The Difference between Monophasic Hyaluronic Acid And Biphasic Hyaluronic Acid

Monophasic hyaluronic acid has a higher degree of cross-linking and a more stable structure, which usually lasts for 12-18 months. Biphasic hyaluronic acid, on the other hand, lasts for a relatively short time, usually 6-12 months. This means that monophasic hyaluronic acid has a longer-lasting shaping effect. However, the specific choice of hyaluronic acid depends on individual needs and the professional advice of the doctor.

The higher the degree of cross-linking of monophasic hyaluronic acid, the tighter the connection between its molecules, which brings the following effects:

Stronger stability and durability

The high degree of cross-linking slows down the decomposition of hyaluronic acid in the body, and the filling effect lasts longer, usually for 12-18 months.

Better shaping effect

The stable structure reduces deformation, which is suitable for shaping and contour modification, and the effect is more natural and full.

Higher viscoelasticity

Makes the touch firmer after injection, suitable for filling deep tissues.

Biphasic hyaluronic acid is commonly used in the following main scenarios due to its unique structural characteristics:

Filling deep depressions

Biphasic hyaluronic acid particles are dispersed in non-cross-linked hyaluronic acid gel, which has a relatively solid texture and strong support. It is suitable for filling deep facial wrinkles and depressions, such as nasolabial folds and tear grooves.

Shaping and contour sculpting

Due to its good support and shaping ability, biphasic hyaluronic acid is suitable for facial contour shaping, such as rhinoplasty and chin shaping.

Parts that require faster absorption and adjustment

Biphasic hyaluronic acid is absorbed slightly faster than single phase, which makes it easier for doctors to adjust the injection dose and effect according to the recovery situation.

Large area filling

Because it contains a relatively large amount of gel and particles mixed, it can be used for large area filling needs in thicker skin areas.
