As you say, there is nothing to lose and it is just very easy to do it !
What is certain is that, biologically, all the alive entities have optimal conditions which enable them to be at their maximum of productivity.
We don't derogate from the rule and we are just a huge pack of cells and what is certain is that lips are severely affected, in the bad way, by COLDNESS and DRYNESS, then wind which makes worse these two elements.
The 'steam' treatment is not insignificant at all, and let us know how your condition will evolve.
I repeat, do not rubbing your lips when they are wet after a steam session but let them to be impregnated, which lasts about less than a half hour.
For ones who have not really the natural lips resiliency, try to do some stretchings during the steam session. Anyway, the resiliency will come back.
