Editorial Review
Zeno is a hand-held battery-operated device designed with a tip that heats to a pre-set temperature. The biocompatible tip is designed for direct contact with a blemish on the skin. Once in contact with a blemish, the tip will transfer heat into the follicle. An internal PID controller chip continually modulates the temperature to a fixed range even under different skin and circulation conditions by adjusting the flow of energy to match precisely the heat absorption of the individual user. Zeno’s microprocessor adapts not only to your individual skin type but also to the heat absorption characteristics of the location of the pimple. Your Zeno adapts to you! An integral digital timer controls the treatment time. The level of heat does not cause skin damage.

Specifically, Zeno stimulates a heat-shock response in p. acnes, the bacteria causing at least 90% of all acne blemishes. Heat shock proteins, activated by bacterial cells under heat stress, cause the self-destruction of p. acnes within the lesion, reducing inflammation and allowing the skin to return to a healthy state.
What is Zeno?
Zeno is a handheld, portable electronic medical device that is clinically proven to make pimples disappear fast. In fact, for treating acne pimples, it's the most scientifically advanced and effective device available without a prescription.
What does it do?
Zeno applies a precisely controlled heat dose directly to the pimple through a metal pad. One treatment lasts 2½ minutes. Two to three treatments spread over 24 hours clear up most pimples quickly. It's that simple.
How does it work?
Pimples occur when excess skin oil and flaking skin plug the opening of a hair follicle and create the ideal environment for acne bacteria to grow. Precisely controlled heat applied for a specific period of time causes the bacteria to self-destruct. When the bacteria die, the pimple goes away.
How many treatments does it take?
Two to three 2½-minute treatments spread over 24 hours are sufficient for most pimples. Often, only one treatment is needed.
Who should use Zeno?
Zeno is for people with mild to moderate inflammatory acne. If in doubt, ask your doctor.
When should Zeno be used?
Use Zeno at the first sign of a pimple. It works best when used on a pimple in the early stages of development. Also, the sooner pimples are cleared up, the less chance they have to leave scars.
How does Zeno compare with topical or oral treatments?
Zeno can clear up a pimple in just hours. Most other medications can take days or even weeks to work. What's more, other than slight, temporary skin redness, Zeno has none of the side effects described by most topical or oral medications.
Is Zeno safe and painless?
Patients included in our clinical trials experienced little reaction to the low-level heat. Other than some temporary skin redness following a treatment cycle, no other adverse side effects were reported. But should you experience any discomfort when using Zeno, discontinue use and consult your skin care professional.
Is Zeno all I need for acne?
Zeno does not replace good skin hygiene or a doctor's care. It is designed to treat mild to moderate inflammatory acne. Your doctor may recommend other therapies, depending on the severity of your acne. Follow your doctor's advice and use Zeno for the occasional pimple.

Tames monthly outbreaks 
2008-09-09
As a teenager, I was never really bothered by acne. Fate, however, was having the last laugh by causing me to have monthly outbreaks that seem to have gotten worse as I've gotten older. If you are a woman in your 40s, you may be experiencing the same thing.
I wash my face at least twice a day with soap and water and I use a mild astringent or clarifying lotion about once a day. My outbreaks are cyclical, very much linked to monthly hormonal changes. Because my acne has been worsening, I asked my family physician for a referral to the dermatologist - and the soonest I can get an appointment is February 2009!
Last month, I was in the skin care section of my local drugstore, looking for something more powerful than the usual benzoyl peroxide cream, when I saw the store display of the Zeno mini. Given the price tag, I decided to go home and do some research before buying, and I recommend you do the same if you are considering this product. What I read encouraged me. I chose the Zeno mini because it costs a lot less than the Zeno Pro and it takes standard AAA batteries (included) instead of relying on a non-removable internal battery that can potentially go bad. Since I was just starting to recover from two bad blemishes and noticed another big one coming in, I decided to upgrade delivery to overnight (only $3.99 with Amazon Prime).
Here's what happened:
Day 1: Big blemish starting to appear on chin. Ordered Zeno mini for overnight delivery.
Day 2: The Zeno arrived by 9 am! I quickly inserted the included batteries and turned it on. It takes about 2 minutes to warm up. Read the instruction booklet. It advises you to wipe the metal tip of the Zeno with rubbing alcohol before every use. (Remember you are trying to kill bacteria, not spread it around with a dirty tip!) Once the Zeno was ready, it beeped and I applied it to the blemish. It beeps every 30 seconds during treatment to let you know it's working. Treatment lasts for 2.5 minutes. When I was done with the newest blemish, I cleaned the Zeno tip and used it on the two blemishes that were slowly improving, but still far from gone. The newest blemish flattened almost immediately.
Note: you can only use the Zeno for up to three back-to-back treatments at a time, then you have to give it a break.
I repeated the Zeno applications two more times on each of the three blemishes on Day 2. The heat causes a little localized redness. My complexion is very light and very sensitive, but the slight redness did not last long - perhaps 30 minutes.
Day 3: Two old blemishes are looking much improved - better in 24 hours than in over a week of benzoyl peroxide applications. After three treatments, newest blemish was almost gone. The old blemishes looked and felt much better. However, my work was not done, as a new blemish was coming in on my forehead. It was big, red and painful - and all it needed was ONE ZAP from the Zeno to put it completely to rest.
A month has gone by, and I have not had to use the Zeno in weeks. Usually, I would be getting a new blemish of the month by now - they tend to come back in the same places from month to month. Not this month! I did get one or two small whiteheads (gone quickly), and nothing in the usual trouble spots. This has been my best month in quite a long time. I can only conclude that this is because the Zeno dispatched the acne causing bacteria that had previously gain ground in those spots. The Zeno cost less than a visit to the dermatologist - and I didn't have to wait six months.
Please note that the Zeno does not dry your skin out. Benzoyl peroxide dries your skin out, and makes it red and flakey while you are getting over a pimple. Zeno heats your skin and underlying tissue sufficient to kill the p. acnes bacteria. Before Zeno, I used to try using a super-hot wet washcloth on my blemishes, but the cloth did not stay hot long enough and I was not able to really focus it on the specific areas that needed attention.
I am completely pleased with the Zeno Mini and the results it produced for me.
Sleek, Fast, and Effective ... (I Could Not Ask for More!) 2008-09-08
I'm a thirty-something professional woman who occasionally (maybe once or twice a month) must contend with a blemish. So, take this demographic into account while reading.
Though the price-tag on the Zeno seems daunting, rest-assured, the product works!! In our instant-gratification society, this little wonder fits-in nicely. Blemishes subside rapidly and with no discomfort. (The tip of the Zeno becomes very warm but the sensation, for me, was not unpleasant). After two treatments (several hours apart), my blemish was virtually unnoticeable with the help of my mineral-foundation.
Now, it may interest you to know that I've used Renova for over six-years, so I was a little hesitant to use the Zeno (though I saw no contraindications in the booklet). (For those who are unacquainted with the product, it is a Vitamin-A derivative which must be prescribed by a physician or dermatologist ... while it encourages collagen growth, reduces fine-lines, and exfoliates, it also leaves your skin vulnerable to sunlight and various other elements.) I have used this product on two different occasions with no side-effects. (I am only speaking for myself, of course. So, be sure to take care if you are in a similar situation ... and if you have an adverse reaction, feel free to comment on this post so others can read it).
The Zeno is now a permanent part of my beauty "arsenal." Between the Renova, Bare Escentuals (as recommended by my dermatologist), and the Zeno, my skin is absolutely pristine and glowing. A minor miracle ... and, as one reviewer stated and I firmly agree, I wish this was available when I was a teenager!
Bottom-line: the Zeno is quick (two and half minutes per treatment), painless (for me), concentrated (it addresses just the area that requires healing), and really cute!! (Aesthetically speaking, it is super slick!!) In my opinion (and I am a tough critic!) the Zeno is entirely worth the investment!
Nice Surprise worked for me! 
2008-09-04
I was very skeptical of this.I mean a device that is supposed to get rid of pimples? I have used this for almost a month on the occasional break out and it really does cut the healing time down to half.Where it usually takes a week for my pimples to vanish,it took 3 days with the zeno.
Basically you place the head on your blemish, the zeno heats up,supposedly customizes to each persons body temp.,You leave it there for several minutes and that's it! It does feel warm but by no means is painful.
The head does need to be cleaned and replaced occasionaly but for what it does the process and upkeep is minute.I highly reccomend the zeno and am very glad I found it!
Used Properly, Works like it claims 2008-09-02
For reasons unknown, I recently experienced a "pimple crisis". Chalk it up to middle age hormones I guess. I was experiencing those deep pimples that REALLY hurt, and usually in the same spots. Enter Zeno. I had read about it in several magazines, but did it really work like it claimed? Well, for me it worked wonderfully. Continue your everyday skin washing still (that's pretty much common sense for most of us), but most importantly make sure you read the directions before using it. It says to use it on a pimple when it first forms, so if you wait more than a day or so, Zeno is not as effective. Once the pimple has blossomed or matured, the damage to your skin is already done...this means that if the pimple is already red and/or inflamed, then you probably "missed the boat" with Zeno so to speak. Whatever you do though, do not pick. My experience, as long as I followed the directions on new pimples, was very positive. I did try it once on an older pimple behind my ear and it did shorten its "stay", but it was nothing compared to the 12-24 hour turnaround I was getting on new pimples.
The very first medium sized pimple I used Zeno on only took one treatment and was no longer visibly noticeable the following day. My second pimple, a bigger deeper pimple that hurt to touch, took three treatments. But, the most amazing thing about the second pimple was that the swelling minimized almost right away for me and it also was no longer visibly noticeable the second day (this was really incredible to me, because a pimple this size would normally leave a small scar on my face, but that never thankfully happened). I will continue using Zeno because this is a HUGE plus for me (no scarring). If you get those type of pimples, you know what I'm talking about!
Anyways, Zeno is basically an uninterrupted 2 1/2 minute treatment that uses heat. It feels warm, but it does not hurt at all and it does not burn skin. I personally did not experience any "temporary redness" that it mentions in the manual, but I did read somewhere that Zeno is about 118 degrees Fahrenheit, so do expect that this can happen. In my earlier years, I used to use the "hot washcloth" technique like others. I really think it is neat that a company has finally harnessed this idea more efficiently and effectively than an unstable hot washcloth! However, I definitely would not recommend to use Zeno with any other acne products though, especially with ones (or even medicines) that can cause skin sensitivity. I also would not recommend Zeno if you have severe acne, the kind that is all over or blackheads (they actually say this in the manual).
Overall, my experiences have been very convincing that Zeno does indeed get the job done, thus living up to its claims. I will continue to use Zeno when I experience a "pimple crisis". It also says in the manual that the heat of this product kills the bacteria that is the cause of most pimples (called "p.acnes"). So, it is definitely worth giving it a try before you go to a doctor or put some chemical on your entire face for one small outbreak.
WoW It Really Works...!!! 2008-09-02

It's a lifesaver! 2008-08-26
I've had this product for about 2 months now and it works great! I get breakouts about 2-5 times a week and its helped me out a lot. I noticed that it works best when i can notice that there is a small red bump under the skin or if it hurts a little bit. the heat does provide some relief initially. use it once in the morning and once in the afternoon when i have a pimple. i noticed i changed the batteries out with about 25 uses which is about a month for me. i wanted to write a review because i wish someone told me about this product sooner!! thanks
Love it!! 2008-08-25
I just got the new zeno mini and I love it!! A friend of mine has the bigger one and she let me use it and I was hooked. When the mini came out, it was just the right price for my budget. This product is great for my monthly break-outs. My friend is so happy I won't be stealing hers anymore. I like to use my zeno in the evening prior to going to bed. It's a short 2.5 minute treatment. Not getting the zit is definetely worth it. I had a "big" one I could feel under the skin and it never surfaced!!! I did two 2.5 treatments and then another the next morning. Thank you Zeno!!!
Great for acne flare ups 2008-08-24
My husband has occasional acne flare ups. He always travels with this so he will stop any out breaks before they become pronounced. We highly recommend the Zeno Mini because of its effectiveness & ease of use.
Just as effective as the original 2008-08-22
I have the original zeno and this one. (I keep the mini with me when I travel.) They both work extremely well! I have used many other devices and have yet to find anything as effective. My son is beginning to need to use it too and it works on his acne. I recommend this product to all my peers and my son is beginning to tell his friends about it! Thank you for making such a good product!
