I know 'must-have' is a overused term, but this one product that I have had to repurchase and keep as part of my everyday routine. I use after shaving , which gives an instant cooling relief. After a few minutes the 'gel/essence' absorbs into the skin and there is a slight tightening (always nice to feel something 'working') and then It's time for my moisturiser. An all year round product - great for extra moisture in colder harsher months but equally soothing and refreshing in warmer climates.
