What it is used for

  • Dry skin
  • Eczema and dermatitis
  • Psoriasis
  • Sensitive, easily irritated skin
  • Maintaining the skin barrier between flares

How it works

Emollients soften, smooth and hydrate the skin and form a protective layer that reduces water loss, easing dryness, itching and cracking.

How it is taken

Available as lotions, creams, ointments and as wash and bath products that replace soap. Apply generously and often to the skin, smoothing it in the direction of hair growth, and use the soap-substitute forms for washing if advised. Use as often as needed; reapply after washing and follow any guidance from your clinician.

No doses here on purpose. The right strength and schedule depend on you — only a doctor or pharmacist should set them. Always follow your prescription and the label.

Common side effects

  • Occasional mild stinging on very inflamed or broken skin
  • A greasy feeling with thicker ointments

Serious effects — get help

  • Signs of an allergic or irritant reaction such as a worsening rash, swelling or difficulty breathing (uncommon)

If a reaction is severe — for example trouble breathing, swelling of the face or throat, or collapse — go to the nearest emergency room now or call your local emergency number. Do not wait for an online consultation.

Interactions to watch

  • When using an emollient and a steroid or other treatment together, leave time between them as your clinician advises
  • Paraffin-based emollients on dressings, clothing or bedding are a fire hazard near naked flames or smoking

Who should take care

  • Be aware paraffin-containing emollients can make fabrics more flammable; keep away from naked flames and avoid smoking
  • Apply with clean hands or a clean spoon to avoid contaminating tubs
  • If a product stings or irritates, ask your pharmacist about a different formulation

Frequently asked questions

How often can I use a moisturizer?
Emollients can be applied as often as needed, often several times a day, especially after washing, to keep the skin barrier hydrated.
Cream or ointment — which is better?
Ointments are greasier and hold moisture longer for very dry skin; creams are lighter for everyday or daytime use. Choose what suits your skin and routine.
Is there really a fire risk?
Yes. Paraffin-based emollients soaked into fabric can catch fire more easily, so keep away from flames and do not smoke while using them.
Can I use it with my steroid cream?
Yes, but apply them at different times as your clinician advises so each works properly; emollients are the mainstay between flares.
Is Emollients safe to take?
For most people it is safe when taken exactly as a doctor or pharmacist advises and as printed on the label. Tell your clinician about your other medicines and health conditions, and seek urgent care for any serious reaction.
