Work hard, play harder.

Molly Sims showed off her figure in a black bikini while soaking up the sun in Cabo San Lucas, Mexico, to celebrate the two-year anniversary of her cosmetics brand, YSE Beauty.

The model, 51, was all smiles on the tropical getaway as she posed for photos in SAME’s Gold Chain Triangle top ($140) and matching Gold Chain Brief bottom ($120).

Sims styled her swimwear with a black cover-up, sunglasses, a tote bag, Amanu Studio sandals and gold jewelry.

Another shot showed the actress casually lounging in a pool on a pink floatie.

“I miss my kids 😉🌴🛟,” she jokingly captioned the post via Instagram Saturday.

The Sports Illustrated Swimsuit model’s celebratory vacation at the luxe Nobu Los Cabos resort coincided with the launch of YSE Beauty’s new Like a Gloss Lip Tint Friday.

“People kept telling us how much they loved the texture, the hydration and how it made their lips look and feel amazing,” Sims told Page Six Style in an exclusive interview.

The lip tint comes in four “universally flattering” shades — pale peach, rosy taupe, warm berry and poppy red — and features skincare ingredients like hyaluronic acid, coconut oil and shea butter.

“I can’t live without a good lip moment,” Sims told us, explaining that the pigmented products make her “feel pulled together even when [she’s] bare-faced.”

YSE Beauty has earned rave reviews from Bethenny Frankel, Taylor Hill and Nicky Hilton since its launch in 2023 — and Sims teased there’s some “exciting retail news on the horizon.”

“We’re here for the Gen X woman who’s juggling a million things but still wants to feel good in her skin,” she told Page Six Style. “What’s coming next stays true to that mission.”
