My arm skin bruises and tears so easily now. What changed?

Furthermore, the skin’s ability to repair itself slows with age. The turnover rate of skin cells and the healing process can take twice as long in older adults compared to when they were younger. This slower repair process means that minor injuries can take longer to heal and are more noticeable.

Chronic sun exposure is a significant contributor to skin thinning, particularly on the forearms, which are often exposed to sunlight. Ultraviolet (UV) radiation breaks down collagen and elastin fibers, accelerating the thinning process.

This damage manifests as ‘paper-thin’ skin, which is more vulnerable to tears and bruises. The cumulative effect of sun exposure over the years can lead to significant changes in skin texture and resilience.

Certain medications can increase the likelihood of bruising and skin tearing. For example, corticosteroids, commonly prescribed for inflammatory conditions, can lead to skin thinning as a side effect.
