My mother has a lots of barrecos veins in legs,so she's now worrying how to put it out

There are laser treatments to get rid of varicose veins if she's willing to go that far. There are also creams to help cover them up. If they are that bad or stick out, she might consider the laser and/or other treatments available.

You can try taking vitamin C, omega fatty acid, Co Q 10 and antioxidents.
