This is a guide to Discovery Ruby compiled by Dr. Choi Byeong-geun of SHINE U Clinic Konkuk (3 minutes walk from Konkuk Univ. Station, Exit 1).
If you have blue or brownish-yellow spots on your face, you are likely to be concerned about your appearance. Nevus of Ota is often mistaken for melasma or blemishes and is only addressed after it has progressed. Today, we will summarize the characteristics of nevus of Ota and approaches to it.
What is Nevus of Ota?
It refers to the appearance of brown or blackish-blue spots, mainly on one side of the face, around the eyes, temples, forehead, or nose.
- Occasionally, it may appear on both sides.
- It is relatively common in Asians and rare in Westerners.
- It is known to be associated with the proliferation of melanocytes.
It can be congenital, or it can appear during puberty and gradually darken in color.
Easily confused with melasma
Since it often appears around the cheekbones, it is frequently mistaken for melasma at first and overlooked.
- Bilateral nevus of Ota can appear later, around the age of 20.
- The pigmentation can darken and spread due to sun exposure.
- If discovered, it is advisable to consult a specialist.
Why Ruby Laser is used
Nevus of Ota is characterized by being deeply embedded in the skin. Therefore, a ruby laser, which has a high melanin absorption rate and minimal impact on surrounding tissues and blood vessels, is primarily chosen.
- It is used to target deep pigmentation.
- The approach varies depending on the individual's skin type.
- The treatment period may differ depending on how long it has been present or its condition.
Even with the same equipment, the results are not identical, so accurately assessing the condition is important. Please consult with Dr. Choi Byeong-geun to confirm. If you have questions about nevus of Ota, please inquire via chat.
In summary
As nevus of Ota is a deep pigmentary disorder, accurate assessment and a personalized approach are important. Understanding its characteristics in advance can help in managing it. If you have any questions, please feel free to inquire via chat consultation.
