TL;DR — Quick Answer
NYLON editor review
A grip primer and setting spray serve different roles: the primer creates a tacky foundation layer that bonds makeup to skin from underneath, while setting spray seals the finished look from above. For maximum longevity, a grip primer is the more impactful step -- it prevents the root cause of makeup breakdown rather than just slowing it down.
The SHEGLAM Good Grip Hydrating Primer ($7.00, 4.96★) delivers 8-10 hours of grip hold, and the SHEGLAM HydroSlime Primer ($8.79, 4.80★) keeps foundation locked for 10+ hours with its tacky peptide-infused base. Across 4 products, the average rating is 4.87 stars.

The Love Dive functions as both a moisturizer and primer, delivering 8+ hours of hydration in a lightweight gel-cream format. About 90% of buyers with dry skin report it eliminates the need for a separate moisturizer, and around 87% say their makeup looks smoother and less dry when layered over this primer. The hydrating base prevents the dry-patch lifting that setting sprays alone cannot address.
"My dry skin was making foundation look patchy by noon no matter what setting spray I used. This primer hydrates and holds at the same time -- problem solved."
Consumer Insights
Primer vs. Setting Spray: Different Mechanisms
"Grip primers work from underneath by bonding foundation to skin, while setting sprays work from above by creating a barrier over finished makeup. Buyers who have tested both approaches consistently report that the primer step has a larger impact on overall longevity."
Grip Technology Outperforms Traditional Hold
"The tacky, adhesive-like grip created by SHEGLAM's grip primers physically bonds foundation pigment to the skin surface. Buyers describe the difference as 'foundation that is locked in' versus 'foundation that is coated over' -- and the grip approach delivers measurably longer wear."
Cost Efficiency of Primer-First Approach
"Multiple buyers report that investing in a quality grip primer ($7.00-$9.99) eliminated the need for setting spray entirely, simplifying their routine and reducing total cost. The primer does the structural work; setting spray becomes optional rather than essential."
Optimal Strategy: Both Together
"For maximum hold in challenging conditions (12+ hour wear, humid climates, oily skin), buyers who use a grip primer plus setting spray report the longest wear times. However, if choosing only one product, the grip primer consistently delivers better results than setting spray alone."
