3.5 Treatment – dry skin
Emollients are the cornerstone of treatment for all dry skin conditions. These soften, smooth and rehydrate the skin, helping to reduce the signs and symptoms of dry skin as well as making the skin less itchy, moister and more flexible, preventing skin cracking. When used in the right quantity and frequency, they often reduce the need for topical steroids.xxi
There are several different types of emollients, in the form of gels, lotions, creams, ointments, bath and shower oils, and soap substitutes. Simple emollients put a fine moisture-retaining layer of non-physiologic lipid or oil, such as petrolatum or mineral oil, over the skin surface and thereby reduce water loss from the stratum corneum (the upper skin layer). More advanced emollient products contain additional ingredients, including humectants such as urea and glycerol, which attract and hold water in the stratum corneum.xxii
In 2018, the NHS Clinical Commissioners (an independent collective voice of CCGs) recommended that treatment should not normally be offered or prescribed in primary care for mildly dry skin.xxiii Further guidance to CCGs from them was published in 2019 including a short section on the use of bath additives and shower preparations for dry skin and pruritic skin conditions.xxiv As a consequence, many CCGs unfortunately (and incorrectly) took this as guidance to discourage emollient prescribing generally, with the result that many patients with dry skin conditions have found it increasingly difficult to access emollient treatment on prescription, causing their skin condition and its psychological impact to deteriorate.
There is no good evidence from controlled trials to support the use of one emollient over another and prescribing emollients should never be based purely on cost alone. Patient preference is crucial along with clinical assessment, but other factors to be consideredxxv include;
- Severity of skin dryness
- Cosmetic acceptability and ease of use (it is often necessary to try a range of emollients
before a patient finds the best treatment for them)
- Using creams and lotions on red and inflamed areas of skin and ointments for dry skin that is not inflamed.
- Prescribing in suitable quantities – NICE recommends 250g/week for children with atopic eczemaxxvi and that should be doubled in adults. Emollients should be prescribed in 500g tubs and pumps to ensure patients adhere to guidance on the quantity of emollient required per application, and the frequency with which it is applied.
- All emollients are combustible, but those containing paraffin are highly flammable and patients must be warned about this risk.xxvii
Patients should be instructed on how to apply their emollient correctly, putting it onto the
skin and rubbing it in following the same direction as the skin hair. The best time to apply it is after washing, bathing or showering when the skin is warm and moist allowing moisture to be trapped in the skin. Compliance with regular emollient use is far more likely if a patient fully understands the benefits of emollients and has been shown how to apply them properly.xxviiii As a result, always take time to demonstrate to your patient how to apply emollients correctly.
Treatment – mental health
The 2020 APPGS report found that counselling and cognitive behavioural therapy (CBT) were the most common psychological therapies provided to inquiry respondents with skin conditions, and approximately a fifth received medications, such as anti-depressants.
When assessing a person with a suspected common mental health disorder, consider using a validated measure relevant to the disorder or problem being assessed, for example, the 9-item Patient Health Questionnaire (PHQ-9), the Hospital Anxiety and Depression Scale (HADS) or the 7-item Generalized Anxiety Disorder scale (GAD-7) to inform the assessment and support the evaluation of any intervention.
When offering treatment for a common mental health disorder or making a referral, follow a stepped-care approach, usually offering or referring for the least intrusive, most effective intervention first such as cognitive behavioural therapy.
If a person with a skin condition presents with symptoms of anxiety and depression, assess the nature and extent of the symptoms, and if they have depression accompanied by symptoms of anxiety, the first priority should usually be to treat the depressive disorder, in line with the NICE guideline on depression. If they have an anxiety disorder and comorbid depression or depressive symptoms, consult the NICE guidelines for the relevant anxiety disorder and consider treating the anxiety disorder first. If both anxiety and depressive symptoms are present (with no formal diagnosis) and these are associated with functional impairment, discuss with the person the symptoms to treat first and the choice of intervention.xxix
