Overview

Intense hydration. Immediate calm.

Skin can be intensely dehydrated and reactive at the same time. Tightness, visible redness and fine dehydration lines often appear together — and hydration alone doesn't always address the full picture.

Āio is formulated for both. A concentrated, multi-pathway hydration system saturates thirsty skin with moisture, while 2% ectoin and our 5% Calm Recovery Complex target dehydration stress and visible reactivity.

Our Adaptive Hydration Complex combines fast-acting humectants, osmolytes, natural moisturising factors and long-lasting water binders to deliver intensive hydration and help skin retain moisture.

Alongside it, clinically studied ectoin, madecassoside and targeted Aotearoa marine and botanical bioactives work to support barrier resilience and reduce the appearance of stressed, reactive skin.

Lightweight, cushioned and fragrance-free, Āio leaves skin intensely hydrated, visibly plumper, smoother and calmer-looking — without heaviness or greasiness.

Concentrated hydration. Targeted calm. One powerful serum.

INTENSE, MULTI-PATHWAY HYDRATION
Our 17%+ Adaptive Hydration Complex combines fast-acting humectants, osmolytes and long-lasting water binders to saturate moisture-depleted skin and support sustained hydration.

RAPID CALMING. VISIBLY LESS REDNESS.
Our 5% Calm Recovery Complex combines Aotearoa marine and botanical bioactives with complementary madecassoside to target visible redness and the signs of skin reactivity.

2% ECTOIN DEHYDRATION DEFENCE
A clinically studied extremolyte provides osmoprotective support, helping maintain moisture-barrier function and improve resilience against dehydration stress.

PLUMPS SKIN. SMOOTHS DEHYDRATION LINES.
Glycerin, polyglutamic acid and natural moisturising factor components replenish moisture, improve suppleness and reduce the appearance of fine dehydration lines.

CONCENTRATED HYDRATION. LIGHTWEIGHT FINISH.
A cushioned, fragrance-free, non-greasy serum that delivers intensive moisture while layering easily with other treatments and moisturisers.

For skin that's thirsty, sensitive or quick to react.

Āio is particularly well suited to:

  • Dehydrated skin experiencing persistent tightness, rough texture or fine dehydration lines.
  • Sensitive, reactive skin and eczema-prone skin prone to visible redness, irritation, intense dryness and environmental stress.
  • Skin flare ups. This serum can be applied multiple times a day, with rapid calming within as little as 15 minutes.
  • Combination and blemish-prone skin needing intensive hydration without heavy oils or an occlusive finish.
  • Mature or changing skin experiencing increased dehydration, sensitivity, irritation or reactivity. 
  • Skin using intensive active treatments that needs additional hydration and barrier support.

An advanced daily treatment for skin that needs concentrated moisture and targeted calming care — without unnecessary weight or fragrance.

Need more barrier support? Pair with Tīeki Biomimetic Restore Crème to replenish essential barrier lipids and help reduce moisture loss.

Apply generously to lips for hydration and comfort. Use at night for an overnight mask.

Inside the formula

The breakdown

Multi-pathway hydration. Long-lasting moisture retention.

A concentrated system of fast-acting humectants, osmolytes, natural moisturising factors and water-binding polymers designed to hydrate skin through complementary mechanisms.

Glycerin + Propanediol — Powerful humectants that attract water into the upper skin layers for immediate moisture replenishment.

1% Saccharide Isomerate — A skin-affinitive carbohydrate complex that binds to the outer skin layers to support sustained hydration. Ingredient research at this concentration demonstrated hydration benefits lasting up to 72 hours following a 28-day application period.

Betaine + NMF Components — Sodium PCA, sodium lactate and other moisture-binding ingredients work alongside the skin's natural moisturising system to help maintain water balance.

Polyglutamic Acid — A high-molecular-weight water binder that forms a hydrating film, helping smooth skin texture and visibly plump dehydration lines.

Panthenol + Hydrolysed Oat Protein — Complementary moisturising and skin-conditioning actives that support hydration and skin suppleness.

Together, these ingredients deliver multiple pathways to intensive hydration, helping replenish moisture immediately and maintain it over time.

2% Ectoin


Advanced osmoprotection. Stronger hydration resilience.

Ectoin is an extremolyte — a protective molecule originally identified in microorganisms adapted to survive extreme environmental conditions.

Its distinctive interactions with water help stabilise the hydration environment surrounding biological structures, making it particularly valuable in formulations targeting dehydration and environmental stress.

Used at a substantial 2% concentration, ectoin is one of Āio's primary treatment actives.

Clinical research on a formulation containing 2% ectoin supports its moisturising and skin-conditioning benefits, including improvements in skin surface and elasticity parameters.

In Āio, ectoin works alongside the Adaptive Hydration Complex to support moisture balance, barrier resilience and smoother, more hydrated-looking skin.



Rapid calming technology. Targeted redness reduction.

A specialised Aotearoa marine and botanical complex combined with purified Centella-derived madecassoside to address visible redness and signs of skin reactivity.

Our 5% Calm Recovery Complex brings together red seaweed, native mamaku, kawakawa and mānuka honey in a targeted bioactive system.

The marine polysaccharides and botanical compounds contribute complementary moisturising and skin-conditioning properties, while supplier research at a 5% use level demonstrates rapid calming activity and improvements in measured redness parameters.

Madecassoside, a highly purified active from Centella asiatica, adds another targeted mechanism. Studied for its soothing and barrier-supporting properties, it complements the botanical complex for skin experiencing environmental stress and visible reactivity.

Together, these actives bring a dedicated calming dimension to Āio — going beyond hydration alone to address the appearance of stressed, reactive skin.
