If you are struggling with acne scars and enlarged pores and started looking into Secret RF, you might have questions popping up all at once, such as "Does it really work for scars?", "Is one session enough?", or "How long is the recovery?" Many people also find it confusing how it differs from standard lasers.

To give you a quick answer, Secret RF is a treatment that delivers radiofrequency (RF) heat into the deeper layers of the skin using fine needles to stimulate collagen regeneration from within. Rather than peeling or resurfacing the outer layer, it works by filling up the skin texture from the inside out. Therefore, instead of a single session, it is common to space out multiple treatments to build up visible improvements. Once you understand how it works, you will naturally see why multiple sessions are needed and what precautions to take during recovery.

How does Secret RF work on scars and pores?

Secret RF works by passing insulated microneedles through the skin into the dermal layer and emitting radiofrequency (RF)* heat from the needle tips. Because the structure protects the epidermis while delivering thermal stimulation only to the deeper layers, that heat triggers the process of generating new collagen. Understanding that microneedle RF stimulates fibroblasts by applying thermal energy to the dermis, inducing collagen and elastin regeneration to improve acne scars and enlarged pores clarifies why this treatment targets both scars and pores simultaneously.

Radiofrequency (RF)*: Energy that generates heat within tissues using high-frequency electrical currents. It is used to warm the deep layers of the skin to stimulate collagen regeneration.

Acne scars are depressed areas where collagen in the dermis has been damaged, so as new collagen fills in from within, the edges become smoother. Enlarged pores also appear less noticeable as the elasticity of the surrounding dermis is restored. Another key feature is that the recovery process is relatively short since the skin surface is not peeled or resurfaced.

How does it differ from skin-resurfacing lasers?

When people think of treatments for scars and pores, lasers often come to mind first, but the mechanism is quite different. Ablative lasers, which finely peel the skin surface, provide clear results but tend to leave scabs and redness for a longer recovery period. Secret RF, on the other hand, protects the epidermis while delivering heat only to the deeper layers—aiming for collagen regeneration while reducing the recovery burden.

Rather than one being strictly superior to the other, the right approach depends on your scar depth and skin condition. In some cases, both methods are used together or in stages, so it is best to determine the right combination for your skin during your consultation.

How many sessions are typically required, and at what intervals?

Secret RF is a treatment that requires multiple sessions rather than a single visit. Because collagen regeneration cannot be fully completed with just one stimulation, sessions are performed at set intervals to accumulate changes step-by-step. Deeper scars may require more sessions. The intervals are usually decided based on the skin’s recovery time, and the gradual progress over time looks like this:

There is no fixed formula, as the number of sessions and intervals vary depending on the severity of the scars, skin recovery speed, and your personal goals. Because we monitor how your skin heals after each session before scheduling the next, the overall treatment timeline usually spans over a few months.

Why Beauty stone Hapjeong?

At Beauty stone Hapjeong, before recommending Secret RF, we carefully assess your scar depth and pore condition first. Instead of using overly aggressive settings all at once, we customize the intensity based on your lifestyle, recovery burden, and goals. Because recovery rates vary for everyone, it is incredibly important to check the skin's condition at every visit and adjust the timing of the next session. As a cozy clinic conveniently located just a short walk from Hapjeong Station, we can closely monitor each individual's recovery progress and tailor your treatment schedule together.

Post-Treatment Recovery: Normal Reactions vs. Warning Signs

Mild reactions are common for a few days after a Secret RF session. Most of these resolve naturally without any special treatment.

• Tiny red dots (needle marks) or a slight tingling sensation — Usually fades within one to two days

• Mild swelling or heat sensation — Typically subsides within a few days

• Rough skin texture — Gradually improves as the skin surface heals

During the recovery phase, be diligent with sunscreen and avoid harsh exfoliants or active skincare ingredients for a few days. However, please contact the clinic if you experience any of the following warning signs:

• Swelling and pain that worsen after several days

• Oozing, or spreading redness accompanied by intense heat — Potential signs of infection

• Hyperpigmentation that persists for a long time — Requires adjusting your post-treatment care plan

Please note that this article provides general information. To safely determine if this treatment is right for you and to plan your session details, a doctor's examination is highly recommended.

Frequently Asked Questions

Q. Is a single Secret RF session enough to treat acne scars?

A. While you may notice subtle improvements after a single session, scars generally require multiple treatments to accumulate collagen regeneration and soften the scar edges. Deeper scars may need more sessions. The optimal number of treatments for your skin should be determined during a medical consultation.

Q. Can I get the treatment if I have active acne breakouts?

A. If you have active, inflammatory acne, it is safer to adjust the timing of your treatment. Depending on your skin's condition, we may recommend soothing the breakouts first or adjusting the intensity of the Secret RF. It is best to decide on the timing after a medical professional evaluates your current skin status.

Q. How soon can I apply makeup after Secret RF?

A. While it is often possible from the day after the treatment, it is safer to postpone color cosmetics for a day or two if tiny needle marks are still visible. During the recovery period, keep your routine simple, focusing on gentle moisturization and sun protection. Please consult with your provider for specific timing based on your skin's healing.

Q. Does Secret RF help with enlarged pores?

A. Loss of elasticity in the surrounding dermis contributes to the appearance of enlarged pores. When collagen regeneration is triggered, the pores can appear less prominent. However, unlike scars, pores do not get filled in instantly; instead, the skin texture gradually refines over multiple sessions. Since results vary from person to person, we recommend discussing expected outcomes during your consultation.
