⚡ At a Glance
  • Hydration Power: 2% multi-molecular hyaluronic acid attracts and holds moisture to plump skin
  • Best for: Anyone seeking daily, non-sticky hydration and a dewy skin base
  • Not ideal for: People who prefer fragranced skincare or a matte finish

Multi-molecular hyaluronic acid acts like a sponge to draw moisture into the skin. Lightweight, non-tacky texture leaves a hydrated, dewy base suitable for layering.


Long-lasting Hydration – with 2% multi-molecular hyaluronic acid

Multi-molecular hyaluronic acid attracts large amounts of water and holds onto it, with claims of holding up to 1000 times its weight in water. The formulation draws moisture toward the surface to support skin plumpness and elasticity.

Skin feels plumper and smoother, helping fine lines appear less noticeable and improving overall hydration throughout the day.

Light, Non-tacky Finish – with a fragrance-free, fast-absorbing formula

The serum is designed to glide on and melt into the skin, avoiding tacky residue that can interfere with subsequent layers. Suitability for oily skin is specifically noted, so the texture aims for hydration without greasiness.

Layering with moisturiser and makeup becomes straightforward, with no pilling and a dewy base that looks fresh rather than oily.

Simple Daily Integration – with AM and PM usage guidance

Recommended as the first step after cleansing, a pea-sized amount should be applied to face and neck. Applying to damp skin helps lock in moisture, and following with moisturiser and SPF in the morning completes the routine.

Fits easily into morning and evening routines, helping maintain consistent hydration without adding extra steps.
