Fine Lines & Wrinkles: Why They Happen and What You Can Do About It
What Really Causes Fine Lines + Wrinkles?
Let’s talk about what’s going on beneath the surface.
As we age, our skin naturally starts to lose collagen and elastin — the proteins that keep it firm, smooth, and plump. Over time, this leads to a loss of structure and the appearance of fine lines and wrinkles. But aging isn’t the only factor. Things like sun exposure, pollution, inflammation, smoking, stress, sugar, and even certain facial expressions can all speed up this process.
At a deeper level, free radical damage and glycation (caused by sugar binding to collagen) break down skin’s building blocks and lead to visible signs of aging — including sagging skin, fine lines, and deeper wrinkles.
Dynamic vs. Static Wrinkles
There are two types of wrinkles:
-
Dynamic wrinkles appear with movement — like smiling or squinting.
-
Static wrinkles stick around even when your face is at rest.
Over time, dynamic wrinkles can become static as collagen weakens and skin loses its ability to bounce back.
Wrinkle FAQs — Answered by Drea Skincare
Does dry skin cause wrinkles?
Not directly — but dry skin can make fine lines look more noticeable. Hydration matters for a smoother appearance.
Does stress cause wrinkles?
Yes. Stress increases cortisol, which can break down collagen, impair your skin barrier, and trigger inflammation.
What causes forehead wrinkles?
Forehead lines usually start from repeated expressions (like raising your brows). As collagen declines, they become more permanent.
What causes wrinkles under the eyes?
The under-eye area is delicate and thin, so it’s often the first place to show signs of aging. UV damage, squinting, and environmental stressors all play a role.
What causes crow’s feet?
These form at the corners of the eyes from smiling and squinting — then deepen as collagen and elastin break down.
Does smiling cause wrinkles?
Yes, but don’t stop smiling! Repeated expressions like smiling can leave marks over time — which is why protection and repair are key.
Does squinting cause wrinkles?
Yes. Squinting causes fine lines around the eyes that become more permanent with age. Tip: Wear sunglasses and SPF to protect the eye area.
What causes crepey skin?
Usually sun damage. Over time, UV exposure breaks down collagen and elastin, making skin appear thin, loose, and textured.
Does makeup cause wrinkles?
No, makeup itself doesn’t cause wrinkles. But it can settle into lines and highlight them — especially if skin is dry or not prepped properly.
