Radio Frequency for acne scars treatment

Acne could be a common affliction among many teens and a few adults that usually resolves over time. However, the severe sequelae of acne scarring can cause long-term psychological and psychiatric problems.

There exists a mess of modalities to treat acne scars like more invasive surgical techniques, subcision, chemical peels, ablative lasers, fractional lasers, etc.

A more modern technique for the treatment of acne scars is nonablative radiofrequency (RF) that works by passing a current through the dermis at a preset depth to supply small thermal wounds within the dermis which, in turn, stimulates dermal remodeling to supply new collagen and soften scar defects.

This review demonstrates that out of all RF modalities, microneedle bipolar RF and fractional bipolar RF treatments offer the most effective results for acne scarring. An improvement of 25%–75% are often expected after three to four treatment sessions using one to two passes per session.

Treatment results are optimal approximately 3 months after the ultimate treatment. Transient pain, erythema, and scabbing can be the common side effects. Further studies are needed to work out what RF treatment modalities work best for specific scar subtypes in order that further optimization of RF treatments for acne scars is often determined.

There is a large number of treatment options that are traditionally used for the treatment of acne scars. These include many ablative measures like chemical peels, subcision, ablative laser, dermabrasion, dermal grafting, punch excision, punch elevation, punch grafting, and surgery.

Besides, minimally invasive micro-needling with a derma roller are often used to treat acne scars. Alternatively, the reduction of acne scars are often accomplished by using temporary fillers.

The matter with many of those procedures is that they’re invasive and may cause an increased risk of depigmentation, scarring, and infections with prolonged healing.

Newer treatment modalities to decrease the propensity for postinflammatory hyperpigmentation and aforementioned problems have emerged like nonablative fractional lasers and radiofrequency (RF) treatments. This induces a rapid healing process within the dermis and upregulation of the latest collagen production.

Radio Frequency delivers all the benefits with little discomfort and inconvenience:

  • Improves skin tone and texture
  • Reduces wrinkles and fine lines
  • Rejuvenates and tightens skin
  • Reduces acne scars, skin pigmentation, open pores, and stretch marks

RF works well with all skin types with measurable results, and is  also recommended to treat the following:

  • Scars due to acne vulgaris especially rolling and box scars
  • Minor raised scars due to acne, vaccination, burns, and chickenpox
  • Large open pores from oily or combination skin
  • Saggy skin, wrinkles, and fine lines
  • Stretch marks
  • Dull complexion

RF treatments are an alternative to standard methods of acne-scar treatment and may be used as monotherapy or as adjuvant therapy with fractional lasers. Unipolar, bipolar, and fractional are the three major sorts of RF treatments, the foremost basic is the unipolar/monopolar RF device that uses one electrode and a grounding pad on the skin. This RF modality goes to profound penetration of the dermis but it may increase more pain and discomfort to the patient. Bipolar RF offers an alternative to unipolar/monopolar RF which will deliver a more focused current to the dermis with less pain because of the requirement to use lower amounts of energy to attain a similar thermal effect.

Fractional RF uses an array of electrodes that allows for various zones of thermal wounds to be made between areas of various unaffected zones, thus stimulating dermal remodeling and allowing a supply of reservoir cells to push healing. Variations of fractional RF exist that employ microneedles to deliver electrical current to a specific depth within the dermis that decreases damage to the epidermis. Furthermore, The pretreatment with a nonablative laser lowers the tissue impedance (resistance to the flow of current) within the skin to permit deeper penetration of the RFs, decreased level of pain, and reduced amount of RF energy to succeed in the optimal thermal dose, thus decreasing collateral effects to the encircling dermis round the area of scarring and decreasing the propensity for damage, which can include blistering burns or inflammatory nodules.
