Some treatments take weeks to look their best.
Anti-wrinkle injections show initial change in 3–5 days and settle at around two weeks. Book them at least three weeks before travel to allow any unexpected adjustment or a top-up.
Dermal fillers often have immediate effect but can bruise and swell. Leave four weeks before major events for settling and contour refinement. PRP and polynucleotide-style skin boosters encourage collagen over several weeks, so plan these at least six to eight weeks ahead if you want visible skin quality improvement by holiday time.
