What Is One Size Secure the Sweat Primer?
The One Size Secure the Sweat Primer is a mattifying, sweat-resistant primer designed to keep makeup intact for extended hours, even in challenging conditions. Developed by the beauty brand One Size, founded by makeup artist and influencer Patrick Starrr, this primer caters to people who need their makeup to endure heat, humidity, and physical activity. It’s part of a new generation of primers formulated not only to smooth the skin but also to actively resist sweat and shine. Unlike many mattifying primers that feel dry or tight, Secure the Sweat is made to be lightweight and flexible on the skin.
Main Purpose of the Product
The key purpose of this primer is to create a sweat-proof barrier between your skin and your makeup. It helps control oil, minimizes shine, and ensures that foundation and concealer stay in place throughout the day. Whether you’re performing on stage, attending a long event, or just running errands on a hot day, this primer works to prevent makeup from melting or fading due to perspiration.
Key Features and Benefits
One Size Secure the Sweat Primer offers a combination of advanced skincare and makeup technology, making it ideal for anyone with an active lifestyle or oily skin. Its formulation delivers both performance and comfort, making it suitable for daily wear as well as high-pressure situations.

The blend of sweat control and skin comfort makes it unique compared to traditional mattifying primers, which often prioritize oil absorption at the expense of hydration.
How It Works
At its core, the One Size Secure the Sweat Primer uses a film-forming technology that adheres lightly to the skin, creating a breathable barrier. This barrier locks makeup in place while allowing natural skin movement and flexibility. The formula reacts to moisture by tightening slightly, preventing sweat from disrupting foundation or concealer. It also helps balance sebum production throughout the day, keeping the complexion matte without looking flat or dry.
Science Behind the Sweat Resistance
Unlike traditional silicone-based primers that only sit on the skin’s surface, this primer forms a semi-permeable layer that adapts to moisture levels. When your body temperature rises, it helps resist perspiration by redirecting sweat away from the makeup layer. This mechanism ensures that foundation doesn’t break apart or turn patchy, maintaining a consistent, polished look even in high humidity or during physical activity.
Ingredients Overview
The formula is built on a combination of mattifying agents, skin-smoothing silicones, and moisture-balancing components. While the exact proprietary blend remains unique to the brand, several key ingredients contribute to its performance and comfort.
- SilicaHelps absorb excess oil and create a soft-focus finish that minimizes texture.
- Film-forming PolymersCreate the sweat-resistant barrier that locks makeup in place.
- NiacinamideKnown for balancing oil production and improving skin texture over time.
- GlycerinAdds hydration and keeps the skin comfortable, preventing dryness or cracking.
- DimethiconeSmooths the skin’s surface and blurs fine lines for a flawless foundation application.
This combination results in a product that doesn’t just perform cosmetically but also supports skin health with continued use. The primer is designed to suit a wide range of skin types, though it performs exceptionally well on combination and oily skin.
How to Use One Size Secure the Sweat Primer
Using the primer correctly maximizes its sweat-resistant properties and ensures your makeup lasts all day. Application technique can make a noticeable difference in results.
Application Steps
- Start with clean, moisturized skin. Ensure your skincare has fully absorbed before applying primer.
- Dispense a small amount of primer a pea-sized drop is usually enough for the entire face.
- Warm the product slightly between your fingers and press it onto areas prone to oil or sweat, such as the T-zone, forehead, and upper lip.
