Why does Australian sunscreen have its own standard?
Sunscreen sold in Australia is regulated by the TGA rather than treated purely as a cosmetic, and products must be tested to the AS/NZS 2604 standard. That covers SPF rating, broad spectrum performance and water resistance claims, which is why testing here is generally regarded as among the more rigorous internationally.
What does broad spectrum actually mean?
That the product protects against both UVB, which is primarily responsible for burning, and UVA, which penetrates more deeply. SPF alone only describes UVB performance, so a high SPF without a broad spectrum claim is only covering half the picture. Look for both on the label.
How much do I need to apply?
More than most people use. The standard testing assumption is around a teaspoon for the face and neck, and roughly 35ml for a full adult body. Applying half the tested amount does not give you half the SPF — the drop-off is steeper than that. Reapply every two hours, and after swimming or towelling.
Does SPF in makeup count?
Not as your primary protection. The amount of foundation or CC cream applied for cosmetic coverage is well below the tested quantity, so treat it as a supplement to a dedicated sunscreen rather than a replacement.
