team. I've never seen anything like them before.

I love this serum. I actually don't use it on my face, although I have with no problems, but I use Differen so I don't need it. What I do use it for is my neck/chest and the back of my hands. It doesn't irritate and keeps them nice and moisturized, and smooth. It's much cheaper than many high-end retinol creams, and more effective than the Neutrogena retinol cream I used to use. I use it only at night.

Replaced my drugstore retinol product with this, and will never go back! Good concentration of retinol, sinks in easily, package is about as light & air proof as packaging can get. Loving the RESIST line. continued >>

I'm really enjoying the results from this stuff. But not being able to tell how much product is left is very frustrating. And, the bottle seems very large relative to the content. This also makes it tough for traveling. Bottom line: Product is great, but wouldn't it be possible to sell it in a travel size?

This is one of my favorite products. This is my first purchase and I know I will definitely have a long term relationship with this one.
I am only using this at nights.
I mix one pump of this and a small squirt of Skin Balancing Antioxidant Concentrate.
I do not care about the shiny finish because I am only using this strictly at nights.
My nightly routine: i) Earth Sourced Cleanser, ii) Skin Balancing Toner, iii) BHA 2% Liquid, iv) RESIST Skin Brightening Treatment v) RESIST Intensive Wrinkle-Repair Retinol Serum mixed with Skin Balancing Antioxidant Concentrate.
Result: healthier and younger skin.

Apply this super rich serum and within minutes you can see your skin appear smoother, more supple, and less wrinkled. I am on my second bottle and plan to never be without it. Truly, the first night I applied it I could see a dramatic difference in the texture of my skin upon awakening. While just wearing skin care products from my Paula's Choice line, I was browsing the cosmetic counters at a local department store and the sales associate stopped my to tell my how beautiful my skin looked. Now people, I have redness in some areas and old acne scars. But this serum immediately improved those flaws. The sales associate didn't even try to push her line of skincare on me, she just told me to keep using whatever I was using because it was making my 49 year old skin look so good!

If I could only keep one beauty product in my arsenal (and it is truly an arsenal), it would be this product.

I have dealt with rosacea for years and have done much to get it under control. The problem with rosacea is trying to find a product to limit wrinkling without exacerbating the redness. But this works!

I have used this serum for the past 9 months, every night after cleansing, toning and using a 1% BHA product. This product not only helps deter wrinkles, but makes my skin smooth, even-toned, blackhead and blemish free, too. It is fragrance free.

Start out slow with the product. Maybe use every other night for the first couple of weeks, then increase to every night. Don't use too much. A dime size is enough for your whole face and neck.

You might experience a little breaking out initially and I did too, but it is very temporary. Stick with it and it will clear up. Might be a good idea to start it during a good time in your "cycle" as many of us tend to blame products where it may just be our hormones.

The packaging is genius. No waste. Dispenses exactly the right amount and keeps the retinol stable. If you are looking at other retinol products, be sure their packaging is such that it keeps the retinol stable or you will be throwing out your money.

The cost is $30 for 1 oz. but it will last 4 months or more which is pretty cost effective compared to other retinol products. I am actually thinking about giving it as Christmas gifts to all the women I love this year because I think it is just that extraordinary!
