Lack of melanin unironically.
White women age the worst out of everybody. It's why fillers, botox, and excessive makeup is so rampant within this group of people
Unironically latinx and indians age the worst. Whites can age fine if they apply sunscreen or stay out of the sun. Latinx and indians just look like gross toads by 30. It's partially because they get fat/skinnyfat, but aside from that they get saggy and wrinkly.
