research Topical Retinoids: Therapeutic Mechanisms in the Treatment of Photodamaged Skin

69 citations , March 2016 in “American journal of clinical dermatology”

Topical retinoids effectively improve photodamaged skin.

research Modeling of solar UV-induced photodamage on the hair follicles in human skin organoids

January 2024 in “Journal of tissue engineering”

In this study, researchers used a human skin organoid model to show that solar UV exposure damages hair follicles and skin, while exosomes from mesenchymal stem cells reduced inflammation and supported hair follicle regeneration.

research Adipose tissue protects against skin photodamage through CD151- and AdipoQ- EVs

December 2024 in “Cell Communication and Signaling”

This study found that subcutaneous adipose tissue-derived extracellular vesicles (AT-EVs) protect skin from photodamage by enhancing fibroblast proliferation and reducing oxidative stress compared to those from adipose-derived stem cells.

research Redox-directed interventions targeting skin photodamage

August 2015 in “Free Radical Biology and Medicine”

Some treatments can improve skin's defense against damage, but overuse may cause other skin problems.

research The risk of hydroquinone and sunscreen over-absorption via photodamaged skin is not greater in senescent skin as compared to young skin: Nude mouse as an animal model

18 citations , May 2014 in “International journal of pharmaceutics”

This study found that UVA and UVB exposure increased hydroquinone and sunscreen absorption in nude mouse skin, with less absorption enhancement observed in more lipophilic sunscreens.
