You know about the need to wear sunscreen. You know about the need for a sunscreen that protects you from both UVA and UVB rays. But are you confused about sunscreen ingredients and how they work? What about proprietary names, such as Helioplex (Neutrogena), and trademarked ingredients, such as Meroxyl FX (L'Oreal) and Parsol® 1789?
dermatology.about.com answers these questions and more. Heather Brannon, MD is the "guide" for dermatology.about.com. While Dr. Brannon is not a dermatologist (she is a family practice doctor), she has a definite interest in dermatologic topics.
Dr. Brannon's article Proper Use of Sunscreen describes the various kinds of ultraviolet radiations and classifies sunscreen ingredients as either physical barriers (for example, titanium oxide) or radiation absorbers, in addition to discussing appropriate application of sunscreen. Her article Sunscreen Information - Information About UVA Sunscreen Ingredients describes various UVA radiation absorbers, including Helioplex, Meroxyl FX, and Parsol® 1789.
Given the importance of wearing sunscreen, these two articles are must-reads.
In a subsequent article, I will mention recent innovations in sunscreen technology.
