Q-switched Nd:YAG 雷射是一種眾所周知的治療皮膚表層和深層色素斑點的方法。通常需要多次治療才能獲得良好效果。已提出使用 low-energy Q-switched 1064nm Nd:YAG 雷射 (multi-pass technique and larger spot size) 作為治療黃褐斑的方法。
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 又稱蒙古斑。這是新生兒常見的一種胎記。它從出生時或出生後不久就在皮膚上表現為灰藍色斑塊。這些標記通常出現在下背部和臀部，肩膀是下一個常見的位置。它們在亞洲和黑人嬰兒中更為常見，對男孩和女孩的影響相同。通常，它們會在 1 至 6 歲時自行消失，通常不需要任何治療，因為它們大多是無害的。
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.
