Does lip balm help chapped lips? Here’s what to know

The Truth About Lip Balm: Does It Soothe or Irritate Dry Lips?
Introduction: The Quest for Soft Lips
When the cold winds howl and the indoor air grows dry, many of us reach for a trusty tube of lip balm, hoping it will bring relief to our parched, flaking lips. After all, there’s nothing quite as annoying as the discomfort of dry, cracked lips. But is lip balm the hero we make it out to be? While it may seem like the perfect solution, the answer isn’t as simple as it seems. For some, lip balm can indeed soothe and protect, but for others, it might make the problem worse. In this article, we’ll explore the pros and cons of lip balm, the hidden ingredients that might be causing more harm than good, and what you can do to keep your lips soft and supple, even in the harshest of winters.
How Lip Balm Works: Sealing in Moisture
For most people, lip balm is a reliable ally in the battle against chapped lips. Its primary job is to create a protective barrier on the surface of the lips, locking in moisture and shielding them from external irritants like cold wind and dry air. Dr. Jenna Lester, a dermatologist at UCSF Health, explains that a good lip balm acts as a “barrier for external forces.” This is especially important during the winter months when the combination of icy outdoor air and low-humidity indoor environments can strip your lips of their natural moisture. By sealing in that moisture, lip balm can help keep your lips soft and pillowy, just the way we like them.
But not all lip balms are created equal. While they may work wonders for some, others might find that no matter how much they apply, their lips just keep getting worse. So, what’s going on here? The answer lies in the ingredients.
The Hidden Dangers: When Lip Balm Causes More Harm Than Good
For some people, certain ingredients in lip balm can trigger allergic reactions or irritate sensitive skin. Dr. Caroline Mann, a dermatologist at Washington University School of Medicine in St. Louis, notes that common culprits include fragrances, flavors, and preservatives. These additives might make the product more appealing, but they can also cause stinging and discomfort instead of providing relief. “Those are the people who will say, ‘I tried these things. I thought my lips would get better, but they just keep getting worse and worse,’” Dr. Mann explains.
So, what exactly should you be watching out for? Ingredients like lanolin, a waxy substance derived from sheep’s wool, are found in many moisturizers and can cause allergic reactions in some individuals. Preservatives like formaldehyde and chemical-based sunscreens like oxybenzone are also potential offenders. These ingredients can trigger immune responses, leading to redness, itching, and even more dryness. And here’s the kicker: these reactions can happen at any time, even after using a product for years, and they can linger for months after you stop using it.
Soothing Chapped Lips Without Lip Balm
If you’re one of the unlucky ones whose lips react badly to commercial lip balms, don’t despair. There are plenty of other ways to soothe and protect dry, chapped lips. For starters, consider covering your lips with a scarf when you’re outside. This simple trick can shield your lips from the harsh wind and cold air. Indoors, a humidifier can help combat the dry air that saps moisture from your skin and lips.
Dehydration is another common cause of dry lips, so drinking plenty of water is a simple yet effective solution. However, there’s one habit you should avoid at all costs: lip-licking. While it might provide temporary relief, the enzymes in your saliva can actually dry out your lips even more as the moisture evaporates. If you’ve tried cutting back on lip balm and your lips are still stinging, it might be time to consult a dermatologist. With the right advice, you can navigate the winter months with soft, supple lips.
The Safe Bet: Fragrance-Free, Petroleum-Based Balms
For those with sensitive lips, the safest bet is often a fragrance-free, petroleum-based balm.Petrolatum, a common ingredient in these products, is usually listed on the label as petrolatum. It’s a simple, non-irritating option that provides a protective barrier without any of the problematic additives. While some people might be put off by the idea of using a petroleum-based product, the good news is that it’s generally well-tolerated and effective.
Conclusion: Keep Your Lips Soft and Supple This Winter
While lip balm can be a lifesaver for many, it’s important to remember that it’s not a one-size-fits-all solution. If you find that your lips are persistently dry, irritated, or worsening despite your best efforts, it’s time to take a closer look at the ingredients in your balm and consider alternative strategies. Whether you opt for a fragrance-free, petroleum-based product, cover up with a scarf, or run a humidifier in your home, there are plenty of ways to keep your lips soft and supple, even in the harshest of winters. So, armed with this knowledge, go forth and give your lips the love they deserve.
