![Spicules, RF & Skin Tightening: What I’d Use, What I’d Avoid
One of the biggest conversations in skin right now: spicule skincare and skin tightening.
Well meet LIVE with a Korean Expert in spicules and skin care From Korea as well.
Ask her questions.
We’ll talk about the new Korean spicule technology, why it feels different from traditional skincare, who it may be good for, who should be cautious, and how to use it without overdoing your skin.
Then we’ll move into skin tightening — both at home and in clinic.
I’ll cover XTherma and at-home options like NEWA RF, where it fits, what realistic expectations should be, and how it compares to newer in-office technologies.
XTHERMA is the Korean skin-tightening device I recently traveled to Korea to see for myself. I’ll explain why energy, heat, cooling, fat protection, and treatment depth all matter when the goal is tighter skin — not a thinner or hollow-looking face. You know Xerf, Thermage and Ulthera (Ultrasound) but you have not even heard of Xtherma
What we’ll cover:
* What spicules are and why they are trending
* How spicule skincare may help with texture, glow, pores, and fine lines
* Who should avoid or be careful with spicules
* How to combine spicules with retinol, acids, LED, exosomes, and skin boosters
* What at-home skin tightening can and cannot do
* Where NEWA fits in the skin-tightening world
* Why newer Korean RF technology is getting attention
* XTHERMA, skin tightening, cooling, and fat protection
* How to think about tightening skin without aging the face
