[Qingtan B&A Dermatology Department] Hyaluronic acid

Scientific name of hyaluronic acidHyaluronic acid (HA), is a polysaccharide substance originally contained in human skin and soft tissue. One molecule can lock 500 - 1000 times its own water. Cross-linked hyaluronic acid for medical beauty injection is highly compatible, metabolically soluble, and is the core material for filling, shaping and replenishing water.

It is divided into three categories according to degree of crosslinking and molecular weight, and its uses are completely differentiated:

1. Small molecule hyaluronic acid (non-crosslinked/low-crosslinked)

The texture is thin and soft, with strong penetration and no strong support

1. Purpose: Moisturizing the whole face, improving dry lines, rough and dull lines, and shallow and fine lines on the neck.
2. Maintenance: 1 - 3 months, regular re-ups are required

2. Medium molecular weight hyaluronic acid (moderately cross-linked)

Moderate soft and soft, taking into account filling softness and support

1. Uses: apple muscle, temple, tear groove, decree line, lying silkworm, lip enrichment, soft tissue depression
2. Maintenance: 6 - 12 months

3. Macromolecule hyaluronic acid (highly crosslinked)

High hardness, strong shaping support, and difficult to spread and shift

1. Uses: rhinoplasty, chin pad, eyebrow arch, mandibular ligament support, deep contour shaping
2. Maintenance: 10 - 18 months, which is the main injection material for contour improvement
