The skin, the human body’s largest organ, is a crucial barrier against pathogens and environmental factors and plays significant physiological roles, including heat regulation and immune surveillance. Over 3,000 conditions can affect the skin, impacting nearly a third of the…
As global aging populations increase, understanding the histological and physiological effects of aging becomes crucial, and finding ways to counter these effects is a growing need. Skin, being the largest and most exposed organ, provides valuable insights into broader aging…
The stratum corneum (SC) serves as the skin’s primary barrier, protecting against harmful substances and minimizing water loss. Niacinamide (NIA), a form of vitamin B3, is a popular skincare ingredient known for its safety and efficacy in treating various…
The growing demand for natural and sustainable ingredients in dermatology and cosmetics has fueled the exploration of novel bio-resources. Nitric oxide (NO) plays a crucial role in skin health, participating in processes like dermal vasodilation, wound healing, immune response modulation,…
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…
