Hello Twin Mum and Kim
I have also been very happy with Lachydrin 12% lactic acid, but when the temperatures drop in January and February, I add glycerin to help with keeping the moisture in. It is very inexpensive and the smell is pleasant. Twinmum, some of the ingredients you might like to experiment with are urea,lactic,glycollic, or salicyllic acids. Other products I see on some of my samples are ceramides, glycerin, allantoin, Vitamin E, cholesterol, and fatty lipids. Those are just a few of the ingredients listed on my samples. I hope this helps.
