A water-based humectant serum combining three molecular weights of hyaluronic acid with a crosspolymer and panthenol. Surface and deeper-layer hydration in one step. Apply to damp skin and seal with moisturiser — on bare dry skin, HA can pull water outward and make things worse.

What's actually doing the work
Hyaluronic Acid
Sodium Hyaluronate / HA / Multi-Weight HA
Acid
A glycosaminoglycan naturally present throughout the body, holding up to 1000x its weight in water. The most powerful naturally occurring humectant. Multi-weight HA (high, medium and low molecular weight) delivers hydration at different skin depths. Production declines significantly with age.
Panthenol
Vitamin B5 / Pro-Vitamin B5 / D-Panthenol
Vitamin
Converts to pantothenic acid on absorption. Functions as a powerful humectant, anti-inflammatory, and wound-healing accelerant promoting keratinocyte proliferation. Essential for damaged-skin recovery. Suitable for any skin type, including post-procedure and reactive skin.
