Hori’s Nevus

What Is Hori’s Nevus?

Hori’s Naevus presents as benign (harmless) blue-grey to grey-brown patchy and spotty pigmentation on the prominence of the cheeks. The condition usually appears in adulthood and is most common in middle-aged Asian women.
The condition is often misdiagnosed as it may resemble or coexist with melasma. It’s also known as Acquired Naevus of Ota-like Macules.

What Causes Hori's Nevi?

Genetics and hormones play a role in the development of Hori’s Naevus. When melanin pigments are present in the dermal layer of the skin, it causes a condition known as dermal melanocytosis. Dermal melanocytosis is a spectrum of conditions and includes Mongolian spots, naevus of Ota, Hori’s Naevus and naevus of Ito.

 

What Does It Look Like?

Hori’s Naevus often appear on both cheeks symmetrically, appearing as small, greyish-brown to blue-grey spots. They are less likely seen over the temples, nose, eyelids and forehead.

In-Clinic Treatments

Hori’s Naevus can be treated with the Q-switched Nd:YAG laser. Multiple sessions (at least 4) are usually necessary. Temporary tanning of the skin (Post-Inflammatory Hyperpigmentation) may occur, however, this usually settles over time.

Can I Still Do Other Aesthetic Treatments if I Am Treating My Pigmentation?

Pigmentation treatments are not generally contraindications against undergoing other non-abrasive or non-resurfacing treatments. This means that it is very common for patients to concurrently treat their dark spots, and also go for fillers, Ultherapy, Radiofrequency Skin Tightening and more, concurrently.
