Can Dermal Fillers be affected by Lasers?

Aesthetic treatments with neuromodulators like Botox, dermal fillers,  PDO threads, and lasers are often all combined during a single treatment session at Style Aesthetics.  How do they affect one another? Many believe that heat or device type treatments like lasers promote the loss of filler or a reduction in their efficacy.  Common device type of treatments that use a form of heat include lasers, radiofrequency, IPL, and microneedling with radiofrequency.

Hyaluronic acid fillers are typically heated and sterilized during manufacturing and prior to receiving them in clinic.  Fillers made of calcium hydroxylapatite like Radiesse, PMMA fillers like Bellafill, or PLLA fillers like Sculptra are subject to high temperatures and will not melt when exposed to treatments and devices that require heat. A common question that many wonder is how long after filler can a patient receive a device-type treatment?  The answer to this depends on several factors and a discussion with your provider will determine the best time for such treatment.

An example of why you may want to delay injectables until afterwards is during radiofrequency treatment with microneedling.  Microneedling with radiofrequency penetrates deep into the tissues and creates microchannels. Theoretically, when injecting filler immediately after,  the product has to move through the created channels before it integrates within the tissue. The heat from this type of treatment will not affect dermal filler.

High frequency ultrasound, radiofrequency, or CO2 lasers also will not melt filler.  The caveat to these types of treatments is that some of these devices include a suction and massage function.  With vibration and massage, the effects of fillers may not be very apparent as the devices may disperse the product.

The key steps as Dr. Rajani discusses during treatments include: treatment with heat first, having the patient rest for 15 minutes afterwards, followed by injectables with fillers or Botox.  It is very possible to perform combination treatments successfully following this order. Simply, heat will not melt or dissolve dermal fillers or reduce their efficacy.
