Prosthetic liners are commonly manufactured from silicone, thermoplastic elastomer (TPE/gel), or urethane, each offering distinct advantages and challenges for skin health. Silicone liners are generally more durable, resistant to stretching, and provide excellent suspension, but they can create higher friction and shear forces against the skin if the socket fit is suboptimal, potentially contributing to skin breakdown, blistering, or irritation in sensitive individuals. Gel (TPE) liners are softer and more compliant, often providing greater cushioning and comfort for patients with bony prominences or fragile skin; however, they may allow increased movement within the socket, resulting in repetitive shearing forces that can damage underlying tissues over time. Urethane liners excel at distributing pressure and reducing localized stress but may be less durable and can be more difficult to don and doff. Regardless of liner material, proper daily cleaning is essential to maintain skin integrity. The use of harsh soaps, alcohol-based cleansers, antibacterial detergents, or other aggressive cleaning agents can strip natural skin oils, alter skin pH, and leave residues on the liner surface, leading to dryness, cracking, dermatitis, and increased susceptibility to friction-related injury. Mild, fragrance-free soaps are generally recommended to clean both the residual limb and liner while preserving skin health and liner performance.
