5 lightweight, instant-absorbing sunscreen serums that are the 'hot trend' for Summer 2026.
With a hot and humid climate, many people are looking for a sunscreen that feels 'light as air' but still provides adequate protection.
Summer 2026 sees the rise of a new sun protection trend: sunscreen serums. Unlike traditional sunscreens that can clog pores or leave white streaks, sunscreen serums win over users with their lightweight texture and fast absorption, similar to a skincare essence. Not only do they protect skin from UV rays, but these products also incorporate moisturizing, antioxidant, and even anti-aging ingredients – meeting the needs of minimalist yet effective skincare. With the hot and humid climate, choosing a sunscreen that feels "light as a feather" but still provides adequate protection is what many people are looking for. Below are 5 sunscreen serums that are popular this summer.
1. Kiehl's Better Screen™ UV Serum SPF50 PA++++: Sunscreen combined with anti-aging properties.
Kiehl's products impress with their formula incorporating collagen peptides, which help improve skin elasticity. The lightweight serum texture absorbs quickly, leaving no white residue or heavy feeling on the face. In addition to broad-spectrum sun protection, the product helps skin look smoother and healthier with long-term use. This is a suitable choice for those who want to combine sun protection and skincare in one step.

It's clear that sunscreen serums aren't just a passing trend; they're gradually becoming a preferred choice for many due to their convenience and comfortable feel. With their lightweight texture, these products allow the skin to "breathe" more easily in the summer while still providing necessary protection. However, no matter how light the texture, users still need to ensure they apply enough and reapply as needed for optimal effectiveness. Combining them with other sun protection measures like wearing hats and sunglasses will also provide more comprehensive skin protection.
In the context of beauty trends increasingly leaning towards minimalism and effectiveness, sunscreen serum is the perfect solution for summer – when skin needs both protection and gentle, intelligent care.
