Chapped lips are a near-universal annoyance, and for generations, many have reached for a familiar standby: petroleum jelly. But is this time-honored remedy actually effective, or could it be doing more harm than good? A growing conversation online is questioning the benefits of lip balms containing petroleum jelly, prompting a closer look at how these products operate and whether it’s time to rethink our lip care routines.
Petroleum jelly, often recognized by the brand name Vaseline, has long been considered a simple, reliable solution for dry, cracked lips. Even as, its primary function isn’t necessarily to *add* moisture, but rather to create a protective barrier. Dermatologists explain that it’s an occlusive, meaning it prevents water loss, allowing the lips to retain their natural hydration. Here’s particularly important as lips lack the protective layer of skin cells found elsewhere on the body, making them prone to dryness.
How Does Petroleum Jelly Work on Lips?
According to Jeremy Fenton, MD, a board-certified dermatologist and medical director at Schweiger Dermatology, petroleum jelly “helps to moisturize in that it allows the skin to retain and replenish its own moisture without battling against the constant transepidermal water loss (TEWL) that occurs without an occlusive.” It also possesses emollient properties, smoothing and softening already dry or cracked lips, adds Ava Shamban, MD, founder of AVA MD. Essentially, petrolatum doesn’t hydrate on its own, but it’s highly effective at locking in existing moisture.
Concerns about the safety of petroleum jelly often stem from its origin as a byproduct of petroleum refining. However, experts like Dr. Shamban assure that products like Vaseline and Aquaphor undergo extensive refining processes to remove potentially harmful impurities. “If you are talking about a brand like Vaseline or Aquaphor sold by the hundreds of millions of tubes, jars, vials, and sticks, it may have an origin as a petroleum-based product, but it has been highly-processed and refined to remove the impurities that would be toxic or unhealthy,” she explained. These refined products are considered hypoallergenic, safe for employ on wounds and even babies, and don’t penetrate beyond the skin’s surface, minimizing systemic absorption.
Is Petroleum Jelly the Best Option?
Despite the safety assurances, some argue that petroleum jelly isn’t a complete solution for severely dry lips. While it excels at preventing moisture loss, it doesn’t actively introduce hydration. To maximize its effectiveness, dermatologists recommend pairing it with a humectant – an ingredient that draws moisture from the air – such as hyaluronic acid or polyglutamic acid (PGA). Applying a humectant first, then sealing it in with petroleum jelly, can provide a more comprehensive approach to lip care.
In fact, David Kim, MD, a board-certified dermatologist and founder of Soho Dermatology, goes so far as to say, “Vaseline Lip Therapy is the best lip balm, period. There is nothing else that works nearly as well to moisturize the lips.” However, he and other experts acknowledge that individual results may vary.
Beyond Petroleum Jelly: Alternative Lip Care Ingredients
While petroleum jelly remains a top recommendation for many dermatologists, other ingredients can also contribute to healthy lips. Drs. Fenton and Kim agree that petrolatum is difficult to surpass, but options exist for those seeking alternatives.
the best lip balm is the one that works for you. If your current routine includes a petroleum jelly-based product and it’s providing relief, there’s no need to discontinue its use. However, understanding how these products function – and considering a combined approach with humectants – can help you achieve optimal lip health, especially during colder, drier months.
As research into skincare continues to evolve, staying informed about the latest recommendations from dermatologists is key to making the best choices for your skin.
