Pigmentation, dullness, enlarged pores, acne scars – these skin concerns trouble too many people. Whether it’s sunspots from UV exposure, age spots that come with time, or the most stubborn melasma (chloasma), traditional brightening serums and skincare products often only work at the surface level with limited results. While conventional lasers are effective, their “photothermal effect” can cause heat accumulation that may inadvertently damage surrounding healthy skin, leading to side effects like hyperpigmentation or hypopigmentation. The enLIGHTen Pico laser, widely used in Korean dermatology clinics in recent years, is an advanced picosecond device designed specifically for Asian skin types, using “photoacoustic waves” instead of “photothermal” energy. Manufactured by the US‑based company Cutera, it has received FDA clearance and approval from Japan’s Ministry of Health, Labour and Welfare. This article will systematically walk you through the core principles of enLIGHTen Pico, suitable candidates, price references for mainstream treatment options, the complete treatment journey, duration of results, and potential risks – giving you all the key information in one place so you can make a rational choice.
To understand why enLIGHTen Pico delivers better results with fewer side effects, it’s essential to grasp the fundamental difference between traditional lasers and picosecond lasers.
Traditional Q‑switched (nanosecond) lasers rely on a “photothermal effect” – using thermal energy to “burn” melanin particles. This process is like using high heat to shatter large rocks, but heat dissipates into surrounding tissue, easily damaging normal skin – which is why traditional lasers often cause hyperpigmentation, hypopigmentation, or scarring.
enLIGHTen Pico operates completely differently. Its pulse duration is extremely short – 750 picoseconds (1 picosecond = one trillionth of a second) – which is 1,000 times faster than traditional nanosecond lasers. At such short pulse durations, the laser energy does not have time to convert into heat; instead, it generates a powerful “photoacoustic effect” (or photomechanical effect). In simple terms, it’s like using ultrasound to instantly shatter large stones (pigment particles) into ultra‑fine dust, which the body then naturally eliminates.
What’s more impressive is enLIGHTen’s flexible design with dual wavelengths (532nm and 1064nm) and dual pulse durations (750 picoseconds and 2 nanoseconds). The 532nm wavelength targets superficial pigment (such as freckles and sunspots), while the 1064nm wavelength penetrates deeper to address deep‑seated pigment (like melasma) and tattoo ink. When equipped with the MLA focusing lens (golden honeycomb tip), the laser creates countless microscopic “vacuoles” (LIOB effect) in the dermis without damaging the epidermis, physically loosening scar tissue and stimulating massive new production of collagen and elastin. This is why enLIGHTen not only fades spots but also improves pores, fine lines, and acne scars at a deeper level.
enLIGHTen Pico has a very wide range of applications, mainly targeting the following groups:
However, not everyone is suitable. Absolute contraindications include: implanted pacemakers or other electronic medical devices; pregnancy and breastfeeding; severe skin diseases or immune system disorders; active infections or open wounds in the treatment area.
enLIGHTen Pico treatment modes are mainly divided into 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, zero downtime | ~30,000 – 80,000 |
| Pico Fractional (single full‑face) | Enlarged pores, fine lines, acne scars | MLA focusing lens, stimulates collagen, progressive results | ~100,000 – 250,000 |
| Pico Spot / Tattoo Removal (single) | Stubborn spots, multi‑colour tattoos | High‑energy concentrated treatment, significant results | ~80,000 – 200,000 (depending on area) |
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 wavelength (532nm or 1064nm) and treatment mode based on your 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 or show temporary whitening. Redness from Pico Toning typically subsides within minutes to hours; fractional mode may cause mild crusting that naturally sheds in about 3‑5 days. Most people can return to normal appearance within 2‑3 hours after treatment.
enLIGHTen Pico 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 fractional 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 enLIGHTen Pico 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 enLIGHTen Pico 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, which usually fades within about an hour.
Q: Are there side effects or long‑term risks?
A: The incidence of side effects with enLIGHTen Pico is far lower than with traditional lasers. Because the pulse duration is extremely short, heat dissipation is minimal, and thermal damage to surrounding tissue is nearly zero. Common short‑term reactions include mild redness and temporary crusting (fractional mode), usually resolving within hours to 5 days. With minimal thermal injury, the risk of hyperpigmentation or hypopigmentation is greatly reduced. In very rare cases, temporary pigmentation may still occur – proper post‑treatment sun protection is essential.
Q: What’s the difference between enLIGHTen Pico, PicoSure, and PicoWay?
A: All three are picosecond lasers, but each has its strengths. enLIGHTen from Cutera features adual‑wavelength (532nm/1064nm) + dual‑pulse (750ps/2ns)flexible design. PicoSure is known for its 755nm wavelength and honeycomb lens, while PicoWay offers three wavelengths (532nm/785nm/1064nm). enLIGHTen’s 1064nm wavelength is especially friendly to Asian skin – deep penetration with high safety.
Q: How soon can I wear makeup after enLIGHTen Pico?
A: You can apply makeup immediately after Pico Toning mode. For Fractional mode, it’s best to wait until crusts naturally shed (about 3‑5 days). Regardless of the mode, use gentle skincare products and avoid irritating ingredients post‑treatment.
Q: Is enLIGHTen Pico safe for Asian skin?
A: Yes, enLIGHTen Pico is very suitable for Asian skin. Its 1064nm wavelength offers adequate penetration depth with optimal melanin absorption – providing higher safety for darker skin types or those prone to hyperpigmentation compared to other wavelengths. It has received FDA clearance and approval from Japan’s Ministry of Health, Labour and Welfare.
As a next‑generation picosecond laser device, enLIGHTen Pico 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 light crusting (Fractional) may occur; in very rare cases, temporary hyperpigmentation may develop, especially in darker skin types; understand the associated risks before treatment; use sunscreen with SPF 30 or higher and avoid sun exposure after treatment.
To minimise risks, be sure to: choose a licensed Korean dermatology or aesthetic clinic that uses genuine enLIGHTen 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 – enLIGHTen Pico 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.
