NYLON editor review
Humidity breaks down makeup by adding moisture between primer and foundation layers, causing sliding and separation. The solution is a grip primer with tacky hold technology that bonds foundation to skin even when environmental moisture is working against it.
The SHEGLAM HydroSlime Primer ($8.79, 4.80★) is specifically designed for humid conditions with its cooling jelly grip that holds foundation for 10+ hours. The SHEGLAM Good Grip Hydrating Primer ($7.00, 4.96★) delivers 8-10 hours of silicone-free grip hold. Across 5 products, the average rating is 4.85 stars.

The Blueberry + AHA variant enhances the original Good Grip's humidity resistance with added AHA exfoliation that keeps pores clear and skin texture smooth. A smoother skin surface means fewer microscopic gaps where humidity can infiltrate and separate foundation layers. The primer is 100% silicone-free and oil-free, and the AHA provides gentle daily exfoliation that improves primer adhesion over time.

The Love Dive delivers 8+ hours of hydration in a lightweight gel-cream format that does not add excess moisture in humid conditions. About 90% of buyers with dry skin report it eliminates the need for a separate moisturizer, and approximately 92% report no pore-clogging issues. The gel-cream formula absorbs quickly and creates a smooth base that resists humidity-driven breakdown, particularly for dry-to-combination skin types that still need hydration in hot weather.
"Even in Southeast Asian humidity, this primer keeps my foundation smooth and intact. The gel-cream absorbs completely so there is no extra moisture for the humidity to work against."
Consumer Insights
Humidity vs. Makeup: The Science
"Humid air adds moisture between primer and foundation layers, weakening the bond and causing foundation to slide, separate, or melt. Grip primers counter this by creating a tacky adhesive layer that physically bonds foundation to skin -- a bond that resists environmental moisture far better than traditional silicone slip."
Climate-Tested Performance
"Buyers in high-humidity regions (Florida, Texas Gulf Coast, Southeast Asia, Caribbean) consistently report that SHEGLAM grip primers hold through conditions that defeat traditional primers. The HydroSlime and Good Grip formulas receive the strongest humid-climate endorsements, with 10+ hour hold reported."
Cooling Formulas in Heat
"The HydroSlime's cooling jelly texture and the Glacier Glo's sea-mineral cooling effect are specifically cited by buyers in hot climates as providing comfort during application. Beyond the practical grip benefit, the cooling sensation makes the makeup application experience more pleasant in warm environments."
Oil-Free Advantage in Humidity
"Silicone-free and oil-free formulas perform better in humidity because they do not add a slippery layer that moisture can exploit. Buyers switching from silicone-based primers to SHEGLAM's grip technology consistently report improved humidity resistance as one of the most noticeable differences."
