As you age, you may notice something different every time you look in the mirror. Your skin may no longer feel as firm as it used to, it may seem slightly sagged, and your pores may appear enlarged. These changes are natural, but it is still hard not to feel concerned about them.
These days, there are many ways to improve these concerns without needles. Among them, a method that uses two types of heat energy simultaneously has been receiving attention because it can work on deeper layers while helping reduce surface irritation.
Today, we will carefully go over how this method works and who it may be suitable for.

The process in which two types of heat energy work simultaneously
This care method is structured to deliver two types of heat energy—monopolar and bipolar—at the same time. Monopolar energy sends energy to deeper layers, while bipolar energy focuses on managing relatively shallow layers.
When the two are used together, heat is delivered three-dimensionally from the surface to deeper layers, helping improve the appearance of firmness. With the addition of high-output 400 W energy, stimulation can be provided in a short period of time.
However, stronger heat can also raise concerns about irritation. For this reason, this method is used together with a cooling system that can be adjusted across five levels.
The surface is quickly cooled by spraying an eco-friendly gas, while the system is designed to deliver the heat energy only into deeper areas. This means that even with a noninvasive structure that does not use needles, you may expect more in-depth care.

When results may be noticeable and recommended intervals
Some people notice a difference immediately after receiving care, but more significant changes gradually appear over time. The process by which the heat-stimulated layers produce their own elastic fibers often begins in earnest after approximately 2–3 weeks.
After about a month, you may expect a more refined appearance of creases or the impression that your pores look smaller. These changes may last for up to one year, so there is no need to receive care frequently.
In general, repeating the care once every six months to one year is common. However, recovery speed and lifestyle habits vary from person to person. Some people may receive it somewhat more frequently, while others may choose longer intervals, so it is important to adjust the schedule while checking your individual condition.

Suitable for these individuals
This method may be considered by people who are concerned that their skin is no longer as firm as it used to be or who feel that it has generally become sagged. In particular, it may be helpful for those who have developed creases around areas that frequently move with facial expressions, such as the eyes, forehead, or mouth.
It may also be worth considering for people who are concerned that their pores appear enlarged or that their skin surface looks rough. In addition to naturally occurring age-related changes, it may also be considered when the skin has been affected by factors such as the external environment or ultraviolet rays and needs recovery.
This method also features enhanced cooling, which may help reduce the burden during care. Please note that this may make it a more comfortable option for people with sensitive skin texture.

Things to keep in mind in daily life after care
There are just a few things to pay attention to afterward. First, it is best to avoid rubbing or otherwise irritating the treated area with your hands.
Unnecessary irritation during the recovery process of the heat-treated layers may affect the results. It is also recommended that you avoid alcohol for about one week. Avoiding smoking can also help with recovery.
In addition, avoid hot environments such as saunas or bathhouses for the time being, and it is advisable to refrain from strenuous exercise for about one week. Finally, apply moisturizer and sunscreen thoroughly. Protecting the surface is more important than usual after care.
We hope this information helps you maintain healthy skin by carefully checking whether this method suits your concerns and condition and by paying attention to aftercare as well. Thank you.
