Decoding the Delay: Understanding the Science of Post-Tanning Skin Color Change

A new study from Tel Aviv University has uncovered the science behind the delayed tanning process that occurs after sun exposure. The research reveals that the body's initial response is to prioritize repairing DNA damage in the skin cells, which inhibits the mechanism responsible for skin pigmentation. The study found that the repair mechanism takes precedence over other systems in the cell, temporarily disabling the pigmentation mechanism. Only after the DNA repair is complete does the production of melanin, which darkens the skin, begin. The findings could lead to innovative treatments for protecting the skin against radiation damage and potentially preventing skin cancer.
