Atopic dermatitis (AD) is a chronic inflammatory disease defined by inherited or acquired defects in the skin barrier, which allow for the penetration of allergens and microbes. This dysfunction triggers a type 2-skewed immune response, creating a self-sustaining pathologic cycle…
Atopic dermatitis (AD) is a chronic, multifactorial inflammatory skin disease affecting 20–30% of children, characterized by epidermal barrier dysfunction and an exaggerated immune response. A primary complication in these patients is the frequent colonization or secondary infection by Staphylococcus aureus,…
The physiological process of wound healing is a complex progression that involves three main phases: initiation, controlled development, and tissue recovery. While inflammation is an integral part of this process, excessive or prolonged (chronic) inflammation can lead to tissue damage,…
Traditional cosmetic emulsions are thermodynamically unstable systems that typically rely on synthetic surfactants to prevent degradation; however, many of these agents have low biodegradability and pose environmental risks. Pickering emulsions have emerged as a potential solution because they are stabilized…
Disorders of melanin metabolism frequently lead to pigmentation diseases, creating a significant demand for effective whitening agents. While chemical agents like hydroquinone and kojic acid exist, they are often limited by toxicity risks, poor stability, or skin irritation. Consequently, natural…
Mosquito bites are the most prevalent cause of acute itch in humans, triggering immediate reactions like wheals and erythema, followed by delayed pruritic papules. While ammonium hydroxide is a widely used over-the-counter remedy for these symptoms, its application is restricted…
Hair loss is a widespread condition that significantly impacts a patient’s mental well-being and overall quality of life. It is primarily caused by disruptions in the hair follicle cycle, often involving factors such as dihydrotestosterone (DHT) signaling, oxidative stress, and…
Oxidative stress in the skin is primarily triggered by external factors such as ultraviolet (UV) radiation, pollutants, and chemicals, as well as internal factors like stress and poor nutrition. These factors lead to the production of reactive oxygen species (ROS),…
Environmental pollution, including particulate matter, heavy metals, and ozone, is a primary driver of oxidative stress in the skin, leading to premature aging, chronic inflammation, and various dermatological pathologies. These pollutants generate reactive oxygen species (ROS) that disrupt the skin’s…
Acne vulgaris is a chronic inflammatory skin disease affecting approximately 85% of adolescents and young adults, often resulting in distressing sequelae such as scarring and postinflammatory hyperpigmentation (PIH). Because the etiology of acne is multifaceted—involving sebum production, follicular colonization by…
