What is DERMATOLOGY
Dermatology is a medical specialty that focuses on diagnosing, treating, and preventing diseases and conditions related to the skin, hair, nails, and mucous membranes, including:
Acne
Eczema
Psoriasis
Dermatitis
Urticaria
Fungal infections: such as athlete's foot, jock itch, etc.
Viral skin diseases: such as warts, shingles
Bacterial infections: such as cellulitis, impetigo, etc.
There are also pigmentary disorders including:
Vitiligo, Melanoma, Freckles, sun spots
What is Vascular lesions?
Telangiectases of the face, couperose, erythrosis, rosacea, neovascularizations, superficial telangiectases of the limbs, matting, port wine spots (PWS), venous lakes, nevus flammeus, senile, star-and cherry-like angiomas, varicose veins, spider veins
Spider Veins, medically known as telangiectasia, are small, thin dilated blood vessels that appear on the surface of the skin, usually in red, blue or purple reticular or dendritic patterns. They are commonly found on the legs and face, but can also appear on other parts of the body.
Laser treatment destroys dilated blood vessels through selective photothermal action. The laser energy of a specific wavelength is absorbed by the hemoglobin in the blood vessels, which is converted into heat, which heats and closes the walls of the blood vessels. Subsequently, these closed blood vessels are gradually absorbed by the body, thus eliminating or alleviating the spider veins.
About laser treatment for Acne
Laser treatment for acne (Acne) is a relatively new treatment that is primarily suitable for patients with moderate to severe acne, especially those who do not respond well to traditional treatments or who want to reduce their dependence on medications. Laser therapy works on acne lesions through different mechanisms, and the choice of laser depends on the type and severity of the acne, as well as the patient's skin type.
Dual-Wavelength Laser System (1550nm/1927nm)
1550nm
For the treatment of freckles, solar lentigines, actinic keratosis, acne scarring, surgical scarring, melasma relief, and reduction of wrinkles around the eyes.
1927nm
For the treatment of solar keratosis.
Nonablative fractional lasers (NFLs) for facial rejuvenation are mid-infrared lasers with wavelengths ranging from 1,320 to 1,940 nm that target water as a chromophore. Fractional laser treatment produces an array of microscopic treatment zones (MTZs) of thermal injury to the skin that induce a dermal wound response without damaging the epidermis.
The 1,550 nm erbium-doped laser is indicated for procedures requiring coagulation of soft tissue, skin resurfacing procedures, and treatment of dyschromia, actinic keratoses (AK), dermal pigmentary epidermal lesions (e.g., lentigines), disorders (e.g., melasma), periorbital wrinkles, acne scars, and surgical scars.
The 1,927 nm thulium laser is indicated for dermatological procedures requiring coagulation of soft tissue (Figure [X]) as well as the treatment of AK and dyschromia. The current objective is to delineate best practices for selected on-label and investigational applications of the 1,550 and 1,927 nm dual laser system, as identified by a clinical expert roundtable.
The recovery time for patients receiving general skin resurfacing can be reduced by delivering less energy in fewer passes with the 1,550 or 1,927 nm lasers, although more treatments are required over a longer timeframe. Post-treatment facial edema can be reduced by the application of cold to the treatment area and elevation of the head at night for 24 to 48 hours or until edema has completely resolved. The application of selective topical creams and serums also can help reduce patient recovery time.

The 1,550 nm erbium-doped and 1,927 nm thulium dual laser system is effective for a wide range of aesthetic and therapeutic applications, both on and off the face and across all FSTs.
Advantages of laser treatment for dermatology
- The recovery period is short and the trauma is small
- The multi-mechanism integrated treatment
Antibacterial, anti-inflammatory, and promotes healing: Lasers don't just kill acne-causing bacteria such as P. acnes; they also reduce inflammation and promote the repair and regeneration of damaged skin.
Regulates sebum secretion: Some lasers can act directly on the sebaceous glands to reduce sebum secretion, thereby controlling the occurrence of acne at the root.
- Long-term effects
- Suitable for a wide range of acne types
About Laser Therapy
In dermatology, laser therapy offers significant advantages over traditional surgery, including minimal invasiveness, precision targeting, and reduced downtime. Unlike conventional surgical methods, lasers selectively treat specific skin layers (e.g., pigmented lesions, blood vessels, or hair follicles) while sparing surrounding healthy tissue, leading to less scarring and faster healing. Additionally, laser procedures often require only topical anesthesia, minimize bleeding and infection risks, and provide superior cosmetic results with smoother skin texture and tighter collagen remodeling. Treatments like fractional laser resurfacing and vascular lasers also enable customizable approaches for diverse conditions—from acne scars to rosacea—making laser therapy a versatile, efficient, and patient-friendly alternative to traditional surgical interventions.
