I use lip balm all the time in the winter, because my lips chap really easily. I've found that a lot of products seem to work for a little while, but in the long run seem to cause more chapping, creating a vicious cycle of constant use. This is by far the BEST product I've found for them...after one application my lips already started to heal, and after two applications they were completely healed and stayed that way! Also, I didn't constantly have to reapply throughout the day to keep up the benefits. As long as nothing changes with this formula, I will be a loyal fan for life!
