8.6 Light Therapy, Microcurrent & Arizona Device Restrictions

Light Therapy, Microcurrent & Arizona Device Restrictions

Blueprint position: Domain IV names this topic twice — at IV.C.4, inside the principles, procedures and safety of facial hair and skin care services, and again at IV.D, "apply knowledge of purpose and types of electrotherapy and light therapy." Repetition in a blueprint is a signal.

[!NOTE] Where to find the electrotherapy half. High-frequency (Tesla) current — argon and neon electrodes, direct and indirect application, effluviation — and galvanic current — the cathode, desincrustation, the anode and iontophoresis — are taught in Section 8.2, Professional Facial Treatments, Hot Towels & Massage Manipulations, alongside the massage and steam services they accompany. This section covers the light half of item IV.D, microcurrent, and the Arizona rules that decide what may lawfully be in the shop at all.

The barber link is direct: A.R.S. § 32-501(4)(f) places "providing skin care, including facials, corrective treatments, blackhead and acne removal and masks and treatment creams" inside the definition of barbering, and § 32-501(2)(a) and (9) confirm these practices may be performed "by hand or by mechanical or electrical appliances," with "electrical appliances" defined to include lasers and IPL devices as defined in § 32-516.

1. Light Therapy

Light therapy applies light energy at a chosen wavelength rather than passing a current through the tissue. It is non-thermal and non-contact in most forms, which is what distinguishes it from electrotherapy.

[!CAUTION] Eye protection is not optional under any lamp. Provide eye pads or goggles for the client and wear protection yourself. Follow the manufacturer’s stated distance and duration exactly — light therapy has no sensation to warn either of you that an exposure has run long.

2. Microcurrent

Microcurrent is an extremely low-level current that approximates the body’s own bioelectrical signals. Because the amperage is so low, the client usually feels nothing at all.

3. Universal Contraindications for Any Electrical or Light Modality

Do not apply any electrical or light modality where the client has:

• A pacemaker or any implanted electrical device
• Epilepsy or a seizure disorder
• Pregnancy
• High blood pressure or a heart condition
• Metal implants, plates or pins in the treatment area
• Open sores, broken skin, sunburn or active inflammation
• Loss of skin sensation in the treatment area
• Recent injectable treatments, laser work or a chemical peel in the area
• Photosensitising medication — this one is specific to light therapy and is easily missed; isotretinoin, some antibiotics and some diuretics all raise light sensitivity

Ask before switching anything on. Never rely on a client volunteering a medical history.

4. What Arizona Will Not Let Into the Shop (A.A.C. R4-10-112(O))

[!IMPORTANT] Arizona restricts device possession, not merely device use. Under R4-10-112(O)(1) an establishment licensee shall ensure that neither of the following is present in or used in an establishment: (a) a device, tool or chemical designed or used to pierce the dermis; and (b) a low-frequency, or low-power ultrasonic, or sonic device except one intended for skin cleansing, exfoliating or product application. The word is present — an unused device locked in a drawer still breaches the rule.

The single exception, R4-10-112(O)(2), applies where a licensee or registrant provides an invasive procedure using such a device that is otherwise allowed under Arizona law, and complies with the statutes and rules governing the procedure, training or supervision required by the relevant regulatory authorities — that is, the authorisation must come from outside the Barbering and Cosmetology Board.

Skin peeling — R4-10-112(P)

A licensee shall:

1. Remove only the non-living, uppermost layer of skin, known as the epidermis, by any method or means, and only for the purpose of beautification
2. Not use a skin removal technique or practice that affects the dermal layer of the skin
3. Not mix or combine skin removal products except as required by manufacturer instructions and approved by the FDA
4. Use only commercially available products for epidermal removal

  THE ARIZONA LINE

  EPIDERMIS  <-- a barber may remove ONLY the non-living uppermost
                 layer, and only to beautify        (R4-10-112(P)(1))
  ------------------------------------------------ THE LIMIT
  DERMIS     <-- no technique may affect this layer (R4-10-112(P)(2))
                 no device may pierce it            (R4-10-112(O)(1)(a))

Restricted tools — R4-10-112(Q)

That second entry is what governs comedone extraction in an Arizona shop: the lancet must be pre-sterilized and single-use, and its only lawful purpose is opening the follicle to release sebaceous debris.

Banned substances — R4-10-112(M)

An establishment licensee shall ensure that no products containing hazardous substances banned by the FDA for use on clients are on the premises, the rule naming liquid methyl methacrylate monomer and methylene chloride; that all products are used only in a manner approved by the FDA, EPA or other regulatory agency; and that manufacturer label instructions are followed at all times.

5. Sanitising the Equipment (A.A.C. R4-10-112(D))

Every lamp, wand, probe and handpiece in this section is electrical equipment under the Arizona rule. It must be in good repair and disinfected before each use by:

1. Removing all foreign matter
2. Cleaning and spraying or wiping with an EPA-registered bactericidal, virucidal or fungicidal disinfectant that is compatible with electrical equipment, keeping it in contact for the time specified on the disinfectant label
3. Storing the disinfected equipment in a clean place separated from its cords
4. Disinfecting any removable parts by the immersion method in subsection (B)

Goggles, eye pads and any single-use conductive pad that touches the client and cannot be disinfected are discarded immediately after use under R4-10-112(E)(1).
