It only took about 2 to 3 days. My lips are fine now. Nonetheless, I continue to put it on my lips. I'm not sure which one but together they worked well for me.
Although I resently got into the essential oils,through my research 100% pure essential oils are good for many things. I found out that lavender, camomile, and frankincense oils are good for skin iliments. As for Shea butter, it has been used for dry skin for years along with black soap. I hope this helps.
