Petroleum jelly is one of the most widely recognised skincare products, often found in bathroom cabinets and recommended for everything from dry lips to cracked heels. For generations, it has been used as a multipurpose moisturiser and protective barrier, but many people in the UK still wonder if it is genuinely good for skin or simply an old-fashioned remedy. Understanding what petroleum jelly does, who it benefits and how it should be used can help you decide whether to make it part of your skincare routine.

What Is Petroleum Jelly and How Does It Work

Petroleum jelly, also known as petrolatum, is a semi-solid mixture derived from refined petroleum. It is an occlusive moisturiser, which means it does not add water to the skin but instead forms a barrier on the surface to lock in existing moisture. By preventing water loss, it helps skin stay hydrated for longer and provides a protective shield against irritants, wind and cold weather. This makes it particularly effective in treating areas prone to dryness.

Benefits of Petroleum Jelly for Skin

One of the main advantages of petroleum jelly is its ability to soften and smooth rough, dry patches. It is widely used for chapped lips, cracked heels, dry elbows and irritated hands, especially during the colder months in the UK when skin naturally loses more moisture. Because it is fragrance-free and generally safe, it is often recommended for sensitive skin and even for babies with nappy rash. Many people also use it to protect minor cuts and scrapes by keeping the area moist, which can help prevent scabbing and promote smoother healing.

Petroleum Jelly and Skin Conditions

For those with eczema or very dry skin, petroleum jelly can be particularly helpful. Its thick, protective layer reduces water loss and helps ease discomfort linked with itching and flaking. Dermatologists often suggest it as part of a basic skincare routine for people with these conditions, though it is important to note that petroleum jelly does not treat the underlying causes of eczema or psoriasis. Instead, it acts as a supportive measure that helps relieve dryness and improve skin comfort.

Is Petroleum Jelly Safe for All Skin Types

In general, petroleum jelly is considered safe for most people and is approved for cosmetic use in the UK. However, it may not suit everyone. For those with oily or acne-prone skin, using petroleum jelly on the face may feel too heavy and could block pores if applied too thickly. It is usually best kept for dry areas of the body rather than as an everyday facial moisturiser. People who prefer plant-based or natural alternatives sometimes avoid it, as it is derived from petroleum, but it remains one of the most reliable and well-tested moisturisers available.

How Petroleum Jelly Compares to Other Moisturisers

Unlike creams and lotions that contain water and active ingredients, petroleum jelly does not hydrate the skin directly or deliver vitamins and nutrients. Instead, its effectiveness lies in its ability to seal in moisture that is already present. This means it can be paired with lighter moisturisers or serums to enhance their benefits. For example, applying a hydrating cream first and then sealing it with petroleum jelly can provide longer-lasting results, especially for those with very dry skin.

Uses of Petroleum Jelly in Everyday Skincare

Petroleum jelly is extremely versatile. Many people use it to soothe dry lips, protect skin from harsh weather, smooth eyebrows, or even create a subtle highlight on cheekbones. It is also popular as an overnight treatment for dry hands or feet, often applied before wearing cotton gloves or socks to boost absorption. Because it is inexpensive and easy to find, it remains a reliable choice for those seeking simple, fuss-free skincare solutions.

When Petroleum Jelly Should Be Avoided

While petroleum jelly has many benefits, there are certain situations where it may not be suitable. It should not be applied to deep wounds, serious burns or infected areas, as sealing the skin in these cases could worsen the problem. People with very oily skin should also use it sparingly, particularly on the face. As with any skincare product, it is worth testing a small patch first if you have very sensitive skin to ensure you do not experience irritation.

Final Thoughts on Petroleum Jelly for Skin

Petroleum jelly is a tried and trusted product that has stood the test of time in skincare. It may not provide advanced anti-ageing or nourishing properties, but it remains one of the most effective ways to lock in moisture, protect the skin and improve comfort in areas prone to dryness. For those who struggle with cracked lips, rough heels or dry patches, it is a reliable and affordable option that can fit easily into daily routines.
