Skin Tightening and Smoothing With Radiofrequency Skin Rejuvenation
RF stands for radio frequency, an energy that heats skin to stimulate collagen and elastin production.radiofrequency skin rejuvenation device The result is skin tightening and smoothing, which can help reduce fine lines and wrinkles and improve skin texture. This noninvasive treatment is most suitable for those with mild to moderate skin laxity who don't want to take the plunge into surgical cosmetic procedures.
The best RF devices for skin tightening are those that penetrate deeper into the epidermis, dermis and subcutis (the fatty layer under the dermis) to 'bulk-heat' underlying tissues, which is where wrinkles and loose skin begin to form.radiofrequency skin rejuvenation device A good RF device should also be safe for all skin colours, unlike lasers which can cause discolouration in darker complexions.
Some RF devices have different penetration depths depending on whether they have bipolar or monopolar electrodes.radiofrequency skin rejuvenation device This has a direct impact on how much energy is delivered to the skin. A monopolar RF device forces focused heat into the three skin layers through a stick-on 'conductivity pad' placed on the body, which is why this type of RF device is often favoured for skin tightening treatments. However, a monopolar RF machine doesn't always deliver the same results as a bipolar device because it can be difficult to maintain an optimal level of temperature throughout the treatment.
Alternatively, some RF devices work by heating the deep layer of the skin to an optimal collagen-producing temperature. When this happens, the body releases heat-shock proteins to heal the wound and churn out new, tighter skin cells. This is the kind of RF technology used in thermalift and other skin tightening treatments, and it works well on both the face and body.
For skin-tightening on the body, look for a monopolar RF device that uses a skin-friendly gel like CurrentBody's Skin Sense technology. This ensures that the RF energy is suited to your skin's resistance, so it doesn't burn or damage it. Thermage FLX is a good example of this, as is the Venus Legacy, which comes with a body headpiece.
Other options include a combination of RF and microneedling to tackle both scars and saggy, stretch marks on the body. The Morpheus 8 is the most well-known of these, with Intracel and Focus Dual offering a similar combo.
RF energy can also be used to treat pigmentation and sun damage. A course of six 'fractional RF resurfacing' sessions, spaced a month apart, will usually achieve significant improvement, with the results lasting 18-24 months. However, be prepared to repeat your treatment as old sun damage lies underneath the surface preparing to rise to the top again. This is why you need to be religious about applying SPF 50 every day, regardless of which resurfacing technique you choose.
