Rosacea Sunscreen Guide
New 2016 — Public Proof About Zinc
The sun has its benefits, however for rosacea patients it is the #1 trigger of their symptoms and therefore the most prevalent factor in worsening skin disease.
My rosacea patients who successfully avoid incremental, incidental sun damage and exposure year-round have demonstrably better outcomes than those who fail to protect themselves from the sun, irrespective of any other factors contributing to their rosacea.
Optimal sunscreen use contributes to the success of all other rosacea treatments: topical and systemic drugs, laser, IPL (intense pulsed light) and general skin care.
Although the cause of rosacea is not known and likely extremely complex, dermatologists can say with certainty that it is a photosensitive disorder.
Accordingly, if we choose the sunscreens we use carefully, and use them daily, we already have an extremely effective treatment for rosacea, and it is one which works by the superior method of prevention.
In addition, when patients use sunscreens daily to treat their rosacea, they also prevent the most obvious signs of skin aging (wrinkling, fine lines, colour and textural changes) by the most effective means currently available.
What Is Optimal Sunscreen Use in Rosacea Treatment?
Optimal use results in prevention of rosacea flare-ups, the prevention of blood vessel damage and great reductions in skin's reactivity, sensitivity, inflammation, redness and the prevalence of papules, pustules and broken capillaries.
Over the years I have refined a criteria for selecting an effective sunscreen for rosacea treatment, the technical details of which are elborated elsewhere on this website.
By following these criteria and making a careful selection of the sunscreens you use you'll reach the relatively inexpensive truth of what can really be meant by the generic recommendation that "sunscreen benefits rosacea" and radically alter the future of your skin.
Clarity in Purpose of Sunscreen
I believe the most peritent point about UV exposure which patients fail to adequately grasp is that it is incremental exposure to daylight (including through glass, for example while making brief trips in the car), over months and years, and not just prolonged warm or hot direct sun, which augments lasting, negative changes to skin's biological age, and increasing severity of increasingly treatment-resistant rosacea symptoms.
Recommended Rosacea Sunscreens
Sunscreen formulations have been changing more frequently than usual as maximum marketable SPF numbers have been revised and as the FDA has mandated changes to labels.
I do not mandate the use of any particular brand or product, but direct patients to this selection guide.
Update: 09/13 — By request, I have compiled a list of suggested sunscreen options. If you would like to suggest a sunscreen or provide feedback you are welcome to contact me through my Google Plus Profile.
Sunscreen chemicals and ingredients are common to many brands across different markets, in large part because there are only a few manufacturers of sunscreen chemicals, and because large cosmetic companies often own several brands.
I have noticed that L'Oreal replicates identical sunscreen formulas under different brand names.
Other sections of the website provide more technical and academic sunscreen information.
