Ultherapy / Thermage FLX

You have heard of them, right? (Or perhaps you haven't??) They are representative skin-lifting treatments~

When we previously covered Ulthermage,

we briefly compared and analyzed the two treatments.

Today, we would like to take one step further and look at them more closely~

It may be a little late and they may already be past their prime, though. (Hopefully not~)

They have the common feature of being non-invasive lifting treatments.

This refers to treatments that improve sagging by increasing firmness

using heat, ultrasound, lasers, electrical current, and other methods

without making incisions in the skin.

However,

they provide different effects because the energy used and the areas treated differ.

When we break them down in detail, quite a few aspects are different, aren't they?

Looking at the characteristics of each treatment,

first, Ultherapy

It targets the SMAS layer and has a lifting effect that firmly raises sagging skin,

making it particularly effective for improving a weakened jawline and double chin~

However, because it delivers energy to deeper layers,

its effects on fine surface wrinkles and skin texture may be weaker than those of Thermage FLX.

Next,

Thermage FLX stimulates collagen in the dermal layer,

which can help increase overall skin density.

That is why it is particularly effective for improving fine lines around the eyes and mouth.

If sagging skin is your main concern or you want powerful jawline lifting, choose Ultherapy.

If you want to improve fine lines, reduced skin firmness, and the tautness of the skin's surface, choose Thermage FLX.

If you want both effects and have the financial means, consider Ulthermage.

The effects and potential side effects of treatment may vary depending on an individual's skin type and circumstances,

so please be sure to consult a professional before deciding to proceed with treatment.

Today, we looked at Ultherapy / Thermage FLX!
