Why Your Sunscreen Needs to Do More Than Just Block the Sun

In Australia, we know the sun is strong. But what many people don’t realise is that UV exposure accounts for up to 80% of visible skin ageing — and sunscreen is your first line of defence. The problem? Not all sunscreens are created equal.

At Platinum Cosmetics in Port Melbourne, we’re passionate about helping clients choose a sunscreen that protects not only from burns, but also long-term skin damage. That’s why we recommend broad-spectrum sunscreens that also include antioxidants to enhance their protective power.

The Difference Between SPF and Broad-Spectrum

SPF measures protection from UVB rays, which cause sunburn. But UVA rays, which penetrate more deeply, are just as damaging — contributing to collagen breakdown, pigmentation, and premature ageing.

Broad-spectrum sunscreens protect against both UVA and UVB. If your sunscreen doesn’t specify that, it may not be giving you full coverage.

Why We Recommend SkinCeuticals Sunscreens

We stock and recommend SkinCeuticals sunscreens because they combine clinically backed sun protection with added skin benefits.

Some of our favourites include:

• SkinCeuticals Ultra Facial Defense SPF 50+

  A lightweight daily sunscreen ideal for sensitive or dry skin. High protection without heaviness.

• SkinCeuticals Physical Fusion UV Defense SPF 50

  A 100% mineral sunscreen with a sheer tint that blends well under makeup or worn alone.

Each SkinCeuticals sunscreen is tested for photostability, ensuring the formula remains effective even after extended sun exposure.

Better Together: Antioxidants + Sunscreen

Using antioxidants and sunscreen together offers the best protection. Antioxidants (like those in SkinCeuticals C E Ferulic or Silymarin CF) help neutralise free radicals that sunscreen alone can’t block.

We recommend applying your antioxidant serum in the morning, followed by your SkinCeuticals sunscreen for full-spectrum defence.
