Antioxidant Sunscreens
Certain antioxidant sunscreens provide additional protection against photoaging outside of their ability to block or absorb the sun's rays.
Kinerase Pro+ Daily Defense Lotion SPF 30 with Kinetin and Zeatin is an example of a modern dermatological antioxidant sunscreen, priced at US $140.00.
Airless packaging is an important aspect of antioxidant sunscreen packaging. Rosacea Oil Free Antioxidant Daily Wear Sunscreen and Hypoallergenic Daily Wear Sunscreen are anti-inflammatory rosacea-specific examples.
Although less expensive sunscreens tout antioxidant capacity, it is unlikely that they contain relevant concentrations of antioxidants.
If fresh, chemically stable up to the point of use and able to penetrate skin, certain antioxidants formulated in combination (or applied underneath) sunscreens are able to provide increased photoprotection and therefore protection against worsening rosacea symptoms.
Rosacea Oil-Free Antioxidant Daily Wear Sunscreen provides an anti-inflammatory and antioxidant sunscreen formula including:
Vitis Vinifera (Grape Seed) Polyphenols, Green Tea (Camellia Sinensis) Polyphenols, Glycine Soja (Soy) Isoflavones, Silymarin (Milk Thistle) Silybin and Sodium Ascorbyl Phosphate (Vitamin C).
Unlike mass-produced sunscreens, the product is made freshly for each patient in the pharmacy and supplied in hermetically sealed packaging which includes an airless pump system.
The mode of production and supply of the sunscreen also allows for the elimination of paraben preservatives, which increase the burden of oxidative stress on skin and have been shown to heighten sun damage.
These two factors are extremely important in actually obtaining antioxidant protection from sunscreens because antioxidants are inherently unstable and prone to degradation when exposed to air.
Oxidized antioxidants may even be harmful.
