SK-II Facial Treatment Essence is a nutrient-packed liquid that’s become a cult-favorite product of skincare junkies with a very long resume of benefits. The essence not only works to reduce the appearance of fine lines and dark spots, but it also improves skin’s overall radiance, tone and texture. Sound too good to be true? Well here’s why it works. This miracle water amplifies your skin’s natural rejuvenation process thanks to Pitera—a super ingredient that contains vitamins, amino acids and minerals all of which enhance the skin. There’s actually 90% Pitera in every bottle of SK-II Facial Treatment Essence, which is why it’s so effective. The formula is so potent.
