It's no secret that I have always been a fan of vitamin C when it comes to my skin. Over the years it's been one of the essential products in my skin care regime for many reasons, from its healing properties to the way it can brighten the skin and protect against damage from free radicals. 

However, a perennial problem with vitamin C is having the ingredient stable in a formula, and using a high enough concentration of it to be effective. While some products come in two parts which have to be mixed to maintain freshness, others contain vitamin C in a solution specifically designed to keep it as fresh as possible.

When you travel, the issues surrounding vitamin C stack up. Will constant changes in temperature affect the formula? And on a practical level, who wants to carry a product made up of two different items which have to be mixed every time you use it? Whether you are away for work, or a vacation, time is often precious.

Phloretin CF Gel is new and highly advanced product from SkinCeuticals which answers many of these pressing questions, and is based on some serious research. For one, the formula contains 10 per cent vitamin C, a decent dose, but it also contains two per cent phloretin, and 0.5 per cent feulic acid, creating a serum-in-a-gel which protects the skin from damaging molecules.

This lightweight gel doesn't have the most appealing colour or odour; it's slightly yellowy and has a kind of bland, earthy smell. But the gel formula has a light texture, making it easy to apply and spread across the skin; it blends in quickly and easily leaving your complexion feeling soft, and works well under makeup. It's also okay for anyone with problem or sensitive skins, so anyone can use it. 

They say the proof of the pudding is in the eating, and after six weeks of using this product, and through the heat and humidity of the Sydney summer, my skin feels and looks great. Phloretin CF Gel also comes in a small, lightweight pump container which makes it easy to slip into my toiletries bag for travelling - it will definitely become a regular member of my anti-ageing arsenal, both at home and on the road!
