Item	Group	n	0 week	4 weeks	8 weeks	12 weeks
R2 (%, gross elasticity)	Aloe sterol	23	0.823±0.029	0.835±0.037	0.837±0.035*	0.843±0.043*
	Placebo	24	0.822±0.054	0.827±0.039	0.826±0.042	0.837±0.044*
R5 (%, net elasticity)	Aloe sterol	23	0.760±0.053	0.819±0.090**	0.808±0.058**	0.826±0.076**
	Placebo	24	0.748±0.091	0.784±0.098*	0.772±0.100	0.815±0.111*
R7 (%, biological elasticity)	Aloe sterol	23	0.553±0.038	0.569±0.051*	0.568±0.046	0.575±0.060*

Notes: R2, R5, and R7 values were determined using a Cutometer on the forearm. Data are expressed as mean ± SE.

^*P<0.05,

^**P<0.005, different from week 0.

Abbreviation: SE, standard error.
