Silk’n SensEpil vs. no!no! Hair Removal Devices

This entry will compare the Silk’n SenseEpil with the no!no! hair removal system. By the end of the article, those attempting to discern the differences between these two devices should be able to do so very comfortably.

The first way these two devices are alike is through the basic hair removal mechanism. The Silk’n SensEpil uses optical light technology to gently heat the root of the hair, disabling its growth. The mechanism is the same with the no no device. The no!no! uses heat that results in a long term reduction in the hair’s regrowth. With either device, users are left with skin with hair that grows in finer and less dense than before.

Multiple Uses Required

Like many at-home laser hair removal systems, the SensEpil and the no!no! require several uses to achieve the best results possible. With the SensEpil, users should perform hair removal sessions once every two weeks, for about ten sessions total. Users of the no!no! hair remover will see their best results when the device is used twice a week for about six weeks. Both of these methods require multiple uses due to the way in which body hair grows. The SensEpil and the no!no! each target hairs that are in their growing phase, which is not constantly occurring.

Treating the Skin

The preparatory work for treating with the Silk’n SensEpil and the no!no! is similar as well. For the best results, both devices require the user’s hair to be stubble length at the longest. Additionally, users should have their skin clean, and free of lotions and other cosmetic products as well.

Side Effects

The side effects of using the SensEpil are the same as using the no!no! hair removal device. When used properly, neither device should cause any adverse side effects. Typically, the most common side effects include a slight redness on the skin over the area that was treated. These painless devices may also cause the user to experience a slight warming sensation across the skin that is being treated, as well.

What is Different?


The first of several differences between the SensEpil and the no no is the devices’ sizes. While the Silk’n SensEpil uses a wand for hair removal, it is attached to a larger base. On the other hand, the no!no! is much smaller, and can be convenient for reaching tight areas. Because of its decreased size, however, it does a smaller treatment area. The larger treatment area of the SensEpil device allows users to treat a large area of their body, in a small amount of time.


The SensEpil device must be plugged in in order for the device to be powered on. This is not the case with the no!no! device. After an initial five hour (or overnight) charging period, the no!no! runs on a rechargeable battery, and is completely cordless. If users choose to do so, however, it may also run while it is plugged in (although not during its initial charge).

Replacement Parts and Accessories

The Silk’n SensEpil utilizes replaceable cartridges that deliver the optical light energy to the hair’s root. These cartridges are designed to deliver about 750 pulses. This is enough pulses to allow users to treat their entire body completely, or a smaller portion of their body several times. The no!no! also features parts that need occasional replacing. Rather than cartridges or lamps, however, the no!no! uses replaceable Thermicon tips that last between 2 and 3 hours of use. The SensEpil’s replacement cartridges are sold for about $38 each, while replacement Thermicon tips for the no!no! are sold for between $25 and $29, for narrow and wide tips, respectively.

Who Can Use It?

The SensEpil device, because of its mechanism, is safe to use for a limited number of skin tones and hair colors. The best results from the SenseEpil occur with those with fair skin, and dark hair color. The no!no!, however, is safe to use on any skin tone. It can even be used safely by African Americans.

While the treatment area of the no!no! is much smaller than the SensEpil’s, the no!no! is approved to be used on the face (with caution). This can make it an excellent device for removing unwanted hair on the upper lip, and in the sideburn area.

Method of Use

While the end product of the SensEpil and the no!no! is the same (a reduction in hair), the way this is achieved is different. With the SensEpil, users hold the device is place while a pulse of high-powered optical light is directed to the root of the user’s hair. After a pulse of light has been emitted, the wand is moved to a different part of the skin being treated, and the process is repeated. With the no!no!, users slide the handheld device slowly across his or her skin, perpendicularly to the skin. After each hair removal session with the no!no!, users should exfoliate the skin with the included buffer pads to remove any residual hair. Note: As the hair is crystallized with the no!no! device, users may notice a slight odor, which should fade.

Final Results

The final results of the SensEpil and the no!no! hair removal device vary slightly, as well. After several uses, the SensEpil delivers hair removal that is essentially permanent. After just a few months of treatments, users should have little to no additional hair growth on the areas that were treated, and hair removal sessions on these areas should be rare, and performed only as needed. The no!no! does not deliver the same permanent hair removal results as the Silk’n SensEpil.


Both devices remove hair in a similar method, and require several treatments to reach their maximum results. They leave users with thinner, finer hair after just a few treatments, with no nicks, cuts, pulling, plucking, or any harsh chemicals or waxes. The SensEpil uses a larger treatment area, allowing users to treat more of their body in less time, while the no!no! uses a handheld design that can easily maneuver where it is needed. Additionally, while the no!no! is slightly less expensive than the SensEpil, its repetitive use can be timely, and the continued replacement of the Thermicon tips could prove to be costly over an extended period.
