Topical Rosacea Treatments
New Treatment Topics
Photoaging (also described as sun damage) refers to skin aging due to all forms of daylight (visible, invisible ultraviolet A, B & C and infrared) which reach the skin.
The development and worsening of rosacea symptoms is also thought to represent a form of photoaging. Tests invariably show severe damage to the dermal matrix of rosacea patients' skins (characteristic of photoaging).
"Daylight represents any form of outdoor natural light, be it sunny or not, winter or summer, behind glass or not."
In other words, you will need to wear sunscreen while indoors in a naturally-lit environment and when making short trips in the car because the incremental exposure adds up over time.
According to the free radical theory of aging, skin cancer is also thought to represent severe photoaging.
Used as directed, rosacea sunscreens may be used to prevent photoaging and the further development and worsening of pre-existing rosacea symptoms, however please note that paraben preservatives in sunscreens have been shown to exacerbate photoaging and some rosacea symptoms.
