Regarding the difference between manual injections and machine injections~~~^^

I searched online for information on how the Sonjusarang machine injection, a method used in Rejuran procedures, differs and summarized the differences.

The first thing that caught my eye was Difference in the method of procedure Manual injection is a method where a doctor directly injects medication into the skin one by one using a syringe. It is said that a major advantage is the ability to perform very delicate, customized treatments even on areas with thin, curved skin, such as around the eyes and mouth. On the other hand, mechanical injection is a method that uses electric equipment to precisely inject medication at a consistent depth and amount using multiple needles.

Secondly, Drug loss and embossing marks I found there is a difference. It is said that manual injections deliver medication directly into the dermis layer of the skin, ensuring that the drug is absorbed efficiently without leaking out. Consequently, it is reported that bumpy, embossed marks resembling mosquito bites remain on the skin for a few days immediately after the procedure. On the other hand, mechanical injections use negative pressure to pull the skin in and deliver the medication broadly and evenly, resulting in relatively less embossing that subsides quickly.

Finally, the one that many people are most curious about Pain difference However, it is said that manual injections are quite painful because you can feel the stinging sensation directly as the needle enters and the medication is injected. On the other hand, machine injections pull the skin taut to inject the medication instantaneously, so they are said to be much less painful compared to manual injections.

Those who want to ensure thorough effectiveness without medication loss, even if it causes a little pain, often prefer manual injections. They say they will do it~~~^^
