V. DEFINITIONS Acne Vulgaris: Is the formation of comedones, papules, pustules, nodules, and/or cysts as a result of obstruction and inflammation of pilosebaceous units (hair follicles and their accompanying sebaceous gland). Diagnosis is made by examination and treatment is based on severity which can involve a variety of topical and systemic agents directed at reducing sebum production, comedone formation, inflammation, and bacterial counts and at normalizing keratinization (Keri, 2020).

Actinic Keratosis: Also known as AKs or solar keratosis) typically occurs on the face, lips, ears, bald scalp, shoulders, neck and back of the hands and forearms. The size ranges from a tiny spot to as much as an inch in diameter, actinic keratosis usually appear as small crusty or scaly bumps or “horns.” The base can be dark or light skin-colored and may have additional colors such as tan, pink, and red (The Skin Cancer Foundation, 2021).

Chemical Peel: Is a procedure in which a topically applied wounding agent creates smooth, rejuvenated skin by way of a wound repair process, collagen remodeling and exfoliation. This procedure is usually performed on the face. It allows a new layer of skin regeneration (Berman, 2021).

Dermabrasion: Involves the use of tools (e.g., high-speed brush, diamond cylinder, fraise or silicon carbide sandpaper) to remove the epidermis or epidermis and part of the dermis. One advantage of the procedure is that it allows the clinician to etch scar edges precisely without thermal injury. In addition, dermabrasion procedure requires meticulous intraoperative assistance, and has the potential for postoperative scarring, dyspigmentation, and milia formation (Saedi, 2020).

Home Phototherapy: A narrowband ultraviolet B (NB-UVB) therapy conducted in a home setting and typically considered appropriate for patients with photoresponsive skin conditions who have access barriers (scheduling, transportation, cost, etc.) to outpatient treatment (Ontario, 2020).

Psoriasis Area and Severity Index (PASI): A measure of overall psoriasis severity and coverage. It is a commonly-used measure in clinical trials for psoriasis treatments. PASI consists of two steps, calculating the BSA (Body Surface Area) covered with lesions and assessment of the severity of lesions. The assessment of lesion severity includes the lesions' erythema, induration, and scaling. All calculations are combined into a single score (PASI Score) in the range of 0 (no psoriasis on the body) and up to 72 (the most severe case of psoriasis). Typically, the PASI would be calculated before, during and after a treatment period in order to determine how well psoriasis responds to the treatment (Das, 2020).

Photodynamic Therapy: (PDT) is a noninvasive, nonscarring treatment most frequently used for the treatment of nonmelanoma skin cancer and precancerous lesions. It is a two-step treatment where a light-sensitizing topical agent is applied to the lesions, followed by illumination with visible light to activate the drug and destroy the target tissue. PDT was developed primarily for the treatment of cancer and precancers (Maytin , 2021) .

Phototherapy: Or light therapy, involves exposing the skin to ultraviolet light on a regular basis and under medical supervision. Treatments are done in a doctor's office or psoriasis clinic or at home with phototherapy unit (National Psoriasis Foundation, 1996-2021a).

Port-wine Stain: Is a birthmark in which swollen blood vessels create a reddish-purplish discoloration of the skin. It is caused by an abnormal formation of tiny blood vessels in the skin. In rare cases, port-wine stains are a sign of Sturge-Weber Syndrome or Klippel-Trenaunay-Weber Syndrome (U.S. National Library of Medicine, 2019a).

Psoriasis: Is an inflammatory disease that manifests most commonly as well-circumscribed, erythematous papules and plaques covered with silvery scales. Multiple factors contribute, including genetics. Common triggers include trauma, infection, and certain drugs. Symptoms are usually minimal, but mild to severe itching may occur (Das, 2020).

1. Plaque Psoriasis: Is the most common form of the disease and appears as raised, red patches covered with a silvery white buildup of dead skin cells or scale. These patches or plaques most often appear on the scalp, knees, elbows and lower back. They are often itchy and painful, and they can crack and bleed (National Psoriasis Foundation, 1996-2021b). 2. Guttate: Is a form of psoriasis that often starts in childhood or young adulthood and often develops suddenly. It usually appears after an infection, most notably strep throat caused by group A streptococcus (National Psoriasis Foundation, 1996-2021b). 3. Inverse Psoriasis: Is characterized by skin redness and irritation and occurs in the armpits, groin and in between overlapping skin rather than the elbows and knees (National Psoriasis Foundation, 1996-2021b). 4. Pustular Psoriasis: Is characterized by white pustules (blisters of noninfectious pus consisting of white blood cells) surrounded by red skin. It is not an infection, nor is it contagious. It may appear only on certain areas of the body, such as the hands and feet or it may cover most of the body (National Psoriasis Foundation, 1996-2021b). 5. Erythrodermic Psoriasis: Is a rare type of psoriasis, affecting about 2 percent of people living with psoriasis. It can cause intense redness and shedding of skin layers in large sheets. It often affects the whole body and can be life-threatening. Symptoms include severe itching, pain, changes in heart rate and temperature, dehydration and nail changes (National Psoriasis Foundation, 1996-2021b).

PUVA: Is a combination of psoralen (P) and long-wave ultraviolet radiation (UVA) that is used to treat psoriasis and some other severe skin conditions. Psoralen is a medication taken by mouth that makes the skin disease more sensitive to ultraviolet light. This allows the deeply penetrating UVA band of light to work on the skin (American Osteopathic College of Dermatology, 2019).

Ultraviolet light B (UVB): Is an effective treatment for psoriasis. UVB penetrates the skin and slows the growth of affected skin cells. Treatment involves exposing the skin to an artificial UVB light source for a set length of time on a regular schedule. This treatment is administered in a medical setting or at home. There are two types of UVB treatment, broad band and narrowband. Narrow-band UVB light bulbs release a smaller range of ultraviolet light, narrow-band UVB may clear psoriasis faster and produce longer remissions, and narrow-band UVB may require fewer treatments per week. UVB treatment is offered in different ways which include small units for localized areas such as hands and feet, full-body units, or hand-held units. Some UVB units use traditional UV lamps or bulbs and others use LED bulbs (National Psoriasis Foundation, 1996-2021c).

Vitiligo: Causes white patches on your skin. It can also affect your eyes, mouth, and nose. It occurs when the cells that give your skin its color are destroyed. The reason for the cells being destroyed are not known. It is more common in people with autoimmune diseases, and it might run in families. It usually starts before age 40. The white patches are more common where your skin is exposed to the sun and in some cases, the patches spread. Vitiligo may cause hair loss to premature graying Treatments for vitiligo include medicines, light therapy, and surgery (U.S. National Library of Medicine, 2019b).

VI. BACKGROUND Numerous types of laser treatments are available to help treat a variety of skin conditions. Laser treatment, or phototherapy, is most commonly used in patients with psoriasis. Psoriasis is a chronic, recurrent, and immune-mediated inflammatory disease that affects 2-3% of the world population and is associated with genetic predisposition, autoimmune disorders, psychiatry and psychological health, and environmental factors such as infection, stress, trauma (Zhang, 2018).

There are several types of psoriasis: plaque, guttate, inverse, pustular, erythrodermic, nail, and psoriatic arthritis(American Academy of Dermatology Association, 2021b). Plaque psoriasis is present in the majority of patients that experience symptoms. Initial treatment options for the first several months often include various types of creams and ointments. Other treatment options include oral and biologic prescription drugs. For more severe cases of psoriasis, where creams and ointments are not sufficient, light therapy/ phototherapy is recommended (Feldman, 2021).

Phototherapy is a common form of treatment in patients with severe psoriasis. It is most effective when used in conjunction with prescribed creams and ointments. Dermatologists consider several types of phototherapy when treating patients. For patients with light to mild psoriasis, simply getting additional exposure to natural sunlight can help improve symptoms. More severe cases of psoriasis typically undergo Ultraviolet B (UVB) therapy or Psoralen plus Ultraviolet A (PUVA) therapy (Wong, 2013).

Acne is an inflammatory disorder of the skin, which has sebaceous (oil) glands that connects to the hair follicle, which contains a fine hair. In healthy skin, the sebaceous glands make sebum that empties onto the skin surface through the pore, which is an opening in the follicle. Keratinocytes, a type of skin cell, line the follicle. In a normal process as the body sheds skin cells, the keratinocytes rise to the surface of the skin. In acne, the hair, sebum, and keratinocytes coalesce inside the pore which prevents the keratinocytes from shedding and keeps the sebum from reaching the surface of the skin. The mixture of oil and cells allows bacteria that normally live on the skin to grow in the plugged follicles and cause inflammation which is swelling, redness, heat and pain. When the wall of the plugged follicle breaks down, it spills the bacteria, skin cells, and sebum into nearby skin, creating lesions or pimples (NIAMS, 2020).

Actinic keratosis (AKs) are common cutaneous lesions that result from the increase of atypical epidermal keratinocytes. Major risk factors for their development include chronic sun exposure, fair skin, advancing age and male sex. Actinic keratosis may progress to squamous cell carcinoma (SCC) and approximately 60% of cutaneous squamous cell carcinomas (cSCCs) arise in sites of preexisting actinic keratosis. Biopsy is indicated if the diagnosis is uncertain; a common indication for biopsy is distinguishing actinic keratosis from squamous cell carcinomas (Padilla, 2021).
