Laser toning with low fluence Q-switched 1,064 nm Nd:YAG laser for skin rejuvenation and melasma can be associated with mottled depigmentation. With laser toning being frequently performed, this complication may become more commonly encountered in clinical practice. The depigmentation can appear after only a few treatment sessions, and can cause much disfigurement, especially in cases with background melasma. Further studies on laser toning are needed with the view to optimizing efficacy and minimizing side-effects.

Objectives: The present study examined the factorial invariance and functional equivalence of the Values in Action Inventory of Strengths (VIA-IS) among the Chinese. Methods: A total of 839 undergraduate students completed the 240-item Simplified Chinese version of the VIA-IS online. Another 40 students participated in qualitative interviews to examine the meaning and function of the items in Chinese culture. Results: A total of 144 items were removed from the original version questionnaire (240-item) because of low item-loading and lack of cultural validity. A Chinese Virtues Questionnaire-96 (CVQ-96) in simplified Chinese containing 96 items (4 items per strength) was adopted. Three subscales (interpersonal, vitality, and cautiousness) were developed after exploratory factor analysis and confirmatory factor analysis. Conclusion: A theoretically meaningful 3-factor model of virtue, comparable to some virtue structures proposed in previous studies conducted in Western countries, was obtained. The inventories being developed can facilitate positive social work assessment and intervention.

Ablative fractional CO₂ laser resurfacing was overall safe and effective for skin rejuvenation and acne scars in Asians. However, in view of the high post-inflammatory rate and the statistically significant but only mild to moderate improvement after a single treatment as observed in this study, there is a need to review the current role of fractional ablative CO₂ laser treatment as compared to fractional non-ablative for skin rejuvenation and acne scar treatment in Asians.
