Trip to Hundred Islands In the summer of my third grade, when I was eight years old, I remembered when my parents told me that we were going to take a trip to Hundred Islands National Park in Pangasinan, Philippines.

Depigmentation evolved to allow vitamin D3 synthesis outside tropical regions away from the equator. Depigmentation is the lightening of the skin to permit higher synthesis of vitamin D3. There is a requirement of vitamin D3 in low…
