I have used this product for years. The ozonated olive oil and the silver gel (which I bought somewhere else) have proved the most effective treatment I've found for leg ulcers and I've tried many. My son works long hours in a kitchen, which means a lot of time standing and then he gets an ulcer from time to time, a downside of the job I'm afraid. This stuff, is brilliant to condition the skin and aid the healing process. It is painful if it gets onto the ulcer, however, it is also most effective if used occasionally to change things up from the silver gel, when the ulcer seems to be resisting the selver gel. Prescribed products, well don't get me started, useless or harmful, is all I can say about them.
This is an excellent product all round and you need such a small amount to make a huge difference to almost all skin conditions. It didn't work for us on eczema which was a disappointment, but it works on athletes foot and just about any other skin condition I've tried it on, it soothes haemorrhoids too.
