Kool Beauty Hyal [pre] Cursor Concentrate Serum Bi-phase

Bi-phase Hyaluronic Acid Precursor Serum for Dehydrated Skin

A 20ml two-phase facial serum that pairs a hyaluronic acid precursor water phase with a jojoba-led oil phase, shaken together before each use. Built for thirsty, dehydrated skin that wants a single step doing the work of a hydrating serum and a light facial oil.

Why Choose It?

• Two phases, one bottle: A water phase carrying the hyaluronic acid precursor and an oil phase led by jojoba seed oil recombine on shaking, so one step replaces a separate serum and facial oil.
• Deep, lasting hydration: The hyaluronic acid precursor draws moisture into the skin while humectants help hold it there, leaving skin plumper and more comfortable.
• Soft, cushioned finish: Jojoba seed oil with lightweight slip agents gives a fluid, fast-spreading feel that softens without leaving a heavy film.
• Calming botanical base: Damask rose and cornflower flower waters round out the water phase for a gentle, fresh feel on delicate skin.

Best For

Dehydrated, thirsty skin that wants both water-based hydration and a light oil layer in a single step. Also suited to delicate, comfort-seeking skin looking for a gentle, fragrance-light bi-phase serum.

Use on cleansed skin morning and/or evening. Layer underneath a Kool Beauty hyaluronic acid face cream to seal hydration into the routine.

• Shake the bottle firmly until the two phases combine into a uniform fluid.
• Dispense 2-3 drops onto fingertips.
• Press and smooth over the face and neck on cleansed skin, avoiding the eye area.
• Allow the serum to absorb before following with cream or sunscreen.
• Alternatively, mix 2-3 drops into a daily moisturiser in the palm before applying.

Tips

• The two phases separate again on standing — re-shake before every use to keep the dose consistent.
• Apply to slightly damp skin if you want the water phase to spread more easily.
• If layering with other actives, allow the serum to set before the next step.
