The dry air, warm heater and very hot showers over winter gave me very sensitive skin for the first time, due to ageing making my skin less resilient. I needed a product to soothe, protect and rebuild my skin barrier. Tried other products and everything was stinging and not helping at all. Ordered this trial kit along with the barrier repair cream and my skin is fixed in a week. I have had sensitivity and barrier damage before due to overuse of actives, never have I found anything that repaired my skin so quickly, with no stinging or irritation whatsoever. Highly recommend. I will buy full sizes of these products for next winter.
