How our skin cells stay safe from sun damage
Natural protection against oxidative stress in human skin melanocytes

Skin cells called melanocytes make pigment that protects us from the sun, but this process can make harmful 'rust' inside the cells. Our body has a safety system to clean up this rust, and certain vitamins and plant chemicals might help keep it working.
Surprising Findings
UVA radiation, though less energetic than UVB, may be more insidious in causing long-term skin damage and melanoma via oxidative stress.
Most people think UVB (the burning rays) are the main threat, but UVA penetrates deeper and causes chronic oxidative damage linked to melanoma—even requiring 1000x more UVB to match mutagenic effects.
Practical Takeaways
Use skincare products containing vitamin C, vitamin E, or green tea extract to support your skin’s antioxidant defenses.

The cells in your skin that give you your color are especially at risk from sun damage and natural byproducts of pigment production, which can harm the cells and possibly lead to skin cancer or discoloration.
When skin pigment cells are under constant stress from unstable molecules, it can throw off their balance, mess up skin color, and lead to conditions like vitiligo or dark patches.
Some natural stuff like vitamins, plant chemicals, and compounds from cannabis might help protect skin cells from damage by balancing antioxidants and reducing inflammation — but we don’t have strong proof from human trials yet.
