时下,很多人都会选用祛痘类化妆品来除痘,但专家提醒,青春痘产生的原因有很多,单靠化妆品无法消除青春痘。而且按照国家对化妆品的规定,除痘类化妆品中所含有的治“痘”药物成分是很有限的,难以达到治愈的目的,长期使用一些内含防腐、抗菌成分的祛痘化妆品还可能诱发或加重痤疮。前不久卫生部对宣称“祛痘、除螨”等化妆品监督抽检结果显示,抗生素的检出率为25.4%。 相似文献

Background: Benzoyl peroxide (BP) is a first-line topical treatment in acne vulgaris (AV). However, its use can cause mild skin irritation and dryness. A new formulation of hydrogen peroxide stabilised (HPS) in monoglycerides cream (Crystacide 1%), indicated in the topical treatment of superficial skin infections, is now available as an alternative treatment.Study aim: To evaluate efficacy and local tolerability of HPS in mild-to-moderate AV in comparison with BP gel. Methods and patients: In a randomised, prospective, investigator-masked parallel-group, 8-week trial, 60 patients (24 men, 36 women, mean age 25?±?6 years) with mild-to-moderate AV, affecting mainly the face, were enrolled in the study, after their informed consent. HPS or BP (PanOxyl gel 4%) was applied topically twice daily for 8 weeks.Study outcomes: The study endpoints were: (1) Reduction in mean inflammatory (IL), non-inflammatory (NIL) and total (TL) acneic lesions in comparison with baseline; (2) Local tolerability assessed evaluating erythema, dryness and burning sensation, using a 0-3 qualitative score (score 0?=?poor tolerability; score 3?=?very good tolerability).Results: TL, NIL, and IL were assessed by an investigator unaware of treatment allocation at baseline, and week 8. The tolerability score (TS) was assessed at week 4 and 8. At baseline, the two groups were well matched for the main clinical and demographic characteristics. All patients concluded the trial. At week 0, in the HPS group TL, NIL and IL (mean?±?SD) were: 35?±?8, 20?±?6 and 16?±?7. At week 8, HPS reduced TL to 16?±?7; NIL to 9?±?3 and IL to 7?±?3 (p?<?0.001). At baseline, TL, NIL and IL, in the BP group, were 32?±?9, 24?±?8 and 18?±?7, respectively. At week 8, BP reduced TL, NIL and IL to 14?±?9; 7?±?5 and 7?±?3 (p?<?0.001). In comparison with baseline values, the percentage reductions of IL were 58% and 61% for HPS and BP, respectively (p?=?n.s.). At the end of the study the TS was 2.9?±?0.2 in HPS group and 2.4?±?0.8 in BP group (p?<?0.025). Two patients in HPS group (6%) and seven patients (23%) in BP group suffered from mild-to-moderate local erythema.Conclusions: HPS has shown to be as effective as BP in reducing both inflammatory and noninflammatory AV lesions in patients with mild-to-moderate disease. In comparison with BP 4% gel, HPS cream shows a better local tolerability profile. 相似文献

Determination of triclosan in personal health care products by liquid chromatography (HPLC) 总被引:1,自引:0,他引:1
An isocratic reversed-phase liquid chromatographic (HPLC) method is proposed for the practical and reliable determination of triclosan, an antimicrobic agent incorporated into a variety of personal heath care products. Chromatographic separations were performed on a C-18 column using acetonitrile-TEA phosphate (70 mM; pH 3.5) 55:45 (v/v) as mobile phase and UV detection at 230 and 280 nm. The selectivity of the method was assured by the on-line photodiode array detector. The identity of the triclosan peak was also confirmed by HPLC MS. The method was successfully applied to the determination of triclosan in commercially available health care products (deodorant stick, dentifrice gel, mouthrinse, toothpaste and handwash). All the products displayed triclosan concentrations in compliance with the EEC directive (< or = 0.3%,). 相似文献
