Advances in organic UV filters for sunscreens over the past decade
Photochemistry and Photobiology, EarlyView.Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

Peptide and peptidomimetic tyrosinase inhibitors
Melanin, which is produced by melanocytes and spread over keratinocytes, is responsible for human skin browning. There are several processes involved in melanogenesis, mostly prompted by enzymatic activities. Tyrosinase (TYR), a copper containing metalloenzyme, is considered the main actor in melanin production, as it catalyzes two crucial steps that ...

Purification and characteristics of tyrosinase inhibitor produced by actinomycetes F-97
, 2008 An actinomycetes F-97 producing tyrosinase inhibitor was isolated from soil samples. Isolation and purification of tyrosinase inhibitor produced by F-97 was performed as follows: IRC-120 (NH4+ type) column chromatography, silica gel column chromatography,

Understanding exosomes in facial esthetics and skin aging
Periodontology 2000, EarlyView.Abstract Background Skin aging is a multifactorial process mediated by intrinsic (genetic and metabolic) and extrinsic (environmental) factors leading to functional and structural deterioration, including wrinkles, loss of collagen and elastin, as well as various pigmentation disorders.

Natural, semisynthetic and synthetic tyrosinase inhibitors
Journal of Enzyme Inhibition and Medicinal Chemistry, 2015 Tyrosinase plays a pivotal role in the synthesis of melanin pigment synthesis on skin utilizing tyrosine as a substrate. Melanin is responsible for the protection against harmful ultraviolet irradiation, which can cause significant pathological conditions, such as skin cancers.

Journal of Applied Toxicology, Volume 46, Issue 12, Page 4324-4339, December 2026.ABSTRACT Semi‐permanent make‐up (SPMU), or micropigmentation, involves implanting pigments into the dermal layer of the skin for cosmetic enhancement. Unlike topical cosmetics, which are rapidly cleared from the body, SPMU pigments persist in living tissues, raising unique toxicological considerations.
