Loose skin under the buttocks

The crease beneath the buttocks is shaped by skin, fat, muscle, connective tissue, and the way the upper thigh meets the buttock. Weight loss can leave a softer fold, while ageing and sun exposure can reduce skin support. Repeated rubbing, sweating, tight clothing, or prolonged sitting may cause tenderness and irritation. A new lump, marked asymmetry, or painful swelling is a different issue from gradual laxity and should be examined.

Maintain a stable routine of movement and strength work if appropriate for your health, but remember that exercise changes muscle and contour rather than removing loose skin. Reduce friction with breathable clothing and keep the crease dry if it becomes irritated. For selected mild laxity, a clinician may discuss Radiofrequency Skin Tightening or HIFU Skin Lifting. A Thread Lift has specific indications and is not a general solution for every buttock fold. Marked excess skin or a contour problem may call for a surgical opinion. Ask for an assessment of the fold, nearby nerves, scars, and sitting or activity needs.

Seek medical review if swelling appears quickly, pain is substantial, the skin becomes hot or increasingly red, or a lump persists. Urgent care is needed for fever with spreading redness, severe pain, drainage, or skin breakdown. Recurrent moisture, cracking, or itching should be diagnosed so a rash is not mistaken for cosmetic laxity.

Is the fold caused mostly by skin, fat, muscle shape, or irritation? Which treatment fits the exact area beneath the buttock? Could treatment affect sitting, exercise, or sensation? How many visits might be needed, and what recovery is expected? What would make surgery a more appropriate option?
