Emollients are moisturising treatments applied directly to the skin. Often used to treat dry skin conditions such as eczema, they reduce water loss from skin by covering it with a protective film.
The everyday use of soaps, shampoos and shower gels can remove your skin’s surface layer of natural oils. This can make your skin dry and can further aggravate long-term skin conditions such as eczema.
Soap substitutes are one type of emollient that can be used instead of soap for handwashing and bathing, and aqueous cream can be used as a substitute for shaving foam. However, aqueous cream must always be washed and rinsed off the skin.
Emollients are also available as bath oils and moisturising creams and ointments.
They are available in tubes, tubs and larger pump dispensers and can either be bought over the counter from your pharmacy or prescribed by your GP. If you or your child need to use an emollient regularly, it is a good idea to keep some at home or at school in small pots or tubes.
How they help
Emollients work by:
- helping skin to retain water
- moisturising dry skin
- easing itching
- reducing scaling
- softening cracks
- allowing other creams and ointments to enter the skin
How to use them
Mix a small amount of soap substitute in the palm of your hand (about a half to one teaspoonful) with a little warm water, and spread it over damp or dry skin. Rinse and pat the skin dry, but do not rub.
If you are using a soap substitute and you are also using anti-psoriasis treatment, apply the soap substitute first. Allow 30 minutes after using a soap substitute before applying the anti-psoriasis treatment.
Some people may have a reaction to aqueous cream when it is used as an emollient. For this reason, it is recommended only as a soap substitute and not as a leave-on emollient.
However, if your skin stings after using aqueous cream and does not settle down after rinsing, speak to your GP or pharmacist about an alternative soap substitute.
Emollient bath additives can be added to lukewarm bathwater to help prevent the loss of moisture from your skin. They can make surfaces slippery, so always use a non-slip mat and be careful when getting yourself or your child out of the bath.
Some bath oils include an antiseptic, which can help prevent infection. However, these products should only be used occasionally unless the infection is recurrent or widespread.
Never use more than the recommended amount of bath additive. If the concentration is too high, it may cause skin irritation, particularly when used with antiseptic bath oils.
Creams and ointments
Emollient creams are less greasy than emollient ointments. They are easy to spread, absorb easily into the skin and are good for use during the daytime. Emollient creams can be used on weeping eczema.
Emollient ointments are most suitable for very dry, thick skin and are not suitable for use on weeping eczema. Find one that is best suited to your or your child.
Occasionally, emollient creams may sting when they are first applied to very dry skin. This usually settles down after a few days of treatment. If it persists, it may be due to a reaction to a preservative in the cream. If this occurs, talk to your GP or pharmacist about possible alternative emollients, such an emollient ointment.
Emollients can be used to replace lost moisture whenever your skin feels dry or tight. They are very safe and you can't overuse them because they don't get absorbed through your skin into your body.
You may need to try a variety of different emollients before you find one that is best suited to you or your child. For example, you may decide to use a cream-based emollient during the day and an ointment base at night.
When to apply them
Emollients can be applied as often as recommended by the manufacturer to keep the skin well moisturised and in good condition.
It's especially important to regularly apply an emollient to your hands, because they are exposed to the elements more than any other part of your body.
You may also want to use emollients after washing your hands, having a bath or taking a shower.
Emollients are best applied when the skin is moist and should ideally be applied to the skin at least three or four times a day.
Whether you are prone to dry skin or not, it's a good idea to use an emollient cream or ointment after washing or bathing. This is when your skin is most in need of moisture. The emollient should be applied as soon as you have patted your skin dry to ensure it is properly absorbed.
Treating skin conditions
Some emollients contain specially medicated formulas that can be used to treat skin conditions such as:
eczema: a long-term skin condition that causes the skin to become reddened, dry, itchy and cracked
psoriasis: a long-term skin condition that causes red, flaky patches of skin covered with silvery scales
If you have a dry skin condition such as eczema or psoriasis, use a medicated emollient even when your skin feels better, to help prevent patches of inflammation and flare-ups. Dry skin is more prone to infection.

Possible reactions to emollients
Possible reactions to emollients can include:
Last updated: 14 January 2014
Irritant reactions: these include an overheating, burning sensation or stinging. It is usually caused by a reaction to a certain ingredient contained in the cream or lotion. If the stinging is painful and continues, try a different emollient.
Folliculitis: some emollients can occasionally cause hair follicles to become blocked and inflamed (folliculitis) and cause boils.
Facial rashes: some facial emollients can cause rashes on the face and can aggravate acne.
