Early lip balms
Since 40 BC, the Egyptians made treatment for lip care, which utilized a mixture of beeswax, olive oil, and animal fat.

United States
In the 1800s, Lydia Maria Child recommended earwax as a treatment for cracked lips in her highly-popular book, The American Frugal Housewife. Child observed that, "Those who are troubled with cracked lips have found this earwax remedy successful when others have failed. It is one of those sorts of cures, which are very likely to be laughed at; but I know of its having produced very beneficial results." The invention of the lip balm was first formally invented in the 1880s by physician Charles Brown Fleet and was given the name "Chapstick".

Notable brands
In 1872, chemist Robert Chesebrough discovered and sampled a new petroleum jelly, initially describing it as a "natural, waxy ingredient, rich in minerals from deep within the earth" which could be used as a solution for skin repair. He then distributed his product under the name "Wonder Jelly" before shortly changing it to "Vaseline".

In the early 1880s, Charles Brown Fleet created Chapstick. However, due to the lack of sales, Fleet sold his formula and rights to Chapstick to John Morton in 1912 for $5, who saw the marketing potential in the brand. After making the purchase, Morton commissioned Frank Wright, Jr. to create a design for the logo of Chapstick for $15 in 1936. In 1972, Chapstick tubes concealing hidden microphones were used during the Watergate scandal.

In 1937, Alfred Woelbing created Carmex to treat cold sores in Milwaukee, though the occurrence of World War 2 would slow the production and sales due to the lack of lanolin. In 1980, Carmex underwent a product change by converting its packaging into squeezable tubes.

In 1973, Bonne Bell created the first flavored lip balm and marketed the company as Lip Smackers. The company would later collaborate on various different-flavored lip balms including Dr. Pepper in 1975, The Wrigley Company in 2004, and The Coca-Cola Company in 2006. Bonne Bell also collaborated with Disney to produce lip balms with various princess characters in 2010.

In 1991, Burt Shavitz and Roxanne Quimby created their first beeswax based lip balm solution through their company, Burt's Bees. In 2020, it was reported that Burt's Bees had used 50 percent of recycled material to package various products and that 100 percent of the products were recyclable.

In 2011, Evolution of Smooth (or commonly known as EOS) created a spherical-shaped lip balm as well as describing its 95% organic ingredients.

Cannabis infused lip balms
With the gradual legalization of cannabis in the United States, some companies have produced lip balms containing doses of THC or CBD oil. In 2018, Ermont Inc., medical marijuana dispensary in Quincy, Massachusetts created the first THC lip balm. The lip balms were infused with a low dosage of THC in order to prevent the occurrence of any psychoactive or related effect, but rather to act as a pain-relieving ingredient. CBD, which is known for its pain relieving and anti-aging properties, is also extracted from cannabis to be used as an ingredient for lip balms. Some cannabis infused lip balms have also included sativa strains in order to enhance concentration and energy. Other cannabis infused lip balms use indica strains, which were reported to provide a solution to anxiety and stress due to the nature and property of THC. Although there are many health related uses of cannabis infused lip balms, there are others purposely meant for recreational purposes. Wax is a type of lip balm composed of hash oil which has the strength of dozens of cannabis joints. Although it can be applied directly on the lips, there are several instances where it can be eaten or smoked using a device.

Causes
According to a report, professor Brad Rohu states that it is natural for the lips to feel dry. The exposure to environments with cold, dry, or windy weather can directly cause the chapping of the lips as well as behaviors such as lip licking or mouth breathing. These factors may directly contribute to an increased amount of lip balm usage. According to dermatologist Amy Derick, those who have expressed dependencies on lip balm have developed a desire of how the lips feel after application. She also mentions that the variety of lip balm flavor may also directly cause lip balm dependency as a person may want to lick their lips to taste the flavor, which may consequentially removes the lip balm coating from the lips. This may also leave saliva on the lips which can dry up and make the lips feel even more dry than it initially was.

Addictive ingredients
Some physicians have suggested that certain types of lip balm can be addictive or contain ingredients that actually cause drying, though, it has been debated by many professionals. Lip balm manufacturers sometimes state in their FAQs that there is nothing addictive in their products or that all ingredients are listed and approved by the FDA. Snopes found the claim that there are substances in Carmex that are irritants necessitating reapplication, such as ground glass, to be false. However, some experts such as Dermatologist Dr. Cynthia Bailey states that some ingredients in lip balm directly causes sensitive lip skin which may lead to addiction. Dermatology professor Marcia Driscoll also adds onto this argument by stating that aroma ingredients found in flavored or scented lip balms have the potential to irritate skin.

Effects on lip barrier
The human lips have an inadequate capability of holding moisture as well as an imperfect lip barrier function. The Journal of the American Academy of Dermatology performed a study in order to determine whether consistent use of lip balm would enhance the overall quality of the lips. The study used 32 female participants within the ages of 20 to 40 years and the participants had mild to moderate dried lips without any history of health-related complications. The participants underwent a procedure in which no lip treatment was provided on the first 3 days, then 2 weeks of consistent lip balm usage, and then a period of no treatment for 3 days. The study determined the quality of the lips based on the physical details and appearance throughout the study. The study showed a direct improvement of the physical details of the lips except for lip cracking during the second week of treatment and after the period of no treatment. The study also showed that hydration of the lips lasted for approximately 8 hours after usage and the lip balm improved the lip barrier function despite discontinued usage. The study concluded that lip balms assist the hydration of the lips which consequentially improves the lip barrier function and the quality.

United States
In 2019, a research report conducted by the Statista Research Department concluded that Chapstick was the leading lip balm brand in the United States with an approximate unit sale of 55.8 million. Carmex was the second leading brand with approximately 35.2 million units sold and Burt's Bees being the third leading brand with approximately 32.3 million units sold.
