What’s the difference between the 12-minute, 20-minute, and 24-minute LDM modes in Ilsan? 4 key differences

When looking into skin care, you may come across LDM modes divided by time, such as 12 minutes, 20 minutes, and 24 minutes. Many people wonder whether the only difference is “just the time,” or whether there are actually differences in how they are structured.

LDM is known as an ultrasound-based device, and the way it is performed and the scope of care may differ depending on the application time. In this post, we will organize what differences there are among the LDM 12-minute, 20-minute, and 24-minute modes.

1. Structural differences among the Ilsan LDM 12-minute, 20-minute, and 24-minute modes

LDM may vary in frequency switching methods and application time depending on the set program. Here, 12 minutes, 20 minutes, and 24 minutes often refer not simply to the amount of time spent, but to the program composition time.

1.1 12-minute mode

This is made up of a relatively short time and may be applied to care focused on a specific area. For example, it is often used in situations where a partial approach is needed, such as trouble-prone areas or localized swelling management.

1.2 20-minute mode

This is often applied to care targeting the entire face. Its coverage is broader than the 12-minute mode, and as more time is available, it may be structured to focus on improving the overall condition of the skin.

1.3 24-minute mode

This is a slightly expanded version compared with the 20-minute mode, and may be operated by including the neck area in addition to the face or by dividing the program into stages. However, the actual structure may vary by clinic.

2. Differences in the scope of application among the Ilsan LDM 12-minute, 20-minute, and 24-minute modes

If you look at what differences there are among the LDM 12-minute, 20-minute, and 24-minute modes, differences may appear in the scope of application.

• 12 minutes: focused on localized areas

• 20 minutes: focused on the entire face

• 24 minutes: may include the face + additional areas

These differences may lead to different choices depending on the condition and the purpose of care. However, a longer time does not necessarily mean a difference in results.

3. Differences in composition among the Ilsan LDM 12-minute, 20-minute, and 24-minute modes

LDM is known as a method that alternates low and high frequencies. Depending on the time, this transition stage may differ.

• 12 minutes: mainly basic stages

• 20 minutes: repeated or expanded stages

• 24 minutes: the number of stages may be more subdivided

However, this varies depending on the device settings and operating method, so even with the same “24 minutes,” the composition may differ by clinic.

4. Differences in planning among the Ilsan LDM 12-minute, 20-minute, and 24-minute modes

The differences among the LDM 12-minute, 20-minute, and 24-minute modes are also considered when setting up a care plan.

4.1 Time efficiency

If short care time is needed, the 12-minute mode may be chosen.

4.2 Adjustment according to skin condition

The time may be adjusted depending on dryness, sensitivity, and whether there are skin troubles.

4.3 Whether it is combined with other care

If it is performed together with another laser or program, the LDM time may also be adjusted by considering the total time required.

📌 LDM 12-minute · 20-minute · 24-minute mode comparison

Category	LDM 12 minutes	LDM 20 minutes	LDM 24 minutes
Care time	About 12 minutes	About 20 minutes	About 24 minutes
Application scope	Focused on localized areas	Focused on the entire face	May include the face + additional areas
Program composition	Mainly basic stages	Repeated or expanded stages	Stage subdivision possible
When used	When care for a specific area is needed	Overall condition care	When expanding stages or scope
Selection 기준	Time efficiency focus	Balanced care	When considering expanded care scope

※ The actual composition may vary.

The LDM 12-minute, 20-minute, and 24-minute modes are often not simply structures where “the time is longer,” but ones in which differences occur in the application scope and stage composition.

The 12-minute mode is often used to focus on a specific area within a relatively short time, while the 20-minute mode may be operated in a way that balances the entire face. The 24-minute mode may be structured with more subdivided stages or by expanding the scope to include the neck area.

However, a longer time does not necessarily mean a difference in results. A common approach is to choose the appropriate time based on skin condition, whether other treatments are being combined, and the overall care plan.

In the end, it is best to understand the choice among the LDM 12-minute, 20-minute, and 24-minute modes as a process of considering both the current condition and the purpose together.
