Treatment of Acne‐Induced Facial Post‐Inflammatory Hyperpigmentation With a New 2‐MNG‐Containing Routine Versus a Thiamidol‐Containing Routine—A Monocentric Prospective Double‐Blind Randomized Comparative Trial

Journal of Cosmetic Dermatology, Volume 25, Issue 6, June 2026.
ABSTRACT Background Acne‐induced post‐inflammatory hyperpigmentation (PIHP) is a frequent condition. 2‐mercaptonicotinoyl glycine (2‐MNG) is an innovative anti‐pigmenting molecule. Aims The aim of this study is to compare the efficacy and tolerability of two routines in the treatment of PIHP: 2‐MNG‐containing serum + SPF50+/UVA sunscreen versus ...

Genomic Analysis of the Columbian Plumage Pattern in Various Chicken Breeds

Animals
Plumage coloration in birds is a complex genetic trait involving both direct pigmentation genes and their modifiers. The Columbian pattern, characterized by black feathers restricted to the neck, wing tips, and tail, remains poorly understood at the ...

DEPIGMENTING AGENT MELANOTOKSIK PADA PENGOBATAN MELASMA

Medical and Health Science Journal, 2018
: Human skin color is determined by melanin pigment,either eumelanin or feomelanin. Melanogenesis is a melanin synthesized process that is initiated with tirosin oxidation to DOPAquinone by tirosinase, and then auto-oxidation to DOPA and DOPAchrome ...

Pheomelanin in the skin of Hymenochirus boettgeri (Amphibia: Anura: Pipidae)

Experimental Dermatology, 2012
AbstractPheomelanin is supposed to be the first type of melanin found in vertebrates, in contrast to the main type – eumelanin. Our study aimed at detecting pheomelanin in the skin of Hymenochirus boettgerii. We employed electron paramagnetic resonance (EPR) spectroscopy, and transmission electron microscopy (TEM), supplemented with standard histology ...

Evaluation of Melanogenesis in A-375 Cells in the Presence of DMSO and Analysis of Pyrolytic Profile of Isolated Melanin

The Scientific World Journal, 2012
The increase of a skin malignant melanoma (melanoma malignum) incidence in the world has been observed in recent years. The tumour, especially in advanced stadium with metastases, is highly resistant to conventional treatment. One of the strategies is to

Analysis of femoroacetabular impingement by a triade of label-free optical spectroscopy techniques

Communications Biology
Understanding the biochemical mechanisms of hip joint diseases remains challenging. Femoroacetabular impingement (FAI) is a condition where developmental deformities of the hip joint reduce mobility and cause tissue damage, with characteristic red ...

Characterizing excited triplet states of synthetic eumelanin and pheomelanin by the application of selected diene probes

Scientific Reports
Although the role of excited triplet states in aerobic photochemistry of melanin pigments has been implicated, the molecular origin of the melanin subunits excited to triplet states and their key thermodynamic parameters remain unknown.

Coloration in Equine: Overview of Candidate Genes Associated with Coat Color Phenotypes

Animals
Variation in coat color among equids has attracted significant interest in genetics and breeding research. The range of colors is primarily determined by the type, concentration, and distribution of melanin pigments, with the balance between eumelanin ...
