I love the light texture and it's perfect for summers in Arizona. It makes my skin soft without adding a heavy or greasy feeling. I love all the anti-oxidants in it but I'm not so fond of the niacinamide. I know it works and it's the favorite of many companies like Olay but it makes my skin flush. Not so much in this in this product, which is why I gave it 4 stars plus it's light enough not to make me break out.

This is a great product for daytime use for all skin types because it goes on like a fluid and absorbs easily without a greasy feel which is perfect under a moisturizer. I use the other resist antioxidant at night. The combination of these products with religious daily use has transformed my skin. I truly can not say enough good things about Paula's skin care line. I have turned on multiple family and friends to this line and they too are becoming believers.

A lovely product, does not break me out, works well with my oily skin, and easy to use and handle. I use it on my decolletage as well as all the products I use for my face regimen.

This serum is excellent for my difficult 40 yr old combination, sun-damaged, acne prone skin. It heals acne, fades scars and smooths my skin. Love!

Very light in texture and wonderful under sunscreen. Disappears into skin and feels like nothing is on.

This is the serum I've always needed and wanted - it has faded all of my red marks, restored clarity to my skin, and normalizes my oily skin all at the same time! The texture is SO amazing as well. I'm 22 and I can definitely see myself using this for decades to come. Thank you so much Paula!

I have finally found it! I have tried just about every Paula's serum and moisturizer over the last year and they all either burned my skin or caused breakouts. I have combination, sensitive, acne prone skin with mild rosacea (yeah FUN)! This serum is so light and absorbs really well. My face is left matte, soft and more even toned. It doesn't bother my rosacea or cause breakouts. I am on my second tube and am starting to see improvement in my fine lines too! DON'T EVER STOP MAKING THIS!!

I really like that this product does not leave a greasy feel to my skin, especially because I apply moisturizers after. What I am finding though is that the serum leaks into the lid so that each time I open it product drips out onto the counter. I think that the hole is too big in the tip of the tube. A bit disappointing - not sure if I would purchase again.

Was using Clinique Prep & Prime Brightening Serum which gets the best rating on Beautypedia. Really liked it, also a very light weight serum. Didn't think it could be improved on. I always try new PC products if right for my skin type, so I gave this one a whirl. Freaking amazing! I had little bumps around the corners of my lips & the top of my forehead that I figured were just part of my skin. This serum cleared them right up. This was the only change to my regime. Great product.

I love this product! I use it before I go to bed and under make-up during the day (about a week now). It does not make my super sensitive skin breakout, which is a plus. It's lightweight and soaks in fast. My skin looks better than it has in years, my acne scars have diminished and the deep wrinkle on my forehead isn't as deep as it used to be. This will definitely be a staple in my line-up.

This is a very nice serum and has a nice texture. The only thing I found was that it left a yellow film on my skin. My bf asked if I had eaten mustard and that I must have forgotten to wipe my face, lol! Not sure if it is due to the way I applied the serum or not?

This product is so smooth, soaks in great and doesn't have that silicone feel. If you haven't tried it, please do.

I have been using this serum for about a week and although that is not enough time to review its efficacy, I can comment on its texture. The serum truly is ULTRA light and sinks into skin immediately, almost like there's nothing there at all. But it sinks in so fast and so well that I don't even know where I put product. I'll get some and start spreading on my skin and the serum will be gone and I can't feel it on my face. So I get more. I feel like I'll use this up so fast just because of that.

I'm getting compliment after compliment on my skin lately and this is the new product I have added to my routine! I use retin-a 3x a week, and this 2x a day. I do think it is helping my skin tolerate the retin-a better, and has evened and smoothed my skin on a different level than my prescription. I have a glow and my skin tone looks even better! People who've just learned that I'm 50 think I'm lying. "You look like you're a lot younger!" I use the original Resist Serum around my eyes.

I love this serum as much as all the other reviewers. It's so light and so good for the skin. Layers very nicely under all my other products.

I had been so sad to have to stop using the original Resist serum because it broke my face out badly. With trepidation, I tried the light version when it came out, and I am so happy with it! I mix it into my Resist Barrier Repair at night and it works like a charm!

This is what my skin has been waiting for! My breakouts have just stopped, it's healing my red spots and I have the healthy skin glow. I'm stocking up on this one! Not even the Resist AHA, or the Retinol have given me these results.

Where on earth has this particular serum been all my life. Great results just Paula's other sera but the hand feel on this one is fantastic. It is lighter than the others and goes straight into my oily, but aged, skin. PLeeeese don't stop making this, Paula. It is almost too good to be true. Lois in Galveston

I have used this serum in winter and in spring. I had hoped that in spring I would have better results, given the decreased moisture needs of my skin but it didn't do anything visibly noticeable. This serum didn't change the texture of my skin either. I had high hopes, but this serum wasn't for me.

I have VERY oily skin, and I wanted a serum to use during the day to help with the brown spots and redness in my skin. I was hesitant about using a daytime serum since they have a tendency to hang heavy on my skin, to the point where I only use them at night and don't bother with a moisturizer. But this one virtually disappears on my skin. I cleanse,use PC toner, BHA 9, this serum, and PCs Skin Balancing Defense Lotion; makeup goes on and stays on perfectly. This is a fabulous serum!

I originally purchased this serum for very mild wrinkles on my forehead and eye corners, which it seemed to help in tightening and reducing the lines. It also helped a little on the "11's" between my eyebrows but not to the extent that it helped the forehead and eye lines. I guess I need something more powerful for the "11's" (Retinol?)

I tried the Balancing and original Resist antioxidant serums in the past. I use them as eye serums and love them!! The Ultra-light serum is perfect for acne-prone skin; NO breakouts! It's very thin and absorbs instantly which can make it difficult to spread across the face, but the results are fantastic. I had perioral dermatitis around my nose and within a week, it has completely disappeared! The texture of my skin is just awesome!

I have normal skin and if I put this serum the wrinkles under my eyes become more pronounced. It just sucks out the moisture from the skin. Maybe it is good for oily skin but I doubt it. On the plus side it doesn't make me break out as the Olay seum does.

So happy I tried this! I tried some sample packs of the above product and it did BEAUTIFULLY on my combination, acne-prone skin! Now I just need to order a full tube...

My Skin is normal/oily combo, acne prone with red and darker scarring from acne marks (both recent & old). This serum is the best one for my skin type. Within 1 week of receiving & using this PC serum 2x daily, it has evened out my skin tone, reduced scarring & made my skin youthful and glowing (exactly what I want it to look like should it should be) Words alone are not enough to the results & benefits of this PC Serum. Thank you Paula & PC Team!!!!! If you have combo skin you should try this!
