Collection: Skin Barrier Repair

Possible signs include tightness, roughness, flaking, increased sensitivity, persistent stinging and redness. These symptoms are not unique to barrier disruption and can also occur with eczema, contact dermatitis, rosacea or infection. If symptoms are severe, widespread, painful or persistent, ask a pharmacist, GP or dermatologist rather than self-diagnosing.

Common factors include harsh cleansing, very hot water, frequent scrubbing, using several exfoliating acids together and increasing retinol too quickly. Cold weather, low humidity, sun exposure and some medical treatments can also contribute. The first step is to stop or reduce the likely trigger, not to layer more active products over irritated skin.

Ceramides and other skin-similar lipids support the outer layer; humectants such as glycerin and hyaluronic acid improve hydration; and emollients such as squalane smooth roughness. Occlusive ingredients help reduce water loss. A simple, well-tolerated formula is usually more useful than a long ingredient list when the skin is reactive.

Mild irritation may improve within several days after the trigger is removed, while more significant dryness or sensitivity can take a few weeks. The exact time depends on the cause and whether irritation continues. If the skin worsens, repeatedly flares or shows little improvement, seek professional advice.

If the skin is burning, persistently stinging, peeling or inflamed, pause optional retinol, acids and scrubs. Use a gentle cleanser, moisturiser and sunscreen until comfort returns. Reintroduce only one active at a time and at a lower frequency. Follow any prescribed treatment according to the prescriber's advice rather than stopping it without guidance.

An occlusive ointment can reduce water loss and help some very dry skin, but “slugging” is not suitable for everyone. Heavy layers may feel uncomfortable on oily or acne-prone skin and can increase irritation if applied over strong active products. Patch test and use a small amount over a simple moisturiser rather than sealing in an irritating routine.

No. Gentle barrier-supporting products may improve comfort alongside an appropriate care plan, but they do not diagnose or treat eczema, rosacea, allergy or infection. Use medical treatments as directed and ask a professional before adding strong actives. Persistent rashes, eye symptoms, weeping, crusting or swelling need assessment.
