A double chin is considered an area that is difficult to address with just one treatment.
Onda lifting uses microwave energy to stimulate both fat and collagen, and is used to manage double chins.
When someone feels that there has been no satisfying change after one treatment, it is often because they have not received enough sessions.
Fat breakdown does not produce immediately visible changes.
However, the speed at which changes are felt may vary depending on how the intervals between treatments are scheduled.
Onda lifting is designed around these intervals and the two processes of fat breakdown and collagen regeneration.
If the intervals are shortened or extended arbitrarily, the results may instead take longer to appear.

Microwave-Frequency Onda Lifting
The Real Reason It Cannot Be Completed in One Session
It is easy to view a double chin simply as a problem caused by excess fat. In reality, it is a complex change that occurs as both cell size and the elasticity of the skin beneath the chin decline. If only the cells are reduced, sagging skin may remain and make the area appear even looser. If only collagen is stimulated, the fat remains, making the improvement in the contour feel limited.
This is why repeated treatments are needed. When heat is delivered to the fat layer with the 7 mm handpiece, fat-cell breakdown is induced, but it takes time for the broken-down fat to be eliminated. The collagen stimulated with the 3 mm handpiece also takes several weeks for new fibers to form. Structurally, it is difficult to complete both processes simultaneously in a single treatment. Ultimately, dividing the treatments into multiple sessions with time between them is closer to the body’s natural process.

The Order in Which Fat and Collagen Regenerate
The 7 mm deep handpiece works by applying heat to the fat layer with microwave energy, inducing cell breakdown. During this process, deep collagen fibers are also stimulated, activating fibroblasts. Because the epidermis is protected by contact cooling, the heat is concentrated only in the dermal layer. The 3 mm shallow handpiece contracts surface collagen fibers, creating a tightening effect.
As these two depths work together, they target both the fat and skin elasticity in the double-chin area. The broken-down cells are eliminated from the body over time, while collagen remodeling takes place over a longer period. Because of this difference in timing, repeated treatments at set intervals are needed for the two effects to accumulate and refine the contour.
The fact that it is a non-invasive method with relatively little discomfort is also advantageous for continuing repeated treatments. Being able to continue each session without a significant burden is one factor that makes repetition possible.

Changes in the Jawline That Become More Noticeable with Repetition
Immediately after treatment, you can wash your face on the same day without significant swelling or pain. However, it is best to cleanse gently so as not to irritate the area. This comfort makes it possible to continue receiving multiple treatments at regular intervals without much burden. For about a week after treatment, avoiding saunas, strenuous exercise, and alcohol may help with recovery.
After the first treatment, fat elimination and collagen production gradually proceed, and the jawline begins to look more defined over time. This change tends to accumulate with each additional session. Applying sunscreen thoroughly can help maintain stable skin condition during the recovery process. Results may vary depending on the amount of fat and the condition of each person’s skin. It is also natural for the degree of change to feel slightly different from one session to the next.

Ultimately, Keeping the Intervals Is What Matters
Because a double chin involves two overlapping issues—fat and elasticity—it is difficult to complete the process in a single treatment. Onda lifting is designed with repeated treatments in mind so that these two processes can progress naturally together. The treatment interval and number of sessions may vary depending on the amount of fat and the condition of the skin. Ultimately, rather than rushing, it may be more important to maintain the intervals in accordance with the body’s regenerative process.
