Introduction
Medically, age spots on the hands are known as seborrheic keratosis. The exact cause of age spots remains unclear, but they are associated with factors such as familial genetics, age, and gender; notably, generalized cases may follow an autosomal dominant inheritance pattern. The development of age spots is closely linked to skin aging, which varies significantly among individuals. While sun protection is routinely applied to the face, the hands are often overlooked—thereby accelerating the process of photoaging.
As women age, some develop age spots—particularly on the hands, where they often appear in large numbers. What causes age spots on the hands?
What Causes Age Spots on the Hands?
Medically, age spots on the hands are termed seborrheic keratosis. Although the exact cause remains unclear, age spots are associated with genetic predisposition, aging, and gender—especially in widespread (generalized) cases, which may follow an autosomal dominant inheritance pattern. Their appearance is closely linked to skin aging, which varies significantly among individuals.
Why are the hands especially prone to developing age spots? Aging results not only from intrinsic (internal) factors but also from extrinsic (external) ones.Approximately 80% of extrinsic aging is attributable to ultraviolet (UV) radiation—termed “photoaging”—which accelerates skin aging. The dorsal surfaces of the hands are frequently exposed to sunlight yet often neglected in daily skincare routines. While sunscreen is commonly applied to the face, the hands are frequently overlooked—thereby accelerating photoaging.
Age spots on the hands can be treated with intense pulsed light (IPL) therapy. IPL utilizes broad-spectrum light to target and fade underlying pigment deposits and seal abnormal capillaries, effectively removing age spots and resulting in smoother, more refined skin. After IPL treatment, strict sun protection is essential—opt for sunscreen application whenever outdoors. We hope this information proves helpful to you!
