The stunning actress – who is currently pregnant with her second child – says her beauty routine is very simple but it has always worked for her.
She told StyleList.com: “My mother always told me to wash my face every night, wear sunscreen during the day and drink plenty of water. It’s simple but I like to think that it works for me.
“I like sunscreen that’s not too heavy so I use my daughter’s California Baby.”
Another family trick Jessica swears by is to use her lipstick on her cheeks, saying: “Before there was cream blush, my grandmother would apply lipstick on her lips, cheeks and eyes. I still do that today.”
Jessica has previously revealed her mother used to practice her make-up applying skills on her because she was training to be a beautician.
Jessica said: “She was going to cosmetology school and she needed a model to practice on! It was for the swim team picture – full on winged eyeliner, the works.”
The 30-year-old beauty has also admitted she can put her look together in five minutes after learning to adjust her regime since becoming a mother three years ago.
She said: “My beauty regime has changed so much since becoming a mother.
“I’ve learnt to multitask and throw my look together in five minutes. I love make-up that I can apply with my finger tips, as it saves time.”
