Fractional RF is one of the advanced and non-invasive methods in the field of skin rejuvenation that has brought about significant transformations. As the name suggests, this method utilizes radiofrequency waves. When these waves interact with the skin tissue, they generate heat, causing fundamental changes in the skin. Fractional RF is also known as MRF, which stands for Microneedle Radiofrequency.
Can Fractional RF Accelerate Skin Rejuvenation?
As we age, tissues and cells undergo aging processes rapidly. Since the human skin is the most visible tissue in the body, signs of aging in this tissue are more apparent and observable every day. Additionally, the skin serves as the body's primary external defense, constantly exposed to various physical and chemical environmental and internal damages, resulting in external changes such as wrinkles, fine lines, spots, and dryness.
The portions of the skin responsible for its firmness are composed of collagen and elastin fibers. These fibers lose their structure over time and due to environmental damage, becoming longer. Consequently, they become loose and weak, contributing to sagging and the formation of wrinkles in the skin. To rejuvenate collagen, old collagen must be broken down, and new collagen must be synthesized.
Collagens have different types, each breaking down at a specific temperature. Therefore, to regenerate collagen, thermal energy must be targeted to a specific depth in the skin where collagen is located to minimize damage to surrounding tissues. RF devices (Radiofrequency) are employed for this purpose. These devices create controlled heat with radiofrequency waves, which are a spectrum of light. However, due to their non-selective heat generation, their effectiveness is limited and can have side effects.
With technological advancements, Fractional RF has been utilized for this purpose. These words are derived from the phrase "fraction by fraction." It works by creating heat in sections of the skin, causing old collagen to break down and regenerate, while surrounding areas cool down and repair the skin.
How is Fractional RF Performed?
It is advisable to visit with clean and makeup-free skin for the day of treatment. The treatment area will be covered with local anesthetic creams. After 20-30 minutes, the treated area is washed and disinfected. The treatment session will last about 10-25 minutes, depending on the treated area. Each person acquires specific equipment before starting the treatment.
The Fractional RF device is designed for single-person use only to prevent disease transmission, and its use for another person (even relatives) is prohibited. After treatment, the skin can be cooled and soothed using an ice pack. The use of a repairing cream at this stage can help reduce inflammation.
Pre and Post-Fractional RF Recommendations:
Pre-treatment recommendations:
- Avoid taking blood-thinning medications such as aspirin and non-steroidal anti-inflammatory drugs (NSAIDs) 5-7 days before treatment.
- Refrain from using any cosmetic products on the skin before Fractional RF treatment.
- Ensure the skin is as clean as possible.
Post-treatment recommendations:
- Use an ice pack to cool and calm the skin after treatment.
- Start using sunscreen immediately after treatment, and its regular use is essential to address potential side effects.
- Avoid sunlight until the healing process is complete.
- Refrain from washing the face for 24 hours after treatment.
- Use zinc ointment and a repairing cream to reduce inflammation.
- Avoid alcohol and blood-thinning medications to minimize inflammation (unless medically necessary).
- Avoid bathing and using anti-wrinkle and anti-aging creams within the first 24 hours.
These guidelines, when followed, contribute to the effectiveness and safety of the Fractional RF procedure.
