Can't do without!

I love what this serum does. It keeps any adult breakouts under control and also reduces fine lines....really! I have been using this nightly for a few years and I make sure to always have it on hand. A third dropper full is more than enough for entire face. I highly recommend it.

I have been using this serum for a few years now. I was introduced to it during a facial at a spa. I love how it evens out my skin tone and prevents any adult acne breakouts. I make sure I always have this on hand.
Love it! A little goes a long way!
LOVE this product

This is an amazing serum and the only thing I have found that really controls my acne and the appearance of pores. LOVE it!

Seriously…it is. I hope that I'm not jinxing it by writing this review. One of my doctor friends had me try it before I bought it here bc let's face it: my bathroom cupboards are product graveyards. But this actually works! I use it at night after washing while face is very slightly still damp. It takes care of discolorations, fades acne scars and does NOT break me out.

This serum is a great exfoliator.
The best stuff

My son uses this in combination with the Glymed 1 kit and it works miracles. My son is an actor and has heavy makeup used during filming and he always breaks out from it. This along with Glymed has been the only thing that has every worked and we have tried everything. We go to a very popular facialist that works on celebrities and this is one thing that she is using on tons of her clients (I know several). Now you know the Hollywood secret.

This serum is amazing! It provides a good level of exfoliation but also makes the skin feel tingly! It's worth the money!

I was introduced to this product by my dermatologist - when I went in with severe skin sensitivity, breakouts, redness, irritation and general inflammation. I didn't know what was causing all my skin problems and asked for her help. She recommended that I stop using all products, including my clarisonic brush - and only use Eucerin redness wash, IS Clinical Youth Complex morning and night to moisturize, and then IS Clinical Advance serum in the morning, and the Active Serum at night. It took about 2 weeks but my skin completely cleared up!!! The redness was gone, the acne was clear and my face looked amazing! I continued to use all 3 products until gone and now my skin looks better than ever! The Youth complex glides on like silk. My skin looks brighter, and more hydrated, smoother and younger. I don't know which product in the IS Clinical line to credit to my miraculous improvement - but I am a forever believer and consumer from now on! I am in my late 40's and I feel like I am turning back the clock every day I begin using it. Highly recommend for anyone - but especially sensitive, acne prone, oily but still aging skin!!!
This Stuff WORKS

I LOVE this serum. Received a .5oz bottle as a gift, and it sat in my closet for 6 months. One night I decided it was time to pamper and facial, so I took it out to try after a good deep cleanse. The next morning I truly looked 5 years younger. My face was glowing, my pores were amazing, and the very fine wrinkles were less. My skin looked overall much brighter! (I am 42). I used the IS Clinical serum every night for the next two weeks, and all of my results continued and my skin looked so great that EVERYONE began to comment on how young I looked, from my kids' teachers, to my hairdresser, to my best friends. This stuff is expensive, so now I am down to using it a few nights each week (2-3), but my skin looks great, about the same as when I was 30, but even better, because as a surprise bonus- no more breakouts! This serum also zaps acne. I started using it on my 15 year old son 2 nights a week, and his face looks 75% better after only two weeks. I am now buying this product in the 1 oz size as I need it, I WILL NOT be without.
Safe for pregnancy

When I was pregnant I couldn't avail of my usual facial products and treatments (salicylic acid and skin peels), so my aesthetician recommended this product. It helped improve skin discoloration and texture, without having to get facials. It's very pricey but you only need a small amount for each use.

After having suffered from adult acne for over a year, this is the only product that has produced positive results for me. I have spent so much money on prescription creams and pills and can't believe all it took was this serum. Great product- wish I would have tried it sooner.
My miracle product!

I've used this product for a little over a year. Along with hydra-cool and super advance , takes a good 3 months to see what this product is made of(as do all skincare lines)and it's wonderful! Blemishes disappear over night. Skin is a confidence one can't live without. Oh and be sure to screw the cap on I dumped mine all over my bathroom floor today Ahhh!

I have the occasional pimple here and there... I consider my main problem as filled pores. I have found this product to work better than any other product I've tried. And I consider myself a product junky. Always researching the latest active ingredient and trying different products. I will look no further and will never go without my active serum. My skin looks the best it has in years. Worth every single penny.

I love this serum. It's wonderful and keeps your skin exfoliating everyday. When you cleanse at night, you feel like you are getting a fresh derma and it keeps your skin dewy and radiant looking. I keep this in stock so I don't run out!

I find this prodouct to be highly effective! It works great at keeping skin bright, even and glowing! I just wonder if anyone has compared its effectiveness with Nucelle Mandelic serum.... It too is a wonderful product in much the same way!

This is the best product I have ever used. I use it in the morning and it makes me feel more awake a refreshed. I have not had a break out since I have started using it and the dark spots on my face have faded. Worth every penny!

I have an acne-prone oily skin. I have used these kinds of serums for years and this serum is one of the best. It works good at my acne and its after. I used one whole bottle for 4 months. I recommned it to friends. No acne brought from this product. That is a big PLUS.

This product is worth every penny. You will see results immediately. Skin firming and acne preventing across the board.

Tingly and fabulous!

This stuff is liquid gold, ladies (and gentlemen). My face was not a happy camper prior to this serum: really large pores, a few blackheads, acne flare-ups, rosacea, fine lines. After three weeks of nightly use, my pores appear 75% smaller, fine lines are fading and all the other problems are simply gone. I have not experienced any redness or irritation from this product. My evening regimen: iS Cleansing Complex, this iS Active Serum and the iS Firming Complex (just started the latter). Sometimes I'll finish it all off with Kinerase Night Repair for a little peptide zip, but ultimately the serum does the heavy lifting; I used it alone for long enough to tell. No buyer's remorse whatsoever--will always have this handy!

I am asian . I had oily skin but not now. This product is great! I am happy finally my skin is smooth.
One of My Favorites!

I LOVE the Active Serum. It helps with everything. My acne goes away in one night and there are no scars or redness left behind! You can really feel it working when you put it on. I spread some drops over my face at night, spot treat in the morning, and use sunscreen and my skin has never looked better. It is seriously one of my favorites.

For years I was a sunaholic, now into my mid 30's I have become the exact opposite. I researched many different companies for products that would 'lighten' and correct some minor hyperpigmentation and freckles but without the use of hydroquinone or other harmful chemicals. So I took the chance. After many product trys and changes, throwing half of them out, spending major $$$$ I figured whats one more useless product! After one week of use my esthetician even noticed that my skin looked 'the best shes ever seen' I am able to wear no foundation (which was one of my goals)instead I just use a mineral powder and a bronzer and im ready to go. I have oily/sensative skin and although PRICEY, def worth it!!!

this product is so far the best serum I have ever used. It's perfect for oily skin and it helps with my acne and scars. Love it!

After reading great reviews of this stuff, I decided to take the plunge and empty my wallet. Believe it or not, it was totally worth it! In just two days, I noticed significant improvement. Pores are smaller, skin is MUCH smoother.
most amazing thing in the world

i have really bad acne and i started using the active serum and with in a few days my face was looking better then ever all my acne had cleared up and it didnt totally dry me out. i totally recommend this product i think everyone should own this it is worth the price no question in that.

Let me begin by saying I have tried EVERYTHING out there. Obagi, laser treatments, dermabrasion, etc. etc. I am 41 years old with combination skin that breaks out easily. I have been using the active serum at night for 3 nights and the healing serum in the a.m. for 3 days. My face is almost completely clear. I have no dryness at all and I get excited to wake up in the morning to see what my skin looks like for the day. My 17 year old daughter used it 2 nights and I kid you not her face cleared up at least 40%. I can't wait to try more of their products. I don't care what the price is since the results are amazing!!! For the first time in 15 years I feel excited about something that works to clear up the acne without making my skin red and dry. If you were frustrated like me, give it a try....I hope you have the same great results I am after only 3 days.

I have only been using this for 10 days, but the reults so far are amazing. My 35-year-old combo, oily, acne prone skin had been looking terrible...I had been noticing uneven teture, large pores, and practically overnight, lots of fine lines. I also have been getting breakouts, both tiny, under-the-skin bumps, and larger, cystic-style pimples. After two days, the existing pimples were gone, after five, the red spots left behind from mulitple pimples were gone, and today my skin was so clear and glowing I only wore tinted moisturizer and NO concealor. There is also a significant improvement in the fine lines. I have been using this at night, waiting 20 minutes, then applying Neutrogena oil-free moisturizer over it. I am still applying Estee lauder Advanced Night repair in the am under my sunscreeen. I am thrilled with this product, and will be trying more of iS Clinical's products. This has been worth every penny.

This is the only glycolic product that my sensitive skin has ever been able to tolerate. I was hesitant to try it, only because other glycolic products have caused my skin to be reddened and rashy. But I love the iS Clinical line so much, I decided to give it a go. I figured if my face could not tolerate it, I'd use it on my hands. Well, my face loves it! This is now the only night treatment I use. It will sting a tad when first going on - but eventually, that stops, and there is just a cooling sensation from the menthol. I will always use this product! In the morning, I use the Vit. C&E, along with the Youth Complex in targeted areas (a miracle product!) and the HydraCool. That's all my skin needs. I used to have dry skin, but these products seem to have equalized and balanced it. I am 58, but most people are startled by that - and think I'm more like 43 - 45! I think iS is a great line of products.

I have been using this serum for a few months now and can tell a HUGE difference in the overall 'glow' of my skin. I am getting complements daily almost. I have used Arbonne too and just ahve to say it was awful -felt heavy-and expensive for an over the counter type product. Also don't like their pyramind marketing thing. I stick w/ what my Derm & Esthetician pass on.
Posted 2/9/2008 by Anonymous
DID NOT WORK AS WELL AS THE ARBONNE ACNE PRODUCTS i WAS USING. ARBONNE IS LESS EXPENSIVE AND BETTER.
