Melanin-related disorders, such as melasma, freckles, and post-inflammatory hyperpigmentation, arise from abnormal melanin production, presenting a significant challenge in dermatology and cosmetic science. Existing treatments have limitations and potential risks, highlighting the urgent need for safer and more effective anti-melanogenic…
Skin aging is a complex process influenced by intrinsic factors like genetics and hormonal changes, and extrinsic factors like UV radiation and pollution. These factors lead to cumulative damage at the cellular and molecular levels, resulting in wrinkles, loss of…
Aging and exposure to environmental factors can cause oxidative stress and chronic inflammation in the skin, leading to disorders like dermatitis and cancer. Oleanolic acid (OA), a natural triterpenoid compound found in plants like Olea europaea, is known for its…
The increasing consumer awareness of the ecological impact of their beauty choices is driving the cosmetics industry towards sustainable, natural, and eco-friendly alternatives. Rice, particularly in Asia, is valued for its nutritional, medicinal, and skincare properties. Rice contains amino acids,…
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…
