The Story
M.A.C Lustreglass Sheer-Shine Lipstick in shade 544 Business Casual is a warm beige-rose with a high-shine, lightly tinted finish — the more neutral counterpart to the cult Posh Pit shade. The 3g bullet is M.A.C's standard size and is fully refillable through the Back to MAC program.
At a glance
- Best for: neutral-to-warm undertones who want a workplace-safe nude with shine
- Finish: sheer-shine, glassy look without the stickiness of gloss
- Shade family: warm beige-rose, leans warm-neutral
- Format: 3g bullet, M.A.C's classic black case
- Origin: M.A.C Cosmetics, manufactured in Canada/Italy
- Best paired with: Lustreglass 543 Posh Pit for cool-day rotation, or any liner from our M.A.C collection
Why we stock Business Casual
Business Casual is the unsung hero of the Lustreglass range. Posh Pit gets the TikTok attention, but Business Casual is the shade customers wear five days a week to the office — warm enough to flatter most skin tones, neutral enough not to compete with eye makeup. We carry it because the pair (543 + 544) covers roughly 80% of our customers' needs in one swap-by-occasion duo. All stock is imported direct with full batch traceability.
How to use
- Prep with a balm on dry days, blot, then apply directly from the bullet for a sheer wash.
- One swipe is the signature glassy look; two swipes deepen the colour without losing shine.
- Optional liner: a warm-nude liner (M.A.C's Subculture, Whirl) sharpens the edge for a more defined look. Liner is optional — Business Casual reads polished even without.
Pro tip: Business Casual layers beautifully over a deeper warm berry lipstick — it softens the underlying colour and adds the wet-look shine, making one lipstick feel like several.
Key ingredients
- Hydration: shea butter, jojoba seed oil, mango seed butter
- Plumping/shine: hyaluronic acid micro-spheres, polybutene for gloss
- Pigment: cosmetic-grade iron oxides, FD&C lakes
- Free from: parabens, mineral oil, added fragrance
Business Casual vs Posh Pit
The two top-selling Lustreglass shades, designed to cover different undertones. Business Casual (544) is a warm beige-rose — harmonises with warm and neutral skin, more "nude" in effect. Posh Pit (543) is a cool dusty mauve-pink — harmonises with cool and neutral skin, more "polished pink" in effect. If your natural lip is brown-pink, Business Casual disappears in the best way. If your natural lip is rosy, Posh Pit harmonises. Many customers own both.
FAQ
How can I verify authenticity? Check the batch code on the base of the tube against M.A.C's batch tracker. Authentic bullets have sharp, precise imprinting and the outer carton matches the code on the tube.
How long does it last on the lip? Sheer-shine finishes last 3–4 hours of comfortable wear; the pigment leaves a soft tint behind even after the shine fades.
Is it sticky like a gloss? No — the whole point of Lustreglass is visual wetness without gloss stickiness.
Will it dry out my lips? No — the shea-butter base makes it one of M.A.C's most comfortable formulas, more so than the matte and retro matte ranges.
What's the shelf life? 24 months PAO once opened, 36 months unopened from the manufacture date stamped on the base.
