Lubricants, such as silicone gel sheets and ointments, are used in the management of scars and scar tissue with a moderate degree of scientific support. Clinical studies have shown that topical silicone-based products can improve the appearance, texture, and elasticity of hypertrophic and keloid scars. Silicone gel sheets and gels are thought to work by hydrating the scar tissue, modulating fibroblast production, and reducing collagen deposition. These mechanisms help flatten and soften scars over time. Several randomized controlled trials and meta-analyses support the use of silicone products for scar management, particularly in reducing scar height, redness, and hardness.

Other lubricants such as petroleum jelly (petrolatum) are commonly recommended to keep healing wounds and scars moist, which may prevent excessive scab formation and help optimize the wound healing environment. Moist wound healing, facilitated by such lubricants, is supported by evidence showing improved epithelialization and reduced scar formation compared to dry healing. However, the evidence supporting the use of non-silicone lubricants specifically for scar remodeling is less robust than that for silicone products.

In summary, there is moderate scientific evidence supporting the use of certain lubricants—especially silicone-based formulations—in the treatment and improvement of scars and scar tissue. Their use is recommended by clinical guidelines and supported by controlled studies, though the degree of benefit varies by individual and scar type.
