We study the regularity of finite energy solutions to degenerate n-harmonic equations. The function K(x), which measures the degeneracy, is assumed to be subexponentially integrable, i.e. it verifies the condition exp(P(K)) ∈ Lloc1. The function P(t) is increasing on  [0,∞[  and satisfies the divergence condition

∫ 1 ∞ P(t) t 2 dt=∞.
∫ 1 ∞ P ( t ) t 2   d t = ∞ .
