Q-switched Nd:YAG 激光是一种众所周知的治疗皮肤表层和深层色素斑点的方法。通常需要多次治疗才能获得良好效果。已提出使用 low-energy Q-switched 1064nm Nd:YAG 激光 (multi-pass technique and larger spot size) 作为治疗黄褐斑的方法。
The Q-switched Nd:YAG laser is a well-known treatment for pigmented skin spots, both on the surface and deeper layers. Usually, several sessions are required for good results. Using a low-energy Q-switched 1064nm Nd:YAG laser (multi-pass technique and larger spot size) has been proposed as a way to treat melasma.

Congenital dermal melanocytosis 又称蒙古斑。这是新生儿常见的一种胎记。它从出生时或出生后不久就在皮肤上表现为灰蓝色斑块。这些标记通常出现在下背部和臀部，肩膀是下一个常见的位置。它们在亚洲和黑人婴儿中更为常见，对男孩和女孩的影响相同。通常，它们会在 1 至 6 岁时自行消失，并且通常不需要任何治疗，因为它们大多是无害的。
Congenital dermal melanocytosis, also known as Mongolian spot or slate gray nevus, is one of many frequently encountered newborn pigmented lesions. It is a type of dermal melanocytosis, which presents as gray-blue areas of discoloration from birth or shortly thereafter. Congenital dermal melanocytosis is most commonly located in the lumbar and sacral-gluteal region, followed by shoulders in frequency. They most commonly occur in Asian and Black patients, affect both genders equally, and commonly fade by age 1 to 6 years old. Congenital dermal melanocytoses are usually benign and do not require treatment.
