Skin care hero dermatologists love and still swear by. There is a good chance a jar of Vaseline is sitting in your bathroom cabinet right now, and dermatologists say that is a very good thing. Invented in 1870, the petroleum jelly has become so widely used that it now qualifies as a proprietary eponym, joining the ranks of Kleenex and Q tips as a brand name that doubles as the generic term for the product itself.

Dermatologists, beauty experts, mothers and nail artists all point to the same reason for its staying power: it works, and it costs almost nothing.
Experts call it one of the best deals at the drugstore
Board certified dermatologists note that Vaseline can be applied nearly anywhere on the body, from the face to the feet, and is especially helpful on rough spots like elbows, knees and cuticles. It is also considered an occlusive product, meaning it forms a barrier on the skin that locks in moisture rather than adding hydration itself, which makes it particularly effective right after a shower or bath.
Many families made it part of their nightly routine
For generations, Vaseline has been a fixture in households across the country, especially in Black families, where mothers often coated their children’s faces and bodies with it after bath time as a matter of course. Some dermatologists recall the ritual clearly, describing childhoods where a heavy handed application left their skin shiny well before bed.
The K-beauty trend known as slugging brought new attention
In recent years, a skin care method called slugging has surged in popularity online. The practice involves applying a thin layer of Vaseline as the final step of a nighttime routine to seal in serums and moisturizers underneath. Fans say it leaves skin soft and hydrated by morning, though for many families it is nothing new, since versions of the technique have quietly existed for decades.
Dermatologists do offer a caution or two. The product itself should not cause breakouts, but it can leave skin feeling heavy, which makes it less appealing for those with oily or acne prone complexions. Experts also recommend against layering it over active ingredients like retinol or hydroxy acids, since sealing those in can increase irritation.
Everyday uses go well beyond the face
Dermatologists list a wide range of practical uses, including treating minor cuts and scrapes, soothing chapped skin, easing diaper rash and preventing chafing. Some nail artists also swear by an overnight hand treatment, applying a generous layer of the jelly before slipping on cotton gloves to lock in moisture while sleeping.
The product is also considered gentle enough for use on skin prone to discoloration after cuts, scrapes or breakouts, since it can help wounds heal with less resulting pigmentation change.
A favorite for lips and finishing beauty looks
Because lips lack oil glands of their own, they tend to dry out easily, which is one reason Vaseline remains a go to lip treatment. It is also used to calm peeling or discoloration that can follow chemical peels or retinoid treatments, and some beauty fans use a small amount to groom eyebrows or add shine to lashes for a simple, no fuss finishing touch.
It also plays a role in dermatology offices
Vaseline is not just a home remedy. Many dermatologists use it in clinical settings, including on wound, biopsy and surgical sites, often paired with a protective dressing. That approach reflects newer thinking in wound care, which suggests keeping a healing area moist helps new skin cells move across it more easily than leaving the wound exposed to air, an older method that can lead to scabbing and slower healing.
A few precautions worth remembering
Despite its reputation, Vaseline is not meant for every situation. It should not be applied to a fresh sunburn, since it can trap heat against already damaged skin. Anyone with very oily or acne prone skin who is not currently working with a dermatologist is generally encouraged to check with one before adding it to a routine.
Even so, dermatologists describe it as remarkably low risk, rarely triggering irritation or allergic reactions, which helps explain why a product invented more than 150 years ago is still recommended in exam rooms and passed down in bathroom cabinets today.
