Background: Discoid lupus erythematosus (DLE) is restricted to the skin, mostly the face, often chronic and disfiguring. Standard medical therapies include topical corticosteroids and antimalarials. This is a retrospective long-term follow-up of refractory DLE treated with different lasers and intense pulsed light (IPL).

The longer wavelengths penetrate deeper in the dermis leading to damage of the collagen and stimulation of new collagen formation, which lead to more soft and elastic skin. Microstomia in systemic sclerosis is the end result of excessive collagen deposition, which makes the perioral skin firm and tight.

- Dermatology has seen rapid advancements over the past 20 years, primarily due to new technologies that enhance the precision of diagnosing and treating skin conditions, particularly vascular lesions.
- Modern treatment methods utilize various lasers and intense pulsed light sources that operate on the principle of selective photothermolysis, allowing for targeted therapy with minimized risks of complications.
- The selection of appropriate laser wavelengths, based on the target's absorption characteristics (like hemoglobin in blood vessels), and pulse duration is crucial for effective treatment while protecting surrounding skin tissues from damage.
Background And Objectives: Photodynamic therapy using 20% 5 aminolevulinic acid (5-ALA) has recently been introduced as a new tool in optical skin rejuvenation. The primary objective of this study was to optimize incubation time, the topical delivery mechanism (vehicle) and the concentration of 5-ALA by detecting the dynamic changes of normal skin after 5-ALA application. The secondary objective was to develop a treatment regime which minimizes post-treatment photosensitivity.

Despite the variations of length and type of hair (vellus or terminal), the growth of human hair in all body sites is cyclic. Phases of active hair growth, or anagen, are separated by periods of quiescence, or telogen. The duration of both phases varies greatly depending on the body site.

Study Design/materials And Methods: An IPL device was equipped with either a 555-950 nm filter (VL), or a 530-750 nm filter (PR).
