A consultant dermatologist breaks down the role of the skin barrier and explains how ceramides support it by boosting hydration and calming irritation. Ceramides play a key role in restoring the skin’s barrier and promoting recovery, says Dr Joseph Toh, consultant dermatologist at Parkway MediCentre Dermatology Clinic.

This was true for a 32-year-old patient of Dr Joseph Toh, who used harsh exfoliants daily in an attempt to improve her complexion. But the excessive cleansing did more harm than good – she soon developed severe redness, stinging and flaking, recalled the consultant dermatologist at Parkway MediCentre Dermatology Clinic.skin barrier is the outermost layer of your skin , made up of skin cells and lipids. It acts as a shield, locking in moisture and keeping harmful substances out. When intact, skin stays smooth, hydrated and resilient. When compromised, it can become dry, irritated and inflamed., several environmental and genetic factors can weaken the skin barrier. Singapore’s high humidity and heat can encourage the body to produce more sweat, which. “Ongoing exposure to these elements without adequate moisturisation can weaken the skin barrier, especially in those with existing sensitivities,” said Dr Toh.Eczema, or atopic dermatitis, is one example. Mutations in the filaggrin gene – present in up to 10 per cent of individuals – impair skin hydration and structure, making skin more vulnerable to environmental stressors. Dr Toh shared that scratching itchy, eczema-affected skin further disrupts the barrier, creating a vicious cycle of damage and irritation. “A compromised skin barrier increases trans-epidermal water loss and lets irritants and allergens in more easily, worsening conditions like eczema, acne and rosacea,” he elaborated. “This can reduce quality of life and cause persistent discomfort.” When damage is caused by eczema, ageing or excessive cleansing, the skin barrier may struggle to produce ceramides, said Dr Toh. Ceramides are waxy lipid compounds that make up about If you think of skin cells as bricks, ceramides are the mortar holding them together, he explained. “They prevent moisture loss and protect against environmental damage. Without adequate ceramides, the barrier becomes leaky and vulnerable.”, making it harder for the skin barrier to repair itself. “Topical products supply ceramides to replenish what the skin lacks, accelerating healing. They integrate into the lipid matrix, helping to seal gaps, reduce trans-epidermal water loss and soothe inflammation,” said Dr Toh. The Ceradan range follows the 3:1:1 ratio of ceramides, cholesterol and fatty acids to support skin repair. Dr Toh recommends that people with sensitive or eczema-prone skin avoid long showers and harsh soaps, and choose creams that mimic the skin’s natural 3:1:1 lipid ratio for effective skin barrier repair. He recalled a patient in his 40s who eased monthly eczema flares by switching from a fragranced shower gel to a gentler, non-scented alternative and applying a ceramide-based moisturiser after every shower. “This small change helped improve his symptoms,” he noted. Ceramide-based products come in various forms – from cleansers to moisturisers and barrier creams. The Ceradan range, for example, includes options for daily use and more intensive care, all formulated to be both effective and gentle on skin. For best results, Dr Toh suggests applying ceramide creams at least three times a day, especially after bathing or handwashing. Ideally, they should be applied within three minutes of towel-drying to lock in moisture: “Damp skin enhances absorption. Keeping the cream in the fridge can also provide a cooling, anti-itch effect.” While some assume oily skin does not need moisturising, that’s a misconception. “Even oily skin can have an impaired barrier and benefit from lipid-rich moisturisers,” he added. Dr Toh’s other tips include using a humidifier during long hours in air-conditioned environments, showering in cool to lukewarm water, wearing breathable cotton clothing to reduce sweat-induced irritation and managing stress to prevent eczema flares. “Stay hydrated and eat a balanced diet rich in omega-3 fatty acids, with foods like flaxseed or salmon,” he advised. “Don’t fall for the myth that drinking water alone hydrates the skin – real hydration comes from your skin’s natural moisturising factors and topical lipids like ceramides.”We know it's a hassle to switch browsers but we want your experience with CNA to be fast, secure and the best it can possibly be.
