In Korean dermatology clinics, PicoSure (Fraxel Pico /蜂巢皮秒) is an unmistakable name. Manufactured by the US‑based Cynosure, it is the world’s first picosecond laser device to receive FDA clearance. Unlike traditional lasers, PicoSure delivers energy in picosecond‑level (one trillionth of a second) ultra‑short pulses, shattering melanin through a “photoacoustic effect” rather than a “photothermal effect” – like using ultrasonic waves to shatter large rocks into dust, which the body then naturally eliminates. PicoSure uses the 755nm alexandrite wavelength, which has exceptionally high melanin absorption – three times that of 1064nm – while having extremely low blood absorption. This allows for “precise targeting of melanin without damaging surrounding tissue.” Whether it’s freckles, sunspots, melasma, dull skin, acne scars, or enlarged pores, PicoSure offers an effective and safe solution. This article will comprehensively walk you through the principles, suitable candidates, treatment options and prices, procedure experience, duration of results, and potential risks – giving you all the key information you need to make a rational choice.
PicoSure’s core advantages come from three technological breakthroughs.
First, picosecond‑level ultra‑short pulses. Traditional nanosecond lasers use a “photothermal effect” to destroy melanin – using heat to “burn” pigment particles. However, heat dissipates into surrounding tissue, easily damaging normal skin and causing side effects like hyperpigmentation or hypopigmentation. PicoSure’s pulse duration is extremely short (750 picoseconds) – the energy doesn’t have time to convert into heat, instead generating a powerful photoacoustic effect that shatters melanin into ultra‑fine dust‑like particles. Thermal damage is minimal, and side effects are greatly reduced.
Second, the 755nm “golden wavelength.” 755nm is the alexandrite laser wavelength, which has exceptional selectivity for melanin – its melanin absorption rate is three times that of 1064nm, while its haemoglobin absorption rate is extremely low. This means it can precisely target melanin without damaging blood vessels or surrounding tissue – making it especially suitable for Asian skin types prone to pigmentation.
Third, the Focus Lens Array (蜂巢瞬效透镜). When equipped with the Focus Lens, the laser energy is focused into countless microscopic beams, creating a “LIOB effect” (laser‑induced optical breakdown) in the dermis – without damaging the epidermis, it physically stimulates massive new production of collagen and elastin fibres. This is why PicoSure not only fades spots and brightens skin but also simultaneously improves enlarged pores, fine lines, and acne scars.
PicoSure has received FDA clearance for indications including pigmentation, tattoos, acne scars, wrinkles, and melasma. Specifically, it is suitable for the following groups:
However, not everyone is suitable. Absolute contraindications include: pregnancy and breastfeeding; severe skin diseases or immune system disorders; active infections or open wounds in the treatment area; photosensitivity or current use of photosensitising medications.
PicoSure treatment modes are mainly divided into the following three types, targeting different skin concerns:
Below is a comparison of these options with reference prices (in KRW):
| Option | Best for | Features | Reference price (KRW) |
|---|---|---|---|
| Pico Toning (single full‑face) | Dullness, superficial spots, routine maintenance | Low energy, large area, gentle brightening, virtually no downtime | ~150,000 – 250,000 |
| PicoSure + Focus Lens (single full‑face) | Enlarged pores, fine lines, acne scars, deep pigment | Focus Lens stimulates collagen, progressive results | ~250,000 – 500,000 |
| Pico Spot / Tattoo Removal (single) | Stubborn spots, multi‑colour tattoos | High‑energy concentrated treatment, significant results | ~200,000 – 400,000 (depending on area) |
Note: Prices above are reference ranges for the Korean market. Actual pricing varies by clinic and doctor qualification – please refer to your in‑person consultation.
Your choice should be made after discussing your skin concerns and budget with a dermatologist.
Pre‑procedure preparation: On your first visit, the doctor conducts a consultation, assessing your skin type, depth of pigmentation, and areas for improvement. Your face will be thoroughly cleansed to remove makeup and skincare products. Some clinics apply a topical anaesthetic cream before treatment to enhance comfort.
During the procedure: The doctor selects the appropriate mode based on your treatment plan. During treatment, you may feel a mild tingling sensation or a feeling like a rubber band lightly snapping against the skin. Treatment time varies by area – full‑face treatment typically takes 20‑30 minutes, while spot or tattoo removal is quicker.
Immediately after: Your skin may appear slightly red after treatment. Redness from Pico Toning typically subsides within a few hours; redness from Focus Lens mode may last about 24 hours. Most people can resume daily activities immediately after treatment.
PicoSure results unfold in three phases: Immediate effect (right after treatment) – your skin instantly looks brighter, more radiant, and feels smoother – a visible change from the gentle treatment of the surface layer.
Progressive effect (1‑4 weeks post‑treatment) – as pigment particles are gradually eliminated by the body, spots fade and skin tone becomes more even. Collagen regeneration stimulated by Focus Lens mode also begins to show during this phase – pores refine and skin elasticity improves.
Stabilised effect (1‑3 months) – collagen regeneration peaks, and overall skin texture improvement reaches its best state. For deep pigmentation like melasma, multiple sessions are usually needed to achieve ideal results.
The duration of PicoSure results varies by individual. Superficial spots show significant improvement after 1‑2 sessions; melasma and acne scars are typically recommended a full course of 3‑5 sessions. Treatment intervals are 3‑4 weeks apart, allowing sufficient time for skin repair and metabolism. With good sun protection, results can be maintained for a long time.
Q: Is PicoSure painful?
A: During treatment, you may feel mild tingling or a gentle snapping sensation. Most clinics apply a numbing cream beforehand for a comfortable experience. After treatment, there’s only mild redness and warmth – most people experience no significant discomfort.
Q: Are there side effects or long‑term risks?
A: The incidence of side effects with PicoSure is far lower than with traditional lasers. Most people experience no adverse reactions after treatment. A small number may have diffuse erythema and oedema, usually resolving within1‑3 days; very few may experience purpura or bruising, typically resolving in1‑2 weeks; some may have mild tenderness when washing the face, usually disappearing within7‑10 days. With minimal thermal injury, the risk of hyperpigmentation or hypopigmentation is greatly reduced.
Q: What’s the difference between PicoSure and PicoWay (Ultra Pico)?
A: Both are picosecond lasers, but they follow different technological approaches. PicoSure uses the755nm wavelength + Focus Lens, which has exceptionally high melanin absorption – making it especially suitable for Asian skin and pigmentation concerns. PicoWay uses three wavelengths (532nm/785nm/1064nm) for broader applications. PicoSure’s 755nm wavelength is particularly friendly to Asian skin, with a lower risk of post‑inflammatory hyperpigmentation.
Q: How soon can I wear makeup after PicoSure?
A: You can apply makeup immediately after Pico Toning mode. For Focus Lens mode, it’s best to wait until redness subsides (usually within 24 hours). Regardless of the mode, use gentle skincare products and avoid irritating ingredients post‑treatment.
Q: Is PicoSure safe for Asian skin?
A: Yes, PicoSure is very suitable for Asian skin. The 755nm wavelength has exceptional selectivity for melanin, with low thermal damage and lower risk of hyperpigmentation. It has received FDA clearance and is internationally recognised by dermatologists as a preferred choice for spot removal and skin brightening on Asian skin. In terms of safety, picosecond lasers are significantly superior to traditional nanosecond lasers.
As a next‑generation picosecond laser device, PicoSure has a far better safety profile than traditional lasers. However, as a medical aesthetic procedure, the following points should be noted: mild redness (Pico Toning) or temporary erythema/oedema (Focus Lens) may occur; in very rare cases, temporary hyperpigmentation may develop, especially in darker skin types; understand the associated risks before treatment and practise strict sun protection afterwards.
To minimise risks, be sure to: choose a licensed Korean dermatology or aesthetic clinic that uses genuine PicoSure equipment; fully disclose your skin history to the doctor, including any photosensitivity, melasma history, and recent sun exposure; practise strict sun protection post‑treatment – this is key to maintaining Pico results and preventing pigmentation; be realistic about results – PicoSure is an “improvement” treatment, not a “magic” cure. For pigmentation and scars, a full course of sessions is needed to achieve ideal results. For stubborn issues like melasma, typically 3‑5 sessions are required. Be patient and complete the course, while maintaining daily sun protection and hydration – that’s how you truly achieve the desired improvement.
