5 things I'd never do as a dermatologist⁠ ✋🏽⁠ ⁠ 1️⃣ Skip SPF on an airplane. UV exposure is stronger at 30,000 feet—even through windows.⁠ 2️⃣ Use lemon juice or baking soda on my face. These DIY hacks can seriously disrupt your skin barrier.⁠ 3️⃣ Sleep in makeup. It clogs pores, irritates skin, and accelerates aging.⁠ 4️⃣ Pick at scabs or healing pimples. That’s how you end up with dark spots and scars.⁠ 5️⃣ Use expired sunscreen. You're not getting the protection you think you are.⁠ #geetayadavmd
