Study Notes
Customer Expectations
- Cleanliness and operator education are the two primary factors customers prioritize when seeking tanning services.
Skin Overview
- Skin, the largest organ, weighs about 9 pounds and plays crucial roles in protection, temperature regulation, moisture retention, sensory reception, and chemical metabolism.
Skin Structure
- Composed of three layers: the epidermis (outer), dermis (middle), and subcutaneous (inner).
Epidermis Details
- The epidermis is the thinnest layer that produces a tan and protects the body from environmental factors.
- Divided into two sections: living and dead layers.
Layers of the Epidermis
- The horny layer consists of dead skin cells and acts as a sealant.
- The germinative layer contains living skin cells that reproduce and push older cells outward.
Types of Living Epidermis
- Three primary types of living epidermal cells: basal (parent cells at the base), keratinocytes (majority that seals the skin), and melanocytes (pigment-producing cells).
Melanocyte Function
- Melanocytes produce melanin, with about 5 million in every person, essential for skin pigmentation.
UV Light and Melanin Production
- UV light triggers melanin production, vital for tanning processes.
Fitzpatrick Skin Type System
- A questionnaire method for identifying client skin types, categorized as:
- Type 1: Extremely fair (Northern European)
- Type 2: Fair-skinned (European)
- Type 3: Central European
- Type 4: Mediterranean, Oriental, Hispanic
- Type 5: American Indian, Asian, Hispanic, African American
- Type 6: African American, Aborigine
Sunlight Composition
- Natural sunlight comprises energy waves, with various parts of the spectrum affecting skin differently.
Light Waves
- Energy waves are classified by their wavelength in nanometers, with one nanometer being one billionth of a meter.
Types of Light Reaching Earth
- Infrared light (700-30,000nm) accounts for 49% of sunlight.
- Visible light (400-700nm) represents 46% of sunlight, corresponding to the colors of the rainbow.
- UV light (200-400nm) constitutes 5% of sunlight and is divided into UVA (penetrates atmosphere) and UVB (activates melanin), while UVC does not reach Earth.
UV Light Characteristics
- UVA is linked to melanin browning and comprises 95% of summer sunlight.
- UVB, shorter in wavelength, is the burning ray that stimulates melanin production and accounts for 5% of summer sunlight.
- UVC is intense but does not emerge from tanning equipment; it serves germicidal purposes.
Protective Mechanisms
- The ozone layer acts as an invisible barrier that protects against sun radiation, being least efficient at noon.
Seasonal Sun Position
- The sun reaches its highest point in June and its lowest in December, with increased UVB exposure closer to the equator.
Radiation Types
- Radiation involves energy discharge; non-ionizing radiation is low energy, while ionizing radiation, including radioactivity, alters chemical structures.
Indoor Tanning
- Controlled mixtures of UVA and UVB are utilized in indoor tanning to provide safe and effective tanning results.
