PH5 x Hyaluronic Acid


The world's first hydraknit™ technology infused with Hyaluronic Acid to moisturise your body while you sleep.

Upon launching the brand in 2014, PH5 immediately set out to propose new possibilities of what knitwear can be by combining whimsical design-focused ideas with tech-driven production capabilities. When searching for their next innovation PH5 turned their sights to skincare. Bringing Hyaluronic acid to clothing. In fact, a PH of 5 is the optimal PH of our skin, this pH level will ensure proper cell turnover, hydration, and protective barrier. It was in our DNA, literally.

Key Facts

Infused with Hyaluronic acid

Utilizing newly developed technology, hyaluronic acid microcapsules are attached to the pores of the yarn to be transfered to the skin

Equivalent to 3500 face masks

The effective content of hyaluronic acid in the fabric is equivalent to 3500 masks after 8 hours of use.

Good for 40 Washes

This fabric has been lab tested with hyaluronic acid being present after 40 washes.

Responsibly sourced

Made from certified Ecovero Viscose, the fibers are derived from sustainable wood and pulp, coming from certified and controlled sources and generates up to 50% lower emissions and water impact compared to generic Viscose. Ecovero Viscose is soft, breathable and absorbent.

Knitted in the PH5 factory

We work hand in hand with our computer engineers and technicians to code and pattern each design. This process creates stretchy movable pieces made with zero-waste engineering.

Why Hyaluronic Acid?

  • Hyaluronic acid is a substance that occurs naturally within our own bodies, reducing as we age.
  • Hyaluronic acid is one of the reasons that young skin appears plump and hydrated.
  • Roughly half of the hyaluronic acid in your body is present in your skin, where it binds to water to help retain moisture (1).
  • When applied to the surface of the skin, hyaluronic acid serums can reduce wrinkles, redness and dermatitis (2, 3).
