Topical Rosacea Treatments
Paraben Preservatives and Sun Damage
Rosacea symptoms are provoked and worsened over time by incremental daily light exposure, irrespective of season or cloud coverage.
Accordingly, daily sunscreen use has become an important part of rosacea treatment.
A recent study (Methylparaben potentiates UV-induced damage of skin keratinocytes — Toxicology , Volume 227 , Issue 1 - 2 , Pages 62 - 72) demonstrated that the paraben preservative methylparaben worsens skin's response to daylight:
UVB exposure significantly increased cell death [skin aging], oxidative stress [skin inflammation], NO production [skin aging], lipid peroxidation [free radical production] and activation of transcription factors in MP-treated HaCaT keratinocytes. These results indicate that methylparaben, which has been considered a safe preservative in cosmetics, may have harmful effects on human skin when exposed to sunlight.
In light of the mounting evidence against parabens, it seems prudent to avoid them where possible.
