Oh, this happens to me too sometimes! I remember after a super sweaty hike last summer, I noticed these little salt crystals in my eyebrows and thought it was so weird. Turns out, it’s just from sweat. When you sweat a lot, like from working out or being in the heat, it dries and leaves behind salt, which shows up in places like your eyebrows.
It’s totally normal! Just washing your face or rinsing it with water helps, and staying hydrated can make a big difference since it keeps your sweat less salty. No worries, you’re not alone in this
