Hey Barb,
I hope the balm works for you!!! Yes, the sun is proven to help - the plastic surgeons and derms are now offering the light therapy in office which is thought to help....Guess we should start listening to our grandmas!
Hopefully, one day there will be a cure!!
I know she put that balm on about 3 times a day for several weeks and then it just disappeared.

Sadly, she had spent thousands prior on rx creams, injections and such that never helped. She still tells everyone that story.
Good luck and I know the ointment (it's actually in a big tub/container) made by Eucerin called Aquafore is very good for moisturizing extremely dry skin. The plastic surgeons recommend this after some laser treatments. The Aquafore is in an ointment form but Eucerin also makes a lotion with the same ingredients minus the petroleum - if the ointment is too greasy (should be right next to Aquafore in the same type of container.
