My Mom Is 48 Years Old. She Had Small Black

My mom is 48 years old. She had small black dots on her both cheeks some years back. Now from a year its spread so much. She is a vegetarian. She doesn’t eat egg as well. She is always tied up with house work. She also has a lot of grey hair. Because of the black dots and grey hair she always looks pale and tired. Anyone who looks at her asks her if her health is okay. Please suggest what can be the best treatment for her.
