Paraben Preservatives and Sun Damage
Rosacea is encouraged and worsened by daily light exposure, irrespective of season or cloud coverage.
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, oxidative stress, NO production, lipid peroxidation 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.
Always use a suitable rosacea sunscreen when using skin care products containing parabens.
For additional important information, refer Avoid Parabens in Rosacea Skin Care.
