@skindivadenise: If you just looked down and noticed more pigmentation, sun spots, or deeper lines on your left hand compared to your right, you aren't imagining things. That side window in your car blocks UVB rays (the ones that burn), but it lets UVA rays pass right through. UVA rays are the "aging" rays. They penetrate deeply, break down collagen, and trigger hyperpigmentation—and they don't care if it's cloudy or if your windows are rolled up. If you missed my last video, this is exactly why applying a high-quality broad-spectrum sunscreen to your hands before you grab the steering wheel isn't a "skincare trend"—it’s a non-negotiable step to protect your skin from daily UV damage. Drop a comment below: Did you do the test? Is your left hand showing more sun damage than your right? Let’s talk about it. Hashtags: #hands #SunDamage #UVA #matureskin #aging
