Skin aging is a complex process driven by intrinsic and extrinsic factors that lead to the accumulation of reactive oxygen species (ROS), resulting in collagen degradation and impaired barrier function. Adenosine is a well-regarded bioactive ingredient capable of stimulating collagen…
The epidermis functions as the body’s primary shield, regulating water loss and protecting against environmental stressors through complex programs of keratinocyte differentiation and transcriptional networks. A central regulator of this biology is the Vitamin D Receptor (VDR), which modulates the…
Ultraviolet B (UVB) exposure is a primary trigger for skin damage, as it generates free radicals that induce oxidative stress and deplete endogenous antioxidant enzymes like Glutathione Peroxidase (GPx). This oxidative environment activates the Microphthalmia-associated Transcription Factor (MITF), which regulates…
The cosmetic industry is currently facing a shift driven by increasing consumer demand and stricter regulatory frameworks for sustainable, bio-based, and skin-compatible ingredients. Conventional synthetic ingredients are being scrutinized, leading researchers to explore renewable alternatives that can protect the skin…
Historically, hemp leaves (Cannabis sativa L.) have been discarded as agricultural waste because they contain lower concentrations of cannabidiol (CBD) compared to the plant’s flowers. However, the substantial biomass produced per plant presents a cost-effective opportunity for the cosmetic industry…
The human skin is a dynamic ecosystem where a balanced microbial community maintains barrier integrity and prevents pathogen colonization. However, injuries and external factors can lead to dysbiosis, an imbalance that allows opportunistic “ESKAPE” pathogens—such as Staphylococcus aureus and Pseudomonas…
Inflammation and skin wound healing represent complex biological responses essential for restoring tissue integrity; however, chronic or dysregulated inflammation can severely impede this process. Current clinical treatments often rely on synthetic pharmacotherapies like corticosteroids and non-steroidal anti-inflammatory drugs (NSAIDs), which…
The search for natural bioactive components to treat human ailments is a continuous challenge in modern medicine and dermatology. While traditional knowledge has long recognized the therapeutic properties of plants, there is a significant need for scientific validation and detailed…
Brazil faces high levels of ultraviolet radiation (UVR) exposure, posing significant public health risks; however, individuals with darker skin (phototypes IV-VI) are frequently underrepresented in photoprotection research. A common misconception that Black skin is inherently resistant to UVR damage often…
Pomegranate peel, a significant agro-industrial by-product, is rich in bioactive polyphenols like punicalagin, which offers potent antioxidant and photoprotective benefits. However, the dermal delivery of these compounds is hindered by their high molecular weight, hydrophilic nature, and susceptibility to degradation,…
