Often called senile or actinic purpura, this condition is harmless despite its dramatic appearance. The name can be misleading, as it implies inevitable decline, when in fact factors such as sun exposure and medication use also play a role. These bruises typically appear on the forearms and hands and are cosmetic rather than medical concerns, rarely indicating serious disease.
How Skin Changes Lead to Bruising
Healthy blood vessels rely on collagen and elastin for support. As these proteins diminish, vessels become fragile and more prone to breaking. Thinner skin and reduced fat beneath the surface provide less cushioning, so everyday contact that once caused no harm can now result in visible bruising. Reduced elasticity also means the skin heals more slowly.
Medications and Supplements That Can Worsen Bruising
Blood-thinning medications such as aspirin, warfarin, and some anti-inflammatory drugs can increase bruising by interfering with clotting. Supplements like fish oil, ginkgo biloba, and vitamin E may have similar effects. Reviewing everything you take with your doctor is essential.
