Living in a humid climate like Singapore, finding the right sunscreen can be quite a challenge—it should protect effectively without feeling heavy or sticky on the skin. That’s why I was excited to try Kiehl’s Better Screen UV Serum SPF 50, especially since it is formulated with 2 million collagen peptides to not only shield but also improve skin appearance. From my experience, this sunscreen is incredibly lightweight and invisible on the skin, which means it doesn't leave that typical white cast or greasy residue that many sunscreens do. It feels almost like a serum, absorbing quickly and leaving behind a natural, glowy finish that lasts throughout the day, even in humid weather. This glow really enhances skin texture, making it look smoother and more luminous. What impressed me most was how well it worked as a makeup primer. Applying foundation over this serum resulted in a flawless finish that didn’t slide off or become patchy by the afternoon. If you have concerns about visible signs of aging or uneven skin tone, this product offers a subtle boost because the collagen peptides help improve skin elasticity and overall look with continued use. Additionally, since it offers broad-spectrum SPF 50 protection, I feel confident wearing it daily to protect my skin against sun damage, which is crucial for preventing premature aging and pigmentation. If you’re looking for a sunscreen that doubles as skincare and suits the tropical climate, I highly recommend giving Kiehl's Better Screen UV Serum a try.
