Are you born with skin tags or do they develop over time?

Skin tags can develop at any age, but they are most common in adults. They are not present at birth, but rather develop over time. The exact cause of skin tags is unknown, but they are thought to be caused by a combination of factors, including genetics, hormones, and aging. Skin tags are more common in people who are overweight or obese, and they are also more common in women than in men. They are usually harmless and do not require treatment, but they can sometimes be removed for cosmetic reasons.
