The home RF category split in 2024 when Medicube released the Ultra Tune 40.68 at 40.68 MHz, per Medicube US (2026). LG's Pra.L Intensive Multi-Care BLP1 stacks RF with microcurrent, sonophoresis, iontophoresis, and cooling in one Y-shaped body, per BTY ALY (2024).

RF frequency — Medicube wins on raw depth, LG wins on layered stack

Medicube's Ultra Tune 40.68 runs at exactly 40.68 MHz, per Medicube US (2026). That's the ISM-band frequency used in some professional dermatology systems.

LG does not publish a frequency number for the BLP1. Marketing materials describe "Volumizing RF Therapy" without spec sheets, per BTY ALY (2024). The trade-off is depth versus breadth.

A 2025 randomized controlled study in Lasers in Surgery and Medicine confirmed monopolar RF devices reach the dermis and remodel collagen safely at home, per Wang et al. (2025). Medicube's published frequency lets buyers verify the claim. LG asks for trust.

Verdict: Medicube wins on transparency. LG wins if you value an undisclosed proprietary stack tuned for one device.

Price — Medicube wins by a wide margin

Medicube Ultra Tune 40.68 lists at $530 on the official US site and around $499 on Amazon, per Amazon (2026). YesStyle shows ~$485 with frequent promotions, per YesStyle (2026).

LG BLP1 has no US retail price. Grey-market eBay and Asian resellers list it between $1,200 and $1,800 depending on currency and shipping, per eBay listings (2026). In Korea via Olive Young, the device retails around ₩1,490,000 (~$1,080).

The price gap is roughly 2x to 3.4x. For most US buyers, that's the entire conversation.

Verdict: Medicube under $600 versus LG at $1,200 minimum. Buyers outside Asia rarely overcome that delta.

Modes and technologies — LG wins on stack breadth

The LG BLP1 fuses five technologies: RF, microcurrent, sonophoresis, iontophoresis, and cooling, per Geek Culture (2024). Three heads handle different jobs.

Medicube Ultra Tune 40.68 combines RF with microcurrent and 5 LED modes, per Medicube US (2026). Simpler stack, single head.

LG's iontophoresis improves topical absorption. Medicube relies on RF heat for the same goal. Both work — LG just packages more vectors into one device.

Verdict: LG wins for shoppers who want one device to replace four. Medicube wins for shoppers who think feature creep dilutes RF dose.

Session length and frequency — Medicube wins on daily-use flexibility

Medicube recommends 5–10 minute sessions, 1–3 times per day, per YesStyle (2026). Short, repeatable, low-friction.

LG BLP1 runs a fixed 12-minute protocol three times weekly, per BTY ALY (2024). Voice guidance walks the user through three steps in sequence.

Daily users favor Medicube. Routine-driven users who treat skincare as a scheduled ritual favor LG.

Verdict: Medicube wins on flexibility. LG wins if you prefer a guided, fixed protocol.

Conductive gel — Medicube wins on convenience

Medicube Ultra Tune 40.68 works without a special gel. Your existing serum or moisturizer is enough, per Medicube US (2026).

LG BLP1 requires a conductive gel or water-based serum to glide and conduct RF properly, per Geek Culture (2024). LG sells its own gel; third-party hydrogels also work.

That's a small recurring cost for LG owners — about ₩30,000 (~$22) per 100ml tube. Medicube avoids it.

Verdict: Medicube wins on day-to-day cost and friction. LG wins if you already use a hydrating gel anyway.

Body coverage — Medicube wins on versatility

Medicube allows full-body use. The device works on jawline, cheeks, forehead, arms, abdomen, and thighs, per Medicube US (2026). A six-tip ergonomic head glides smoothly.

LG BLP1 is designed for face and eye contour only. Heads are sized for facial use, per Geek Culture (2024).

For buyers wanting one device to cover face plus body areas like the upper arms or stomach, Medicube is the only choice between these two.

Verdict: Medicube wins for body care. LG wins for buyers who only need a face tool.

US availability — Medicube wins; LG is import-only

Medicube ships to the US directly with Amazon Prime support, per Amazon (2026). Warranty applies. Customer service is in English.

LG BLP1 is not officially distributed outside Asia. eBay sellers list grey-market units without warranty support in the US, per BTY ALY (2024).

If your unit fails, Medicube replaces it. LG buyers ship to Korea or accept the loss.

Verdict: Medicube wins for US, EU, and APAC buyers outside Korea. LG wins only in markets where it has official distribution.

Clinical evidence and safety — tie, both lean on category-level data

Neither device has published peer-reviewed clinical trials under its own name. Both rest on the broader RF safety record.

A 2024 trial in the Journal of Cosmetic Dermatology found home-use RF safe over 8 weeks for facial rejuvenation in 22 women aged 25–60, per Ai et al. (2024). A 2025 RCT confirmed monopolar RF for skin tightening, per Wang et al. (2025).

A 2017 study found home RF + light combo devices safe and tolerable for periorbital wrinkles over 12 weeks, per Gold et al. (2017). Both Medicube and LG inherit this safety profile.

Verdict: Tie. Neither brand publishes its own RCT, but RF as a category is well-supported.

Brand depth — LG wins on manufacturing scale

LG Electronics has run Pra.L since 2017 with patented Volumizing RF Therapy and clinic-grade R&D, per LG HK (2024). The device is built in LG's home-appliance facilities.

Medicube launched the AGE-R line in 2022 and reports +37.5% type III collagen secretion in 7 days from internal testing, per Korea Experience (2026). It is the Korean K-beauty market leader by device unit sales.

Brand depth matters most for resale value and long-term parts support. LG wins on engineering pedigree; Medicube wins on category focus.

Verdict: LG wins for long-term durability assumptions. Medicube wins for category-specific product velocity.

User-reported results — tie, both deliver after 8–12 weeks

CNN Underscored reviewed the Medicube AGE-R Booster Pro and called it a meaningful daily-use device for absorption and contour improvements, per CNN Underscored (2024). Reader's Digest noted visible single-use brightening, per Reader's Digest (2024).

The LG BLP1's published outcome data shows 100% skin tone improvement and 92% inner-skin-density gain over 6 weeks of twice-weekly use, per Daily Vanity (2024). Self-reported reviewer outcomes describe less fatigued, firmer skin.

Both devices need 8–12 weeks before users notice lift around the jaw and crow's-feet. Neither is instant.

Verdict: Tie. Real outcomes track consistency, not which brand you bought.

Bottom line

If you live in the US and want one RF device that travels, treats face and body, and costs under $600 — Medicube AGE-R Ultra Tune 40.68. If you live in Korea, Japan, or Hong Kong, want LG's multi-tech protocol, and have $1,200+ — LG Pra.L Intensive Multi-Care BLP1.

Both products work. The price gap and US availability tip the daily decision toward Medicube for most readers, per the 2025 monopolar RF efficacy data, per Wang et al. (2025).

Frequently asked questions

Is the Medicube AGE-R FDA cleared? No. The AGE-R Ultra Tune 40.68 is sold as a consumer cosmetic device, not a medical device. The LG Pra.L Derma LED Mask variant carries US FDA clearance for LED, but the BLP1 RF device is not FDA-cleared for the US market.

Can I use both devices in the same routine? Yes, but space sessions by at least 30 minutes. Layering RF tools in a single sitting raises skin temperature beyond manufacturer guidance and offers no added benefit, per category-level evidence in Aesthetic Surgery Journal (2024).

How long until I see results? Plan 8–12 weeks of consistent use before judging either device. Collagen remodeling from RF builds slowly. Single sessions may give brief plumping; sustained tightening needs months.

Are these devices safe for sensitive skin? RF heat can irritate compromised skin. Patch-test on the jaw first. Both brands recommend skipping use immediately after retinoids, peels, or sun exposure.

Which device holds resale value better? LG BLP1 holds value better in Asian secondhand markets due to limited availability. Medicube holds value better in the US thanks to brand recognition and retail presence on Amazon.
