We hear a lot about skin dehydration this time of year. Yes, as the temperatures drop, our skin tends to need a little more moisture than usual, however, if you've oily skin then you might think that rule doesn't apply to you. Well, believe it or not, oily skin can still become dehydrated with signs such as dullness, fine lines and sensitivity all pointing to dehydration. But for those of us who spend our days blotting away excess oil, the idea of adding extra moisture to our beauty routine seems totally counterproductive. Enter skin miracle worker hyaluronic acid. For those of you well-versed in all things skincare, you’ll have heard of the ingredient many times before but for those of you with oily skin, you might not have realised that it could be the key to keeping skin hydrated without overloading it with product. Hyaluronic acid works to keep skin refreshed and renew skin cells but the biggest benefit is its ability to help skin retain water. This keeps skin looking plumper and reduces the appearance of fine lines and wrinkles. And what’s even better is that the product is super lightweight and perfect for those with oily skin who might be scared of adding too much moisture to the mix. It also works well for sensitive and blemish-prone skin for the same reason. One of the most popular products containing the hydrating ingredient is The Ordinary's Hyaluronic Acid 2% + B5 which can be used morning and night.
