Riehl melanosis idla ngokubizwa ngokuba yi‑pigmented contact dermatitis. Luhlobo lwemeko yolusu olubangelwa kukwalana, ngokuqhelekileyo lubangelwa livumba elimnandi kunye nezinye izinto ezifumaneka kwiimveliso zokuthambisa. Nangona ihlelwa njengohlobo lwe‑dermatitis, iRiehl melanosis ibonisa utshintsho lwe‑pigmentation esikhumbeni, kunye neempawu ezincinci zokucaphuka. Ibonakala ngakumbi kubantu abanolusu olumnyama. Uphando lwakutsha nje luphonononge ukusebenza kwe‑mid‑fluence Q‑switched 1064‑nm unyango lwelaser ukujongana nobunzulu bebala elinxulunyaniswa ne‑Riehl melanosis. Olunye uphononongo ludibanise amayeza ahlukeneyo, kubandakanywa i‑low‑fluence 1064‑nm Q‑switched Nd:YAG laser, i‑hydroquinone cream, kunye ne‑oral tranexamic acid, okuye kwakhokelela ekuphuculeni okubonakalayo kwizigulane ezininzi.
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.

Riehl's melanosis luhlobo lwemeko yolusu olubangelwa kukudibana nezinto ezithile ezingezwani kunye nokuvela elangeni. Ikhokelela kwibala elikhawulezayo, eliqhubela phambili elingwevu‑mdaka eluswini, elinokuchaphazela kakhulu izigulana ngokwasengqondweni nasemzimbeni. Ngelixa imbangela ye‑Riehl's melanosis ingakacaci, uphando olukhoyo lubonisa ikhonkco eliqinileyo kunye nokuvezwa kwe‑allergen. Unyango, amayeza esintu kunye nonyango lwelaser sele lwazanywa, ngakumbi ekusetyenzisweni kwama‑agent afakwa kwi‑bleaching esikhumbeni. Unyango lwe‑Laser, ngakumbi kusetyenziswa i‑Q‑switched Nd:YAG laser, lubonise iziphumo ezithembisayo zokunyanga i‑Riehl's melanosis. Ukuhlanganiswa kweendlela ezahlukeneyo zonyango kuye kwakhokelela kwiziphumo ezilungileyo.
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.
