REN Clean Skincare‘s Evercalm™ Overnight Recovery Balm uses enzymatically activated oils (sourced from olive, almond, borage, and linseed) to nourish and moisturize skin. Sensitive skin types have a weak protective barrier and get more damaged than other skin types during the day, so this balm works at night when cell turnover can double, which is the best time to feed and help the skin.
