Glossary
This glossary explains key terms related to LED light therapy, red light, near-infrared light, and modern skincare technology. It is designed to help you better understand how light-based treatments support healthy, radiant skin.
Light Therapy Fundamentals
LED Light Therapy
A non-invasive skincare technology that uses specific wavelengths of light to support skin renewal, repair, and overall skin health.
Red Light Therapy
A type of LED light therapy that works mainly on the upper and middle layers of the skin. It helps support collagen production and improve skin firmness and texture.
Near-Infrared Light Therapy
A deeper-penetrating form of light therapy that supports circulation, skin recovery, and calming of irritation beneath the skin’s surface.
Multi-Wavelength LED Therapy
An LED treatment approach that combines more than one light wavelength, allowing different layers of the skin to benefit at the same time.
Phototherapy
The use of light energy to support natural biological processes in the skin. It is commonly used in skincare and dermatology treatments.
Skin Structure & Cellular Processes
Collagen
A natural protein found in the skin that provides structure, firmness, and elasticity. Collagen levels naturally decrease with age.
Elastin
A skin protein that allows the skin to stretch and return to its original shape, helping maintain a smooth and youthful appearance.
Fibroblasts
Specialized skin cells responsible for producing collagen, elastin, and other supportive components of healthy skin.
Cellular Energy
The energy skin cells need to function, renew, and repair themselves. LED light therapy helps support this energy production process.
Skin Barrier
The outer protective layer of the skin that helps retain moisture and defend against environmental stressors.
Repair, Calming & Skin Health
Skin’s Natural Repair Process
The skin’s built-in ability to heal, renew, and restore itself when supported by proper circulation, nutrients, and cellular activity.
Inflammation
A natural skin response to irritation or stress. When prolonged, inflammation can slow down skin repair and collagen production.
Circulation
The movement of blood through skin tissue, delivering oxygen and nutrients needed for healthy skin function and recovery.
Sensitive Skin
Skin that reacts easily to external factors, often showing redness, discomfort, or irritation.
Post-Treatment Recovery
The period during which the skin heals and stabilizes after cosmetic or dermatological treatments.
Skincare Benefits & Use Cases
Anti-Aging Skincare
Skincare products or treatments designed to reduce visible signs of aging, such as fine lines, wrinkles, and loss of firmness.
Skin Rejuvenation
The process of improving skin appearance by supporting renewal, texture, tone, and overall vitality.
Non-Invasive Skincare
Skincare treatments that do not involve needles, surgery, or damage to the skin surface.
At-Home LED Light Therapy
LED light therapy devices designed for safe and convenient use outside of professional clinics.
Professional-Grade Skincare
High-performance skincare solutions that deliver results similar to in-clinic treatments, adapted for home use.
