Product Advantage

1

Highly effective moisturizing and water lock

Molecular weight 1-1.8 million Daltons, can form a breathable film on the skin surface, with strong water lock ability (1g HA can absorb 500cc of water).

2

Effect

Blocks ultraviolet rays, dust and bacteria invasion, and strengthens the skin barrier.

3

Safe and non-irritating

Non-cytotoxic, passed the medical grade raw material master file filing (M2025008-000), suitable for any skin type.

4

Synergistic skin care effect

Promote collagen elasticity, anti-wrinkle and anti-aging; combined with low molecular weight HA, it can penetrate deeply to achieve the dual effect of ""surface water lock + internal moisturizing"".

Dissolution method

Standard process:

Slowly sprinkle HA powder into stirring deionized water (25-30℃)

Stirring speed: 400-600rpm

Dissolution time: 2-4 hours

Acceleration scheme:

Pre-dispersion in glycerol (1:5 ratio) can be shortened to 1 hour

Use vortex agitator to improve efficiency

FAQ

Q1: What is the difference with oligomeric hyaluronic acid?

A: Core differences:
Characteristics High molecular weight HA (this product) Oligomeric HA (≤50kDa)
Moisturizing duration 8-12 hours 2-4 hours
Transdermal absorption Not absorbed (film forming) Can penetrate the dermis
Touch Slightly sticky Refreshing
Q2: Is it normal to have drawing after dissolution?

A: It is a characteristic of high molecular weight HA, which can be improved by:
① Adding 0.1% disodium EDTA
② Using a spiral stirring paddle
Q3: Can it be used for injection-grade products?

A: A specific medical grade model must be selected (molecular weight must be accurately controlled by ±5%)
Q4: How to compound with collagen?

A: Golden ratio:
HA 0.1% + collagen 0.5%
Addition order: dissolve HA first, then add collagen
Q5: How to store after opening the bottle?

A: Recommended solution:
Package into sterile vials
Seal with nitrogen
Store at -20℃ for 2 years
