Psych Star Sarah Shahi, 43, Shares Swimsuit Photo Looking "Sublime"

Psych star Sarah Shahi is a big fan of skincare products, and likes to share her tips with fans and followers. Shahi, 43, shared pictures of herself wearing a blue bikini and straw hat, showing off her beautiful skin—with a focus on her lips. "@clarinsusa lip oils. Sweet not sticky. 💋," she captioned the post. "Sublime," a fan commented. Shahi is not afraid to bare it all on screen—here's how she takes care of her health and beauty.

Shahi is very interested in astrology. "I'm a Capricorn, and I've really gotten into my [full chart]," she says. "The other cool thing about my ancestry that I didn't know until recently is, as a culture, we're very attached to the stars. The followers of the first religion in Iran were sun worshippers. I often realize how small I am in relation to everything in the world—and how connected I am at the same time. That feeling creates a sense of, 'Wow, you have to let go of things, and you have to trust there is some kind of world order, and just go with the flow.' At the end of the day, as long as you can look in the mirror and be happy with what you see, the rest is out of your control."

Shahi isn't afraid to spend money on her skin. "I'm big on lasers and anything that is 'upkeep.' The Merit brand has the most luxurious lip stains and lipsticks," she says. "I just now saw that they have a skin-care line that's coming out. I am a huge fan of that line. I will absolutely have to hit them up for that! I'm also a big fan of Shani Darden. She has this lactic acid product and, anytime I wear it, people are like, 'Your skin looks like glass.' I'm big on skin care, that's for sure—it's my one splurge. What else? I love those wipes [from] Dr. Dennis Gross. The peels! They are excellent. And Sol De Janeiro's body creams are like crack. They smell so good."

Shahi loves to read and write. "There are two books I'm reading right now; I always have a couple going," she says. "One of them is called It Ends With Us by Colleen Hoover—I'm also reading something called The Betty Body [by Dr. Stephanie Estima]. When you hit your 40s, women's bodies change. That's something I've been on a journey to try to figure out: what my body needs right now. I'm also in the process of writing a book!"

Shahi says there were parts of Sex/Life where she didn't look "perfect" and is glad. "There are scenes where you can see my stomach doesn't look 100%, it doesn't look great, and I'm proud of it," she says. "I never quite realized the power of my body until I had children, until I breastfed all my children. Now, I'm proud. I'm supremely proud of every stretch mark or curve or bump or whatever it is; I earned those. I really do live by the whole 40 is the new 20, because I was so insecure about the way I looked when I was in my twenties."

Shahi is deeply appreciative of the wisdom that comes with age. "There was a big freedom that happened when I turned 40," she says. "I was just like, 'here I am, the good, the bad, the ugly, the insecure. I'm not going to make apologies for it and I'm going to put it out there.' I wouldn't trade that moment for any part of my 30s, any part of my 20s; it's a privilege to grow older and it's a privilege to carry wisdom with you. One of the things I've always said is, 'I don't claim to know much, but I do know more than I did last year.'"
