La Roche-Posay has given its cult SPF an upgrade, and it’s currently on sale

We all know how important SPF is by now – basically, you need to be wearing it everyday to make sure you’re protecting your skin from harmful rays. One cult SPF product that shoppers can’t get enough of comes from La Roche-Posay – the brand’s Invisible Fluid is hailed a favourite for its lightweight, non-greasy texture.

But now, La Roche-Posay has upgraded its SPF to be even better for our skin. It’s called Anthelios UVMune400 Invisible Fluid spf50+ and it promises to provide a new form of sun protection, specifically designed to protect skin from the rays most associated with the signs of premature ageing.

So what makes it so different? This new version contains Mexoryl 400, which is the ‘most efficient filter’ against UVA rays. The latest research has shown that UVA rays damage collagen structures in the skin, which can lead to a loss of elasticity, wrinkles, sagging, and create abnormal pigmentation patterns (aka sun spots or age spots). But don’t worry, the new formulation retains the same non-greasy, non-sticky feel with an invisible texture, ensuring it’s still suitable for all skin types.

If you’re still wondering how this seemingly magical ingredient works, we spoke to dermatologist Dr Hiva Fassihi to break down why the addition of Mexoryl 400 is so important.

‘Mexoryl 400 is a new UV filter from L’Oreal found in Anthelios UVMUNE400 sunscreen that specifically targets ULTRA-LONG UVA wavelengths (380-400nm),’ she starts.

Okay, back up. What are UVA rays?

‘The sun emits ultraviolet radiation (UVR) as well as visible light and infrared rays. UVR is the main cause of sun damage and is divided into UVB and UVA rays. UVB only penetrates as far as the top layer of the skin and can cause sunburn. It causes direct damage to the DNA in the skin cells, and with repeated exposure can result in skin cancers. But UVB is blocked by windows and clothing.

‘In contrast, UVA penetrates deeper in to the skin and mostly causes skin ageing. UVA is not blocked by obstacles like clouds or windows, but still damages the DNA in our skin cells.’

How does Mexoryl 400 work against that?

‘This new filter is able to cover the longest UVA rays – wavelengths not efficiently covered by current sunscreens. Mexoryl 400 is able to prevent long UVA induced cell damage deep in the skin. As a result, this filter is more effective against wrinkles and pigmentation.’

What’s the key difference between the new La Roche-Posay Anthelios sunscreen and the previous one?

The addition of the Mexoryl 400 filter will make it an even more effective broad spectrum sunscreen. Anthelios remains an excellent UVB and short UVA sunscreen but now also targets the ultra-long UVA wavelength.
