Cellulite does not affect the entire arm uniformly. Its distribution follows well-defined anatomical patterns:

• Posterior upper arm (triceps region)
  → Most commonly affected area, due to vertical fibrous septa and gravitational stress.

• Lateral upper arm
  → Frequently involved, especially in patients with skin laxity and adipose tissue accumulation.

• Medial upper arm
  → Less often affected, but may show dimpling when skin flaccidity is pronounced.

• Anterior upper arm (biceps region)
  → Rarely affected; cellulite in this zone usually indicates generalized involvement or severe grades.
