8.6 Facial Machine & Device Safety and Tennessee's Legal Limits

The Two Sentences That Govern Every Device

Section 2.4 tabulates Rule 0440-02-.16 in full. Three of its clauses decide device questions, and they are worth carrying in your head as a checklist you run against any machine before you switch it on:

These clauses are routinely missed because they contradict marketing claims estheticians hear constantly. The rule outranks the supplier every time.

What (5)(a) means in practice

Any modality whose purpose or effect is to contract the muscle is an invasive procedure Tennessee prohibits an aesthetician from using. That reaches faradic and other muscle-stimulation currents, and it directly qualifies how microcurrent may be represented. Microcurrent is marketed as "muscle re-education" and a "non-surgical facelift" — language that describes exactly what the rule bans. A Tennessee esthetician must understand that applying electricity to contract facial muscles is listed among the invasive procedures prohibited by rule, and must not deliver or advertise a service on that basis.

What (6) means in practice

High frequency in an esthetics facial is used for its thermal and germicidal (ozone) effect. It may not be used to coagulate tissue, and it may not be used to remove superfluous hair, moles, warts or skin appendages. So-called "skin tag removal" or "cauterisation" devices sold to estheticians fall squarely inside this prohibition regardless of what the seller claims.

Finally, Rule 0440-02-.01(1)(d)(2) defines aesthetics to include "removal of superfluous hair by all customary means not including electrolysis." Electrolysis is outside the aesthetician scope in Tennessee.

Device-by-Device Safety and Sanitation

Facial steamer

Never leave a client unattended under a steamer.

Magnifying lamp

Rule 0440-02-.07(2)(b) requires a hands-free magnifying lamp. Position it before the client's eyes are covered, protect the eyes with damp pads, and disinfect the handle and arm between clients. The lamp is for analysis and extraction — it is not a treatment device.

Wood's lamp

A filtered black-light used in a darkened room to reveal surface and sub-surface characteristics: thickened corneum, oiliness, dehydration and pigment distribution. Two safety points that get tested: protect the client's eyes, and remember that a Wood's lamp is a visualisation aid, not a diagnostic instrument. It does not tell you a client has a disease. Anything concerning is a referral.

High-frequency unit

• Alternating (Tesla) current producing a thermal and germicidal effect through gas-filled glass electrodes; it does not contract muscle.
• Argon electrodes glow violet and are used chiefly for oily and acneic skin; neon electrodes glow orange and are used for dry or mature skin.
• Direct application places the electrode on the skin; indirect application has the client hold the electrode while the esthetician massages.
• Remove the client's metal jewellery. Never use over or near metal.
• The client should not hold the electrode while it is switched on and off — turn the unit on only after contact is established and off before breaking contact, to avoid a shock.
• Sanitation: glass electrodes are non-porous multi-use implements. Clean with soap and water and disinfect by immersion in an EPA-registered bactericidal, virucidal, fungicidal disinfectant per the manufacturer's directions — never immerse the metal shank or the handpiece. Discard any chipped or cracked electrode; a crack can cut skin and cannot be disinfected.
• Contraindications: pacemaker or implanted electronic device, metal implants in the treatment field, pregnancy, epilepsy, high blood pressure, asthma triggered by ozone, active rosacea flare, broken skin.
• Tennessee limit: no coagulation of tissue; no removal of hair, moles, warts or appendages.

Galvanic unit

• Constant direct current used for desincrustation (alkaline, negative pole, saponifying sebum) and iontophoresis (introducing water-soluble product; polarity must match the charge of the product being driven in).
• Remove metal jewellery. Contraindicated with pacemakers, metal implants, pregnancy, epilepsy, and over broken or inflamed skin.
• Braces may produce an amplified metallic taste.
• Disinfect electrodes between clients; replace worn covers.

Microdermabrasion

Mechanical exfoliation by crystal or diamond tip. Tennessee's constraint is decisive: Rule 0440-02-.16(5)(b) prohibits abrasion of the skin below the non-living, epidermal layers. Passes must remain superficial. Reduce passes over thin skin, avoid the eye orbit, never treat over active acne lesions, telangiectasia, rosacea, or recently exfoliated or lasered skin. Diamond tips and wands are multi-use and must be cleaned and disinfected between clients; crystal systems require single-use crystals with no re-use of spent crystal.

LED

Non-thermal light emitting diodes: blue for acneic skin, red for collagen stimulation and aging, amber/yellow for inflammation and redness, near-infrared for deeper tissue. No current passes through the client. Eye protection is required for both client and practitioner. Contraindicated with photosensitising medication, epilepsy or seizure disorders, active lupus, and pregnancy where the manufacturer directs. Disinfect the panel face and any contact surfaces between clients.

General Device Discipline

1. Read the manufacturer's instructions and follow them. Rule 0440-02-.17 also prohibits using any product in a manner disapproved by the FDA — off-label device use sits uncomfortably close to that line.
2. Inspect cords and housings before every use; frayed or exposed wiring takes a device out of service.
3. Keep all equipment in working order (Rule 0440-02-.07(5)(a)) and in good repair and disinfected after each service (Rule 0440-02-.13(10)).
4. Never leave a client unattended while connected to or beneath a device.
5. Screen for contraindications before every treatment, not just at the first visit.
6. Document the modality, settings, duration and client response in the record.
