Seriously Sharron, try olive oil from your kitchen. Just a teeny tiny dab on your finger tip patted all over your face does amazing things. Molecularly it is the most similar oil to the oil our skin naturally produces.
I know it seems a bit wonky but think of it like this... olive oil is in many high end products.
If you would rather try a packaged moisturizer.... St Ives makes a Essential Moisturizer that is lovely and very low in cost. Here in the states a 340 gram tub sales for 3 US dollars.
While youre looking around the shelves of your store do pay attention to moisturizers that offer an SPF... I am severely lacking in that area and it is so very important.
