Without a doubt the most effective (and affordable) anti-ageing cream on the market is a really good sunscreen. So what makes a great sunscreen? It must be a broad-spectrum sunscreen, which means it protects against both UVA and UVB rays. It must be non-greasy and not leave your skin looking pasty white. And for the harsh Australian climate, it really needs to be at least an SPF 30+. Depending on your skin’s needs, we recommend the following sunscreens:Actinica SPF 30+ This is a liposomal sunscreen, and this delivery system means that the ingredients stay on the skin and are not absorbed into the skin. It’s great for those who spend a lot of time outdoors, especially swimming, but it’s non-greasy and works very well under makeup. $Skinceuticals Ultimate UV Defense SPF 30+ This sunscreen combines a physical sunscreen (it has 7% transparent zinc oxide) with a chemical sunscreen, so you really get the best of both worlds: the protection of a zinc with the creaminess and lightness of a chemical sunscreen. This is great to use in place of a moisturiser and perfect for under makeup.
