Hori Naevus

Hori naevus is one of the most common causes of pigmentation seen primarily in Asian women. It occurs on both cheeks & can be effectively treated with Picosure Pro laser. We can achieve marked improvement in most cases, with little to no side effects using the very latest lasers. Once treated, recurrence is rare.

The science of Hori Naevus Treatments

  • Hori naevus is a common cause of pigmentation in Asian females
  • It is often seen in the 30s to early 50s
  • Picosecond lasers provide the best clearance
  • Treatments are painless with little to no recovery time

The picosecond laser has revolutionized Hori Naevi treatments. Pigment is cleared twice as fast with much less side effects. Picosure Pro provides fast clearance without any downtime.

What is Hori naevi?

Hori naevus or naevi are brown to gray dots that appear around the eyes in Asian women. Hori starts at around 30 years of age & progressively darkens over the decades. The only way to treat Hori is with specific pigment lasers.

What is the best way to treat Hori naevus?

Pico lasers such as Picosure Pro are the best way to treat Hori naevi. Lasers offer fast, safe & effective removal of pigmentation, especially in Asian skin.

At The Melasma Clinic we employ both Picoway & Picosure Pro in our Brisbane & Sydney locations.

What results can I expect from a Pico lasers?

To date, this is the most effective laser for Hori, as over 92% of cases can be cleared with pico. Additionally, side effects such as hypo (skin lightening) or hyperpigmentation (skin darkening) is much less as compared with older nano lasers.

How many sessions will I require to clear Hori naevi pigmentation?

Though results can be seen within one laser session, we advise a series of 6 sessions, spaced 4-10 weeks apart.

For deeper pigmentation Hori will require several additional sessions for removal.

What is the treatment like?

Treatments are comfortable & fast, taking less than 2 minutes to perform. Picosure feels like tiny nettle flicks on the skin. On a pain scale of 1 to 10, it rates as a 1 to 2.

What is the recovery following Picosure Pro for Hori?

There are two settings we use to treat Hori (depending on your expectations & recovery time). These settings will be discussed with you prior to treatment.

  • Slow & steady. This setting takes treatment recovery into consideration. Treatment recovery is uneventful with mild redness after the laser. You will require more pico laser sessions with this setting.
  • Speedy & spotty. This may give you some mild but short lived increase in the pigment (only to spots) & redness that may last a few days. You will require less treatments with this setting. Post laser skin darkening may last weeks with this setting.

Can creams fade pigment due to Hori?

Creams have a marginal effect on Hori naevus as the pigment lies in the deeper layers of skin. We do however recommend pigment correctors after laser as –

  • Hori naevi often occur with other forms of pigmentation such as melasma.
  • Laser can occasionally activate pigment cells in the upper layers of skin.

The ideal cream formulation will be determined by your dermatologist.

Will Hori naevus return after treatment?

Once cleared the chances of recurrence is low, however most patients will have pigmentation due to other causes such as melasma & age spots. Simple skin care & sunscreen will help reduce recurrences.

The Melasma Clinic treats all forms of pigmentation

Our specialist clinic is overseen by dermatologists who have extensive experience in the treatment of darker skin types, including management of Hori & Ota naevi. Our doctors have spent many years lecturing in Asian countries on the topic of pigmentary disorders. Combined with the very best in laser technology they deliver outstanding results in the shortest possible time.

Are there any side effects of Picosure laser?

Side effects are rarely seen with pico lasers as they offer a precise way of pigment removal in Asian skin. In some cases we can expect transient & short lived (weeks to months) hyperpigmentation, especially if higher power is used. You will be forewarned if this setting is used.

If I can identify the cause of pigmentation, chances are I can treat it. This can only be achieved with careful real time examination…

A SummaryTreating perioral pigment/ dark hyperpigmentation around the mouth

Dr Davin Lim | Dermatologist
The Melasma Clinic, Brisbane | Sydney

The diagnostic & treatment algorithm for dark patches around the mouth area (perioral hyperpigmentation) is even more complex than dark circles. Most cases are multifactorial, given the extraordinary amount of marketing, DIY tips, blog posts & accessibility to skin care ingredients. What starts off as a self-limiting inflammatory rash, leads inevitably to rip roaring irritant contact dermatitis as most patients will ‘have a go’ at treating the rash, & resulting pigmentation. 

As with all cases, identifying the cause of the pigment is paramount to effectively (in most cases) treating perioral hyperpigmentation. Once the provisional diagnosis has been made (most often by myself), I refer patients to my colleagues for investigations & medical management. It can be as simple as perioral dermatitis or as complex as occult allergens in foods, toothpaste, skin care & more. If the rash is not obvious, extensive patch testing is required by an allergist, or a dermatologist with an interest in patch testing. 

Once inflammation has subsided, we then can offer laser treatments. My favourite laser is the pico, with a large spot size with low power – energy settings. It is very effective in treating post-inflammatory hyperpigmentation, but highly ineffective in treating genetic causes of perioral pigmentation.

*Diagnosis of perioral pigmentation is more complicated than the description above. Dermatologists are also aware of rare causes. Examples include drugs such as clofazimine (made harder because it is used to treat Ashy dermatosis), amiodarone, silver, fixed drug (usually solitary or multiple circumscribed blue to grey patches) as well as genetic causes.
