I am trying this next. http://www.3m.com/product/information/Cavilon-Durable-Barrier-Cream.html
Here is the summary of a clinical trial by 3M. Note: they are looking at wash off times as opposed to rub off times.
Interestingly, the article concludes that dimethicone concentration does not correlate with efficacy.
I do NOT want something smelly with anti-bacterial (Sensitivity to topical antibiotics can develop over time. Neosporin sensitivity is very common.) or anti-fungal agents!
[Back to Eucerin's Auaphor Healing Cream for a moment, it is readily available in 0.14 oz/3.4 g tubes. I have seen this product by Eucerin in many different European and Asian countries although it is not necessarily labeled "Aquaphor".]
I have used Badger Baby Balm (fragrance free) on susceptible areas of the feet and it does alright. Good on the hands, lips, face too. The small tin is very hard to find.] I have also used Burts Bees hand salve (available in tiny tin) and the thick Neutragena Hand Cream (Unscented). Again, OK.
I use the stuff after cleaning my feet in the evening and before putting my sneakers on in the morning.
As for reusing any sachets, one can p rick (that's a naughty word!) the sachet with a pin and use a bit of tape to cover up the hole). They are still a mess but I have found this works better than tearing off the top. Generally avoid sachets!
Here is one, I have NOT used -- Cramer Skin-Lube. http://www.cramersportsmed.com/products/training-room-supplies/skin-lube® In addition to other sizes, it is available in a 25 lb bucket! Reviews suggest it is messy.
