If Thermage penetrates the skin 4mm, how is it that it does not cause fat loss?

Thanks for your good question. Thermage is specifically designed to treat the dermal structure and does not typically work deeply enough to penetrate the subcutaneous fat just under the dermis. The temperature is also set to constrict tissue and stimulate collagen production, not destroy fat cells. Make sure you work with a board-certified dermatologist to ensure your Thermage treatment is both safe and as effective as possible.

You ask a very good question and one I hear frequently in my practice. Thermage uses radiofrequency energy to heat the underlying dermal structure to constrict tissue and stimulate collagen production. The depth of the procedure can be adjusted to meet the unique needs of each patient. The device is not designed to reach the subcutaneous fat that lies just underneath the dermal structure. That said, it is essential that you work with a board-certified dermatologist with extensive experience using the Thermage device to ensure your procedure is safe and meets your expectations in terms of results.
