What Big Bang Theory Star Melissa Rauch Looks Like Without Makeup

Melissa Rauch captivated audiences for years on "The Big Bang Theory" as Howard Wolowitz's quirky girlfriend and later wife, Bernadette Rostenkowski. Given Bernadette's esteemed profession as a microbiologist and attraction to a man with a bowl cut whose wardrobe looked like it came entirely from the Sears boy department (sorry, Howard!), she didn't exactly fit the stereotype of someone who goes shopping at Sephora and spends hours ogling over herself in the mirror. That said, one could assume that Rauch didn't wear a lot of makeup to master Bernadette's look. Well, that couldn't be further from the truth, as "The Big Bang Theory" cast looks totally unrecognizable without makeup, Rauch included. 

Onscreen, Rauch — who is still a network comedy mainstay as the star of the "Night Court" revival series — is known for her bright smile and blonde hair. However, Rauch went through a stunning transformation from a natural brunette when she was growing up into the beautiful blonde who we see today. The actor often shares barefaced photos on social media, showing fans the dialed-down version of herself that her husband Winston Rauch likely sees all the time. And if we're being honest, Rauch is so naturally stunning that the CBS makeup team likely used cosmetics to tone down her beauty to better fit her character's look.

Like the other members of "The Big Bang Theory" cast, Melissa Rauch is unrecognizable without makeup. Eternally youthful, Rauch has a flawless face when she wears no makeup, which could explain why she often chooses to go without it. On social media, she occasionally has shown fans how stunning she looks without any makeup at all. She goes makeup-free most often during the cold seasons, but can also be seen keeping it casual at home or on vacation.

In December 2024, Rauch posted a cute picture on Instagram of herself in the snow making a snowman. She sported a warm coat, a cute beanie, and no makeup! Her cheeks were pink — not from blush, but from the cold temperature. She proudly beamed over her snowman creation, captioning the photo: "Do I purposely build snowmen extra diminutive in stature, so I can smugly tower over them? You know it!"

In 2021, Rauch posted another makeup-free photo of herself on Instagram bundled up next to a snowman while inside. "When there's zero chance of snow, but the kids want to build a snowman," she wrote next to a makeshift snowman made out of a white duvet and miscellaneous art supplies. While the faux, no-melt snowman may have been the main character in that particular photo, we couldn't help but admire Rauch's raw beauty.

When it comes to the roles that Melissa Rauch has played, makeup is often used to visually illustrate the traits of her character's personality. Rauch starred as the shy, smart, and somewhat reserved Bernadette on "The Big Bang Theory." When fans first met Bernadette, she was dressed in casual preppy but girly clothes that weren't too bold – reflecting the character's shyness. Bernadette didn't wear much makeup and her eyes were often hiding behind her big glasses, overtaking her beauty from being in the spotlight. Bernadette first started out as a small recurring character but became a bit more daring and bold in her look when she emerged into a series regular.

When Rauch wrote and starred in the 2015 movie "The Bronze," she played an uptight athlete who was obsessed with winning. The character's rigid personality was reflected in her perfect mascara that made her eyes look extra alert, her cold colorless lip shade, and her symmetrical bangs and high ponytail without a single hair out of place. And now on "Night Court," Rauch brilliantly balances subdued makeup choices with menswear. She can often be seen in blazers, suits, and judge robes but still keeps femininity front and center with subtle, even makeup paints and pops of color.

While Rauch's everyday makeup for "The Big Bang Theory" wasn't over-the-top, one Halloween-themed episode saw Rauch undergo a complete style transformation. She and co-star Simon Helberg dressed up as Smurfette and Papa Smurf and their makeup team didn't take any shortcuts. During a PaleyFest panel in March 2013, Helberg and Rauch explained that it took hours to achieve Smurf status. The real struggle, however, came when it was time to shed their vibrant skin, which resulted in an awkward incident for Rauch.

As two men wiped her skin clean, she was asked to lift her legs so they could get underneath. Wearing a dress with a bodysuit underneath, Rauch obliged only to learn that her bodysuit didn't provide full coverage: "I hear one of the guys go 'Haha.' And I just thought, 'Oh, they're just telling jokes back and forth to each other.'" She took a peek in the mirror only to realize that she had inadvertently exposed herself. Rauch continued, "And I was like, 'Dear Lord Jesus, that's my business!' ... I put my legs down and then just looked at them and said, 'Long night.'"

Fans have only gotten a few brief looks at what Melissa Rauch looks like without makeup because when she is in the spotlight, she is fully glammed up! While Rauch decides to go without makeup when she is not at work, she does experiment with different looks for events and red carpets. Audiences were used to seeing Rauch wear glasses on "The Big Bang Theory." But in real life, she often chooses dark eyeliner and mascara to make a statement. The dark contrast makes her gorgeous green eyes really pop. She has also many times paired her eye makeup with flowing bangs that cover her forehead.

Her choice of lip color is notable. Sometimes Rauch opts for a neutral pink color for a minimalist look, and sometimes she'll select a bolder lip for a more pronounced look. But she always seems to go with a shade of light pink to compliment her light skin. This helps when she is wearing a darker, solid colored dress to make her entire look cohesive and assure that her pale skin and light hair does not look washed out. With any ensemble, Rauch keeps it looking classy and elegant with subtle makeup choices that bring out her raw beauty.

With her skin being so light and delicate, it's no wonder Melissa Rauch has established a comprehensive skincare routine to keep her face looking glowing and flawless. In a 2017 interview with USWeekly, Rauch named the skin care products that she can never leave home without. She mentioned how her porcelain skin can't be overlooked. "My skin is basically translucent, so I like to keep a bottle of Goddess Garden Sunblock handy so I don't turn into a tomato," Rauch said. She even posted a selfie on Instagram of herself enjoying a face mask as she rang in the New Year in 2019.

Rauch also gave readers a look into her basic makeup necessities. She revealed a few choice products that keep her face looking smooth and sweet. Her purse essentials include Jane Iredale Powder, retouching makeup from Charlotte Tilbury, and of course a beauty blender. She'll add a pink blush by Too Faced for some extra color to her face. On her lips, Rauch goes for Laura Mercier lip gloss in subtle shades, either Bare Pink or Bare Naked. And she keeps Burt's Bees Lip Balm on hand for added lip protection. As for eye makeup, Rauch's purse includes a Mac eyeliner in a slightly dark shade to offset her light skin and hair, plus LashBlast Mascara by CoverGirl.
