Remedies for Blisters on Lips

Kalpana Kumari
Blister on lips, also known as cold sores, are caused by infection of the herpes simplex virus. Here, we cover a few home remedies to get rid of this condition.
A blister is an area on the skin where the uppermost skin layer (epidermis) separates from the middle layer (dermis). A clear fluid called serum develops and fills this gap. It is followed by the regrowth of epidermis from beneath.
Formation of blister is actually one of the results of some sort of defensive activity carried on by your body against a harmful foreign body. Thus, there can be several factors that may cause blisters on lips.


If you experience recurrent episodes of cold sores, you may witness its onset while going through a stage of weak immunity. A virus, called herpes zoster, resides in the nerve nodes of such individuals. It stays till it finds the conditions in the body favorable for its growth and reproduction.
The virus travels through the nerve to the skin (here lips) and causes the formation of blisters. Such a condition develops when your immune system gets weakened. It may occur when you go through a stage of physical or emotional stress.
The other reasons behind the formation of blisters include injury to the mouth, excessive exposure to sunlight, extreme cold or hot temperatures, and hormonal imbalance occurring during menstruation and pregnancy. They may also occur by skin trauma caused by shaving, microbial infection, respiratory illnesses, and food allergies.

Home Remedies

The following home remedies will help you get rid of the sores on the lips:

► Take an ice cube and rub it on the affected lip. If you do it as soon as you feel the tingling or burning sensation on your lip, you may prevent the growth of the blister.
► Aloe vera has antiseptic, antibacterial, anti-inflammatory, and antifungal properties. Application of its pulp is the best known cure for blisters caused by a wide range of factors.
► Try to lead a stress free life as much as possible. You may practice yoga and meditation to relieve yourself from mental strain.
► Protect your lips from overexposure to sunlight. To be on the safer side, wear a lip balm containing zinc oxide or some other compound that may act as a sunscreen.

► Place a moistened tea bag on the blister. Tea contains tannin, which is an alkaloid that is known to ease pain.
► Use a soft bristle brush for cleaning your teeth. This will minimize the chances of any trauma to lip that might occur during teeth brushing.

Many people ask for 'how to hide a fever blister on your lip'. The answer is to apply a little amount of lipstick on the blister with the help of a lip brush. This will hide its appearance to some extent. If you do not wear lipstick, you can mix a small amount of facial mask with lip balm, and apply on it. This will again work towards hiding its appearance.
Make sure that you keep the lip well moisturized all the time. Otherwise, dryness of lips may make the appearance of blisters even worse. Try out the suggested home remedies to speed up the healing process. Monitor the condition for a couple of days. If you do not notice satisfactory improvement, consult a health care professional.
