Understanding Treatment Longevity: How Long Do Results Last?

Last updated: 5 March 2026

Understanding how long aesthetic results last is one of the most important factors in treatment planning. Longevity varies enormously depending on the procedure, products used, individual metabolism, lifestyle factors, and aftercare compliance. This guide, informed by clinical trial data and the British College of Aesthetic Medicine (BCAM), provides evidence-based timelines.

Factors that influence longevity

Research in the Journal of Cosmetic Dermatology (2024) identifies key factors:

• Metabolic ratehigher metabolisms break down products faster
• Treatment areahigh-mobility areas metabolise fillers more quickly
• Product typehigher cross-linked HA fillers last longer
• Injection depthsupraperiosteal placement lasts longer
• Sun exposureUV accelerates collagen degradation between treatments
• Smoking and alcoholimpair tissue quality
• Skincare regimenretinoids, SPF, and antioxidants support results

Injectable treatment timelines

Botulinum Toxin

Duration: 3-4 months (first); 4-6 months with regular maintenance. A Dermatologic Surgery (2023) study showed patients receiving consistent treatment for over two years experienced extended duration, likely from muscle atrophy.

Hyaluronic acid fillers

Duration: 6-18 months by area:

• Lips6-9 months (orbicularis oris movement)
• Nasolabial folds9-12 months
• Cheeks/midface12-18 months (deep, static tissue)
• Jawline/chin12-18 months (supraperiosteal)
• Tear troughs12-24 months (minimal movement)
• Temples12-18 months

Biostimulators

Duration: 18-36 monthsthey stimulate your own collagen:

• Sculptraup to 25 months (VEGA study, Aesthetic Surgery Journal)
• Radiesse12-18 months
• Polynucleotides6-12 months, maintained with 2-3 sessions/year

Skin treatment timelines

Chemical Peels

1-6 months per session. Cumulative benefits with maintenance every 4-6 weeks.

Microneedling

3-6 months per session. Collagen remodelling continues 6 months post-treatment. A 3-4 session course lasts 6-12 months.

Laser Treatments

Variable, potentially years. A 10-year follow-up in Dermatologic Surgery (2022) showed maintained improvements from fractional CO2 laser with adequate sun protection.

Maximising treatment longevity

1. Daily SPF 50non-negotiable
2. Consistent retinoid use
3. Antioxidant protectiontopical vitamin C
4. Maintenance schedulestop-up before results fully fade
5. Hydration and nutritionomega-3s, vitamins A, C, E
6. Smoking cessation

Frequently asked questions

Do results last longer with frequent treatments?

For botulinum toxin, yes, muscle atrophy extends duration. For fillers, top-ups maintain consistency and may require less product.

Can I switch filler brands?

Yes, but your practitioner must know what products are in situ for different reversal protocols.

Will I look worse when treatments wear off?

No. You return to your pre-treatment appearance. The perception of “looking worse” is psychological (“baseline reset”), you have become accustomed to your treated appearance.
