Learn how to properly apply silicone gel for scars with this step-by-step guide. Discover tips for best results, including product recommendations from Peach Slices.
Silicone gel has become a go-to treatment for reducing the appearance of scars, whether from acne, surgery, or injury. Unlike silicone sheets, gel formulas are transparent, dry quickly, and can be used on hard-to-reach areas or the face. But to get the best results, you need to apply it correctly. In this guide, we'll walk you through the step-by-step process of using silicone gel for scars, with tips from Peach Slices products.
Before you start, it's important to understand that silicone gel works by creating a protective barrier over the scar. This barrier hydrates the scar tissue, regulates collagen production, and protects the area from bacteria. Consistent use over weeks or months can lead to noticeable improvements in scar color, texture, and thickness.
Step 1: Clean the Scar Area
Always begin with a clean, dry scar. Wash the area with a gentle cleanser and pat dry. Avoid using any lotions, oils, or ointments before applying silicone gel, as they can interfere with the gel's ability to adhere and form a proper barrier.
For facial scars, you might want to use a mild cleanser like the Peach Slices Snail Rescue Purifying Cleanser, which is gentle enough for sensitive skin. For body scars, a simple soap and water routine works well.

Step 2: Apply a Thin Layer of Silicone Gel
Use your fingertip to apply a very thin layer of silicone gel over the scar. The gel should be just enough to cover the scar completely without being thick. A pea-sized amount is usually sufficient for a small scar. Spread it evenly in one direction to ensure full coverage.
If you are using a product like the Peach Slices Silicone Gel (if available), follow the specific instructions on the packaging. Some gels come with a spatula or applicator, but your clean finger works just as well.
- Do not rub the gel in; let it dry naturally.
- Avoid getting the gel on healthy surrounding skin if possible.
Step 3: Let the Gel Dry Completely
Allow the silicone gel to dry for about 30 seconds to a minute. You will know it's dry when it forms a transparent, tacky film over the scar. The gel should not feel sticky to the touch. If it remains sticky, you may have applied too much.
Once dry, the gel will stay in place for hours. You can apply makeup over it if needed, but wait until the gel is fully set. For best results, leave the gel on for at least 12 hours a day, though 24-hour wear is ideal.
Step 4: Reapply After Washing or Swimming
Silicone gel is water-resistant but not waterproof. If you wash the area, swim, or sweat heavily, the gel may wear off. In that case, gently remove any remaining gel with water and mild soap, pat dry, and reapply a fresh thin layer.
Consistency is key for scar treatment. Aim to use silicone gel daily for at least 3 to 6 months to see significant improvement. For older scars, results may take longer.
- Set a daily reminder to apply the gel at the same time each day.
- Keep the gel tube in a visible place, like your bathroom counter.
Step 5: Monitor Your Skin and Adjust Usage
While silicone gel is generally safe for all skin types, some people may experience irritation or breakouts. If you notice redness, itching, or new pimples, reduce usage to once a day or discontinue use. Consult a dermatologist if irritation persists.
For acne-prone skin, consider pairing silicone gel with a gentle acne treatment. For example, you can use the 3-Step Acne Starter Kit in the morning and silicone gel at night. This way, you treat active breakouts while fading old scars.

Using silicone gel for scars is a simple yet effective way to improve their appearance over time. Remember to clean the area, apply a thin layer, let it dry, and stay consistent.
