Achieving makeup that stays flawless from morning to night is every beauty lover's dream. The secret lies in the prep-set-glow routine—a three-step process that primes your skin, sets your makeup, and adds a radiant finish. Whether you're heading to the office or a night out, mastering this technique ensures your look remains fresh and vibrant.

In this guide, we'll walk you through each step, highlighting essential products like the Underglaze Long-Wear PDRN Grippy Primer with Hyaluronic Acid and the Filter Fix Setting Spray. Plus, we'll share pro tips to enhance your glow without compromising longevity.
Step 1: Prep Your Canvas with the Right Primer
A good primer is the foundation of long-lasting makeup. It creates a smooth base, minimizes pores, and helps your makeup adhere better. For a grippy, hydrating option, the Underglaze Long-Wear PDRN Grippy Primer with Hyaluronic Acid is a game-changer. Its PDRN complex and hyaluronic acid lock in moisture while providing a tacky surface that holds foundation and concealer in place for hours.
Apply a pea-sized amount to clean, moisturized skin, focusing on the T-zone and areas where makeup tends to fade. Let it set for a minute before moving to the next step. This primer works wonders under any foundation, ensuring your base stays put even in humid conditions.
- Use a primer suited to your skin type: hydrating for dry skin, mattifying for oily skin.
- Allow primer to fully absorb before applying foundation to avoid pilling.
Step 2: Set It and Forget It with a Setting Spray
Setting spray is the unsung hero of long-lasting makeup. A few spritzes can lock in your look, prevent fading, and even help melt powders into the skin for a natural finish. The Filter Fix Setting Spray is a cult favorite for its fine mist and long-wear formula. It not only sets makeup but also blurs imperfections and controls shine.
Hold the bottle about 8 inches from your face and mist in an X and T pattern. Allow it to dry naturally—don't fan or touch your face. For extra staying power, apply a layer between each makeup step: after primer, after foundation, and after finishing powders.
- For a dewy finish, choose a setting spray with illuminating properties.
- Carry a mini setting spray like the Mini Prep-Set-Glow for touch-ups on the go.
Step 3: Glow Without the Grease
The 'glow' step is all about adding a luminous, healthy radiance without compromising longevity. Liquid highlighters, illuminating powders, and glow-boosting mists are your best friends. The Radiance Booster is a versatile product that can be mixed with foundation for an all-over glow or dabbed on high points like cheekbones and brow bones.
Apply glow products sparingly and build up as needed. For a subtle sheen, use a damp beauty sponge to press the product into the skin. Avoid applying glow products over areas that get oily quickly, such as the nose and forehead. Instead, focus on the cheeks and cupid's bow for a natural lift.
- Layer cream and powder highlighters for a multidimensional glow that lasts.
- Use a setting spray with shimmer particles for an all-over luminous finish.
Pro Tips for All-Day Wear
Beyond the three steps, a few extra tricks can make your makeup last even longer. Always start with a clean, moisturized face—hydration is key for makeup adherence. Use a mattifying primer on oily zones and a hydrating one on dry areas. Blotting papers are great for midday shine without disturbing your makeup.
Consider using a long-wear foundation and setting powder to lock everything in. The Radiant Concealer & Brightening Duo is perfect for touch-ups under the eyes and on blemishes without caking. And don't forget to prep your lips with a lip balm before applying lip products for a smooth, lasting color.
- Set your undereye concealer with a translucent powder to prevent creasing.
- Carry a mini setting spray for refreshing your makeup throughout the day.
Mastering the prep-set-glow routine is your ticket to makeup that lasts all day and looks radiant. Start with a primer like the Underglaze Long-Wear PDRN Grippy Primer, lock it in with the Filter Fix Setting Spray, and add a touch of glow with the Radiance Booster.
