Did You Know?

You can buy a face cream for $930?

A face cream containing 24-carat gold promises anti-aging technology (advanced phytosterone) by reducing the appearance of lines, wrinkles and age spots.

The particles in the cream reflect and scatter light and consequently help alter the appearance of the skin's surface.

Enhances the reflective properties of skin itself, making it luminous from the instant of application.

That’s $31 for 1 ml!

DEMAND for luxury skincare is soaring in Australia, as women snap up creams and serums that cost hundreds of dollars for tubs that contain 100 millilitres or less.

How do we make informed decisions l.jpg
How Do We Make Informed Decisions?

A new shampoo uses 'NANO' directly as its brand.

The shampoo, claims to contain titanium dioxide (TiO2) nanoparticles, which could penetrate more effectively into the hair and, thanks to its photocatalytic oxidation characteristics, oxidize the harmful residues after hair perming.

Would you buy this shampoo?
