Foundation haters, rejoice—Mary Phillips, the makeup artist behind Hailey Bieber, Kendall Jenner, and Priyanka Chopra’s dewy, cool-girl glam, has officially dropped her breathable, light-as-air foundation that makes you forget everything you know about traditional formulas. Bieber even trusted the silky complexion perfector for her 2026 Grammys glam. But heed my warning: it will not stay in stock for long.

The contouring powerhouse, who launched her self-abbreviated brand, M.ph, last summer with a specialized palette for her “underpainting” technique, is back with a major addition to the growing line. After creating some of Who What Wear beauty editors’ favorite sculpting and lip products (shoutout to the Overliner Lip Pencil and Lip Ciggies), Phillips has launched her very own “weightless” foundation—no really, it’s in the name—that boasts a gentle, hydrating formula, a natural finish, and the kind of medium coverage that makes people question whether you’re wearing anything at all, or just having a really good skin day. It’s available to purchase on both Sephora and the M.ph site as of right now.

Le Skin Weightless Serum Foundation
One of the first things that jumps off the page is its serum formula. Though this type of foundation is steadily increasing in popularity, with others like Victoria Beckham’s Foundation Drops and Ilia’s Super Serum Skin Tint being WWW favorites, it’s still something that grabs our attention—especially when said serum claims to have buildable coverage, which is sometimes a challenge with such lightweight, skincare-boosted formulas.
Speaking of skincare, this flexible formula—available in a whopping 35 shades that consider cool, warm, neutral, and olive undertones—is infused with 2% niacinamide and hyaluronic acid for that extra dose of nourishment. Niacinamide is a steadfast ingredient in so many people’s skincare routines, whether they realize it or not, because it treats a variety of skin concerns: redness, enlarged pores, dark spots, pigmentation… You name it. This means that in addition to the foundation’s hydrating properties, courtesy of hyaluronic acid, it can also help to even and smooth your skin tone and texture. In other words, this foundation is doing something good for your skin while you wear it, which can’t be said for all formulas.
Having sensitive and dry skin, I was relieved to see that this foundation was packed with so many beneficial ingredients—and that it was certifiably safe for irritable skin types. But to find out for ourselves, senior beauty editor Jamie Schneider and I tested this foundation for two weeks to see how it really holds up to all-day wear, cold, dry winter weather, and the mounds of other makeup products we test in a week. Keep reading to see how it fared.
The Testing Process
Application
As seen in Phillips’ TikTok tutorials, the makeup artist prefers to apply her foundation in light, sweeping motions with a fluffy brush, which helps deposit the product in a sheer fashion across her underpainted canvas. To get her exact results (minus the years of professional experience), Phillips also released a foundation brush, specially engineered with synthetic bristles to blend the formula into a natural, skin-like finish.
