Very little is visible on the day. Some patients report a mild tightness on the way home; the substantive change arrives slowly, as collagen is laid down through the treated depth and the slackened line draws upward. The clinic describes the concerns this work addresses as skin density, texture, pores, elasticity, a dropped line, general signs of ageing, lost volume and fine lines, and those do not all move at the same speed.
For hold, G Clinic gives six months to a year or more. Where a particular face lands inside that span turns on age, starting laxity, skin quality and what you do afterwards, so treat the range as a range and plan repeat sessions around your own review, never around a calendar rule. Where a line has already dropped beyond what a collagen response will carry, mechanical support is the discussion instead, which is what Thread Lift covers.
The two courses shown on this page are records of individual patients at this clinic, published with consent, and they promise nothing for a third face. A director will tell you at consultation when the realistic answer for your anatomy is a modest change, and that conversation happens before you book, never after.
