Letitia Wright learnt the benefits of a good exfoliator when she needed to scrub her skin clean of dirt and dust after shooting fight scenes for 'Black Panther'.

The 24-year-old actress' skin suffered the after-effects of the fight scenes when she shot the Marvel Cinematic Universe movie - in which she plays Princess of Wakanda Shuri, T'Challa's genius scientist sister - with her skin often left clogged with dirt and dust at the end of each day.

Letitia needed to take action to keep her complexion fresh and so learned a new daily cleansing routine and she now knows that the secret to glowing skin is a "really nice" exfoliator.

Speaking to Glamour.com, she said: "The 'Black Panther' world taught me about the importance of exfoliating, I would go home and get some really nice scrubs and scrub out of the dirt and the dust that's been from a big day of fighting scenes. Sleep, water and exfoliation."

The 24-year-old British actress reprises her role in the upcoming 'Avengers: Infinity War' movie and has formed a close bond with Sebastian Stan who plays Bucky Barnes - now known as the White Wolf - in the MCU and although the 35-year-old actor advocates good sleep to stay healthy, his busy schedule means he often misses out on his required rest.

In the joint interview, Sebastian said: "Letitia would always look beautiful [on set], she's being very modest, I would tell you to go out and get sleep, obviously I'm not a good representative of that so don't look at me for that but sleep is the way to go."
