During the summer season, many people want just one thing: to go out into the sun and have some fun.

But, not all people take into account the numerous risks that arise from being exposed to the sun for a long duration—either due to work-related situations or by choice—which often leads to the formation of sun blister on lips.

It is a factor that is particularly valid for people who have a very fair skin as they have an increased risk of getting sunburnt. Lips, just like the other parts of your body can also be affected by the sunburn, with overexposure to the sun rays leading to the formation of the blisters.

People who spend time out in the sun on a regular basis tend to have some sunscreen with them at all times.

But, as they apply it to their bodies, they do not take into account the fact that their lips are also exposed, and require some protection.

If your skin is sensitive, this means that your lips are also sensitive, and you will need to acquire a lip balm with a high sun protection factor (SPF).

How to get rid of sun blisters on lips

Let your lips be

Tiny, unbroken lip blisters will normally heal on their own with time. However, you can speed up your healing process by ensuring that you limit the total duration that you are exposed to the sun.

You should also avoid touching the blisters while ensuring that this area remains dry at all times. Do not pop the swelling unless it is incredibly huge, as this can lead to an infection, which will require an even longer time for it to heal.

Keep the blisters clean

Given that the burning has occurred on your lips, it could become a challenge trying to bandage the affected area.

  • As such, it will be important to make sure that your blisters remain clean at all times.
  • You can use germ-killing wipes to clean the area, though you will need to check the ingredients that are present in the wipes.
  • Some wipes cannot be used in the mouth, as they contain ingredients that can be harmful were they to be swallowed.

To ensure that the blisters will not be irritated further, try to avoid lotions and petroleum-based products that contain licodaine.

Ease your pain

Almost all burns are likely to cause a painful swelling of your skin. You can reduce this and reduce the discomfort that you are experiencing by taking ibuprofen or aspirin.

Additionally, using corticosteroids or cooling gels will assist in moisturizing your skin, as well as easing your pain. Stay away from moisturizers that contain alcohol if you would like to prevent any further irritation.

Apply an antibiotic

You can use an antibiotic cream to make the healing process much easier. Prior to using the cream, make sure that your blisters are clean and completely dry. The advantage of using these creams is that they ensure that your blisters will not become infected.

An antibiotic cream that contains iodine or alcohol should be avoided as it will delay the healing process.

Drain the blisters

If you have massive sun blisters, there is a possibility that they could pop on their own, but if this does not happen, you have the option of popping them to drain out the fluids.

You will need to use a large sterilized needle to pop the blister. Once it is drained, make sure to clean the lips as well as dry them.

Water Blister on Lip

A water blister on lip starts to form when your skin layers separate leading to the collection of fluids. The fluid, which appears water-like, is the body’s creation of a defensive serum between your top skin layer and the tissues that have been damaged.

The water blister on lip can also be caused by a reaction to a skin product that you are currently using, friction, antibiotics, or biting the inner parts of your mouth.

Often, it is best to leave it as it is, but, if it becomes a nuisance, you can always use a sterilized small needle to pop it open, and then clean the area using rubbing alcohol.

Causes of water blisters

A water blister as mentioned above is mainly caused by a low-grade trauma occurring on the inner part of your lip.

The trauma may be in the form of an accidental bite, a reaction to certain medication, or damage that may have come about after eating rough textured food. If a water blister becomes infected, it is likely to develop into a canker sore.


Skin found on your inner lip tends to be very sensitive to trauma. Additionally, the saliva that is present in your oral cavity maintains a humid environment at all times, and this makes lesions to develop at a faster rate in this region. Damage caused to the deeper layers of your skin leads to the emergence of the tiny blisters.

On development, the blisters are accompanied by pain as well as a low-grade inflammation. To avoid any further complications, it will be important to make sure that the blister remains intact.

But, there is always the likelihood that your water blister could be drained accidentally while you are chewing.

At this point, if you do not apply an antibiotic or antiseptic, the chances of the lesions becoming infected increase two-fold.

Additionally, the local inflammation that is present in these lesions tends to be more dramatic, which may lead to the collection of pus. You should also note that canker sores are naturally more painful as compared to the water blisters.

A recurrence of the blister can be attributed to factors such as:

  • Hormonal imbalances
  • High body temperatures
  • Fatigue
  • Fever
  • Dental surgery
  • Friction
  • Biting the inner part of your mouth
  • Reaction to a particular product

How long do they last?

Before they can heal completely, they can last for between two and three weeks. But, the good news is that there are certain home remedies that you can use to hasten the healing process of your blister.

If you happen to have a very weak immune system, you may be required to seek medical attention. You may also have to visit a physician if:

  1. You experience frequent recurrent outbreaks
  2. The symptoms have become severe
  3. This infection begins to affect your eyesight.

Fever blisters and cold sores are mainly caused by HSV-1 (the herpes simplex virus). The HSV-1 virus is transmitted from one person to the next through skin contact or by saliva (by using the same glass as an infected person or directly).

White blisters on lips

Upon infection, cold sores start to appear on the lips in the form of tiny clustered blisters. Eight to ten people have this virus, which is responsible for causing cold sores, according to the Center for Disease Control. In many cases, an individual gets infected with the virus before their tenth birthday.

After the initial infection, the HSV-1 virus tends to remain inactive (dormant) in your facial nerves. But, for some, it will from time to time become active, and when these happen, a lip blister appears. The virus can be activated by a fever or a cold.

What causes fever blisters on lips?

But, it is possible to reduce the severity and number of your blister outbreaks by establishing what causes them, and then avoiding the triggers altogether.

Just as is the case with genital herpes, oral herpes can also be spread from one person to the next even the sores are not visible or present.

It is, however possible to reduce the risk of transmission by ensuring that you wash your hands when you have cold sores, as they are normally transmitted via touch. In the case of a cold sore, it can only be transmitted when the sore is visible. However, the herpes virus may be spread even when there are no sores or symptoms.

What causes a milk blister on baby’s lips?

The main cause of these white milk blisters is the vigorous sucking that is associated with the breastfeeding task.

There are babies that are born with these blisters, especially in a case where the baby sucked on its thumb while still in the womb.

Newborns perform the repetitive sucking of movement for several hours in one day, which then causes the calluses or the blisters to appear on the upper lips of the baby.

Often, the milk blisters on baby’s lips are more likely to appear during the initial months of the baby’s life, according to information published by the Ruch Clinic.

While they are in this stage, the babies will be sucking after every two to three hours, which generates sucking related friction. The friction then causes the blisters to start developing.

In some cases, the blisters could go away after a feeding session, while in other cases they could last for months before going away. As the baby starts adjusting to baby feeding, the blisters should disappear after a few weeks.

Treatment and remedies for milk blisters on lips

As a mother, you should therefore not allow these tiny and harmless white milk blisters to impede your efforts to breastfeed your baby properly.

Even though the repetitive sucking may cause the blisters to remain on the lips, keep in mind that they are only unsightly, but they are not harmful in any way.

Milk blisters on baby’s lips are more common in babies that have been breastfed, but they can also appear in a child that is being bottle-fed. A baby applies the same sucking motion they use when breastfeeding to obtain milk from the feeding bottle.

But, in bottles, the milk flow tends to be faster, which means that less vigorous sucking is needed, thereby reducing the chances of your child getting the lip blisters. If a bottle-fed baby develops such a blister, no treatment will be required, as it will similarly go away on its own with time.
