How long Botox and fillers actually last: a realistic maintenance timeline

The short answer: neuromodulators like Botox last three to four months for most people, hyaluronic acid fillers last six months to two years depending on the product and where it is placed, and skin treatments like lasers need periodic upkeep to hold their gains. Nothing in the non-surgical toolkit is permanent, and that is by design. What matters is knowing the real timeline before you start, so maintenance is a plan rather than a surprise.

Neuromodulators: three to four months, reliably

Botox and its cousins wear off on the most predictable schedule in aesthetics. The muscle-relaxing effect peaks around two weeks, holds for roughly two to three months, then fades gradually as nerve endings recover, with movement usually fully back by month four. The American Academy of Dermatology puts the typical duration at three to four months, and a minority of patients stretch to six (see the AAD's overview of botulinum toxin therapy). In practice, most people settle into three to four appointments a year. Frequent, very early re-treatment is not the goal; letting each round fade most of the way keeps dosing conservative and expression natural, a theme we cover in neuromodulators: how they soften wrinkles.

Fillers: six months to two years, depending on where and what

Filler longevity varies far more, because it depends on the product's thickness and how much the treated area moves. Lip filler, living in the most mobile part of the face, tends to soften in six to twelve months. Cheek and jawline fillers, built from firmer products in areas that move less, commonly hold twelve to twenty-four months. Under-eye filler often outlasts expectations, sometimes persisting for years. Two useful caveats: fillers fade gradually rather than vanishing on a date, and imaging studies have found traces of product long after the visible effect is gone. That is one more reason restraint matters, because new filler layered on old filler is how faces drift toward the overfilled look, as we explain in dermal fillers: restoring volume and contour.

Skin treatments: results that build, then need upkeep

Lasers, light treatments, and skin boosters work differently. A series of sessions builds the result over several months as collagen remodels, and the improvement then ages with you. Most practices suggest a maintenance session every six to twelve months to hold the gains. The same applies to radiofrequency and ultrasound tightening, where collagen built after a treatment persists but does not stop the clock.

What a realistic year looks like

Put together, a typical maintenance year for someone running a combined plan looks like this: neuromodulator top-ups three to four times, filler refreshed once (or less, on alternate years for firmer products), and one or two skin-quality sessions. That rhythm is why we suggest budgeting annually rather than per visit, a point covered in detail in what a non-surgical facelift costs.

The takeaway is that duration is a feature to plan around, not a flaw. Treatments that wear off can be adjusted as your face changes, dialed back, or simply stopped. Knowing the honest timeline up front turns maintenance from a treadmill you fell onto into a schedule you chose.
