Verdict: MAC's Pro Locked Brow Gel is a clear brow gel with a 12-hour flexible hold and a dual-sided brush, made with a short, five-ingredient formula. It launched in April 2024 at $24 and is $26 on MAC's site today, rated 4.5 stars from 513 reviews.
What Is in the Formula?
MAC describes a 93% naturally derived, five-ingredient formula. The ingredients its page lists are:
- Water
- Alcohol Denat.
- Acrylic Acid/VP Crosspolymer
- Aminomethyl Propanediol
- Citric Acid
Our launch post said the gel polymer technology gives hold without dryness, stiffness or stickiness.
Our take: "naturally derived" describes where the ingredients come from, not how gentle they are. The formula contains Alcohol Denat., so if you have sensitive skin around the brows, patch test first.
How Does the Brush Work?
The dual-sided brush has long and short fibers for grooming and a tapered tip for precise styling. MAC says you can get looks from "softly groomed to salon-worthy laminated looks." For a comparison with a budget clear gel, see our e.l.f. Brow Laminating Gel guide: $9, 4.6 stars from 17,271 reviews.
Who Should Buy It?
Buy it if you want a flexible, flake-free hold with a short ingredient list and a brush that can groom or style.
Skip it if you want tinted color: the gel is universal clear.
What Is Confirmed, and What Is Not?
Confirmed: price, size, claims, ingredients and rating are from MAC's product page.
Not confirmed: the "12 hours" claim, which is MAC's and which we haven't tested. The page doesn't say how MAC measured it.
September 21, 2026 update: we re-checked the price and claims. The price is $2 above the April 2024 launch price.
