Silicone scar tape (SST) is a medical-grade, non-invasive topical treatment used to improve the appearance of scars. The material works by providing a layer of constant occlusion and hydration to the healed scar tissue. This action regulates the production of collagen, which is often overproduced in raised scars, known as hypertrophic and keloid scars. By maintaining optimal moisture balance, the tape signals skin cells to slow down excessive collagen synthesis, resulting in a softer, flatter, and less noticeable scar over time. A common question for individuals using this therapy is how to maintain the tape’s adherence and efficacy during daily routines, particularly when showering.
Silicone Tape Adhesion and Water Resistance
Silicone scar tape is best described as water-resistant or splash-proof, rather than fully waterproof. It is designed to withstand brief exposure to moisture. The silicone adhesive layer provides sufficient tackiness to remain securely in place during a short shower. However, prolonged saturation will temporarily compromise the bond between the tape and the skin, causing the edges to lift or the entire sheet to detach.
When the tape gets wet, water can penetrate beneath the edges and interfere with the silicone’s natural adherence to the skin’s surface. This temporary loosening of the bond is normal and not an indication that the tape is permanently ruined. Because the tape is occlusive, water can become trapped beneath it, which is why exposure should be limited. For this reason, activities involving prolonged water immersion, such as swimming or taking a bath, are generally discouraged while wearing the sheet. The sheet will naturally regain its full adhesive capacity once it is completely dry.
Proper Techniques for Showering While Wearing Tape
To maximize the tape’s lifespan and maintain continuous wear time, a few simple adjustments can be made to the showering routine. The first step is to minimize the duration of the shower to limit the amount of time the tape is exposed to warm, running water. It is also helpful to keep the tape out of the direct line of the showerhead’s high-pressure spray, which can force water under the edges of the sheet.
While washing, avoid rubbing or scrubbing the area directly over the silicone tape with soap, washcloths, or sponges. This prevents dislodging the sheet or introducing residue underneath it. If the tape lifts slightly during the shower, do not attempt to press it back down until both the skin and the tape are fully dry.
The drying process is the most important step after showering. Gently pat the tape and the surrounding skin completely dry with a clean, lint-free towel, taking care not to rub the surface. Once the tape is dry, gently press down on the entire surface, particularly the edges, to ensure it has fully re-adhered to the skin.
Cleaning and Reapplication for Longevity
For reusable silicone scar tape, daily cleaning is necessary for hygiene and to restore the adhesive properties. This process should occur while the tape is removed from the skin. The sheet should be washed with a mild, non-concentrated, and fragrance-free soap using lukewarm water. Gently rub the adhesive side with clean fingertips to lift away any accumulated dead skin cells, oils, or residue that naturally build up from daily wear.
After cleaning, the tape must be thoroughly rinsed under warm running water to remove all traces of soap residue. Soap residue could otherwise interfere with the tackiness upon reapplication. To dry the sheet, lay it adhesive-side-up on a clean, dry, lint-free surface and allow it to air-dry completely before putting it back on the skin.
Never use a towel to dry the tape, as the fibers will permanently stick to the silicone’s surface, compromising its smooth application and effectiveness. When the tape is not being worn, it should be stored on its original plastic backing or in a resealable plastic container to protect the adhesive surface from dust and debris.
