Dryness and sensitivity are both linked to a breakdown in the skin’s barrier function. Skin that has good barrier function will prevent moisture from leaving the skin too rapidly and will also keep toxins and opportunistic microbes out. Low Molecular Mass Hyaluronic Acid boosts moisturisation and has an anti-ageing effect. Key Actives: Prebiotics – Inulin and α-glucanoligosaccharides have been shown to improve roughness and redness and reduce irritation in sensitive skin. Prebiotics favour the growth of beneficial microbes. Probiotics – Nourish Moisturiser uses a probiotic extract of probiotic Lactobacillus species. This extract has the ability to improve the populations of beneficial microbes on skin. The overall effect is to boost skin condition and plump the skin by improving moisturisation and T-junction activity.
