Lasers and light sources, as well as other energy devices, including radiofrequency, ultrasound, and cold-based therapies, can be used for treatment of aging, dyschromic, or texturally uneven skin. In patients with ethnic skin (ie, skin of color), energy devices are used more cautiously to avoid adverse events. The most common and concerning adverse event is postinflammatory hyperpigmentation. Lower fluence, longer pulse durations, and careful device selection can mitigate the risk of scarring and pigmentary abnormality...

Melasma is an acquired disorder of symmetrical hyperpigmentation commonly seen in patients with Fitzpatrick skin types III and IV. Various novel therapeutic modalities have emerged to treat melasma. The large-spot low-fluence QS Nd:YAG laser has been widely used in Asia; however, the modality needs to be optimized because of the high recurrence rate. The objective of this study is to explore the clinical efficacy and safety of fractional-mode (Pixel) Q-switched neodymium-doped yttrium aluminum garnet (Nd:YAG) 1064-nm laser for treatment of melasma in Chinese patients...

Nowadays, laser therapy is a common method for treating various dermatological troubles such as acne and wrinkles because of its efficient and immediate skin enhancement. Although laser treatment has become a routine procedure in medical and cosmetic fields, the prevention of side-effects, such as hyperpigmentation, redness and burning, still remains a critical issue that needs to be addressed. In order to reduce the side-effects while attaining efficient therapeutic outcomes, it is essential to understand the light-skin interaction through evaluation of physiological changes before and after laser therapy...

Dyschromia is a leading cause for cosmetic consultation, especially in those with diverse skin types (mixture of ethnicities) and with the rise of non-core and untrained physicians performing cosmetic procedures. Melasma and post-inflammatory hyperpigmentation (PIH) account for the majority of cases and are characterized by pigmented macules and patches distributed symmetrically in sun-exposed areas of the forehead, cheeks, and chin in melasma, and irregularly in areas of inflammation or an inciting traumatic event with PIH...

Periorbital hyperpigmentation is a commonly encountered condition. There is very little scientific data available on the clinical profile and pathogenesis of periorbital hyperpigmentation. Periorbital hyperpigmentation is caused by various exogenous and endogenous factors. The causative factors include genetic or heredity, excessive pigmentation, postinflammatory hyperpigmentation secondary to atopic and allergic contact dermatitis, periorbital edema, excessive vascularity, shadowing due to skin laxity and tear trough associated with aging...

Melasma is one of the most common pigmented lesions in Chinese women. Although topical therapies are the mainstay treatment, lasers are being used increasingly to treat pigmented lesions. Laser treatment of melasma is however still controversial. This is because lasers have not been able to produce complete clearance of melasma and recurrence rates are high. Laser treatments also cause complications such as hypopigmentation and post-inflammatory hyperpigmentation. In this article, we report on a novel technique using a combination of fractional 2940-nm Er:YAG and 1064-nm Q-switched Nd:YAG lasers...
