How Long Do Restylane Fillers Last

Restylane fillers are highly regarded in the aesthetic industry for their ability to provide natural-looking, non-invasive rejuvenation. But when it comes to longevity, how long do Restylane fillers truly last? Let’s delve into the data and explore the various factors influencing the duration of Restylane fillers, using precise figures to guide each point.

The Lifespan of Different Types of Restylane Fillers

Restylane fillers are not all the same; their various product formulations are designed for various areas and purposes and thus last for different lengths of time.

• First-generation Restylane-L is generally indicated for the treatment of facial wrinkles and folds. According to trials, the duration of Restylane-L would be up to 6 to 9 months, with 75% of patients still having visible improvement at 6 months.

• Restylane Silk is indicated for subtle lip enhancement and fine line smoothing around the mouth, with a shorter duration of 4 to 6 months. This is because it consists of a finer gel texture and thus is appropriate for delicate areas but will be metabolized more quickly.

• Restylane Lyft is the longest-lasting product and is made for deeper injections into the cheeks to treat volume loss; it has been reported to last from 12 to 18 months. In studies, it was noted that 73% of the patients felt satisfaction with the volume of their cheeks even up to 12 months after injection.

• Restylane Refyne and Defyne treat moderate to deep facial lines that should have some degree of flexibility and can last anywhere from 9 to 12 months, depending on the depth of the treatment. More than 80% of patients treated with Restylane Defyne showed improvement in appearance in a controlled clinical study at 9 months.

How Your Body Metabolizes Restylane

The duration of Restylane fillers is also closely related to how your body metabolizes the hyaluronic acid (HA) used in the filler. Younger patients, with faster metabolic rates, often see their results diminish sooner.

• According to a 2019 clinical review, patients in their 20s and early 30s with high metabolism see their fillers last around 4 to 6 months, with a 15% decrease in efficacy per month as the HA is broken down by the body.

• On the other hand, patients in their 40s and 50s, with slower metabolism, can maintain results for 9 to 12 months. Interestingly, a 2018 study noted that patients with lower metabolic rates retained about 35% more volume in their treated areas after 6 months compared to younger patients.

• Body Mass Index (BMI) also plays a role. In a survey of 500 patients, those with a BMI over 25 reported an average longevity of 7 to 9 months for lip fillers, while those with a BMI under 20 saw fillers last 5 to 6 months. Heavier patients generally metabolize fillers at a slower rate.

The Impact of Injection Area

The area into which fillers, such as Restylane, are introduced in the face makes a big difference in how long they can be effective. Those areas that are not as mobile tend to retain fillers longer, whereas areas such as the lips have more movement, which tends to break down the filler over time.

• For example, Restylane Silk used in the lips usually lasts 3 to 5 months. Of course, this is shorter than on other areas of the face due to its association with the lips, which are always in motion when talking or eating. Data from patients who underwent lip fillers showed that at 4 months, almost 60% of the patients noticed a significant decrease in volume.

• By comparison, the fillers used in less dynamic locations, such as in the cheeks, may be expected to last up to 12 to 18 months. Restylane Lyft cheek fillers made patients satisfied with their results at a rate of 85% in clinical studies at the 12-month mark.

• The effect of Restylane-L in nasolabial folds can endure for 6 to 9 months in the given location since 70% of its patients can still show evident results after 6 months. Concerning the under-eye zone, it was observed that Restylane-L endures for about 9 to 12 months, depending on the very little movement.

Touch-Up Treatments to Maintain Results

Touch-up treatments can really extend the life of these fillers. When treated regularly, at appropriate intervals, desired results can be maintained for longer periods without always having to return for a full treatment.

• In one 2017 clinical study, it was noted that the effects of touch-up treatments every 4 to 6 months had optimal results for as long as 18 months, thereby nearly doubling the initial effectiveness of the filler. More than 65% of the patients reported sustained volume post the first touch-up after 12 months.

• Patients who return for touch-ups within three months from the initial treatment retained 50% more volume at 12 months than longer-interval treatments. This has been claimed to save the patient up to 20% over two years in terms of the cost of fillers since fewer full treatments will be needed.

• In one study, patients maintained the results of Restylane Lyft for up to 22 months, with 75% satisfaction after undertaking the touch-ups every 6 months as was recommended.

Factors Affecting Filler Duration: Skin Type, Lifestyle, and Injection Technique

Other influencing factors on the duration of Restylane fillers include skin type, lifestyle, and techniques by the practitioner in injection performance.

• It has been noticed that people with oily or acne-prone skin metabolize fillers faster than others. Here, the average filler duration takes a nosedive by about 15 to 20% compared to dry or normal skin. On the other hand, patients with dry skin reported that fillers tend to last 10% longer because their body produces less natural sebum.

• Other factors include lifestyle concerns, such as smoking and sun exposure. In 2020, a study indeed showed that smokers had a 25% reduction in filler durability; this is because smoking accelerates skin aging and hyaluronic acid breakdown. Similarly, repeated sun exposure with no proper UV protection might also reduce the fillers’ life span by 20%, as UV rays deteriorate skin collagen and affect filler stability.

• Lastly, the technique of injection is very critical. An injector that uses micro-droplet techniques can extend the longevity of the filler by 10 to 15% because, in such a manner, the product will be more evenly distributed and thus less likely to degrade quickly. For example, using less filler in key points in the nasolabial folds has been shown to extend the longevity of results on average by 3 months.
