Laser treatments are popular in treating many skin conditions. Yet, the traditional ablative laser technology has many problems. These lasers can easily damage the uppermost layer of skin called the epidermis. It’s also very difficult to control the depth to which these lasers penetrate the skin. But the modern fractional technology overcomes these disadvantages of the ablative lasers. The latest fractional radiofrequency microneedle devices are much less invasive, less damaging1 and offer greater selectivity in treatment.
Microneedles2 are very small, microscopic needles that can penetrate only to a certain depth in the skin. The latest fractional radiofrequency devices use insulated microneedles and radiofrequency to deliver energy to heat up a very specific area within the dermis of the skin. The use of radiofrequency and microneedles allow the delivery of energy at a very specific point, so it dramatically reduces the risk of harming the epidermis at all. This technology has been very successfully used in the treatment of wrinkles, atrophic scars, and hypertrophic scars.

A recent study regarding the effects and actions of non-ablative radiofrequency treatment was done by scientists from the Department of Dermatology and Cutaneous Surgery at the University of Miami Miller School of Medicine. Their findings were reported in the peer-reviewed Clinical, Cosmetic and Investigational Dermatology Journal3.
The study revealed that 3-4 sessions of fractional radiofrequency microneedling using 1-2 passes each time resulted in up to 75% improvement in acne scars. Some minor side effects such as scabbing or transient pain were noted. These side effects completely subsided within 2-3 months at which time, the best results were seen4.
Fractional radiofrequency microneedling has potential in the treatment of acne, but the past studies done to evaluate the usefulness of the technique are limited. None of the studies report the measurement of objective parameters such as the number of inflammatory and non-inflammatory acne lesions or the levels of sebum excretion. Until now.
The safety and efficacy of fractional radiofrequency microneedling in the treatment of acne5 were investigated in a recent clinical trial, though. The trial consisted of 25 subjects suffering from moderate to severe acne.
These subjects were treated with fractional radiofrequency microneedles three times at one month intervals. The objective parameters considered were acne lesion count, subject satisfaction score, sebum excretion level and adverse effects. These parameters were recorded before the treatment (baseline measurements) and at 2, 4, and 12 weeks after the first treatment and 4, 8 and 12 weeks after the last treatment.
The results revealed that the number of acne lesions, both inflammatory and non-inflammatory, decreased significantly6. The sebum excretion and subject satisfaction scores were statistically favorable at each point of measurement compared to the baseline (p<0.05). It was also observed that the inflammatory acne lesions had better improvement than the non-inflammatory lesions. Some minor and transient adverse effects, such as pinpoint bleeding, pain, and erythema, were also observed but did not warrant the stopping of treatment.
This study shows the merits of fractional radiofrequency microneedling in the treatment of acne vulgaris.
This technique has been used quite successfully in the treatment of scars resulting from acne7. However, there are many examples where this very technique was used to get rid of the acne itself.
Radiofrequency Microneedling8 helped this woman who was suffering from severe acne. She had tried everything and nothing seemed to be working. She tried many home remedies including vinegar and honey face wash. It’s not such a bad idea either, since the acidity of the vinegar and the antibacterial properties of honey can help treat acne, but they didn’t work in her case.
She also tried many other things such as changing her diet. She was advised to use birth control pills, but because of the fear of side effects she chose to skip that. Ultimately she decided to go for microdermabrasion treatments9. This treatment completely changed her life. She went for the treatment and for the first time in her adult life, her skin started to clear up.
So if nothing else seems to be working to treat your acne, this might be something to consider. But before diving in and spending that much money on this new treatment, we suggest taking a closer look at Exposed Skin Care reviews.
Over 90 percent of users say they get results with it. We aren’t surprised at that though, since their kits have everything needed to get rid of acne in most cases. That is, it provides a number of products containing many natural ingredients known to kill the bacteria that can cause acne, cleanse any dirt and grime buildup from the face and keep it moisturized. Just as the American Academy of Dermatology recently confirmed, it takes more than one step and more than one product to get rid of acne for good.
