You can help them fade. Sunscreen is a scar’s worst enemy (in a good way). UV rays darken scar tissue, making it stand out. Slap on SPF 50 and your scar stays pale and shy.
Silicone sheets and gels? They work a bit—by keeping the scar moist and compressing the collagen. But it’s like putting a band-aid on a cinder block. Temporary improvement, not a miracle.
