Abstract:
Objective To study the feasibility of joint phototherapy in the treatment of post-inflammatory hyperpigmentation and non-drug therapy in clinical popularization value of 1064 nm Qswitched laser in combination with low energy intense pulsed noncoherent light for secondary pigmentation.Methods A total of 128 patients with post-inflammatory hyperpigmentation were randomly divided into 3 groups according to different treatments:first group (42 cases) was subjected to low energy 1064 nm Q-switched laser treatment;second group (40 cases) had intense pulsed light treatment;third group (46 cases) had low energy 1064 nm Q-switched laser plus intense pulsed light therapy.Results After treating for 6 times,the effective rates of intense pulsed light and Q laser were 50％ (20/40) and 52.4％ (22/42),respectively,without statistical significance between two groups (P＞0.05).Effective rate of the third group was 73.9％ (34/46),with significant difference (P＜0.05),compared with the first two groups.Conclusions For those who refuse any drug treatment,low energy 1064 nm Q-switched laser with intense pulsed light therapy is an effective option to facial postinflammatory hyperpigmentation.Furthermore,it has obvious and safe effect without complications and deserves popularization.
