Abstract :
Skin aging is a complex biological process driven by intrinsic factors, including genetic and hormonal changes, and extrinsic factors such as ultraviolet (UV) radiation, environmental pollution, and lifestyle-related stressors. These factors contribute to the degradation of structural proteins, particularly collagen and elastin, resulting in wrinkles, loss of elasticity, dryness, and uneven skin tone. Cosmeceutical actives such as retinol and peptides are widely investigated for their ability to enhance cellular turnover, stimulate collagen synthesis, and improve skin appearance. However, their clinical and cosmetic effectiveness can be limited by poor stability, low bioavailability, rapid degradation, and skin irritation. Nanotechnology-based delivery systems have therefore emerged as promising platforms for improving the performance and tolerability of anti-aging cosmeceuticals. This review critically examines the integration of nano-retinol and nano-peptide systems into advanced topical formulations, focusing on their physicochemical characteristics, skin targeting, therapeutic potential, and formulation considerations. Encapsulation of retinol in liposomes, solid lipid nanoparticles (SLNs), and nanostructured lipid carriers (NLCs) can improve photostability, controlled release, skin deposition, and tolerability while facilitating enhanced delivery across the stratum corneum and into the epidermis. Peptides are categorized according to their biological functions, including signal, carrier, and neurotransmitter-inhibitory peptides, which may promote collagen synthesis, modulate matrix metalloproteinases, reduce wrinkle formation, and support skin repair. Particular emphasis is placed on the potential synergistic combination of nano-retinol and nano-peptides within multifunctional formulations to target complementary mechanisms involved in skin aging. Key formulation parameters, including particle size, zeta potential, encapsulation efficiency, excipient compatibility, and physicochemical stability, are discussed in relation to product performance and safety. Advanced evaluation approaches, including in vitro release, ex vivo skin permeation, and clinical studies, are reviewed for assessing efficacy and skin delivery. Safety considerations, including irritation, nanotoxicological risks, and long-term exposure, are also examined. Regulatory perspectives from the US FDA, EMA, and CDSCO are discussed, along with emerging opportunities in stimuli-responsive nanocarriers, AI-assisted formulation development, and personalized nano cosmeceuticals.
