Hello. We are Chang Dermatology, your beauty partner dedicated to keeping your skin young and healthy.

Thermage FLX is a procedure that delivers radiofrequency energy deep into the skin to induce thermal stimulation.

In this process, collagen in the skin contracts, and as the regeneration process continues, changes in skin elasticity and density may gradually appear.

As a non-invasive procedure performed without incisions or injections, it is characterized by inducing changes in the internal structure while minimizing damage to the skin surface.

How much pain is felt during Thermage FLX?

For many people, the biggest question before the procedure is the pain associated with Thermage FLX.

As radiofrequency energy is delivered into the skin, you may feel a momentary sensation of heat or tingling, but the degree of discomfort varies depending on individual skin thickness and pain sensitivity.

In general, it is often described as more of a “warm pressure” than unbearable pain, and the procedure is carried out in a way that reduces burden by adjusting the intensity during treatment.

What methods are used to reduce pain?

Adjusting the energy level according to the skin condition before the procedure is an important factor in easing discomfort.

In addition, a cooling system works together to reduce thermal stimulation on the skin surface, helping to lessen Thermage FLX pain.

If necessary, numbing cream may also be used, and if discomfort is felt during the procedure, the intensity can be adjusted immediately, allowing for a relatively stable treatment process.

When can the effects of Thermage FLX be felt?

The effects of Thermage FLX do not appear immediately after the procedure but tend to emerge gradually over time.

After the procedure, you may feel as though your skin is tightened, and as the collagen regeneration process progresses, changes in skin elasticity and texture may be gradually felt between one and three months later.

These changes vary depending on the individual's skin condition, and there are also individual differences in how much Thermage FLX pain and effectiveness are perceived.

How long does it last?

In general, the maintenance period for Thermage FLX is often described as about 6 months to 1 year.

However, this is not an absolute standard and may vary depending on the speed of skin aging, lifestyle habits, and post-treatment care.

Rather than viewing it as a one-time procedure, it is helpful to understand it as a form of periodic care tailored to your skin condition.

Adjusting the treatment interval while considering Thermage FLX pain is also an important point.

Who is Thermage FLX suitable for?

If you feel that your skin is no longer as elastic as before, or if sagging or fine lines are becoming a concern, Thermage FLX may be worth considering.

It can be a relatively suitable option for those who find surgical methods 부담스럽 and want care with a short recovery period.

However, because the perceived pain and effectiveness of Thermage FLX can differ depending on skin condition, it is necessary to confirm this through sufficient consultation before the procedure.

What care is helpful after the procedure? After the procedure, care that minimizes skin irritation is important.

It is best to avoid excessive heat stimulation, alcohol, and smoking, and consistent sunscreen use and moisturizing care may be helpful.

Even these basic care steps can have a positive effect on skin recovery and maintenance after the procedure, and can also help relieve temporary sensitivity that may occur afterward.
