Does wearing a mask actually help reduce the risk of Covid-19?

Covid-19 spreads mainly from person to person through respiratory droplets. Respiratory droplets travel into the air when you cough, sneeze, talk, shout or sing. These droplets can then land in the mouths or noses of people who are near you or they may breathe these droplets in. Masks are a simple barrier to help prevent your respiratory droplets from reaching others. Studies show that masks reduce the spray of droplets when worn over the nose and mouth. 

Wearing a mask helps protect those around you, in case you are infected but not showing symptoms, but cloth masks also offer some protection to you too. How well it protects you from breathing in the virus likely depends on the fabrics used and how your mask is made (such as the type of fabric, the number of layers of fabric, and how well the mask fits).
