What?!
Yes, the social media skincare world is serving up yet another wild trend designed to turn a small grain of truth into a viral skincare disaster. The latest viral 'toothbrush for face cleansing' trend promotes the use of toothbrushes as exfoliating tools — suggesting they will get skin ‘extra clean’ and buff it into baby-skin softness.
The Grain of Truth
As with many social media skincare trends, the concept is often rooted in a grain of truth before being taken to an extreme where it is neither accurate nor safe. Mechanical exfoliation—the physical removal of dead skin cells from the skin's surface—has been practiced for decades (remember the sandpaper-like gritty scrubs of the '80s?), but creators promoting this latest trend have taken that concept to an ill-advised extreme by suggesting toothbrush bristles as a legitimate exfoliation tool. However, there is no comparison between the sophisticated physical and chemical exfoliants available today and harsh toothbrush bristles, which are categorically not designed for use on the skin.
Is a Soft Toothbrush OK?
A toothbrush, no matter how ‘soft’ the bristles claim to be, is designed to scrub teeth, not delicate facial skin. Teeth are made primarily of calcium phosphate crystals, and their outer enamel is the hardest substance in the human body.
This incredibly tough mineral layer is strong enough to withstand brushing with even firm bristles and can tolerate daily mechanical friction. Skin cannot. Skin isn't enamel.
What Are The Risks?
Brushing your face with a toothbrush (or any aggressive, abrasive brush) can create tiny, invisible microtears on your skin's outer layer, damage your moisture barrier, and trigger breakouts, sensitivity, or the melanin overproduction that leads to hyperpigmentation — especially in darker skin tones. Your skin is made up of millions of living cells that form a protective barrier to keep moisture in and irritants out. Overexfoliating and overcleansing the skin strips the barrier, leading to redness, dryness, and prolonged sensitivity.
Some of this trend's content creators even use the hashtag #acneprone to promote this method of cleansing for those with acneic skin. Although acne-prone skin can benefit from chemical exfoliation, scrubbing an abrasive brush over active acne can spread bacteria, worsen inflammation and irritation, and exacerbate breakouts. It can also damage the skin barrier, leading to increased water loss (transepidermal water loss, or TEWL), which leaves the skin dehydrated. In response, the skin may produce more oil to compensate, while dead skin cells accumulate more readily — making clogged pores and acne even worse. There's only so much you can scrub off your face before you literally start scrubbing away your natural protective barrier.
What About Facial Brushes?
We do not recommend the use of facial brushes for numerous reasons (risk of over cleansing, poor tool maintenance, abrasive tips, incorrect usage, potentially destroying your acid mantle, bacteria-trapping bristles, need we go on?) and will always recommend hands or soft cloths instead. If you are wedded to the idea of using a mechanical cleansing tool, we would suggest only using one designed with gentle rounded silicone tips rather than harsh, nylon bristles. They are easier to clean and rely on vibration rather than physically scratching your skin.
What to Do Instead
Instead of a damaging DIY dental approach, stick with gentle, barrier-respecting cleansers and chemical facial exfoliants.
-
Gentle Cleansers: For most skin types, a gentle cleanser applied with your hands and removed with a soft cloth will provide all the deep cleansing required. Skin Rocks The Cream Cleanser is a fantastic conditioning cleanser that will leave skin soft and never stripped.
- Chemical Exfoliation: A good chemical exfoliant is fantastic for clearing skin buildup, decongesting pores, smoothing the skin surface and refining skin texture. Skin Rocks’ The Gentle Acid - or Control Acid for oilier skin types — are an excellent way to achieve smooth, glowing skin without any abrasion.
- Soft Washcloths/Flannels: You do not need anything abrasive on your face. Your skin is not grouting. A soft flannel or washcloth is enough manual exfoliation, especially if you have a more sensitised skin, in which case hands are are more than adequate cleansing companion. Skin Rocks’ The Flannels are soft, extra large, and bring an elevated dimension to every cleanse.
- Leave it to the Pros: There is nobody better equipped to conduct expert skin prep than a qualified facialist. Inspecting and evaluating your skin with magnifying lamps/digital skin analysis devices and years of hands-on expertise enables them to examine pores, congestion, texture, and surface concerns that aren’t obvious to you. They can develop a bespoke treatment plan for your specific skin, and help you make informed decisions about your home skincare too. This is an investment that keeps paying forward, and in the long-term will save you money on expensive products you do not need and trends that could cost you weeks, if not months, of trying to repair a sore, broken skin barrier.
