Buxom has announced Ash K Holm is its new celebrity makeup artist -- calling her the "ultimate glam beauty guru."

Holm is known for larger-than-life looks, featuring bold color. Her celebrity clientelle includes Ariana Grande, Camila Cabello, Bebe Rexha, Shay Mitchell, Ashley Graham, Camila Morrone, Kim Kardashian, Khloé Kardashian, and Kris Jenner.

What's her favorite Buxom product? Buxom Full-On Plumping Lip Polish in Dolly, a mauve shimmer. 

Holm says, "I'm excited to share my love for BUXOM Cosmetics with my clients, colleagues and friends. I've kept the brand's products in my kit for years. One of my all-time favorite glosses to use on my clients is Buxom's' plumping Lip Polish in Dolly because the shimmery, mauve shade works well on everyone—including me."

The shimmery mauve hue also happens to be the brand's best-selling shade, and it can be found across multiple product categories --  gloss, lipstick, stain, lip liner, and blush. 

Holm will collaborate with the cosmetics brand to create social content, alluring campaigns, red carpet looks, and makeup tutorials that will showcase the world of Buxom to her fans and fellow makeup artists.

Jill Scalamandre, President of Buxom Cosmetics, says, "Ash is never afraid to take risks, experiment, and have fun—and that doesn't stop at the glamorous makeup looks she creates for her celebrity clients. She's fierce and fearless in everything that she does, which is what we stand for at Buxom."

Scalamandre continues, "We are thrilled to partner with such an extraordinarily talented makeup artist, and look forward to attracting new customers, as well as further engaging the always-influential makeup artist community around the world."
