ReferencesRiehl melanosis e masani ona lauiloa o le pigmented contact dermatitis. O se ituaiga o dermatitis e mafua mai i allergies, e masani lava ona faʻaosoina e le manogi ma isi mea e maua i mea teuteu. E ui ina faʻaavasegaina o se ituaiga o dermatitis, Riehl melanosis o loʻo faʻaalia ai hyperpigmentation i le paʻu, ma pigment incontinence ma suiga eczematous (eczema) laiti. E sili atu ona taatele i tagata dark‑skinned people. O su’esu’ega talu ai nei na su’esu’eina ai le aoga o le mid‑fluence QSNY 1064‑nm laser leisa togafitiga mo le faʻatalanoaina o le loloto o le lanu e fesoʻotaʻi ma le Riehl melanosis. O le isi su’esu’ega na tuʻu faʻatasia ai togafitiga eseese, e aofia ai le low‑fluence 1064‑nm Q‑switched Nd:YAG laser, hydroquinone cream, ma le oral tranexamic acid, ma iʻu ai i le faʻaleleia atili o le tele o gasegase.
Riehl melanosis (RM), commonly called pigmented contact dermatitis, is considered an acquired form of allergic contact dermatitis, typically to fragrance and other ingredients of cosmetic products. Although it is considered as a dermatitis, it presents clinically with hyperpigmentation over the face and shows pigment incontinence with minimal eczematous changes on histology. The condition is more commonly seen in dark-skinned people, causing an important psychosocial impact. A recent study showing the higher effectiveness of mid-fluence QSNY 1064-nm laser in targetting the deep pigmentation of RM has also been conducted. Another study used a combination of therapies to include low-fluence, 1064-nm, Q-switched Nd: YAG laser, hydroquinone cream, and oral tranexamic acid, with the majority of patients experiencing significant improvement.

Mo le togafitiga, ua uma ona fa'ata'ita'iina vaila'au fa'aleaganu'u ma le laser, e masani lava fa'atasi ma le fa'aogaina o vaila'au fa'apipi'i e fa'aoga i le pa'u. Leisi togafitiga, aemaise lava le fa'aogaina o le Q-switched Nd:YAG laser, ua fa'aaalia i'uga lelei mo le togafitia o le Riehl melanosis. O le tu'ufa'atasia o togafitiga eseese e taʻita'i ai i'uga lelei.
Riehl's melanosis (RM) is a contact photodermatitis, with fast progressive gray-brown skin pigmentation as the main manifestation, which can seriously affect the psychology and physiology of patients. Currently, although the etiological factors of Riehl's melanosis is still be unknown, the existing literature proves clearly the cause of it is related to the contacting with suspected allergens. For decades, there has been no standard method for the treatment of RM, but with both conventional drug therapy and laser therapy having been attempted. Topical application of bleaching agents is mainly used as an auxiliary treatment modality. The laser treatment modality remains a hot spot, among which Q-switched Nd:YAG laser is well received for RM. Positive outcomes have been achieved by the combined treatment modalities attempted in recent years also achieve positive outcomes.
