Yep, so you should look ~100 next week.That is interesting.
The sun screen agents based on titanium dioxide is interesting. Titanium dioxide is known to be a photocatalyst. It releases free radicals when radiated with uv light.
There are self cleaning tiles and paints with titanium dioxide that use this principle to be labeled anti bacterial. Just use a strong UV source and any bacteria or virus is finding itself in a predicament because the free radicals will interfere with the normal operation of the bacteira or virus being present on the tile.
Is having a skin exposed to free radicals not dangerous ?
Free radicals increase aging of cells it seems.
