Katie Holmes says these 5 things are the secret to achieving glowing skin (plus the skincare items she can't live without)

We all wish we could take a peek inside our favorite celebrity's bathroom to learn their beauty secrets. Well, Katie Holmes just made that dream a reality. In an interview with PEOPLE, she spilled her skincare regime, including how she achieves glowing results.

From the best foundations to the best eye creams, celebrities seem to know the best products on the market. Katie is no stranger to showing off smooth and radiant skin, which was apparent during her recent photoshoot for PEOPLE's Beautiful Issue. In it, Katie posed bare-faced without a drop of makeup. 

"I embrace my age with gratitude, and I don't worry about not having makeup on," said Katie. "My joy comes from within."

She went on to share how she keeps her skin looking (and feeling) its best through simple lifestyle habits.

"I drink a lot of water and try to eat a lot of vegetables to keep my skin as healthy as possible," she said. "I take care of my skin by cleaning it every morning and evening, [and] wearing a lot of hyaluronic [acid] serum and moisturizer."

Katie also shared that she never leaves the house without putting on sunscreen and lip gloss.

She also couldn't help but share her go-to skincare brand that she swears by. ""I am a big fan of Dr. Sturm. I regularly get [her] facials and use her products," Katie said. This isn't the first time she has talked about the skincare line, in a past interview with InStyle, Katie praised the brand sharing the exact products she loves to use.

"I also use the brand’s hyaluronic serum, brightening serum, and face cream," she told the outlet.

If you're looking to splurge during your next beauty binge, her particular favorites start at around $200. 

Katie thanked her three older sisters for teaching her how to wear makeup, but today, she prefers to keep things simple opting for a more natural look.
