When choosing a clinic for Argenesis, first confirm whether a physician experienced in facial vasculature will perform the injection, and how complications will be managed if they occur[1][2]. Hyaluronic acid can be reversed with a degrading enzyme, but Argenesis has different ingredients, so it is safer not to assume the same approach will work[3][4].
Why is clinic selection so important for Argenesis?
Argenesis is a gel filler made from agarose derived from seaweed.[4] It differs in composition from hyaluronic acid, and it has been reported that it does not use a cross-linking agent to bond the ingredients together[4].
Hyaluronic acid can be broken down by an enzyme called hyaluronidase.[3] This enzyme is designed to degrade hyaluronic acid. It is safer not to assume that Argenesis, which has a different composition, can be dissolved in the same way.
Some experts suggest that physicians inexperienced in injection should first use hyaluronic acid, which can be reversed and dissolved, and only move to longer-lasting fillers after gaining experience. The more difficult a filler is to reverse, the more a physician's experience becomes critical.[2] Reversibility becomes increasingly important with experience.
What should you verify about the injecting physician?
First, whether they have thorough knowledge of facial blood vessel anatomy. Vascular occlusion is the most serious complication of injection, and knowledge of facial vasculature is thought to reduce this risk.[1].
Guidelines from Japanese medical societies note that reports exist of hyaluronic acid injection accidentally entering blood vessels, causing skin necrosis or blindness, and they urge caution.[5].
It has also been pointed out that procedures performed by people without medical credentials or proper training may be linked to increased complications.[6].
How should you verify preparedness for complications?
Vascular complications can have smaller lasting effects if detected early and managed promptly.[1].
For hyaluronic acid injection, it is required that a dissolving enzyme be kept on hand and ready to use immediately, and that staff receive training in its application[7]Algeness does not rely on this enzyme, so ask in advance what to do if vascular complications are suspected.
There is expert guidance that you should be told to contact the clinic immediately if after treatment you notice firmness, eye pain, double vision, or reduced visibility.[8].
What are the characteristics of Algeness — how much explanation will you receive?
The quality of an explanation becomes clear in whether the provider discusses even what is not yet known.
Reports indicate that Algeness has low water affinity and does not spread easily after injection.[4]At a concentration of 3.5%, it is reported to last up to approximately 18 months.[4]Reports also note that it has properties that make precise placement in the target area easier.[9].
There is a report of its use in 700 patients.[10]However, this report is from a limited number of facilities, and no direct comparative studies with hyaluronic acid were found.
Reports also note that in injections performed by non-medical personnel, many patients received treatment without knowing the risks.[11]Whether risk explanation is specific can also be a criterion for choosing.
How do you decide between Algeness and hyaluronic acid?
If you are uncertain, comparing three points makes it easier to organize. The first is whether you want to dissolve it and return to the original state if you dislike the shape. If reversibility is a priority, hyaluronic acid is better suited.[2][3].
The second is where you want to inject it. The third is whether you have experienced firmness or swelling from previous injections. These latter two can only be determined after examining your face.
What you should confirm during the consultation
From the article alone, you cannot decide whether Algeness suits your face or whether hyaluronic acid would be better.
At the consultation, confirm the area where you want injection, your desired changes, the types of previous injections, and what will be done if vascular complications or firmness occur.
