When people say “textured marks on brow,” they’re often describing Forehead Acne Scars. Clinically, acne scars form after inflammation from severe blemishes (like cysts and nodules) damages tissue. As the skin heals, it makes new collagen—the protein that gives skin structure—which can lead to visible scars depending on how much collagen is produced.

Principal scar categories

Acne scars fall into two clinical groups: atrophic and hypertrophic. Atrophic scars (depressed/sunken) are most common and form when too little collagen is produced. Hypertrophic scars (raised/firm) form when too much collagen is produced. Secret RF Microneedling is typically chosen for atrophic scars. Hypertrophic scars may need options like steroid injections. Keloids are a type of hypertrophic scar that can grow beyond the original wound and are often a contraindication for collagen-stimulating treatments such as microneedling because they can recur.

Scar subtypes and common patient terms

Within atrophic scars, three subtypes guide treatment choice:

• Rolling Scars: Broad, wavy depressions with soft edges caused by fibrous tethers; often called “pitted” or “sunken.”
• Boxcar Scars: Round or oval depressions with sharp edges, similar to chicken pox scars; common on thicker skin.
• Ice Pick Scars: Small, deep, V-shaped pits; common and harder to treat.

Rolling and boxcar scars tend to respond better to RF Microneedling than ice pick scars, which often need combination approaches.

Scars vs. Post-Inflammatory Hyperpigmentation (PIH)

Post-Inflammatory Hyperpigmentation (PIH) is discoloration (pink, red, or brown marks) after inflammation and is not a true scar. PIH can fade with time and topical care (e.g., salicylic acid, retinol). Many patients have both texture and PIH. A combined plan—such as Secret RF for texture plus chemical peels for pigment—often works best.

Secret RF Microneedling: the science of dermal remodeling

Secret RF Microneedling advances skin rejuvenation by pairing microneedles with radiofrequency (RF) heat to remodel the dermis where scars live.

Collagen Induction Therapy (CIT) basics

Secret RF is a form of Collagen Induction Therapy (CIT). Tiny needles create controlled micro-injuries that trigger healing and new collagen and elastin—key for smoother, firmer skin.

The dual‑action advantage of Secret RF

Secret RF combines the mechanical action of needles with focused RF energy. As needles enter the skin, RF heat targets the deeper dermis to boost collagen and elastin and break fibrous tethers. This inside‑out remodeling addresses both tethering and collagen loss, helping improve deeper acne scars that traditional microneedling struggles to reach.

Device innovations that improve safety and results

Secret RF is a fractional RF system that treats precise zones while leaving surrounding skin intact for faster recovery. Key features:

• Customizable needle depths to match superficial lines or deep acne scars.
• Semi-insulated tips that concentrate RF in the dermis while sparing the epidermis, reducing downtime and the risk of PIH—especially important for darker skin tones.
• Dual handpieces: a 25-pin tip for delicate facial areas and a 64-pin tip for larger areas.

Planning your treatment trip to Korea

South Korea is a global hub for medical aesthetics, known for advanced tech, skilled practitioners, and competitive pricing.

Why use a medical tourism agency

Agencies act as your guide and concierge, arranging consultations, flights, hotels, transport, and translation. With strong clinic networks, they can secure reputable care and better pricing—often saving about $3,000 on a single procedure or 70%–80% on full packages versus U.S. prices—while removing language and logistics stress.

Pre‑procedure checklist

Start with an online or in-person consultation to review your medical history and confirm candidacy. Typical pre-care includes:

• Avoid sun/tanning for at least one week.
• Stop retinoids, AHAs, and other sensitizers at least four days before treatment.
• Disclose any isotretinoin (Accutane) use; treatment is usually deferred if taken within the past 6–12 months due to fragile skin and healing risk.

What to expect in a Korean clinic

Your skin is cleansed, then numbing cream is applied for 30–45 minutes. The Secret RF session takes 15–45 minutes depending on area size. Sensations are usually described as slight heat and pressure. With numbing, most patients tolerate it well, though some find it less comfortable than IPL.

Aftercare and recovery

Expect redness (like a mild sunburn), warmth, and tightness for a few hours to 24–48 hours. Minor pinpoint bleeding or swelling can occur and fades quickly. Keep skincare gentle and hydrating, avoid harsh products, and use high-SPF sunscreen daily. The skin remodels over weeks to months, with full results about three months after the final session.

Clinical outcomes: what to expect

What studies say

A clinical study on Microneedling Fractional Radiofrequency (MFR) in 31 patients with Grade 3–4 acne scars found 80.64% improved by two grades; the rest improved by one grade. Rolling and boxcar scars responded better than ice pick scars. These results support Secret RF as an effective option for moderate to severe atrophic scars.

What patients say

Real-world reviews vary. Many call the procedure “virtually painless” with “amazing” results, fast healing, and visible change after the first session (e.g., $1,200 for three sessions). Others report “no visible improvement,” swelling, itching, PIH, or a rough recovery—often linked to aggressive device settings or reactions to aftercare products. Outcomes depend heavily on practitioner skill, appropriate settings, and proper aftercare.

Setting realistic expectations

No treatment can “get rid of them completely,” but Secret RF can significantly soften atrophic scars through gradual remodeling. Most patients notice changes after the second session, with best results about three months after the final treatment. Expect to commit to multiple sessions and diligent sun protection and skincare.

Risks, side effects, and contraindications

Common, expected effects

Temporary redness and swelling (sunburn-like) for hours to a couple of days are normal. You may see pinpoint bleeding, mild bruising, tightness, dryness, and light peeling as cell turnover increases.

Rare but serious risks

• Hyperpigmentation or hypopigmentation (higher risk with sun exposure and darker skin tones; usually temporary but can persist).
• Scarring and track marks (grid-like patterns), especially with overly deep settings or technique overlap.
• Infection if aftercare hygiene lapses.
• Enlarged pores appearance in rare cases due to collagen contraction dynamics.

Who is not a candidate?

• Pregnancy or Breastfeeding
• Cardiac Pacemaker or Implanted Metal Devices
• Active Skin Conditions in the area (sores, psoriasis, eczema, rash), active herpes simplex virus (HSV), or a history of herpes labialis
• Use of Isotretinoin (Accutane) within the past 6–12 months

Use extra caution with a history of keloids or poor wound healing, active acne breakouts, and darker skin tones due to increased risk of adverse effects.

Cost, value, and comparisons

Secret RF pricing in South Korea

Typical per-session pricing ranges from $225–$600 USD (₩327,000–₩872,000). High-end clinics—especially in areas like Gangnam—may charge $1,000–$2,000 USD per session. Most patients need 3–4 sessions spaced 4–6 weeks apart, for a course total of roughly $675–$2,400 USD, with possible higher totals depending on clinic and plan.

Global cost comparison

Location	Average Cost per Session (USD)	Number of Sessions for a Full Course (min/max)	Estimated Total Course Cost (min/max)
South Korea	$225–$600	3–4	$675–$2,400
USA	$800–$1,100	3–4	$2,400–$4,400
Singapore	$300–$1,200	3–5	$900–$6,000
Canada	$600	3	$1,800
Australia	$420–$690	N/A	$1,260–$2,760 (est. 3–4 sessions)

Even at the higher end in Korea, costs are often far below U.S. rates. Combined with agency support, the overall package is a strong value for medical tourists.

How Secret RF compares to other treatments

RF Microneedling vs. Traditional Microneedling

Traditional microneedling triggers collagen via micro-injuries but lacks the added depth and heat of RF. Secret RF typically reaches deeper, addresses tougher scarring and mild laxity, and may achieve more with fewer sessions.

RF Microneedling vs. Fractional Laser

Fractional Laser can deliver dramatic results for severe scars and pigment but often requires more downtime and carries higher PIH risk for darker skin. Secret RF’s semi-insulated tips and shorter downtime (about 24–48 hours) make it broadly suitable. Some patients combine both for complementary benefits.

RF Microneedling vs. Chemical Peels

Chemical peels target surface issues like PIH, dullness, and mild marks. Secret RF treats deeper texture (pitted scars) and laxity by rebuilding from within. For mixed concerns, pairing Secret RF with peels can be comprehensive.

Treatment Modality	Mechanism of Action	Best for	Downtime	Suitability for Darker Skin Tones
Secret RF Microneedling	Combines microneedles with RF heat to remodel skin from within.	Atrophic scars (rolling, boxcar), skin laxity, uneven texture.	Minimal (24–48 hours).	Yes; generally safe with lower PIH risk.
Fractional Laser	Uses laser energy to create micro-injuries and resurface the skin.	Severe acne scars, deep wrinkles, significant sun damage.	A few days to a week or more.	Requires caution due to higher PIH risk.
Chemical Peel	Exfoliates outer layers to reveal fresh skin.	Surface concerns, hyperpigmentation, mild acne, fine lines.	Varies by peel strength.	Depends on peel; PIH risk if not chosen carefully.
Traditional Microneedling	Creates micro-channels to stimulate collagen.	Mild to moderate texture, fine lines, minor scars.	Minimal (24–48 hours).	Yes; safe for all skin tones.

Conclusion

Secret RF Microneedling is a well-supported option for improving Forehead Acne Scars, especially rolling and boxcar types. South Korea offers strong value, experienced providers, and a smooth medical tourism pathway. Expect gradual improvement over several sessions with careful aftercare. Choose a skilled practitioner to tailor settings, manage risks, and optimize results.
