However, if the dryness progresses to the point where your lips are cracked or repeatedly split, it may take some time for them to become plump again.
According to Ms. Fujii, "Lips are a part of the face that is meant to be 'adorned,' so if they are inflamed or cracked, it can give a very negative impression to others. These days, even men carry lip balm with them. It's possible that the condition of your lips is attracting more attention, so if you notice even the slightest cracking, take action as soon as possible!"
For lips that are not simply dry but have developed "angular cheilitis" or "cheilitis," proper treatment with medication is the quickest way to recovery. For example, Mentholatum's "Medical Lip" contains allantoin, which promotes the repair of chapped lips, and vitamin B6 (pyridoxine hydrochloride), which promotes skin metabolism, making it effective for peeling and cracking lips.
"It looks thick and rich, but it spreads surprisingly well when you apply it. The way it slowly penetrates the skin makes me feel like it's more than just moisturizing, which is reassuring. I don't think it would sting even if you applied it to chapped lips," says Fujii.
