WAU REN Ultrasonic Facial Scrubber
An editorial profile of WAU’s REN ultrasonic facial scrubber, covering its published 25 kHz frequency, the positive and negative ion modes, the 10-minute cut-off and IPX4 rating, and the contraindications WAU publishes for it.
At a glance
REN is one of two devices in this batch whose listing publishes contraindications, and the ones it gives are the right ones for the tool: not on broken or inflamed skin, not over implants or braces, and not within a month of surgery. It also publishes its defining number, 25 kHz, and gives directions specific enough to follow - the working angle, the gel, the duration of each mode. The gap is the opposite of the usual one here. Where most of the range omits safety information, this page omits frequency of use, and for a device with an abrasive edge that is the parameter most likely to cause harm through enthusiasm: the page says to use it "regularly" and never says how often. The 25 kHz figure also stands alone, with no power or amplitude behind it. A South African price, availability and warranty position still need to be established.
- Useful for
- Readers comparing ultrasonic cleansing tools on published frequency and stated contraindications.
- Not ideal for
- Anyone with an active skin condition, or needing published guidance on how often to use it.

- Current image rights
- verified — checked 2026-09-08. Hero is the advertiser’s own packshot from the Awin datafeed we are approved on; gallery images are commissioned AI lifestyle scenes, disclosed as such. AI studio packshots and baked-text infographics were withheld. Recorded on the operator’s attestation of the programme creative terms; written advertiser confirmation of image reuse remains outstanding. This is the same basis the 7 September 2026 review withdrew these images over, and it has not yet changed.
- Hands-on testing
- not tested. Publisher confirmed 6 September 2026 that none of the listed products has been personally tested.
- Product identity
- verified — checked 2026-09-08. WAU Global official product page https://wauglobal.com/products/ren-ultrasonic-facial-scrubber read 2026-09-08; exact product-title match. JSON-LD Product schema on that page gives GTIN-13 4673728150270, SKU BPW-003 and variant 52314216661299. Imported from Awin WAU programme, advertiser 124878, datafeed 114261; publisher account 3062097. Programme approval recorded 2026-08-31 09:46 (approval email from no-reply@awin.com), merchant profile https://ui.awin.com/affiliate/3062097/merchant-profile/124878/overview. Campaign PIN-20260907-01M1X9RSX072DWA6N66FCC3FCB. The workbook’s "Website Functions / Features" field is truncated at 1200 characters, so the complete feature list, directions and any contraindications were read from the live product page rather than from the intake row.
- South African market
- verified — checked 2026-09-09. Checked against WAU Global's own published pages on 2026-09-09. DELIVERY: ships to most countries worldwide; South Africa appears in the site's country/region selector. International delivery quoted at 7-14 business days, after 1-2 business days' processing, via UPS, FedEx, DHL or USPS at WAU's discretion. Orders over USD 50 ship free; otherwise the charge is shown only at checkout. CURRENCY: the selector lists 'South Africa (USD $)' - WAU prices South African buyers in US dollars and does not offer rand. TAX AND DUTIES - WAU'S PAGES CONFLICT: the Shipping Policy states 'For the tax: WAU Global Will pay for the tax, we will not charge the tax fee from our customers', while the Terms of Service state 'posted prices do not include taxes, shipping, handling, customs or import charges' and that the customer 'will pay ... all applicable taxes'. Both cannot hold for an import into South Africa. Recorded as unresolved; the profile tells readers to expect to pay South African VAT, customs duty and courier clearance fees, which is the Terms position and the safe assumption. Written confirmation is being sought. RETURNS: 30 days from receipt, unused and undamaged, in original packaging with proof of purchase. The buyer must contact info@wauglobal.com first - 'items sent back to us without first requesting a return will not be accepted'. WAU says it will send a return shipping label if the return is accepted, but does not state whether that label is prepaid for international customers; returning a device from South Africa could be costly, so this is recorded as an open ambiguity rather than assumed either way. Refunds are issued to the original payment method within 10 business days of inspection. WARRANTY: WAU's FAQ says 'most products come with a manufacturer's warranty. Check the product description for details.' None of the 23 WAU product descriptions read for this catalogue states a warranty duration or its coverage, so at product level the warranty terms are a checked absence. WAU separately undertakes to replace a defective product free of charge, but does not say who pays international shipping, customs or VAT on a warranty claim.
- Safety documentation
- verified — checked 2026-09-09. Official WAU user guide (REN Ultrasonic Skin Scrubber, model BPW-003) obtained and read 2026-09-09 from wau.ru; English section used. The model number matches this record's sourceSku, and it settles an ambiguity: wau.ru carries both a /ren page and a UMI ultrasonic scrubber page for a similar device, and only the manual printed BPW-003 belongs to this product. PRECAUTIONS as written - the device is for individual use only and must not be shared; use it strictly as intended, keeping to the recommended duration and frequency; 'use caution when applying the device near areas with metal implants or prostheses'; 'do not use the device in areas affected by venous or arterial disorders, or for patients with thrombophlebitis or a history of blood clotting disorders'; do not drop it; do not disassemble, modify or repair it. Warranty stated as 1 year. Authorised manufacturer representative given as PERFECT SQUARE LIMITED, Auckland, New Zealand.

PowderedPurple assessment
REN is one of two devices in this batch whose listing publishes contraindications, and the ones it gives are the right ones for the tool: not on broken or inflamed skin, not over implants or braces, and not within a month of surgery. It also publishes its defining number, 25 kHz, and gives directions specific enough to follow - the working angle, the gel, the duration of each mode. The gap is the opposite of the usual one here. Where most of the range omits safety information, this page omits frequency of use, and for a device with an abrasive edge that is the parameter most likely to cause harm through enthusiasm: the page says to use it "regularly" and never says how often. The 25 kHz figure also stands alone, with no power or amplitude behind it. A South African price, availability and warranty position still need to be established.
Pros and cons
Pros
- The ultrasonic frequency is published as 25 kHz, so the device can be compared on its defining specification
- WAU publishes contraindications, including a one-month post-surgery exclusion
- The directions are specific down to the working angle and the duration of each mode
Cons
- No usage frequency is published for an abrasive-edged tool where over-use is the main risk
- No power, amplitude or ion output, so 25 kHz stands without any dose context
- IPX4 is quoted without saying which parts may be rinsed or how the edge should be cleaned
What to examine
- Merchant listing title
- REN - Ultrasonic Facial Scrubber. Quoted as published by WAU.
- Ultrasonic frequency
- 25 kHz, published as a figure. WAU does not publish an amplitude or power output alongside it.
- Modes
- Two ion modes. Deep cleansing uses positive ions, which WAU says opens pores; moisturising uses negative ions, used after applying a serum or cream.
- Timer
- A smart timer with automatic shutdown after 10 minutes.
- Water resistance
- IPX4.
- Battery
- Up to 100 minutes of operation, with a 2-hour charge over Type-C. No capacity is published.
- Design
- A magnetic cover over the working edge, which WAU cites for hygienic storage.
- Published contraindications
- WAU states: do not use on damaged skin, inflammation or sunburn; avoid areas with metal implants, pins or braces; and do not use for one month after surgery.
- What WAU does not publish
- No ultrasonic power or amplitude, no ion output figure, no battery capacity, no blade material, and no guidance on how often to use it.
- Manufacturer documentation
- WAU user guide for model BPW-003, obtained 9 September 2026 from WAU's Russian site: https://wau.ru/upload/iblock/6e4/d7apddndkqxbn0hsg7io5su05e4eo2be.pdf . It is more specific than the English product listing, and this profile's figures and cautions are taken from it where the two differ.
How to use
For deep cleansing, apply a desincrustation gel, select the mode and move along the massage lines at about 40 degrees for 3-5 minutes. For moisturising, apply a serum or cream, switch mode and work over the skin for 3-5 minutes. Follow the instructions supplied with the device.
Limitations and cautions
PowderedPurple has not tested this device and does not present it as a treatment for blackheads, acne or any skin condition. WAU's own user manual (model BPW-003) says not to use it over areas affected by venous or arterial disorders, or if you have thrombophlebitis or a history of a blood clotting disorder, and to use caution near metal implants or prostheses. It is for one person only and should not be shared. Keep to the session lengths and frequency WAU gives rather than scraping for longer - the working edge is a steel spatula vibrating against skin, and over-use leaves it red and sore. Do not use it on broken, inflamed or sunburnt skin, or over active acne lesions. Speak to a healthcare professional before use if you are pregnant, have a skin condition under treatment, or take medication that thins the skin, such as isotretinoin.
Product information from the source
The manufacturer specification describes this product as follows. These are source statements, not PowderedPurple conclusions, and they have not been independently verified.
- WAU says REN "combines ultrasonic vibration and ionic technology to deeply cleanse pores, improve microcirculation and enhance the effectiveness of your skincare products", and that ultrasonic vibration at 25 kHz "gently removes dirt, dead cells and cosmetic residues".
- It lists results with regular use as "clean pores without blackheads and comedones", "improved skin texture and tone", "accelerated metabolism and collagen production" and "smoothed fine wrinkles and increased skin elasticity".
- These are the manufacturer’s own statements, quoted from its product page. WAU cites no supporting evidence and PowderedPurple has not verified them.
