Gabrielle Union doesn't "mess around" when it comes to her skincare.

The actress is an avid user of sunscreen - especially when she's partaking in outdoor exercise. Gabrielle doesn't care for sun worshipping, and prefers to cover up under the harsh rays.

"I don't tan on purpose, but I do a lot of beach workouts. But I go SPF 110," she laughed to People. "I don't mess around."

Gabrielle has been a brand spokeswoman for Neutrogena since 2004 and is currently promoting their new Choose Skin Health campaign, which aims to fight skin cancer. One in five Americans will develop skin cancer in their lifetime, and the 39-year-old star doesn't want to become a statistic.

"As an African-American woman, culturally we have been told that we have natural protection against the sun - but we're absolutely part of the one in five," she explained. "As I've gotten older, I've seen relatives' moles change shape, and they think, 'That's cute - it's like Janet Jackson!' But it's not cute - it's called melanoma."

Gabrielle says her daily skincare regime is "painfully simple". The stunning star prefers to sport a natural beauty look in the day.

"I use a grapefruit cleanser because it smells good and it's got salicylic acid. If I'm having a breakout I'll use something that's acne specific, but usually it's always my clear pore astringent and my trusty sunblock," she said.

"I pop on some lip gloss and mascara and I keep it moving."

The actress regularly travels, and spends a lot of her time in hot climates. Gabrielle ensures she stays on top of her hygiene when she's jet setting.

"Water, I travel with, if I am able to - I can't take it on the plane. Also lip balm, for winter and summer because people sometimes think that when you're dehydrated a lot of sunburns can happen on your lips - lip gloss over chapped lips looks like lip gloss over chapped lips and lip stick over chapped lips is just awful," she told Beauty High.

"Oh, and mascara is a must - and deodorant! It's in my purse, I don't mess around. I'm always in a hot climate and I'm like, 'What stinks?! It's me.' No funky monkey. So now I keep deodorant in my bag."

Gabrielle has garnered a host of great beauty tips from working in the glamorous entertainment industry. However, the 39-year-old star says the simplest of secrets are often the best.

"The biggest and most inexpensive that anyone can do is water. I try to drink a gallon a day. And it's made a huge difference in my hair, skin and nails, it grows! I generally don't have major skin flare-ups because I'm so hydrated, but my hair is growing, my nails are growing, my skin is staying clear and it helps with my weight loss," she said.

"Just substituting little things out of your diet like soda, juice, any sort of sugary drink - there's no need to have flavor water when you can have regular water - just throw a little lemon in there if you want to look fancy. But that's been the best and easiest secret."
