Oral sunscreens can only be beneficial when they are used as an extra protective measure against damaging UV rays and not singularly, warns a dermatologist.
Oral sunscreens contain extracts of the cabbage plant. Dr. Rebecca Tung, MD, director, Division of Dermatology reported that these products have powerful antioxidant and anti-inflammatory properties that can clear up free radicals, which cause cellular damage in the body.
Yet they are not 100 percent effective because they work based on the body's ability to absorb them, which can vary from person to person.
She said that while oral sunscreens are appealing as they don't leave a sticky white residue or need to be applied frequently, traditional lotions, creams and protective clothing remain the most effective way to block the sun.
