The short pulse laser systems effectively treat the lesions by confining their energy to the melanosomes, which are the tiny granules containing melanin inside the pigment cells. The results of laser treatment depend on the depth of the melanin and the colour of the lesion and are to some degree unpredictable.
Lasers have been used successfully to treat a variety of vascular lesions including superficial vascular malformations (port-wine stains), facial telangiectases, haemangiomas, pyogenic granulomas, Kaposi sarcoma and poikiloderma of Civatte.
Melanin-specific, high energy, QS laser systems can successfully lighten or eradicate a variety of pigmented lesions. Pigmented lesions that are treatable
Properties of Laser Light
‘Laser’ is an acronym: light amplification by the stimulated emission of radiation. Lasers are sources of high-intensity light with the following properties: 1 What Types of Lasers Are there?
There are several types of lasers used in skin laser surgery What Skin Conditions Can Be Treated with Lasers?
Vascular lesions
Lasers have been used successfully to treat a variety of vascular lesions including superficial vascular Other Uses For Lasers in Dermatology
Lasers are sometimes used to remove viral warts by vaporisation (CO2 laser) or destruction of the dermal blood vessels (PDL) Laser Safety
Safety precautions will depend on which laser system is used and in what setting. They should include: 1. Thorough training of personnel 2 Adverse Effects of Laser
Laser treatments are burns. The following adverse effects may occur: 1. Temporary pain, redness, bruising, blistering and crusting 2. Infection
Transdermal drug delivery technique
Laser-assisted drug delivery (LADD) is a drug delivery technique commonly used in the dermatology field that involves lasers.
As skin acts as a protective barrier to the environment, the absorption of topical products through the epidermis is limited; thus, different drug delivery modalities have been employed to improve the efficacy of these treatments.
The use of lasers in LADD has been shown to enhance the penetration of drugs transdermal, leading to a higher absorption rate, limited systemic effects, and reduced duration of treatment.
Although this technique has evolved in the past decade due to its efficacy through scientific research and clinical practice, there remain some limitations regarding the safety aspect that needs to be taken into consideration.
