I love this product as a morning treatment. It gives skin great texture, makes it mat, and also gives a really fresh look to my face. I believe it does what it promises - makes you look like you have a healthy lifestyle. It lightens my skin a little too.

Background on my skin: enlarges pores, combo-dehydrated with acne below the cheek, chin and upper lip area. Prior to NB products, I've used BP 5% and Olay's Active Hydrating Beauty Fluid for Sensitive Skin. Worked out not too bad, but needed more improvement.
I chanced on this one little boutique that was selling some T. LeClerc makeup, and the SA loaded me with some samples of NB. She recommended that I use this serum and diamond gel-cream in the day. She also recommended using The Cure Pure Serum and O2 cream at night. Now I understand why...
I'm using this serum along with the O2 cream at night as the cream is pretty heavy. I also have been using Glyco Peel Plus (now discontinued). The serum is great, especially when applied after using the glyolic peel. I've only been using it for about a week and I've seen such beautiful results. The serum is somewhat light and absorbs easily. at Night I also stopped using BP. I asked the SA at the Neiman Marcus counters if using BP along with O2 products is safe, she said that it would be ok as O2 products are not photosensitive and would not recommend using Retinol with O2 products (unless told my the dermies). Overall, O2 products have transformed my skin. Although its only been a week and a few days, everytime I would use the Glyco Peel my skin would purge. But lately I've been healing a lot quicker. I cannot wait to see the end results afte 12 weeks of glycolic peel :)

Let me start by saying that I have been using the Natura Bisse Glyco Line Extreme Peel for over 6 weeks and did see some good results. My skin felt smoother and the pores slightly smaller. I will soon try the La Prairie Cellular 3 minute peel for comparison.
I had also started using the La Prairie Resurfacing Cream recently which did help with pore size as well. I added the Oxygen Complex to the regimen and saw great results. I also use the Oxygen Cream during the day which was perfect for the winter weather. I was using the Biologique Recherche Creme Vip O2, but the Natura Bisse Oxygen Cream was richer which I needed at the time.
I am very happy with the Oxygen Complex and Cream which I believe has helped to shrink my pores and even out my skin tone.
Also, I applied this product directly during a break out and it helped to resolve it quicker.

This is a dual review for the NB Glyco Extreme Peel and the NB Oxygen Complex Cream.
These two products have been life changing for me! i know that sounds drastic, but the reality is, my results were drastic. I don't even remember how i randomly came across the reviews in pville, but i'm sure glad i did. i was overwhelmed by the amount of good reviews on these two and i was extremely curious, though i was a bit turned off by the price. so, i did what i always do when something seems a bit steep and i'm not sure it will give me the results that it claims to -- i went to Ebay! on ebay i found numerous listings for both of these in lots of sample packs. i ordered enough of the O2 complex. cream and the Glyco Extreme Peel to last me for 6 weeks, which i felt was an adequate amount of time to decide how i felt about the product. Around the same time i also started using the OCM (i swear by that as well), and i think the combo of the cleansing, treatment and peel is definintely to thank for my results.
When i ordered these I was having terrible terrible hormonal breakouts on the daily....deep cystic hormonal zits that would hurt like hell, refuse to go away, and refuse to be hidden or camoflauged no matter what i tried. i had great skin all my life so this was a real shot to my ego and self esteem so after a few months of dealing with this, i was really distraught. the OCM, NB O2 Complex, and NB Glyco Extreme Peel changed this completely and then some!
Almost immediately (easily within the first week), the hormonal acne stopped...completely stopped. The next thing i noticed was how great my skin looked -- the tone, the radience, vibrancy, firmness -- all of it improved beyond my wildest dreams. Shortly thereafter i noticed that my old acne scars were fading and disappearing as well!! These products were a God sent!! Prior to using this combo of products, i would read other reviews on products where people would swear a serum or treatment or mask was HG, that it changed their life, that b/c of this product they didn't even have to wear foundation anymore....and when i read these reviews, i thought "bull sh*t" because even imaging my skin on its best day still required foundation. not anymore. i'm one of those people now that i thought were full of sh*t. i have never in my life (not even as a teenager) seen my skin as beautiful as it is now. i still get the occasional small zit here and there but they go away a lot quicker, scar far less often and hurt a whole lot less than before.
I will never be without these products again. Ever. Period. I strongly urge anyone who is looking for some products to transform their skin to look into these!!! Do as i did, and test it out w/ some samples on ebay and decide from there. Soooo worth it!!
For reference, i use the O2 Complex Cream in the am and pm, directly following the OCM. i take a very small amount (you really do not need a lot -- i can make a single sample packet last through 4-6 uses) and massage it into my skin until i can feel it being absorbed and sink in. This isn't greasy or anything like that. it's lightly moisturizing but i still use another moisturizer w/ spf. the Glyco Extreme Peel i use exactly as directed...2x a week (for the 1st 6 weeks)..i'm on week 5 now i believe and after i finish up my 6 weeks i will reduce it to 1x a week for upkeep. i simply rub a small amount around my face, concentrating on my big problem areas (again, you only need a little bit - i can make sample pack of this last 2-3 uses as well). on occasion, when i have an open zit (yes, from picking) it will burn for a split second but then it immediately goes away -- it doesn't burn at all like other products i've used. then i rinse it off with a warm washcloth and follow w/ the O2 Complex Cream. Very simple...not time consuming...and as i've said, the results are beyond amazing. i love this stuff!!! <3

I have already finished 2 bottles of the Oxygen Complex. Oxygen Complex really does restore the skin's vitality. It brightened my skin and even my friends noticed it. I however want to try something new. If nothing works out for me, I will buy it again.

I really wanted to like this product as I had excellent results with Karin Herzog's Vita-A-Combi 2 Cream (2% oxygen), $52 for 2 oz but Karin's cream felt heavy to me. I loved the texture and the pump of Natura's serum however it didn't do much for my skin. My facialist (who used to assist plastic surgeons and is well versed with lasers) agreed that it was "ok" but not great. I have purchased Natura Bisse's Glyco Extreme Peel and I tried this serum after. I love the peel (my skin has never looked better) but frankly I prefer NB's Oxygen Cream (not serum).

Jan Herzog's above cream is a little heavy but in the morning my skin always looked amazing. The most important feedback I had was from 2 friends who only use the best products and are very rare to hand out compliments. One friend commented that my skin looked amazing and then the next morning (in the blaring sunlight), she said, "Jesus, your skin looks translucent!" I only wish I could have those compliments from Natura's Oxygen serum, esp. at $132 for 1 oz (sigh).
***Update Oct. 2010 - I went without this and I noticed a difference in that my skin didn't look as good after my Peel. I bought this again and I'm pleased with the results (after my Peel, I use the serum, then top it with the Oxygen Cream).

I am Korean, 42 yrs old but most think I'm 28-32. People say my skin is like porcelain but it has good and bad days like everyone else and I have combination skin (however prone to plugged pores and occasional breakouts).

After buying La mer creme I was over buying pricey face products. I suffer from hyperpigmentation and breakouts after my menstrual cycle. Tha SA at Neiman told me to give this product line a chance. I took the samples home . I cannot even begin to tell you how improved my skin is. My boyfriend actually told me this is the best my skin has ever looked. I saw a difference in 6 days. On Saturday I went and bought the bottle. It is expensive but It is worth it. I also picked up a sample of the glyco peel since everyone on this site gave wonderful reviews. I CANT WAIT TO SEE WHAT WHAT IT DOES!!

Unfortunately this product simply did not work on my skin. I badly wanted it to, but the purging never ended. I always had a new breakout the following morning after using it the night before, and they were always the congested type way underneath the skin- not cysts that signify hormonal- but small deep whiteheads that are impossible to get rid of. I finally had to return it.

I've been using this in conjunction with the Glyco Peeling 50%, except I put this pn every night before bed, not just after the Glyco treatment. This serum is nothing short of AMAZING. Before I was very oily with lots of blackheads and some zits I've been using some great skincare products, and no - they are NOT cheap - but this serum makes sure that I wake up to beautiful, bright and non-oily skin. In fact, it helps to transform my skin. My pores seem smaller, my skin is smoother, and I swear it even seems to glow in the morning! During the day I use a different serum (Skyn Iceland Bio-Intense Healing Serum), as this one has hydrogen peroxide to some degree and can tint your eyebrows if you go out into the sun with it on. I don't want to take that chance, so I just wear it at night.

It delivers results which it promoises - clear, brighten, regulate, hydrate. I think Natura Bisse is even more effective than Sisley and La Prairie. I will definitely repurchase. The only thing is it may not be moisturizing enough for winter nights. Otherwise, it's perfect.

i love this product but i think the key to it may be to use it the way the salesperson at barney's told me to. she told me this serum is most effective after using the glyco peel . i purchased the 50% glyco peel (after trying samples of the 25%) and use it twice a week at night. after washing off the glyco peel (with a sponge) i apply the oxygen complex and am AMAZED by the results the morning after. i havent used it any other way ... and generally i dont fall for the hype/ push to by multiple products to use together but the salesperson was so great and so confident in the product that she gave me two weeks worth of samples and said come back if you love it. i would recommend requesting samples first or purchase from a store that has a good return policy (as barneys does).
this product works wonders for my skin. it was very congested with breakouts and leftovers from previous ones and this routine is bringing it all out and smoothing out the surface... im thoroughly impressed and ive only been doing it for a couple of weeks. the oxygen cream is also great!

I wanted so badly to like this product, but it did nothing for me.

Very expensive, but, it does indeed do the job it sets out for. I had stupidly purchased a giant size bottle of Olay Total Effects at Costco and had a major breakout on both my face and chest ensue. For weeks I had darkness and marks leftover from the explosion and yet after 5 days of using the Oxygen Complex I noticed a 50% improvement. My chest now has more of a "freckle" look and only one out of every five marks on the face looks noticable. I'm very pleased with this stuff and hopefully it will continue to be a winner for me.

At first, I was sort of sceptical that this product would make any sort of difference on my skin, but it has made a dramatic improvement in my skin. I can't even stress the difference. It has definitely clarified my skin and made it look a lot brighter. The dullness has disappeared and although there was a slight breakout that happened when I first started using it but the SA told me that it would happen as my skin tried to clarify itself. Once it went through that cycle, I haven't had problems with breakouts at all.

This is not inexpensive at $120.00 for 1 oz but this is the ultimate night serum for my acne prone almost 34 year old skin. I use PC 1% in the a.m. and this in the pm and it clears my skin and hydrates at the same time while keeping my skin looking smooth and vibrant.
