Natural Retinol Analogs Potentiate the Effects of Retinal on Aged and Photodamaged Skin: Results from In Vitro to Clinical Studies

Dermatology and Therapy, 2023
Introduction Plants are a source of natural ingredients with retinol-like properties that can deliver anti-aging benefits without the side effects typically associated with retinoid use. We hypothesized that by combining two such analogs, bakuchiol (BAK)

Matrix Metalloproteinases on Skin Photoaging. [PDF]

J Cosmet Dermatol
ABSTRACTBackgroundSkin aging is characterized by an imbalance between the generation and degradation of extracellular matrix molecules (ECM). Matrix metalloproteinases (MMPs) are the primary enzymes responsible for ECM breakdown. Intrinsic and extrinsic stimuli can induce different MMPs. However, there is limited literature especially on the summary of

Roles of oxidative stress in photoaging and the pathogenesis of systemic sclerosis [PDF]

, 2006
我々の皮膚は常に外界からの様々な刺激にさらされている．その刺激の代表的なものとして太陽光線中の紫外線があげられる．紫外線は皮膚癌の発生の誘因となる他に，紫外線の曝露により皮膚には光老化と称される変化が生じてくる．光老化の特徴的な変化として皮膚表面のびまん性の色素沈着と深い皺があげられるが，その変化を特徴づけるものとして皮膚真皮におけるsolar elastosisと称される膠原線維・弾性線維の変化がある．この皮膚光老化には紫外線による酸化ストレスが深く関与していると考えられている．一方 ...
