Why doesn’t scar tissue tan like normal skin?
1. Scar tissue has fewer (or no) melanocytes
Even years later, scar tissue often lacks melanocytes — the cells responsible for producing pigment. Because these cells don’t fully regenerate after injury, the scar can’t tan like the surrounding skin and stays lighter in the sun.
2. Collagen in scars reflects light differently
Scar tissue is made of dense, reorganised collagen. This structure reflects light differently than normal skin, which can make scars appear lighter, whiter, or more matte — especially in the sun.
Practical takeaways
– A scar not tanning is normal, even years later
– Sun exposure won’t restore pigment — it may increase contrast
– Daily SPF helps scars mature more evenly over time and prevents further colour mismatch
– Scar texture and appearance can keep improving for 12–24 months, but pigment may never fully return
