Treating dry patches on the face requires a multi-faceted approach focusing on barrier repair and the restoration of the stratum corneum's lipid matrix. The primary clinical recommendation is the use of emollient-rich moisturisers containing physiological lipids such as ceramides, cholesterol, and free fatty acids in a 3:1:1 ratio. This specific ratio has been shown to accelerate barrier recovery and reduce transepidermal water loss (TEWL) significantly [1]. Additionally, clinicians recommend the application of humectants like glycerin or low-molecular-weight hyaluronic acid to damp skin to draw moisture into the epidermal layers before sealing it with an occlusive agent [2].
To effectively resolve persistent patches, it is essential to minimise further barrier disruption by switching to pH-balanced, non-foaming cleansers and temporary cessation of exfoliating acids or retinoids. In the harsh Australian climate, where UV exposure can exacerbate xerosis, incorporating a high-protection SPF 50+ sunscreen with added moisturising factors is crucial to prevent further inflammatory response and cellular damage [3]. If dry patches are accompanied by intense itching or redness, they may indicate subclinical dermatitis, which may require short-term topical anti-inflammatory intervention under medical supervision [4].
Dry patches, clinically referred to as localised xerosis cutis, occur when there is a deficiency in the skin's natural moisturising factors (NMF) and a disruption in the lamellar lipid bilayers. From a biochemical perspective, this leads to an impairment of the desquamation process, where corneocytes fail to shed individually and instead clump together, creating the visible 'patchy' texture [1].
In Australia, environmental stressors such as high UV indices and low humidity levels associated with air conditioning create an osmotic gradient that pulls moisture from the viable epidermis. This 'TEWL' leads to a cytokine-mediated inflammatory cascade, which can further degrade the structural proteins like filaggrin, essential for maintaining the skin's internal hydration and acidic pH [3][5].
For those seeking to support the skin's natural defence against dehydration, our Surface Calm cleanser is formulated with foundational lipids like ceramides and cholesterol to ensure the barrier remains intact during the cleansing process. To further encourage resilience, incorporating a moisturiser like Cellular Crème can help seal in essential moisture with shea butter and hyaluronic acid, providing the rich yet weightless nourishment required to soften persistent dry patches.
FAQ
Can I exfoliate dry patches to make them go away?
Physical scrubbing or harsh chemical exfoliation is often counter-productive for dry patches. While it may temporarily remove visible flakes, it further compromises the already weakened skin barrier, leading to increased inflammation and deeper dehydration [2]. Instead, favour gentle polyhydroxy acids (PHAs) like gluconolactone, which provide mild keratolytic action while acting as humectants [5].
What are the best ingredients for dry patches?
The 'gold standard' ingredients for targeted treatment include petrolatum for occlusion, niacinamide to stimulate endogenous ceramide production, and panthenol (Provitamin B5) for its soothing and wound-healing properties [1][4]. Urea is also highly effective at concentrations below 10%, as it acts as both a humectant and a mild regulator of corneocyte shedding [5].
When should I see a GP or dermatologist about dry patches?
If dry patches are resistant to over-the-counter moisturisers after two weeks, or if they appear as well-defined, silvery-scaled plaques or weeping lesions, professional consultation is necessary. These can be symptoms of conditions like psoriasis, nummular eczema, or actinic keratosis—a pre-cancerous lesion common in Australia that requires clinical monitoring [3][4].
