HA

HYDRATION SCIENCE

Multi-Weight Hyaluronic Acid.

Hydration that goes deeper.

Hyaluronic Acid is a naturally occurring molecule found in every cell of your body — but skin loses it rapidly with age and dehydration. Unlike single-weight HA serums, our formula uses multi-molecular weight Sodium Hyaluronate to hydrate at the surface, the mid-dermis, and deep in the dermal layer simultaneously. The result: real plumping, real smoothing, real all-day moisture.

0% Plumper, more hydrated skin
0% More radiant, glowing look
0% Hydrated feel all day long
0x Hydration depths targeted
01
PATHWAY 01

Surface Hydration

High-MW Sodium Hyaluronate

HA → Epidermis → Instant Plump

High molecular weight HA forms a moisture-retaining film at the skin surface — immediately smoothing and plumping the outer layer for visible results from the first application.

02
PATHWAY 02

Deep Dermal Moisture

Low-MW Sodium Hyaluronate Crosspolymer

HA Crosspolymer → Dermis → Lasting Hydration

Smaller HA molecules penetrate deeper into the dermal layer, holding up to 1000x their weight in water to deliver sustained, all-day hydration from within.

Two molecular weights. One serum. Total hydration.

YOUR RITUAL

How to Use.

01
STEP 01 · CLEANSE
🧴

Cleanse

Cleanse your face with the Helloskin Cleanser, rinse with lukewarm water, and gently pat skin dry. Apply to slightly damp skin for maximum absorption.

02
STEP 02 · APPLY
💧

Apply

Apply a small amount of the Hyaluronic Acid Serum and gently massage into face and neck in circular motions until fully absorbed. Use AM and PM.

03
STEP 03 · MOISTURISE

Moisturise

Seal in the hydration with the Helloskin Face Moisturiser. In the AM, finish with SPF 30+. The moisturiser locks HA into the skin for all-day plumping.

EXPECTED RESULTS

Days 1–3

Instantly softer skin. Improved moisture levels visible from first use. Dull, tight skin starts to feel more comfortable and supple.

Week 2

Noticeable plumping of fine lines. Skin texture smoother and more even. Complexion looks visibly more radiant and hydrated throughout the day.

Weeks 3–4

Sustained all-day hydration. Fine lines visibly softened. Skin barrier strengthened — less sensitivity, better moisture retention and a healthy, glowing complexion.

💡 Pro Tips

Apply to slightly damp skin — HA needs water present to bind to

Layer under your Vitamin C serum in the AM for an antioxidant + hydration stack

Ideal as a base before any active (retinol, AHA, BHA) — buffers and soothes

Safe for use during pregnancy — no restricted actives
