Moisturisers and emollients
Emollients and moisturisers can help manage and treat psoriasis when used correctly and can be used liberally and frequently.
Emollients soften and moisturise the skin. They are used to improve dryness and scaling. They have two actions: occlusives provide a layer of oil on the skin to slow water loss which in turn increases moisture, and humectants are substances introduced to the outer most part of the skin to help increase the capacity to seal in water. Some moisturisers contain both occlusives and humectants.
Emollients can help:
- clear scaling which in turn makes it easier to apply other topical treatments
- lubricate and soften psoriasis patches preventing cracking
- soothe and relieve itchiness/irritation
- hydrate the skin
- protect the skin from bacteria
- prevent irritation

Emollients come in various forms such as creams, ointments, lotions, bath oils and soap substitutes. Ointments are suitable for dry, thickened and or brittle skin and are more suitable for night time use. Creams/lotions tend to be less greasy and so are more suitable for day time use. By using both ointments and creams regularly the skin will not dry out. |
Bath oils will help hydrate the skin and will leave a film of oil on the skin surface preventing water loss, bacteria and irritation. The oil will keep the skin soft and help prevent cracking. The use of foaming shower gels and foam baths is not recommended as they can irritate and dry the skin out. It is advisable to have warm baths as opposed to hot baths because warm baths prepare your skin for an emollient. You might like to consider applying a bath oil directly on to your wet skin or on to a sponge. However a 10 minute soak is more beneficial.
Soap substitutes, which do not foam, will not dry the skin or remove the skin’s natural oils – but it is essential that you avoid the use of soap at all times.
Emollients can complement other topical treatments such as topical steroids which can rapidly increase an improvement in your psoriasis.
It is always advisable to seek advice from your doctor/dermatologist – he or she will be able to offer the best treatment for your symptoms.
