It features skincare stars like hyaluronic acid and centella extract to hydrate and soothe the skin. Incorporate it into your evening skincare routine for optimal results. Use it no more than once a week and do not use it with the brand's Reedle Shot 100. A slight tingling sensation upon application is normal. Discontinue use immediately if irritation occurs.
