Abstract

A system and a method for delivering a dermal filler are illustrated. The system includes a dermal filler, wherein the dermal filler includes an injectable filler, wherein the injectable filler further includes at least a hyaluronic acid and at least a raw material, and a syringe configured to deliver the dermal filler. The method includes obtaining an injectable filler, wherein the injectable filler further comprises at least a hyaluronic acid, modifying the injectable filler by diluting the injectable filler using a raw material, and delivering the modified injectable filler by injecting the modified injectable filler into a patient using a syringe.

Claims (18)

1 . A method for delivering a dermal filler, the method comprising:

obtaining an injectable filler comprising transplant fat of a patient, wherein the injectable filler further comprises at least a hyaluronic acid;

modifying the injectable filler, wherein modifying the injectable filler comprises diluting the injectable filler using a raw material; and

delivering the modified injectable filler, wherein delivering the modified injectable filler comprises injecting the modified injectable filler under an eye of the patient using a syringe, wherein:

the modified injectable filler is resized in accordance with a size of the syringe such that the modified injectable filler passes through a needle of the syringe with an extrusion force; and

diluting the injectable filler comprises diluting the hyaluronic acid to a sufficiently low concentration such that the diluted hyaluronic acid is restrained from adverse pushing against the eye of the patient.

2 . The method of claim 1 , wherein the raw material comprises at least a sugar alcohol.

3 . The method of claim 2 , wherein the sugar alcohol accounts for 0.1 to 20% of a total weight of the dermal filler.

4 . The method of claim 1 , wherein diluting the hyaluronic acid comprises diluting the hyaluronic acid in a physiological buffer.

5 . The method of claim 4 , wherein the physiological buffer further comprises 0.9% sodium chloride.

6 . The method of claim 1 , wherein injecting the modified injectable filler further comprises utilizing a total quantity of 3 mg/ml-30 mg/ml of the hyaluronic acid.

7 . The method of claim 1 , wherein the hyaluronic acid is a crosslinked hyaluronic acid using a crosslinking agent.

8 . The method of claim 1 , wherein obtaining the injectable filler further comprises outputting a composition of the injectable filler, by a computing device, using user data collection as an input correlating user data from the user data collection with at least a sugar alcohol needed to modify the injectable filler.

9 . The method of claim 8 , wherein delivering the modified injectable filler further comprises utilizing the computing device to output the composition of the modified injectable filler by analyzing the user data collection using a composition machine-learning model trained by at least a composition training datum.

10 . The method of claim 1 , wherein the dermal filler further comprises: at least a sugar alcohol.

11 . The method of claim 10 , wherein modifying the injectable filler further comprises adding at least an anesthetic to the injectable filler prior to the dilution.

12 . The method of claim 10 , wherein modifying the injectable filler further comprises adding at least an anesthetic to the injectable filler after the dilution.

13 . The method of claim 1 , wherein the syringe is utilized with a cannula, wherein the cannula comprises a flexible tubing comprising a blunt tip, and wherein the blunt tip is configured to be inserted under a skin of the patient.
