Systemic Treatments

Medications taken orally or injected to treat more widespread skin conditions.

Histopathology

The study of changes in tissues due to disease, often using microscopic examination.

Skin Renewal Cycle

The process of skin regeneration and turnover of epidermal cells over time.

Dermal Glands

Glands located in the dermis that contribute to skin functions like sweating and lubrication.

Basement Membrane

A thin fibrous layer separating the epidermis from the dermis, facilitating nutrient exchange.

Wound Healing

A complex process involving inflammation, tissue formation, and remodeling post-injury.

Acne Scars

Residual marks left on the skin following the healing of acne lesions.

Hyperpigmentation

An increase in the pigment melanin in the skin, leading to darker areas.

Photoprotection

The protection of the skin from harmful effects of UV radiation.

Collagen Fibers

Proteins in the dermis that provide strength and structure to the skin.

Aging Skin

Changes in the skin structure and appearance that occur over time due to various factors.

Skin Elasticity

The ability of the skin to stretch and return to its original shape.

Natural Skin Barrier

The protective layer formed by the outermost skin cells that retain moisture and protect against pathogens.

Intrapersonal Communication

The internal dialogue and self-talk individuals engage in, which can affect self-perception.

Patient Education

The process of providing information and resources to patients to improve their understanding of health issues.

Cutaneous Lesions

Abnormal growths or areas of skin that can be benign or malignant.

Skin Pigmentation Disorders

Conditions that affect the color of the skin due to melanin production issues.

Cosmetic Dermatology

A branch of dermatology focused on improving skin appearance through various treatments.

UV Radiation

Ultraviolet light from the sun that can cause skin damage and increase cancer risk.

Chronic Skin Conditions

Long-term skin disorders that require ongoing management and treatment.

Skin Biopsy

A medical test that involves taking a sample of skin for examination of abnormalities.

Epidermal Growth Factors

Substances that stimulate cellular growth and proliferation in the skin.

Scarring,

A process where new tissue replaces damaged skin, often leading to changes in appearance.

Thermal Injury

Damage to the skin due to exposure to extreme heat or burn.

T-cell Mediated Response

An immune response driven by T lymphocytes that can react against body's own cells in autoimmunity.

Pigment Cells

Cells responsible for producing color in the skin, primarily melanocytes.

Pain Management

Strategies and medications used to alleviate pain during medical procedures.

Skin Analysis

Evaluation of the skin's conditions and needs for appropriate treatment.

Dermatological Care

Itching, a common symptom associated with many skin conditions.

Infection Risk

The potential for developing infections, especially in compromised skin.

Chemical Peels

A technique for improving skin appearance by applying a solution that causes the skin to exfoliate.

Skin Integrity

The condition of the skin, determining its structural and functional preservation.

Vascular Network
