The Booster Pro is MEDICUBE’s most popular device worldwide — and for good reason. It packs four professional technologies into one palm-sized tool. Think of it as the “starter kit” for Korean at-home skin care. If you’ve never used a skincare device before, this is the one.

🔬 Technology Deep-Dive

EMS (Electro-Muscle Stimulation): Delivers low-level electrical pulses that contract and relax facial muscles — the same principle used in clinical microcurrent and EMS devices. Think of it as a “workout” for the 43 muscles in your face. With consistent use, the muscles regain their natural lifted position, reducing sagging along the jawline, cheeks, and eye area.

LED Therapy (Red + Near-Infrared): Red light (630–660nm) penetrates the dermis and stimulates fibroblasts to produce collagen and elastin. Near-infrared light (800–850nm) goes deeper, improving circulation and accelerating cellular repair. This is the same technology used in $400-per-session in-clinic LED treatments.

Electroporation: Uses gentle electrical pulses to temporarily open microchannels in the skin barrier, allowing active ingredients in your serum to penetrate up to 10× deeper than normal topical application. This is why MEDICUBE always pairs device use with their Collagen Serum or Hyaluronic Acid essence.

1. Cleanse thoroughly. Remove all makeup, sunscreen, and impurities. Your skin needs to be perfectly clean for the electrical currents to work properly.
2. Apply conductive serum. Use a generous layer of MEDICUBE’s Collagen Serum or any water-based essence. The device requires moisture on the skin to conduct EMS safely and effectively. Do NOT use on dry skin.
3. Select your mode. The Booster Pro has 3 intensity levels. Start at Level 1 for your first 2 weeks. Tingling or mild twitching is normal — that means EMS is working.
4. Move in upward, outward strokes. Glide the device from chin toward ear, from nose toward temple, from forehead up toward hairline. Always work against gravity. Spend 30–45 seconds on each zone.
5. Focus extra time on problem areas. Jawline, nasolabial folds, and under-eye area benefit most. Hold the device gently in place for 10–15 seconds on these spots.
6. Finish with LED mode. Switch to LED-only for a final 3–5 minutes over the whole face, especially under eyes and forehead. This locks in the lifting effect and stimulates collagen.
7. Apply your moisturizer and SPF. The electroporation has opened your skin channels — your skincare will absorb better than ever right after treatment.

📅 Realistic Results Timeline

If the Booster Pro is a daily gym workout for your face, the Ussera Deep Shot is the deep structural renovation. This device uses focused ultrasound energy — the same foundational technology as clinical Ultherapy (HIFU) — to create thermal coagulation points deep within the skin’s SMAS layer. The result? Stimulated collagen that rebuilds from the inside out.

🔬 What “SMAS Layer” Means for Your Skin

The SMAS (Superficial Musculo-Aponeurotic System) is a layer of tissue just beneath the dermis — the same layer that surgeons target in facelift procedures. Most topical skincare, including serums and creams, cannot reach this layer. Focused ultrasound can. By delivering precise thermal energy to the SMAS layer at a depth of 3.0mm–4.5mm, the Ussera triggers the body’s natural wound-healing response: collagen regeneration. The lifting effect is structural, not superficial.

1. Start with perfectly cleansed skin. Remove all makeup, SPF, and skincare. The ultrasound coupling gel (included) needs to contact skin directly.
2. Apply the coupling gel generously. This is not optional — it creates the acoustic bridge between the device and your skin so ultrasound energy can penetrate without discomfort or interference.
3. Select the correct cartridge depth. The Ussera comes with cartridges for different depths (1.5mm, 3.0mm, 4.5mm). Start with 3.0mm for general lifting. Use 1.5mm around the delicate eye area only.
4. Work in defined lines. Glide slowly from chin to ear, cheekbone to temple, and forehead hairline, in linear passes. Maintain consistent contact — don’t press too hard or lift off mid-stroke.
5. Treat each zone systematically. Left cheek → right cheek → chin/jaw → forehead → neck (if desired). Each zone takes about 2–3 minutes.
6. Complete 1–2 full passes per session. One pass = one complete glide across each zone. More is not better. Ultrasound creates thermal points — you are literally heating collagen fibers to stimulate repair.
7. Remove gel and apply calming serum. Skin may be slightly warm or flushed for 20–30 minutes. This is normal. Follow with centella asiatica serum or hyaluronic acid to soothe and hydrate.

Enlarged pores are one of the top skin concerns for women in their 40s and 50s. In Korean clinics, “pore care” is its own treatment category — and the ATC Pore Shot brings that expertise home. It combines aqua suction (to draw out sebum and debris) with radiofrequency energy (to tighten pore walls) in a single device.

1. Steam your face for 5 minutes or apply a warm towel to open pores before starting. This dramatically improves the suction step’s effectiveness.
2. Fill the water reservoir with the provided mineral water or distilled water. This is what creates the aqua peel effect.
3. Set suction to Level 1 for sensitive skin, Level 2–3 for normal/oily skin. Glide in upward strokes across T-zone, nose, and chin — never hold in one spot for more than 2 seconds (bruising risk).
4. Switch to RF tightening mode and move in circular motions over treated areas. The RF energy heats the dermis around pores, causing a gentle contraction that temporarily (and over time, structurally) reduces pore size.
5. Finish with the pore-cooling mode if available — the contrast of heat then cool is the same “open-then-close” principle Korean estheticians use for pore facials.
