Personal & Family Household Products Guides

What Personal & Family Household Products covers

This section covers personal and family care products used around the home: petroleum jelly and Vaseline products, baby care items, and similar everyday preparations.

Petroleum jelly dominates the questions, and it is a good example of a product whose reputation has drifted well beyond what it actually does. It is an occlusive — it forms a barrier that slows water loss from skin. That is genuinely useful: it protects chapped lips, cracked heels and minor grazes, and it reduces friction where skin rubs. Dermatologists use it routinely for exactly these purposes.

What it does not do is moisturise in the sense people usually mean. It does not add water to skin; it holds in what is already there. This is why it works best applied to skin that is already slightly damp, and why applying it to dry skin can feel like it is doing less than expected.

Two limits are worth knowing because they cause real problems. It is oil-based, so it degrades latex — meaning it must not be used with condoms or latex gloves. And it should not go on a burn, an infected wound or a deep wound, where sealing the surface traps heat and bacteria rather than helping.

How the guides in this section differ

Occlusive, humectant or emollient. Three ways a skin product works. Occlusives such as petroleum jelly form a barrier. Humectants such as glycerin draw water into the skin. Emollients smooth and soften. Many products combine them, and knowing which one you have explains why it behaves as it does.

Petroleum jelly or a branded variant. Products in a range differ in added ingredients — fragrance, sunscreen, additional emollients — while sharing the same base. Where a variant adds something meaningful, the guide says so.

Adult or infant use. Baby products are formulated for thinner, more permeable skin, generally without fragrance. Not everything suitable for an adult suits an infant.

Cosmetic or medical. A product that protects chapped skin is not a treatment for a skin condition. Persistent problems need a diagnosis rather than a thicker barrier.

Safety, accuracy and next-step checks

These guides follow product labels and are informational rather than medical advice.

Points worth carrying:

Do not use oil-based products with latex. Petroleum jelly degrades latex, causing condoms and latex gloves to fail. Use a water-based product where latex is involved.
Not for burns or infected wounds. Sealing the surface traps heat and bacteria. Burns need cooling under running water and, beyond the most minor, medical attention.
Do not put petroleum jelly inside the nose regularly. Repeated use of oil-based products in the nostrils has been associated with a rare form of pneumonia when small amounts are inhaled over time, particularly in children and older adults. Saline products are the safer option for nasal dryness.
Apply to slightly damp skin. As an occlusive it works by holding moisture in, so it is most effective straight after washing.
Patch test anything new, especially on a child or on sensitive or broken skin.
Check fragrance on baby products. Infant skin is thinner and more permeable, and fragrance is a common irritant.
Keep out of reach. Small children swallow cosmetic products readily; contact a doctor or the Poisons Information Helpline if that happens.
Persistent skin problems need a doctor. Eczema, ongoing cracking or a non-healing wound deserves assessment — see our skin and wound care guides.

A reasonable way to think about products in this section is that they protect rather than treat. A barrier product helps skin that is intact but stressed — chapped, chafed, dry from cold or wind. It is doing something real and useful there. What it cannot do is resolve an underlying condition, clear an infection or heal a wound that is not healing on its own. When a skin problem persists past a couple of weeks, spreads, or looks infected, the right next step is a pharmacist or doctor rather than a thicker layer.

Frequently asked questions

Does petroleum jelly moisturise skin? Not directly. It forms a barrier that slows water loss, which is why it works best on skin that is already damp. It does not add moisture.

Can I use it with condoms? No. It is oil-based and degrades latex, causing failure. Use a water-based lubricant.

Is it safe on a burn? No. It traps heat and bacteria. Cool a minor burn under running water; anything more than minor needs medical attention.

Can I put it in my nose for dryness? It is better avoided. Repeated use of oil-based products in the nose carries a small risk of inhalation-related pneumonia. Saline sprays or gels are the safer choice.

Is it suitable for babies? It is widely used for nappy-area protection, but choose fragrance-free products and check with a clinic nurse or doctor for a persistent rash rather than continuing to treat it at home.
