The hydration synergy of hydrangenol from hydrangea petals, 100%-purity PDRN from salmon roe and 8D hyaluronic acid. A three-step mechanism — opening the skin's moisture pathways (hydrangenol), filling them (hyaluronic acid) and regenerating damaged barrier cells (PDRN) — restores the skin's ability to keep itself hydrated.
Adding water does little when the barrier is loose — it simply evaporates. Hydran PDRN combines hydrangenol to draw moisture in, 8D hyaluronic acid to fill every layer and PDRN to stack moisture veils, locking hydration in so it cannot escape.
A hydrangea-petal ingredient that raises the skin's own water-holding capacity, so it no longer dries out easily.
100%-purity PDRN raises moisture density between loosened skin cells and forms a dense moisturizing film.
Eight molecular weights of hyaluronic acid work layer by layer, from ultra-low to high, forming a three-dimensional moisture network.
Improves the skin's own moisture retention so it resists drying out. Gently calms the irritants that cause water loss and holds moisture firmly inside.
Highly skin-compatible, it raises moisture density between dry, loosened cells and forms a dense film on the surface so supplied moisture cannot evaporate.
Eight hyaluronic acids from ultra-low to high molecular weight act step by step: instantly filling deep dryness while stacking protective veils on the surface.
Clinical tests completed for firmness, wrinkles, collagen content, density and antioxidant activity.

To prevent oxidation, the key actives are sealed inside hydrangea petals. As you rub, the petals break into nano-particles smaller than a pore, carrying moisture deep into the skin and absorbing cleanly without stickiness.
At their freshest until the moment of use
Break down smaller than a pore to penetrate deeply
Refreshing deep hydration with no stickiness
Use after toner, morning and evening.
One or two pumps onto your palm.
Rub lightly in your palm until the petals dissolve.
Start with dry areas, spread over the face and pat to finish.
