Does an SPF primer replace sunscreen?
Generally not. Sun protection factor is tested at an application density most people never reach with a primer, which is applied thinly for cosmetic reasons. Treat SPF in a primer as a useful supplementary layer rather than your main protection, particularly in Australian conditions.
How does a primer with SPF differ from sunscreen?
Primers are formulated first for how makeup sits on top — grip, blurring, oil control — with sun protection added. Sunscreens are formulated first for protection. That difference shows in texture: primers tend to be silkier and less occlusive, which is why foundation applies better over them.
In what order should I apply it?
Moisturiser, then sunscreen if you are using a separate one, then primer, then foundation. Allow each layer a moment to settle. Applying foundation immediately over a wet primer is the most common cause of pilling.
Which primer type suits my skin?
Silicone-based blurring primers smooth texture and suit visible pores. Mattifying primers control shine on oily skin. Hydrating and illuminating primers add glow for dry skin, though they reduce foundation wear time slightly. Match to skin type, not to the foundation.
