Yellow soft paraffin

How it works

It acts as an occlusive emollient, forming a lipid layer over the skin that reduces transepidermal water loss and helps maintain skin hydration and barrier function.

Prescribing in practice

• Paraffin-based emollients are flammable; warn patients that dressings, clothing and bedding in contact with the product can ignite readily near naked flames, cigarettes or heat sources.
• Liberal and frequent application is generally appropriate, and the greasy base may not suit all patients or sites.
• Smooth onto the skin in the direction of hair growth as described in current prescribing references.

Monitoring

Review skin condition and tolerability, adjusting choice of emollient if the product is cosmetically unacceptable or poorly tolerated.

Counselling the patient

• Keep away from naked flames and do not smoke near treated skin, clothing or bedding.
• Apply as often as needed, particularly after washing, to keep the skin moisturised.
• Smooth it on gently in the direction the hair grows rather than rubbing in.

Evidence & guidelines

The MHRA has highlighted the fire risk associated with paraffin-based and paraffin-free emollients, advising patients about flammability of soaked fabrics.
