PPD values aren’t measured as precisely as SPF numbers. In fact, there is no standardised system for determining them, so there is some ambiguity in their assessment. PPD is also known as PA, with plus signs (PA++) that signal UVA protection strength. The higher the PPD number or the greater the number of plus signs, the better a sunscreen protects against UVA rays.
It is important that you protect yourself from both types of UV rays by using a broad spectrum photo-stable sunscreen. Here’s our round up of some of the best broad spectrum sunscreens which contain good levels of PPD, as well as good quality, high level SPF.
