Our Optimal SKin-Pro Serum is an intensely nourishing, revitalising serum that helps to replenish and strengthen skin’s natural moisture barrier so that even sensitive skin feels nurtured and healthy-looking.Have you tried ESPA’s Optimal Skin-Pro Serum yet?#ESPA #ESPASkincare #faceserum #skincare #serum #naturalingredients #skincareroutine
