One session lasts one to one and a half years. Firmness rises over three to six months as collagen accumulates, because new collagen takes that long to form while the heated areas heal. Comparing a few months later, rather than right after, is how you actually see the change.

Both are monopolar RF and heat inside the skin on the same principle. Thermage is the original device; Oligio was developed in Korea and holds both Korean approval and US certification. The practical difference is availability — more clinics offer it, and the cost tends to be lower.

It feels hot and prickly during the session — that comes from raising the temperature enough for collagen to contract, and the power is adjusted to stay within what you can tolerate. There is no downtime and you can wear make-up the same day; just skip the sauna for a week and keep up sun protection.
