Insights

This review examines clinical evidence for light-emitting diodes (LEDs) in skin treatments. It covers photorejuvenation, acne, pigmentation, dandruff, and hair loss, focusing on device performance and supporting studies.

Area of Science:

  • Dermatology
  • Aesthetic Medicine
  • Cosmetology

Background:

  • Non-thermal, non-ablative devices, particularly light-emitting diodes (LEDs), are increasingly utilized in dermatological applications.
  • Previous reviews have established the biological effects of narrow-band visible light on skin.

Purpose of the Study:

  • To review clinical studies on the efficacy of LED devices for various skin conditions.
  • To focus on clinical proof of performance and supporting in vitro data.

Main Methods:

  • Systematic review of clinical studies.
  • Inclusion of in vitro studies supporting clinical findings.
  • Focus on non-thermal, non-ablative LED devices.

Main Results:

  • Evidence for LED efficacy in photorejuvenation and anti-aging.
  • Positive outcomes for oily or acne-prone skin treatments.
  • Potential benefits for skin pigmentation and lightening.
  • Therapeutic effects on dandruff and Malassezia-related disorders.
  • Demonstrated use in preventing and reversing hair loss.

Conclusions:

  • LED devices show significant clinical performance across a range of dermatological concerns.
  • Clinical evidence supports the use of LEDs for aesthetic and therapeutic skin applications.
  • Further research may elucidate optimal treatment protocols for specific conditions.

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Changes in Skin Color: Clinical Perspectives01:14

Changes in Skin Color: Clinical Perspectives

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Acne Infection01:27

Acne Infection

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

Pigmentation01:19

Pigmentation

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Skin Cancer01:30

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...
