Extracellular vesicles from adipose-derived stem cells ameliorate ultraviolet B-induced skin photoaging by attenuating reactive oxygen species production and inflammation

Stem Cell Research & Therapy, 2020
Background Large numbers of adipose-derived stem cells (ADSCs) are easily obtained and have been demonstrated to protect against ultraviolet B (UVB)-induced skin photoaging.

Protective effects of extracellular vesicle‐like nanoparticles derived from Cannabis sativa adventitious roots against UVB‐induced damage in human keratinocytes

International Journal of Cosmetic Science, EarlyView.
Cannabis sativa root‐derived extracellular vesicle‐like nanoparticles (CA‐NPs) were isolated from adventitious root cultures and subjected to physicochemical characterization. Upon UVB exposure, keratinocytes exhibited increased ROS generation, apoptosis and MAPK activation, leading to oxidative stress and skin damage.

Photoaging/photodamage and photoprotection

Journal of the American Academy of Dermatology, 1990
Exposure to sunlight can produce both acute and long-term effects. Acute changes include erythema, photosensitivity, and immunologic alterations. Long-term consequences include carcinogenesis and photoaging. All effects can be minimized by photoprotection. This article reviews the adverse effects of sun exposure and strategies to reduce photodamage.

Bakuchiol: From structural mimicry to systems‐level skin biology

International Journal of Cosmetic Science, EarlyView.
Convergent outcomes, divergent mechanisms: bakuchiol vs. retinol. Bakuchiol exhibits functional convergence with retinol in improving extracellular matrix integrity, epidermal differentiation and barrier function, while operating through distinct mechanisms.

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)

Trans‐resveratrol alleviates inflammation and improves skin barrier function via aryl hydrocarbon receptor pathway in human reconstructed epidermis

International Journal of Cosmetic Science, EarlyView.
In a cytokine‐challenged human epidermal model, trans‐resveratrol reduces inflammation (IL‐1α) and oxidative stress markers (CYP1A1, CYP1B1), while modulating the expression of barrier‐related genes (LOR, OCLN) and differentiation‐associated CASP14. This supports its role as a multifunctional active for sensitive and compromised skin.

Recombinant human collagen XVII protects epidermal stem cells from blue light-induced photoaging by downregulating the Notch pathway

Annals of Medicine
Background Epidermal stem cell (ESC) degeneration is closely associated with skin aging and functional deterioration. Type XVII collagen (COL17A1) critically regulates ESC polarity and epidermal homeostasis. This study investigated the protective effects
