FOREO LUNA 4 Review: Features, Pros, Cons and Who It Really Suits
The FOREO LUNA 4 is one of the best known facial cleansing devices on the market, and it is often the first name people see when they search for a silicone alternative to spinning bristle brushes. It promises a deeper cleanse and a firming facial massage in one tool, controlled either by buttons or through a phone app.
The FOREO LUNA 4 is a well made, waterproof silicone cleansing device that suits people who enjoy a tool-based routine and want something gentler and more hygienic than a nylon bristle brush. According to FOREO’s user manual, it offers 16 intensity levels, gentle, regular and deep cleansing settings, a separate firming massage mode and up to 600 one-minute uses per charge. It does not clean your skin better than a good cleanser and clean fingertips in any way that research has proven, and the firming mode is a massage rather than a lifting treatment. It is worth considering if you value comfort and convenience, but it is optional, not essential.
In short: a pleasant, durable and easy to clean device, but a luxury rather than a skincare necessity.
The American Academy of Dermatology advises gentle cleansing and warns that scrubbing or over-exfoliating can irritate skin and worsen acne, which is the lens this review uses.
Below we cover the features stated by the maker, who the LUNA 4 suits, its pros and cons, how to use it, what users commonly say and the alternatives worth comparing.

What the FOREO LUNA 4 Is and How It Works
The LUNA 4 is a handheld facial cleansing device with a soft silicone surface covered in raised touch-points. Instead of spinning like older bristle brushes, it vibrates using what FOREO calls T-Sonic pulsations. You apply your usual cleanser, switch the device on and move it over the face in small circles, and the vibration helps lift makeup, sunscreen and oil from the surface of the skin.
The back of the device has a smoother textured surface used for the firming massage mode. In this mode the device gives lower frequency pulsations that you glide upward over the face, similar in spirit to a manual facial massage. FOREO’s app lets you adjust intensity, follow guided routines and locate the device if you misplace it, but the device can also be used entirely with its buttons.
All specifications in this review come from FOREO’s published user manual. We have not tested the device ourselves, and features can change between production batches and regions, so check the listing before you buy.
LUNA 4 Features and Specifications
Here is a summary of the key features the maker lists. We have left out anything we could not confirm from FOREO’s own documentation.
| Feature | What FOREO states |
|---|---|
| Material | Body-safe silicone and ABS plastic |
| Intensity levels | 16, adjustable through the app |
| Cleansing settings | Gentle, regular and deep |
| Firming massage | Five manual patterns plus app-guided routines |
| Battery | Up to 600 uses per charge, based on one-minute sessions |
| Charging | USB cable, around two hours |
| Water resistance | Fully waterproof |
| Skin type versions | Sensitive, balanced and combination |
| App | Controls settings, guided routines and a device finder |
The three skin type versions differ mainly in the thickness of the touch-points. The sensitive version uses thinner, softer points, while the balanced and combination versions use thicker ones. If you are unsure, the sensitive version is the safer choice because it is less likely to irritate.
Who the LUNA 4 Suits and Who Can Skip It
A cleansing device is a comfort and convenience choice more than a skin health one. Whether the LUNA 4 is a good buy depends on how you like to cleanse and how your skin reacts to friction.
| Person | Good fit? | Why |
|---|---|---|
| Wears makeup and sunscreen daily | Often yes | Helps loosen residue with less rubbing by hand |
| Enjoys a ritual or facial massage | Yes | The firming mode adds a relaxing step |
| Oily or combination skin | Often yes | Thicker points help around the nose and chin |
| Sensitive skin | Maybe | Use the sensitive version, low intensity and short sessions |
| Rosacea, eczema or active inflamed acne | Usually no | Friction and vibration can aggravate irritated skin |
| Tight budget | No | A gentle cleanser and fingertips work well |

Pros and Cons of the FOREO LUNA 4
Every device has trade-offs. These are the main strengths and weaknesses based on the maker’s specifications and the general design of silicone sonic cleansers.
- Pro: silicone is non-porous and easy to rinse, so it tends to stay cleaner than nylon bristles.
- Pro: no replacement brush heads to buy.
- Pro: long battery life means infrequent charging.
- Pro: fully waterproof, so it can be used in the shower.
- Pro: three skin type versions let you choose a softer or firmer surface.
- Con: a high upfront cost for a tool that is not essential.
- Con: some features sit inside the app, which not everyone wants to use.
- Con: the firming massage has limited evidence for lasting results.
- Con: the battery is built in, so the device cannot be repaired easily when it ages.
For many people the deciding factor is simply whether they will use it. A device that sits in a drawer delivers nothing, while a simple cleanser used properly every night does real work.
Does the Firming Massage Mode Work?
The firming mode is the main thing that separates the LUNA 4 from basic cleansing brushes. It uses low frequency pulsations on the back of the device, and FOREO suggests gliding it upward along the jaw, cheeks and forehead.
Facial massage can feel relaxing and may make skin look briefly brighter and less puffy because of increased blood flow. However, there is no strong evidence that massage alone lifts sagging skin, builds collagen or reduces wrinkles in a lasting way. Our article on whether anti-aging face massages work looks at what the research does and does not show.
Apply a few drops of serum or facial oil before using the firming mode so the device glides instead of dragging. Keep the pressure light and stop if your skin turns red or feels warm.
How to Use the FOREO LUNA 4 Safely
Using the device gently is more important than using the highest setting. These steps follow the general directions in FOREO’s manual and standard dermatology advice about gentle cleansing.
Remove eye makeup first
Use a separate remover for the eye area, which the device should not touch.
Wet your face and apply cleanser
Use a gentle, non-gritty cleanser rather than a scrub.
Wet the device and choose a low setting
Start on the gentle setting and increase only if your skin is comfortable.
Cleanse in small circles
Move over each area for a few seconds, for about one minute in total.
Rinse your face and the device
Rinse off all cleanser and rinse the silicone under warm water.
Pat dry and moisturise
Follow with moisturiser, and sunscreen in the morning.
Clean the device regularly
Wash with mild soap and water, dry it and store it away from others.
FOREO states the device is suitable for daily use. If your skin is sensitive, start with once a day or every other day and increase slowly.
What Users Commonly Say About the LUNA 4
Owner feedback on retail sites tends to fall into a few repeated themes. We summarise them here in general terms rather than quoting individual reviews.
- Many owners describe it as soft and comfortable, especially compared with bristle brushes.
- The long battery life is frequently praised.
- Some users feel their skin looks smoother or cleaner, while others notice little change.
- A common complaint is the price relative to simpler devices.
- Some people find the app unnecessary or awkward to pair.
- A minority report redness or breakouts, often when using high intensity or long sessions.
Mixed feedback is normal for any skincare device because results depend on skin type, cleanser choice and how gently the device is used.
Alternatives to the FOREO LUNA 4
If the LUNA 4 does not fit your budget or needs, several alternatives offer a similar basic cleanse.
| Option | How it compares | Best for |
|---|---|---|
| Smaller FOREO LUNA mini models | Compact and simpler, with fewer settings | Travel and basic cleansing |
| Other silicone sonic cleansers | Similar vibration and silicone surface, fewer app features | Value seekers |
| Manual silicone face scrubbers | No power, gentle and cheap | Minimalists and sensitive skin |
| Soft washcloth | Mild friction, washable | Budget routines |
| Clean fingertips and a good cleanser | No device needed | Most skin types, especially reactive skin |
Our round-up of the best silicone facial brush options covers more budget-friendly silicone cleansers if you like the feel of silicone but not the price.
LUNA 4 vs Spinning Bristle Brushes
Before silicone sonic cleansers became popular, most cleansing devices used rotating or oscillating nylon bristle heads. The two designs feel quite different on the skin and need different care.
- Bristle brushes scrub more actively, which some oily skin types like but sensitive skin often dislikes.
- Bristle heads trap water, oil and dead skin, so they need replacing every few months.
- Silicone surfaces dry faster and are easier to rinse clean.
- Silicone devices usually feel softer, which reduces the risk of over-exfoliating.
- Bristle brushes can remove more flaky skin, but that is rarely necessary every day.
If you have used a bristle brush before and found it harsh, a silicone device like the LUNA 4 is likely to feel gentler. If you liked the stronger scrub of bristles, you may find silicone too mild. Either way, the AAD’s advice on exfoliating safely at home is a useful guide to how much friction your skin can take.
Dos and Don’ts
Try This
- Use a gentle, non-gritty cleanser
- Start on the lowest comfortable setting
- Keep sessions to about one minute
- Clean and dry the device after use
- Moisturise after cleansing
Avoid This
- Use it on broken, sunburnt or inflamed skin
- Press hard or scrub
- Pair it with scrubs or strong acids every day
- Share the device with others
- Expect the firming mode to lift sagging skin
Honest Limits
There is no strong independent evidence that the LUNA 4 cleans the skin significantly better than a well chosen cleanser applied with clean hands. Much of its appeal is comfort, routine and hygiene compared with bristle brushes, which are real benefits but not medical ones.
The device will not treat acne, rosacea, pigmentation or deep wrinkles. It can support a routine that already includes the right active ingredients and daily sunscreen, but it cannot replace them. If you have acne, the AAD acne skin care tips warn that scrubbing can make breakouts worse, so gentle use matters more than intensity.
Stop using the device if you notice stinging, persistent redness, rash or new breakouts. Avoid it after peels, laser treatments, microneedling or injectables until your practitioner says it is safe, and do not use it on open wounds or active infections.
When to See a Dermatologist
- Your skin stays red, stings or peels after using a cleansing device.
- You have acne that is not improving with gentle over-the-counter care.
- You have rosacea, eczema or another skin condition and want to know if a device is safe.
- You notice any changing mole or spot on your face.
