Eyeshadow help!

Why do I always get these vertical lines in the inner corners of my eyelids?! Is there any tips to avoid this, or is it simply the way my eyelids are? I’m only 29 so I’m hoping it’s not an aging skin thing 😅 I’ve only applied two layers of eyeshadow. Morphe 350 Nature Glow palette (shade names Creams & Café)
