The regulation of hair growth is a complex process primarily governed by the health and activity of Human Dermal Papilla Cells (HDPCs), which can be negatively impacted by inflammation and the inhibition of growth pathways. To address these issues, yeast…
In contemporary society, there is a burgeoning demand for cosmetics that are both safe and highly effective, leading to a mainstream trend of developing innovative functional products. Traditional Chinese herbal medicine has provided a rich source of bioactive monomers that…
The primary challenge in topical skin care is overcoming the stratum corneum, the skin’s outermost layer, which acts as a tightly packed lipid barrier preventing the deep penetration of active molecules. Epidermal Growth Factor (EGF) is a potent polypeptide for…
The human skin is constantly subjected to environmental stressors, such as ultraviolet radiation, leading to an unavoidable decline in biological function known as aging. A primary driver of this process is the degenerative change in tissue-specific stem cells, including the…
Aging is a complex biological process characterized by distinct morphological and physiological changes, driven by a combination of intrinsic and extrinsic factors. Recent scientific inquiry has highlighted alterations in the skin microbiota composition as a significant extrinsic factor contributing to…
The human skin serves as a vital biological barrier, with the outermost layer, the stratum corneum (SC), primarily responsible for protecting the body and regulating the absorption of external substances. While this barrier is essential for health, it presents a…
Retinol is a vital derivative of Vitamin A used extensively to treat skin pathologies such as acne, psoriasis, and photodamage due to its ability to regulate cellular proliferation and inflammation. However, its clinical efficacy is severely hampered by its low…
The skin barrier, primarily located in the stratum corneum, is the body’s first line of defense against external stressors and essential for preventing transepidermal water loss. Ceramides are the central lipid components required for the lamellar organization of this barrier;…
Psoriasis (PsO) and atopic dermatitis (AD) are the most prominent immune-mediated inflammatory skin diseases, traditionally viewed as polar opposites in their underlying pathology. While PsO is primarily driven by Th17 dysregulation, AD is characterized by a Th2 imbalance. With the…
Post-oncologic skin is characterized by significant structural and functional impairments, including delayed epidermal turnover, compromised barrier integrity, and chronic inflammation resulting from chemotherapy and radiotherapy. These treatments target rapidly dividing cells, inadvertently damaging healthy skin components and inducing mitochondrial dysfunction…
