Multiple clinical trials, systematic reviews, and meta-analyses support the conclusion that topical scar gels and silicone-based products effectively reduce, flatten, and soften the appearance of scars.
The retrieved literature contains multiple systematic reviews, meta-analyses, and randomized controlled trials specifically investigating topical scar gels (such as silicone gel). Across these studies, the evidence consistently shows that scar gels improve parameters like height, thickness, pliability, and pigmentation compared to placebos or untreated controls. There are no papers refuting the core claim, leading to a SUPPORTED verdict.
