A fortifying serum that calms reactive skin before your moisturiser
Isispharma Sensylia Fortifying Hydrating Serum is a hydrating serum for sensitive, reactive skin, designed to reinforce the skin barrier and calm the tightness or discomfort that often comes with sensitivity. It's meant to be layered under a Sensylia cream for extra comfort on the most reactive days.
The texture
A light, fluid serum that absorbs quickly, leaving skin feeling hydrated rather than coated.
Who it suits
- Reactive skin that feels tight or uncomfortable often
- Anyone wanting an extra hydration step under their cream
- Skin sensitised by weather, stress or new products
- Normal to dry sensitive skin
Worth knowing before you buy: on very reactive days, patch test on the inner arm first if trying this serum for the first time.
