Why Skin Tags Appear: What Dermatologists Want You to Know
Skin tags are small, soft growths that hang from the skin, usually flesh-colored or slightly darker. While they may look odd at first, dermatologists assure that they’re very common and typically harmless. But why do they suddenly appear, sometimes seemingly overnight? The truth is, skin tags are usually the result of several everyday factors working together.
Friction and Repeated Skin Irritation
One of the most common causes of skin tags is repeated friction. When skin rubs against clothing or other skin, small growths can form over time. That’s why skin tags often appear in areas like:
Neck
Underarms
Groin
Beneath the breasts
Tighter clothing or natural skin folds can increase friction, creating the perfect environment for these tiny, soft projections to develop.
Aging and Skin Changes
Skin tags are more frequent as we age. People often start noticing them in their 40s or 50s. Over time, collagen and elastin fibers in the skin change, making the skin more sensitive to pressure and irritation. These natural shifts can make the formation of small growths more likely—a normal part of skin aging.
