Does sunscreen prevent you from getting enough vitamin D?

According to Angela Jia Kim, founder and CEO of Korean-inspired Savor Beauty, much of the anti-sunscreen messaging stems from concerns about vitamin D deficiency and “the spread of misinformation online which emphasizes the natural benefits of sun exposure while downplaying the risks of skin cancer and sun damage.”

However, contrary to what WellnessTok believes, wearing sunscreen will not block absorption of vitamin D. “Many people believe sunscreen prevents adequate vitamin D production, even though studies show that it does not significantly affect vitamin D levels,” Kim explains.

Does drinking water prevent sunburn?

Some TikTok users have claimed that staying well-hydrated can prevent sunburn. This is not true.


“The idea that drinking water prevents sunburn is a myth,” says Kim. “While staying hydrated is essential for overall health, it does not protect your skin from UV damage. Proper sun protection involves using sunscreen, wearing protective clothing, and as my mom always says, walking on the shady side of the street.”

That said, there are plenty of good reasons to consider mineral sunscreen instead. “In general, using sunscreen is safe and essential for protecting your skin from harmful UV rays. However, some sunscreens contain chemicals like oxybenzone and octinoxate that may create hormonal dysregulation and negative environmental impact,” Kim explains. “Opting for mineral sunscreens with zinc oxide or titanium dioxide can minimize these risks while still providing protection.”
