Your skin barrier is doing more work than you realise. Every single day, it fights off pollutants, UV radiation, harsh cleansers, temperature changes, and lifestyle stressors — all while keeping moisture locked in. When it starts to fail, the consequences show up fast: redness, dryness, sensitivity, breakouts, and accelerated ageing.
Understanding what’s happening at a cellular level is the first step to choosing the right active ingredients.
The outermost layer of your skin — the stratum corneum — functions like a brick wall. Skin cells (corneocytes) are the bricks, and a matrix of lipids including ceramides, cholesterol, and fatty acids form the mortar. When this structure is intact, water stays in and irritants stay out.
Compromised skin barrier function means this structure has broken down. The result is elevated Trans-Epidermal Water Loss (TEWL) — water escaping through the skin faster than it should — leaving skin dehydrated, reactive, and vulnerable.
Common causes include:
This is where ingredients like CloverCell® come in. Developed from sustainably farmed Irish red clover (Trifolium pratense), CloverCell® has been clinically evaluated for its ability to support skin barrier protection. In independent testing using validated in-vitro models, it demonstrated measurable benefits for compromised and sensitive skin types.
Unlike many botanical actives that are simply assumed to work based on traditional use, CloverCell® is backed by laboratory data — the kind of evidence that supports credible claims on finished skincare products.
