What is dry lips after kissing?

Dry lips after kissing can occur due to a lack of moisture and hydration in the lips. Kissing can cause the lips to become chapped and dry due to the constant pressure and friction between the lips. Additionally, saliva can also cause dryness as it contains enzymes that break down the natural oils in the lips. This can lead to a loss of moisture and leave the lips feeling dry and cracked. To prevent dry lips after kissing, it is important to stay hydrated, use lip balms with natural oils and butters, and avoid excessive kissing without taking a break to rehydrate the lips.
