CHAPTER 15 – ELECTRICAL MODALITIES & EQUIPMENT (THEORY & SAFETY)

WHY THIS CHAPTER MATTERS

Electrical modalities are used in esthetics to enhance cosmetic treatments, but they also introduce additional safety considerations. Licensing examinations focus on whether an esthetician understands basic purpose, safety rules, and contraindications, not advanced technical operation.

This chapter is presented for theoretical understanding only. Estheticians must always follow state law, school policy, and manufacturer instructions when using any electrical equipment.

GENERAL ELECTRICAL SAFETY PRINCIPLES

All electrical equipment must be:

  • Used according to manufacturer instructions
  • Properly grounded
  • Kept away from water unless approved
  • Inspected regularly
  • Turned off when not in use

Electrical devices must never be used on compromised skin or clients with contraindications.

COMMON ELECTRICAL MODALITIES IN ESTHETICS

GALVANIC CURRENT

Galvanic current is a constant, direct electrical current.

Cosmetic Purpose (Theory):

  • Used to assist with deep cleansing or product penetration
  • Works with positive and negative poles

Safety Considerations:

  • Requires proper electrode placement
  • Never used on clients with contraindications
  • Must remain within cosmetic scope

HIGH FREQUENCY

High frequency uses alternating electrical current.

Cosmetic Purpose (Theory):

  • Helps dry the skin
  • Creates an antiseptic effect
  • Used after extractions in some settings

Safety Considerations:

  • Glass electrodes must be intact
  • Avoid broken skin beyond scope
  • Avoid flammable products

MICROCURRENT

Microcurrent uses very low-level electrical current.

Cosmetic Purpose (Theory):

  • Intended to tone facial muscles cosmetically
  • Used only with approved equipment

Safety Considerations:

  • Contraindicated for certain clients
  • Requires proper training
  • Must follow manufacturer instructions

LIGHT-EMITTING DIODE (LED)

LED therapy uses light energy, not electrical current passing through the body.

Cosmetic Purpose (Theory):

  • Supports skin appearance
  • Non-invasive
  • Generally low risk

Safety Considerations:

  • Eye protection may be required
  • Follow manufacturer guidelines

COMMON CONTRAINDICATIONS FOR ELECTRICAL MODALITIES

Electrical modalities must be avoided on clients with:

  • Pacemakers or implanted medical devices
  • Epilepsy or seizure disorders
  • Pregnancy (depending on modality)

  • Orange
  • Green
  • Violet

COMPLEMENTARY COLORS

Complementary colors sit opposite each other on the color wheel and are used to neutralize tones.

Examples:

  • Green neutralizes redness
  • Violet neutralizes yellow
  • Peach/orange neutralizes blue or dark circles

FOUNDATION SELECTION

Foundation should:

  • Match skin tone
  • Blend with neck and jawline
  • Be appropriate for skin type

Incorrect shade selection is a common exam scenario.

EYE MAKEUP SAFETY

Eye area skin is delicate.

Safety Rules

  • Avoid makeup on inflamed or infected eyes
  • Use disposable applicators for mascara
  • Do not apply makeup to clients with contagious eye conditions

LIP MAKEUP SAFETY

  • Use disposable lip applicators
  • Never double-dip
