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...
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...
Renewal of Skin Epidermal Stem Cells01:12

Renewal of Skin Epidermal Stem Cells

The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...

Area of Science:

  • Dermatology
  • Laser Therapy
  • Aesthetic Medicine

Background:

  • Recent advancements in dermatological laser therapy involve new wavelengths, treatment concepts, and combinations.
  • Fractional laser therapy has become a standard technique for chronic actinic damage and other skin conditions.
  • Emerging laser technologies are expanding treatment possibilities in dermatology.

Purpose of the Study:

  • To review new trends and innovations in dermatological laser therapy.
  • To highlight the applications and potential of fractional laser therapy, laser epilation, laser lipolysis, and ultra-short pulsed lasers.
  • To identify areas requiring further research, such as long-term efficacy and side effects of new laser modalities.

Main Methods:

  • Review of recent developments in dermatological laser technology and applications.
  • Discussion of fractional laser therapy for skin damage, pigmented and vascular lesions.
  • Exploration of new concepts in laser epilation (linear scanned, low fluence) and laser lipolysis.
  • Introduction of ultra-short pulsed laser systems, including femtosecond lasers, for precise ablation.

Main Results:

  • Fractional laser therapy is a safe and effective standard for chronic actinic damage, pigmented, and vascular skin changes.
  • New laser epilation systems offer faster treatment and potential for home-use devices, though long-term efficacy needs study.
  • Laser lipolysis presents a minimally invasive option for localized fat reduction with potential for liposculpture.
  • Femtosecond lasers provide precise ablation with minimal thermal damage, representing an innovation in tissue removal.

Conclusions:

  • Fractional laser therapy is established for various dermatological indications.
  • Innovations in laser epilation and lipolysis show promise but require further investigation regarding long-term effects and safety.
  • Ultra-short pulsed lasers, like femtosecond lasers, offer enhanced precision in dermatological procedures.
