Foreo Luna 4 Cleansing Device Review

Overview

The Foreo Luna 4 is a high-end silicone cleansing device designed to give a deeper yet gentler cleanse than your hands alone. It uses Foreo's signature T-Sonic pulsations through soft silicone bristles to loosen sunscreen, oil, and debris while staying non-abrasive on the skin.

This latest generation Luna feels more refined than earlier versions. The bristles are softer and more flexible, the shape is easier to grip, and there are three cleansing modes (Gentle, Regular, and Deep Cleanse) with multiple intensity levels. It is fully waterproof, charges via USB, and one charge can last for months depending on how often you use it.

The price is undeniably steep for a cleansing tool. For most shoppers, the big question is whether it offers results that justify the investment: clearer pores, smoother texture, and better performance from the rest of your skincare.

Used correctly, the Luna 4 can deliver a more thorough cleanse with less friction than washcloths or traditional bristle brushes. However, it is not a magic wand, and it works best as one part of a solid routine rather than a stand-alone solution.

Who it's for

Best for

Normal to combination skin. If you get a bit oily through the T-zone but feel dry or normal on the cheeks, Luna 4 can help keep pores clear without stripping. The combination of soft silicone and adjustable intensity makes it easy to fine tune for different areas of the face.

Oily and congestion-prone skin. Those who struggle with clogged pores, blackheads on the nose, or that perpetually slightly-grimy feeling after a day in makeup or sunscreen tend to appreciate the deeper cleanse. Used consistently with a gentle cleanser, it can help reduce the number of clogged pores over several weeks.

Busy, low-maintenance users. If you want a quick, timed routine that requires very little thought, the Luna 4's built-in timer guides you through a roughly one-minute cleanse. The long battery life and fast rinse-cleaning suit people who never remember to charge or care for more delicate tools.

Skincare enthusiasts who layer actives. If you invest in serums with ingredients like vitamin C, niacinamide, or retinoids, getting a truly clean but non-stripped canvas helps those formulas work better. Luna 4 can lift more residue and oil than hands alone, making your actives a bit more efficient.

Not ideal for

Very reactive or inflamed skin. If you have a compromised barrier, active eczema or dermatitis, or very angry rosacea flares, adding any cleansing device is usually not a good idea. In that situation, the priority should be calming and repairing the barrier with the gentlest possible routine.

Individuals on a tight budget. The Luna 4 is an investment tool, not a basic necessity. If you are choosing between this and a solid gentle cleanser plus moisturizer, prioritize the products first.

Those who want full makeup removal in one step. The Luna 4 pairs best with a proper first cleanse to dissolve heavy makeup or long-wear sunscreen. If you expect it to take off a full glam face in one minute with a basic gel cleanser, you will be disappointed.

How it feels and performs

Texture and comfort on skin. The Foreo Luna 4 uses ultra-soft silicone touchpoints that feel like a flexible, velvety brush head. On Gentle mode, it feels like a light massage with a cushiony texture and minimal drag. On the highest intensities and deeper cleanse mode, you feel more vigorous vibrations but the silicone tips still do not feel scratchy or abrasive.

Noise and handling. The device hums rather than rattles, and the sound is relatively soft in a bathroom setting. The body has a slightly grippy finish that is easy to hold even with wet, soapy hands. The teardrop shape helps you reach around the nose and chin while the larger center area covers cheeks and forehead efficiently.

Cleansing power. On Regular mode with a good non-stripping cleanser, the Luna 4 visibly improves how clean the skin looks and feels compared with just using fingers. Pores, especially around the nose and between the brows, tend to look less congested over time. Makeup and sunscreen residue along the hairline and jaw are easier to lift away because the silicone tips physically move product and water into creases.

Results over time. Most users notice an immediate smoothness after the first few uses simply because more dead skin and residue are removed. Texture and blackhead improvement usually become more obvious after 2 to 4 weeks of consistent use, especially if you are also limiting pore-clogging products. Breakout-prone skin may see fewer tiny surface bumps as cleansing becomes more thorough.

Impact on dryness and sensitivity. Used aggressively or with a foaming, high-pH cleanser, the Luna 4 can leave skin feeling tight or overworked, particularly around the cheeks. Used on a lower intensity with a hydrating, low-foam cleanser, it typically feels gentle enough for daily use on normal and combination skin. Sensitive users should treat it like a mild extra exfoliation step and keep use to a few times per week at first.

Hygiene and upkeep. The nonporous silicone is a big advantage over traditional brush heads. It does not hold on to product, odor, or water in the same way, so it is less likely to harbor bacteria if you rinse it thoroughly and let it air-dry. There are no brush heads to replace, which offsets some of the initial cost over time.

Battery life and app features. The Luna 4 charges with a small USB cable and a full charge can last many weeks, sometimes months, of daily use. There is an optional app that can control modes, set routines, and record usage, but you can also use the device fully without ever pairing it. The convenience is that once you find settings you like, you rarely have to think about them again.

How to use for best results

To get the most from the Foreo Luna 4, treat it as part of a full cleansing system rather than a replacement for good products. Here is a step by step routine that keeps skin clean without overdoing it.

Step 1: Remove heavy makeup or sunscreen

If you wear long-wear foundation, waterproof mascara, or thick sunscreen, start with an oil or balm cleanser. Massage it in with your hands to break everything down, then rinse or gently wipe away. The Luna 4 is much more effective when it is not fighting through layers of makeup.

Step 2: Apply your regular cleanser

Choose a gentle, non-exfoliating cleanser without scrub particles. Avoid cleansers that already contain physical exfoliants or strong acid blends, since the combination with the device can be too much. Wet your face and the Luna 4, then apply your cleanser either to your skin or directly onto the silicone bristles.

Step 3: Choose the right mode and intensity

For most people, Regular mode at a mid-level intensity is plenty. If your skin is easily irritated, start with Gentle mode on a low setting. Reserve Deep Cleanse mode for very oily or particularly congested areas like the nose and chin, and do not use it every single day until you are sure your skin tolerates it well.

Step 4: Follow the built-in timer

Move the Luna 4 in small circular motions over your face, letting the device guide you. A typical pattern is 15 seconds per cheek, 15 seconds for the forehead, and 15 seconds for the nose and chin, adjusting for your face size. When the device pauses or signals that the routine is done, stop rather than going back over the same areas repeatedly.

Step 5: Rinse thoroughly and dry

Rinse your face well until all cleanser is gone. Then rinse the Luna 4 under warm running water and, if needed, use a drop of gentle soap on the bristles for a deeper clean. Pat the device dry with a towel or let it air dry in a clean, ventilated space, not pressed against other wet items.

Step 6: Apply your skincare

Because Luna 4 can slightly increase product absorption, be mindful of what you apply immediately afterward. This is an ideal time for hydrating toners, essences, and calming serums. If you use strong actives like retinoids or exfoliating acids, consider using them on nights when you are not using the device or keep the device on its gentlest settings.

Frequency guidelines

Normal to oily skin generally does well with once daily use at night. Very oily or acne-prone users may tolerate two uses per day, but this is rarely necessary and can sometimes lead to dryness. Sensitive or easily flushed skin should start with two to three times per week and increase only if the skin stays calm and comfortable.

Pros and cons

Pros

• Soft, nonporous silicone bristles feel comfortable and are easy to keep clean.
• Adjustable modes and intensities let you customize cleansing for different areas and skin types.
• Provides a noticeably more thorough cleanse than hands alone, especially around the nose and hairline.
• Long battery life and no replacement brush heads reduce ongoing maintenance and cost.
• Fully waterproof design makes it safe and convenient to use in the shower.
• Helps prep skin so serums and treatments absorb more effectively.

Cons

• High upfront price compared with basic cleansing tools and simpler silicone brushes.
• Can be too much for very sensitive, compromised, or inflamed skin if overused.
• Requires a separate first cleanse to properly remove heavy makeup and sunscreen.
• App features may feel unnecessary or fussy for those who prefer truly simple routines.
• Settings and modes can feel overwhelming at first if you are not tech comfortable.

Final verdict

The Foreo Luna 4 is a well-designed, genuinely gentle cleansing device that does what it promises for the right user. It delivers a cleaner, smoother-feeling complexion than washing with hands alone, and it does so without the scratchiness or bacterial concerns of older-style brush heads.

If you already have a decent routine, wear sunscreen or makeup daily, and care about keeping pores clear, the Luna 4 can be a worthwhile upgrade that you will likely use for years. It is especially compelling if you value low-maintenance tools that hold a charge forever and are simple to rinse off and keep sanitary.

On the other hand, if your skin barrier is fragile, you are on a very limited budget, or you prefer the absolute minimalist approach, you may be better off focusing on gentle cleansers and moisturizers instead of adding a device. The Luna 4 is a luxury that enhances good habits rather than replacing them.

Overall, the Foreo Luna 4 earns its place as a premium cleansing tool: not essential for everyone, but highly satisfying and effective for people who want a deeper, more comfortable cleanse with long-term payoff.

FAQ

Is the Foreo Luna 4 really worth the price compared with cheaper silicone cleansing brushes?

Cheaper silicone cleansing brushes can mimic the general idea of the Luna 4, but the differences show up in the details. The Luna 4 has more refined, softer silicone tips, consistent T-Sonic pulsations, and multiple modes and intensities that allow for much more customization. It is also fully waterproof with long battery life and does not require head replacements. If you are committed to using a device regularly and can afford it, the Luna 4 tends to provide a more comfortable, reliable experience than budget alternatives, which may feel harsher or break down sooner.

Can the Foreo Luna 4 worsen acne or cause breakouts?

Used correctly, the Luna 4 is more likely to help with congestion than to worsen it, because it improves how thoroughly you remove oil, sweat, and residue. Breakouts can occur temporarily if you suddenly start deep cleaning skin that has been under-cleansed for a long time, or if you pair the device with harsh cleansers and overuse it. To minimize risk, start slowly, keep intensity at a moderate level, and avoid using it on open pimples or very inflamed areas until they calm down. Consistent, gentle use with a simple, non-comedogenic cleanser is the safest approach for acne-prone skin.

How often should I use the Foreo Luna 4 if I have sensitive skin?

If your skin is on the sensitive side, begin with using the Luna 4 two to three times per week on Gentle mode and a low intensity. Pay attention to signs of irritation such as lingering redness, tightness, or stinging when you apply products afterward. If your skin stays calm, you can slowly increase frequency to every other night, and only move up to daily use if your barrier feels strong and comfortable. There is no benefit to forcing daily use if your skin does better with less frequent, very gentle cleansing.

What type of cleanser works best with the Foreo Luna 4?

The Luna 4 pairs best with low-foam, non-exfoliating gel, cream, or milk cleansers that do not contain scrub particles or strong acid blends. These formulas allow the device to provide the physical stimulation while the cleanser handles oil and debris, without creating a double-exfoliation effect. Avoid clay-heavy masks, gritty scrubs, or cleansers with walnut shells or similar particles when using the device. If you like active cleansers with acids, reserve them for days you skip the Luna 4 or keep the device on the very gentlest settings.

How long does a Foreo Luna 4 last, and what about warranty and maintenance?

The Luna 4 is built as a long-term device and, with normal home use and proper care, can last many years. The silicone body does not require replacement brush heads, which keeps ongoing costs low, and the rechargeable battery typically holds a charge for weeks at a time. Foreo usually offers a limited warranty period against manufacturing defects, so it is worth registering your device and keeping your proof of purchase. For maintenance, rinse it thoroughly after each use, occasionally wash with a mild soap, avoid harsh solvents or alcohol, and store it where it can dry fully between uses.
