To use an ultrasonic skin scrubber, start on clean, damp skin, hold the spatula at a shallow angle and glide it slowly upwards in short strokes, keeping the skin wet throughout. Most scrubbers have three modes: exfoliation to lift away dead surface cells, extraction support to help clear congestion, and infusion to help serums feel absorbed. Use it once or twice a week, gently, and finish with hydration.
Key takeaways
- An ultrasonic skin scrubber is a spatula that vibrates at very high, ultrasonic frequency to help exfoliate and refine the look of skin.
- Skin must stay wet or well covered in product; never use the spatula on dry skin.
- Exfoliation and extraction modes are best once or twice a week; infusion can be used more often.
- Pair each mode with the right product: an exfoliating foam, a pre-extraction gel or a serum.
- Light pressure and slow strokes give smoother-feeling skin without irritation.
What is an ultrasonic skin scrubber?
An ultrasonic skin scrubber is a handheld device with a flat metal spatula that vibrates at an ultrasonic frequency, too fast for you to see or hear. When it glides across wet skin, those vibrations help loosen dead skin cells and surface debris, so skin feels smoother and looks brighter.
It is different from a sonic brush, which uses slower, audible vibrations through soft bristles to cleanse. Our guide to sonic vs ultrasonic skin devices explains the difference in detail, and our sonic cleansing brush guide covers brushes on their own.
The bt-micro fusion Ultrasonic Skin Scrubber from Bio-Therapeutic is a home-use version with three modes: exfoliation (“Exfol”), extraction support and infusion.
What do the three modes do?
| Mode | What it does | Pair with | How often |
|---|---|---|---|
| Exfol (cleanse and exfoliate) | Helps lift away dead surface cells and residue for smoother-feeling skin | An exfoliating foam on damp skin | Once or twice a week |
| Extraction support | Helps loosen and lift surface congestion from pores | A pre-extraction gel | Once a week or less, on congested areas |
| Infusion | Gentle vibration that helps serums and moisturisers feel absorbed | A water-based serum, toner or moisturiser | Up to several times a week |
How do you use an ultrasonic skin scrubber, step by step?
Always follow your device’s manual for angles, settings and timings. This general routine works for most people.
Mode 1: Exfoliation
- Cleanse to remove makeup and SPF.
- Apply your exfoliating medium to damp skin. Bio-Therapeutic designed Aquafuse FoamPeel, an AHA foam with lactic, glycolic, malic and tartaric acids, to pair with the bt-micro fusion in Exfol mode.
- Switch to Exfol mode and hold the spatula at a shallow angle, as shown in the manual.
- Glide slowly upwards and outwards in short strokes, working one area at a time. You may notice a fine mist as the vibration meets water: that is normal.
- Keep the skin wet, re-misting or adding foam as needed.
- Rinse and move to hydration.
Mode 2: Extraction support
- After exfoliating, apply a pre-extraction gel to congested areas such as the nose, chin and forehead. Decongest Treatment Gel, with jojoba esters, pineapple enzymes and tea tree, is made to pair with the bt-micro fusion.
- Leave it for the time stated on the pack to soften the area.
- Use extraction mode with very light strokes over the congested zone only.
- Rinse and soothe. Never squeeze or press hard.

Mode 3: Infusion
- Apply a water-based serum or hydrating fluid. Restyfluid, with hyaluronic acid and peptides, works well here and doubles as a conductive medium for devices.
- Switch to infusion mode and glide gently over the skin, using the side of the spatula the manual recommends.
- Follow with moisturiser, and SPF in the morning.

How often should you use an ultrasonic skin scrubber?
For most skin types, exfoliation mode once or twice a week is plenty. Oilier, more resilient skin may tolerate twice a week; drier or sensitive skin is often happier with once. Infusion mode is gentler and can be used more often.
Count your scrubber as part of your exfoliation for the week, not an extra. If you also use acids, retinoids or scrubs, reduce one of them so you do not overdo it. Signs you are overdoing it include tightness, stinging when you apply products, redness and shiny, taut-looking skin.
Which skin types suit an ultrasonic skin scrubber?
- Oily and congested skin: often the biggest fans, especially of extraction support mode.
- Normal and combination skin: great for a weekly smoothing step and for helping serums feel absorbed.
- Dry skin: use exfoliation mode sparingly and infusion mode more often.
- Sensitive or reactive skin: start with infusion only, and patch test before trying exfoliation.

Who should avoid an ultrasonic skin scrubber?
Do not use it over broken skin, active inflamed breakouts, cold sores, sunburn or irritation. Check with your GP first if you are pregnant, have a pacemaker or other implanted electronic device, or have had recent facial procedures, and always read the manufacturer’s safety list.
Keep the spatula clean between uses. Our guide to cleaning and caring for skincare devices covers it, and you can explore more tools on our Bio-Therapeutic page.

Frequently asked questions
Does an ultrasonic skin scrubber hurt?
It should not. Most people feel a gentle buzz or nothing at all, and you may see a fine mist from the water on your skin. If it stings or feels scratchy, your skin is probably too dry or you are pressing too hard. Add more water or product, lighten your touch and keep the spatula moving slowly.
Can I use an ultrasonic skin scrubber on dry skin?
Never use the spatula on dry skin: it needs water or a product to work properly and to glide comfortably. On a dry skin type, keep exfoliation mode to once a week or less, use plenty of hydrating product and rely more on infusion mode, which is gentle and can help moisturisers feel absorbed.
Is an ultrasonic skin scrubber good for blackheads?
Used with a softening pre-extraction gel, extraction support mode can help loosen and lift surface congestion, so pores may look clearer. It works best as part of a gentle routine with regular cleansing and exfoliation. It will not remove every blackhead in one session, and you should never press hard or squeeze afterwards.
Can I use an ultrasonic skin scrubber with retinol?
Use them on different evenings. Retinoids can make skin more sensitive, and combining them with ultrasonic exfoliation on the same night may lead to irritation. Use the scrubber on a retinoid-free evening, keep infusion mode for gentle, hydrating serums, and wear SPF every day.
