Short answer

FOREO's own method for its LUNA 4 is short: remove your makeup, dampen your face and apply cleanser, press the power button, then glide the soft silicone touchpoints in circular motions, with no pressure, until the built-in timer turns it off after about a minute. Rinse and pat your face dry. FOREO makes the LUNA 4 for sensitive, balanced and combination skin, with no brush heads to replace.

At a glance

Best for

  • A one-minute cleanse with a timer that turns the device off for you
  • Cleansing in the shower: FOREO says it can be used there
  • Never buying replacement brush heads

Skip it if

  • You don't want a phone app at all: FOREO's app is needed once, before first use, to unlock the device
  • You want nylon bristles: LUNA 4 uses soft silicone touchpoints
  • You have a skin condition such as eczema or have had a cosmetic procedure such as Botox: FOREO advises asking your physician or skincare professional first

What we like

  • Built-in timer of about one minute
  • Three cleansing modes: Gentle, Regular and Deep
  • Firming massage mode on the back of the same device
  • Travel pouch and USB charging cable in the box, per FOREO

Good to know

  • Needs the FOREO For You app once, before first use, to unlock it; after that it works without the app
  • Comes in three versions: FOREO makes it for sensitive, balanced and combination skin
  • FOREO recommends no more than 3 minutes at a time
  • USB charging; don't use it while it's charging

How FOREO says to use it

Start with a clean, damp face

FOREO says all makeup should be removed before the cleansing routine. Dampen your skin and apply cleanser; FOREO's blog says to wet the LUNA 4 too, and FOREO recommends its own LUNA Micro-Foam Cleanser 2.0.

Glide, don't press

FOREO says: "There is no need to use any pressure when using LUNA 4." Use circular movements on the cheeks and forehead and glide up and down the nose. FOREO asks for particular care under the eyes and says not to bring the device into contact with the eyelids or eyes.

Let the timer set the time

Pressing the power button starts Regular mode, and the built-in timer turns the device off after about a minute. The app can set a cleanse of up to 240 seconds, but FOREO recommends no more than 3 minutes at a time.

Pick the intensity

LUNA 4 has Gentle, Regular and Deep cleansing modes, switched with the two buttons on the back. FOREO's blog says to choose them for different areas of your face and neck. All 16 intensities can be set in the app over Bluetooth.

How to use it

  1. Remove all makeup, dampen your skin and apply cleanser to your face. Wet the LUNA 4 too.
  2. Press the power button to start Cleansing mode (it starts on Regular). Switch to Gentle or Deep with the two mode buttons.
  3. Glide the silicone touchpoints in circular motions over your face and neck, with no pressure, until the built-in timer turns the device off.
  4. Rinse your face, neck and the device, then pat your face dry.
  5. Optional firming massage: apply FOREO serum to clean, dry skin, press the power button and then quickly double-press it, and glide the back of the device outward, following the shape of your face, until the timer turns it off. Continue with your usual skincare routine.
  6. To clean it, wash the brush surface with water and soap, rinse with warm water, and pat dry with a lint-free cloth or towel.

Steps from FOREO's LUNA 4 user manual and its MYSA blog. FOREO says to avoid clay-based, silicone-based or grainy cleansers, exfoliators and scrubs, which may damage the silicone touchpoints, and never to clean it with products containing alcohol, petrol or acetone.

Questions buyers ask

How long should I use it?

The built-in timer turns it off after about a minute. FOREO recommends that you do not use LUNA 4 for more than 3 minutes at a time.

Do I need to press it into my skin?

No. FOREO says there is no need to use any pressure: use circular movements on the cheeks and forehead, and glide up and down the nose.

Can I use it every day?

FOREO says it is safe and gentle enough to use every day, either morning or night.

Can I use it in the shower?

Yes, FOREO says you can use it in the shower. Make sure it is completely dry before charging, don't use it while charging, and don't leave it submerged in water.

Do I need the app?

Once. FOREO's app unlocks and registers the device before first use; after that you can use LUNA 4 manually.

Does it need replacement brush heads?

No. FOREO says no replacement brush heads are required.

The bottom line
