This study investigates the effects of aroma neck and shoulder massage and Red LED irradiation on cutaneous microcirculation in the neck area. In this study, 30 women aged 20 to 60 were randomly assigned to three experimental groups. Group A (n=10) received Red LED irradiation after aroma neck and shoulder massage, while Group B (n=10) rested for 15 minutes after aroma neck and shoulder massage. Group C (n=10) only received Red LED irradiation. The results showed significant main effects of time between the baseline and post-treatment measurements in Groups A and B (F = 29.883, p < 0.001, 𝜂² = 0.624), however, the main effects of the groups were not significant (F = 0.202, p = 0.659, 𝜂² = 0.011), but there was a significant interaction between group and time (F = 8.452, p = 0.001, 𝜂² = 0.320). There were no significant statistical differences in cutaneous microcirculation in the neck area after treatment in Group C (p > 0.05, Cohen's d = 0.202). In conclusion, Red LED treatment demonstrates limited effects on cutaneous microcirculation in the neck area, differentiating with the results of Groups A and B. Specifically, the combined effect of aroma neck and shoulder massage and Red LED treatment in Group A was not significant.
