What causes crepey skin on the arms?

The skin’s deeper support network contains collagen and elastin. With time and ultraviolet exposure, this network can become less resilient, while the outer layer may hold less water. Skin then folds into fine lines and may look thin, loose, or finely wrinkled rather than simply dry.

Sun exposure is a major contributor on exposed arms, even when there has been no obvious sunburn. Repeated irritation, smoking, and changes in body volume may add to the appearance. New texture is not automatically a sign of illness, but a clinician can check whether eczema, medication effects, or another skin problem is contributing.

Use broad-spectrum sunscreen on exposed arms and reapply as directed during outdoor time. Covering the skin with clothing can add protection. Apply a rich, fragrance-free moisturiser after bathing, especially if the surface feels tight or itchy. Avoid very hot water and abrasive exfoliation, which can make fine scaling more visible.

If laxity or texture remains a concern, a dermatologist or aesthetic physician can examine skin thickness and discuss options. Radiofrequency skin tightening uses controlled heat to target deeper tissue and may be considered for selected patients; the result depends on skin quality, laxity, and treatment plan. Ask about expected changes, downtime, and risks before deciding.

Book a review for sudden widespread thinning, marked bruising, open sores, persistent inflammation, or skin changes after starting a medicine. Seek urgent care for rapidly worsening swelling, severe pain, blistering, or signs of infection. Otherwise, arrange a routine assessment if the change is progressing or affecting your comfort.

Is this mainly sun damage, dryness, laxity, or another condition? Which moisturiser and sunscreen suit my skin? Would radiofrequency be appropriate for this degree of laxity? What downtime and aftercare should I plan for?
