The skin, serving as the primary barrier against environmental stressors, is subject to two main types of aging: intrinsic (natural) and extrinsic (photoaging). Extrinsic aging, caused by factors like pollution and UV light, accelerates skin damage by increasing reactive…
The use of preservatives in topical formulations is essential to prevent microbial growth in water-containing vehicles like creams, gels, and lotions. Ethanol (EtOH) is a common preservative known for its antimicrobial properties and solvent capabilities. However, ethanol’s impact on skin…
The increasing demand for natural and sustainable ingredients in cosmetics has driven research toward medicinal plants. Traditional medicinal plants are being reconsidered as potential solutions for aging-related skin issues, as aging causes a reduction in collagen and elastin fibers, leading…
Cracked heels aren’t just a cosmetic issue—they can be painful, uncomfortable, and, in severe cases, lead to complications. The culprit? Excessive dryness (xerosis) and thickened skin (hyperkeratosis), which cause deep fissures that make walking difficult. For individuals with diabetes, the…
The growing demand for safe, natural alternatives to conventional treatments for various skin disorders, coupled with the rise in antibiotic resistance, has increased the need for novel approaches to maintaining and improving skin health. Topical probiotics, defined as preparations containing…
The skin’s surface pH (pHss), commonly known as the “acid mantle,” plays a crucial role in maintaining skin barrier integrity, antimicrobial defense, and overall skin homeostasis. Disruptions in the pHss can lead to abnormalities in skin conditions such as eczema…
Aging, characterized by declining physical and cognitive functions, is a significant concern, spurring the exploration of anti-aging strategies. Exposure to UV radiation accelerates skin aging, causing wrinkles and loss of elasticity. Pterostilbene, a natural compound with enhanced bioavailability compared to…
The skin, which is the body’s largest organ, acts as a protective barrier against harmful substances and pathogens. Both internal and external factors influence its condition, with external factors including UV radiation, wind, humidity, air conditioning, physical damage, and microorganisms.…
Prolonged exposure to sun, particularly ultraviolet (UV) radiation, is a significant contributor to extrinsic skin aging, known as photoaging. This process manifests as dryness, wrinkles, loss of elasticity, and hyperpigmentation, resulting from structural changes in cellular components and the extracellular…
