What should you know about crepey skin on arms?

Arm skin may appear finely wrinkled when it has less collagen support, less moisture, or less volume beneath it. The upper arms are often exposed to sunlight, and repeated exposure can make the surface thinner-looking and more uneven. Loose skin after body-size changes may fold when the arm moves. Small rough bumps, itch, redness, or scaling suggest an additional issue such as irritation or a follicular condition rather than simple laxity.

Apply a fragrance-free moisturiser to damp skin after bathing, and use a gentle cleanser instead of hot water or abrasive scrubs. Cover the arms or use broad-spectrum sunscreen when outdoors to limit further sun-related texture change. Avoid picking rough spots. Strength training can support the muscle beneath the skin, although it does not directly remove loose skin. If the appearance remains a concern, a dermatologist can explain whether topical care, energy-based treatment, resurfacing, or surgery is relevant.

Seek an assessment for a new or rapidly changing patch, persistent itch, painful cracks, bleeding, a sore that does not heal, or a firm lump. Widespread redness, warmth, swelling, or drainage needs prompt attention. A clinician can examine the arm in good light and separate ordinary texture from dermatitis, infection, or another skin change.

Is the texture mainly dryness, sun damage, or laxity? What ingredients should I avoid? Could [Sun-Damaged Skin](/conditions/photoaging/) explain some of the change? Would [Radiofrequency Skin Tightening](/treatments/laser-and-energy/radiofrequency-skin-tightening/) be suitable for my arms? How many visits might be needed, and what aftercare would I need?
