Twenty-three

Twenty-three pairs, written into every cell you have. The rose keeps its own version of the same order, setting each petal at an angle it never had to learn. Hwasoo-23 begins there: not adding something to the skin, but returning it to what it already knows.

SIGNATURE ACTIVE

Rose Placenta Extract

Harvested at the biological crest of the rose’s life cycle, when cellular activity is at its peak, this rare botanical extract concentrates the rose’s innate capacity for growth, repair, and resilience.

Clinically studied, rose placenta supports epidermal growth factor (EGF) activity to encourage skin regeneration, tissue repair, improved vessel density, and recovery from environmental stress.

By activating the NRF2 antioxidant pathway, rose placenta protects against oxidative stress and premature ageing while supporting collagen integrity and dermal structure.

  • Enhances firmness and elasticity through collagen support
  • Brightens and refines skin texture, restoring natural radiance
