May protect your skin from the sun
Dark chocolate's bioactive compounds may be beneficial to your skin as well. Flavonols have the ability to protect the skin from sun damage, improve blood flow to the skin, and increase skin density and hydration.
The minimal erythemal dose (MED) is the number of UVB rays that are required to cause skin redness 24 hours after exposure. After consuming dark chocolate high in flavonols for 12 weeks, the MED more than doubled in one study of 30 people.
If you're planning a beach vacation, consider eating more dark chocolate in the weeks and months leading up to it. However, before abandoning your normal skincare routine in favor of more dark chocolate, you should consult your doctor or dermatologist.
