Chances are that you’ve walked past someone and admired their skin before now. You can’t just get over the smoothness and the cleanliness of their skin and you wonder what you are doing wrong.

Well, it is okay to admire clean and smooth skin (besides, we’ve at some point done the same) but do you know you can have the same effect that would leave people in awe of your skin too?

It’s time to say goodbye to dry, flaky, wrinkled facial skin!

You would agree with us that the cleaner your skin is, the better it makes you feel. Cleanliness, in this case, means that the appearance, texture, and health of your skin are not compromised in any way.

The facial skin is super sensitive and as such calls for careful maintenance. You want to be sure you are taking the right steps in cleaning your facial skin. To tend to this, there are several off-the-shelf facial cleansers, depending on your skin type. However, one common mistake we make is that we place lots of focus on the makeup removal cleansers and little to no attention on the tools for cleaning.

Just as there are different cleansers and brand manufacturers, there are many facial cleaning tools too. One of which is the hi-tech Foreo Luna facial cleansing brush.

In a previous post, we did an extensive comparative analysis of the Foreo Luna Mini 2 vs 3. If you haven’t read that, you can check it out here . However, in this article, we would focus mainly on comparing the Foreo Luna 3 vs Luna 4.

Grab some pie as we coast off!

If you are new to the brand Foreo Luna, maybe the right place to begin would be a little background story to get you familiar with them. However, if you’ve heard about them, you could just skip the few introductory lines and head right to the next section that bears the header “Foreo Luna 3 vs. Luna 4”.

Foreo Luna is a Swedish beauty tech brand owned by a Bosnian-born Swedish investor Filip Sedic. Their product line is all-encompassing as it offers cosmetics and beauty products ranging from facial cleansing brushes to microcurrent technological devices. The Luna device is their pioneer skincare gadget dedicated solely to exfoliating and anti-aging facial massagers. The device employs its patented T-Sonic technology, which pulses 8,000 times during each use, helping to remove up to 99 percent of makeup and exfoliating dead skin.

With this little background story, we can now proceed with comparing both types of Luna products.

Similarities: Foreo Luna 3 vs. Luna 4

  • 2-in-1 deep cleansing and setting silicone brush
  • Both devices are clinically proven to eliminate about 99.5% of dirt, oil, and makeup dregs.
  • Both devices are anti-bacterial and hygienic to use.
  • Both devices are made of soft silicone that glides gently over the skin to exfoliate toxins that are deeply entrapped in pores, lowering the likelihood of a breakout.
  • Both devices use a T-Sonic pulsation that serves as a firming massage device to help increase microcirculation that drives the active ingredients from your skincare products deep into your skin for effective results.

Unique Features: Luna 3 vs. Luna 4

Luna 3

luna 3

The Luna 3 is a dual-purpose cleansing and firming device designed to suit the different categories of skin types. It has been clinically certified to cleanse the skin of oil and dirt residues from the skin. According to Foreo, Luna 3 is made 35x more hygienic silicone than nylon brushes, which is incredibly soft and bacteria-resistant — the gentlest and most sterile facial washing tool ever created. Dead skin cells are exfoliated softly and without abrasion using interfaces made of ultra-soft silicone. In addition, its low-frequency pulses ease the appearance of tiny wrinkles and tension points in the facial muscles for a firmer complexion.

The Technology behind:

The Luna 3 uses the T-Sonic technology, which pulses 8,000 times during each use, to help remove up to 99 percent of makeup debris.

Luna 4

Design

luna 4

The Luna 4 is a two-faced device that allows you to use a brush for face cleansing on one of its sides, and on the other, you could use the pulse, firming massager. Isn’t that cool? oh, you could say that again.

Now think about a company that pays special attention to details and there is Foreo. As a confirmation, you would observe that the silicone bristles present on one side of the brush are easy to clean and has anti-bacterial protection. To cap it all, the Luna 4 device is gentle on the skin.

On the other side of the brush which has the massager, it is powered by a technology that simulates Gua sha . It has a very soft silicone with an elevated rippled texture to aid massaging. The vibrations are of a lower frequency and would do a perfect job of lifting and toning your skin.

The oblong-shaped Luna 4 device is designed in a way to help de-puff eyebags and also to carve your cheekbones. For effective use, Foreo advises the initial application of a serum to allow for easy gliding over the skin without any form of discomfort.

The technology behind

Asides from the aesthetics of the Luna 4 device, the technology behind the device is amazing and thoughtful. Luna 4 makes usage very easy as it gave the option to enable users (especially, first-timers and newbies) to customize the device to their preference. For instance, the brush head allows you different customizable options such as making a pick between dry or oily skin or even a combination of both skins). Also, you could make a selection from the three options (regular, gentle, or deep cleanse) available on the device modes.

Texture

Whilst the silicone bristle on the Luna 3 feels soft and silk, the bristle on the Luna 4 is softer and silkier. You could think of them like a very soft brush rather than a silicone pad. And just if you’ve been a little unsure about buying the Luna 4, you could give it a try now that the Luna 4 is available in a softer variation.

The Luna 4 has been clinically proven to have microcurrent and LED light therapy targeted at reversing skin aging signs including pigmentation and dullness. While the microcurrent helps to keep the skin firm and plump thereby reducing the visibility of wrinkles, the near-infrared LED light boosts collagen and elastin production, which restores the thickness and flexibility of young skin. It also helps reverse indications of skin ageing including pigmentation and dullness. However, the Luna 3 is limited in its features.

Also, with the Luna 4, you get an additional customization option to help tailor the device to your specific cleansing needs.

The T-sonic pulsations of the Luna 4 helps to promote the outflow of the fluid thus increasing radiance for a bright and smooth skin.

In terms of color variation, the Luna 3 comes in three distinct colors based on the different skin types while the Luna 4 allows you to customize the cleanser according to your skin type.

luna 3 vs. 4

Functions

The Luna 3 would do a perfect job of cleansing than other models released before it. It lasts longer and the brushes feel softer and give you more operating options than its predecessors. This additional feature can be enabled via the app, which gives you the chance to regulate the intensity levels and the massage features too.

Connectivity

foreo app For a first-timer, you would need to download the Foreo For You app and register your device on it. After a successful registration, turn on your BlueTooth on your phone and your device would connect automatically to the app if within a close connection range.

You wouldn’t be needing the app for your cleansing section; however, the app comes into play when you need to switch to using the massage treatments. The app is pretty easy to use and very direct to operate. However, if you still can’t find your way around using it, there is a video that explains everything you need to know about how to use and position the Luna 3 device on your face during the massage treatment. These are designed to target particular problem zones, such as shaping the jawline and de-plumping the under-eye area. Not to worry, the treatment only lasts for about 4 minutes.

How to use

luna 4

Dampen your face and apply your desired cleanser to the device. For the best result, use a Micro-Foam Cleanser. Gently press the start button twice. For cleansing mode, press the Universal button once while for the Glow Boost mode, quick-price twice. Use the touch point in a circular motion and glide the device over your face till you get the beep sound which signifies that the timer is off. Then proceed to rinse your face using water and the device, then dry. All these are very easy to do and would take just about 90 seconds max.

Battery life

The battery of the Luna 3 is long-lasting and according to its manufacturers, a single charge can last for about 650 uses. However, for the Luna 4, you get a USB rechargeable with only 100 use per single charge.

Final note

If you wear makeup daily, there is every possibility that some of these product gets stuck beneath your skin even after cleansing and the accumulation of these products over time may clog your skin. That is why you need a deep cleansing device such as the Luna 3 or Luna 4 to help do the tough job of eliminating that dirt. We couldn’t have been more excited seeing that a device does that with so minimal effort.

Overall, in terms of its design, technology, and other features, we see a wide margin between the Luna 3 and 4 with the latter having a better rating score than the former, despite its price. Notwithstanding both devices bring their A-game in their silicone bristles. If you are price-conscious, you may have to look towards the Luna 3 but if you are about the comfort and result, without minding the price, then the Luna 4 will do. So, with what you’ve read so far for the comparison, the decision is yours to make.

Till another time,

Stay flawless!
