Product description

Hera’s “Signia Refining Water Essence” is a skin-repairing essence with texture-refining and skin-illuminating properties. The essence is designed to awaken the skin’s inner strength, helping to lay the groundwork for bright, energised skin from the very first step.

Hera’s NEW “Signia Refining Water Essence” helps repair 10 key signs of skin aging from the very first step.

The answer is not force, but a change in pace

Significant skin changes start right from the first step.

  • Skin moisture: +98.9% immediately after a single use1
  • Skin barrier: +21.5% immediately after a single use1
  • Inner elasticity: +22.6% one hour after a single use1

White Camellia EXO™

Skin responds to Hera’s “Signia Refining Water Essence”, infused with White Camellia EXO™, from the very first application.

The key ingredient behind repair-focused anti-aging: White Camellia EXO™:

  • Skin-firming ingredients
  • Exosomes
  • NAD+

Inspired by white camelia, which is known to remain intact for seven days after the flower falls, White Camellia EXO™ was developed from Amorepacific’s 90 years of camellia research as the signature ingredient of Hera’s Signia line.

Prism Repair

White Camellia EXO™ helps restore the skin’s youthful vitality through 3-layer Prism Repair.

  • The ingredient reawakens dormant skin.
  • The ingredient has been shown to enhance skin elasticity up to 2.5 times2 compared to peptides.
  • The ingredient has been shown to strengthen the skin’s natural protective barrier up to 3.4 times2 compared to ceramides.

[2] These claims are based on in vitro test results comparing performance with the company’s in-house raw materials.
