Some people recommend exfoliating your lips first, using a lip scrub or, if you don't have one, a wet washcloth. This removes dead skin and improves absorption of the mask. Your lips also must be dry before applying the mask, or it might not stick to your face.
Check the ingredients before buying a mask for anything you know you are allergic to. If you use a mask and experience redness or irritation, remove it immediately and seek medical attention; likely you are allergic to something in there without knowing it.
You should not use a lip mask if you have broken or irritated skin on or around your lips. Some lip masks are solid and thus prevent you from breathing through your mouth; consider not using these if you have a stuffed up nose. It's generally better, however, to look for lip masks with a slit in them as they will cover more of your lips.
Do not eat or drink while wearing a lip mask, as you will likely knock it off. You also should not talk while wearing a mask, for the same reason.
Once you have removed the lip mask, you can apply lipstick right away. Lip masks don't leave any kind of colored residue on your lips, although the mask itself is sometimes colored.
Lip masks are also easy to use while traveling, as they don't require water or access to a bathroom.
Again, make sure your chosen lip mask doesn't contain ingredients which have caused you problems in the past. Choose a lip mask with a slot so you can breathe through your mouth and it covers more of your lips.
You should almost immediately see results in terms of plumpness, but hydration can take a few days or even a few applications if your lips are particularly dry. However, effects from a lip mask can easily last for several days.
If you have dry and chapped lips, adding a lip mask to your beauty routine can be a much easier way of dealing with it than having to carry lip balm everywhere you go. Lip masks are effective, convenient, and deliver long-lasting hydration to your lips, helping to heal and prevent chapping. They are easy to use and apply and should be part of a beauty routine that includes lip scrubs and, of course, your favorite lip color.
