5-Wavelength LED Phototherapy for Advanced Skin Regeneration

Breaking the Trade-off: The Dual-Mode Laser Solution

Aesthetic lasers have long faced the challenge of balancing efficacywith precision and safety. While traditional picosecond lasers canrapidly and effectively remove pigmentation, they are notrecommended for delicate skin or patients with darker complexions.Long-pulse lasers, while safer, struggle to effectively eliminatestubborn pigmentation and tattoos. It is precisely this conundrumthat has spurred the development of the dual-mode picosecond-long-pulse laser system.

This innovation transcends mere technical versatility;it directlyaddresses the demand for a 'one-stop' skin solution. The systemthoroughly eradicates stubborn pigmentation while gently restoringdelicate skin, delivering long-lasting anti-ageing benefits.

I. Two Pulsation Modes, Two ‘Superpowers’

1. Picosecond Mode: Precision Demolition, Fragmenting Pigmentation Imperceptibly

The picosecond mode delivers peak energy in an instant, shattering target tissues such as melanin granules into nanoscale particles through photomechanical effects. Much like employing high-precision bomb disposal tools, it dismantles problematic structures without harming surrounding healthy skin. The benefits are clear: first, more thorough clearance, as macrophages can readily metabolise these minute particles; second, significantly reduced risks of post-inflammatory hyperpigmentation and scarring, coupled with a shorter recovery period.

2. Long Pulse Width Mode: Gentle Heating, Root-Cause Improvement

The long-pulse width mode employs selective photothermal action to deliver controlled thermal damage to target tissues like hair follicles and abnormal blood vessels. This gradually deactivates problematic structures, allowing the body to naturally metabolise them. Its gentle nature broadens its applications: it effectively treats telangiectasia and soothes redness without irritation; during full-body hair removal, even heat distribution minimises discomfort, enabling treatments to be completed during a lunch break. Notably, its core 1064nm wavelength is particularly suitable for deeper skin tones (Fitzpatrick types IV-VI), effectively preventing post-treatment hyperpigmentation.

3. The True Advantage of Combining Two Modes: 1+1 Exceeds 2

One might ask: why not use two separate devices? While feasible, this approach yields slightly inferior results and precision. The advantage of integrating both systems lies in their shared optical path. Operators need only change the handpiece and settings to switch between intensive localised hair removal and gentle hair reduction, eliminating the need for patients to visit multiple clinics or endure lengthy recalibration sessions. It excels at coordinating precise treatments with straightforward recovery. For instance, when patients present with both freckles and telangiectasia, both treatment modes can be combined within a single session or delivered in two phases—across two or multiple sessions. This approach maintains treatment efficacy while minimising skin exposure.

Pigmentation concerns: This therapy demonstrates significant efficacy for freckles, sunspots, and Nevus of Ota, while also offering benefits for melasma. In most cases, mild freckles respond within 1 to 3 sessions, though deeper Nevus of Ota lesions may require additional treatments.

II. Which concerns are best addressed by this treatment?

Picosecond mode targets stubborn imperfections

· Pigmentation issues: Demonstrates significant efficacy on freckles, sunspots, and Nevus of Ota, while also providing supplementary improvement for melasma. Superficial freckles typically show marked improvement after 1-3 sessions, whereas deep Nevus of Ota requires a more systematic course of treatment.

· Tattoo Removal: Effective on black, green, blue, and red tattoos, with optimal results for black ink. Yellow tattoos require additional sessions due to complex pigmentation.

· Acne Scar Repair: For mild to moderate atrophic acne scars, the picosecond fractional mode stimulates collagen regeneration, gradually smoothing depressions. Compared to traditional CO₂ fractional lasers, it offers faster recovery and milder post-treatment reactions.

· Anti-ageing & Brightening: Activates dermal collagen and elastic fibres to diminish fine lines and pores, imparting a luminous, dewy complexion post-treatment.

Long Pulse Mode excels in ‘Gentle Rejuvenation’

· Facial Telangiectasia/Redness: Gently seals abnormal blood vessels to restore even skin tone, particularly effective for persistent redness caused by rosacea or sensitive skin.

· Full-body hair removal:Covers underarms, legs, upper lip, bikini line and more. 808nm or 1064nm wavelengths precisely target hair follicles for long-lasting results.

· Deep anti-ageing: Promotes collagen restructuring through gentle thermal action, addressing skin laxity, nasolabial folds and crow's feet. Minimal downtime with no disruption to daily life.

III. Comprehensive Treatment Guide: Pre-treatment, During Treatment, Post-treatment, Precautions, Contraindications

Preparatory Work: Follow these three steps to enhance treatment efficacy.

1. (1) Examination and Assessment: Seek diagnosis from a qualified practitioner. Ideally, utilise diagnostic tools such as a dermatoscope or VISA device to examine skin condition, identify specific issues and their types, and check for contraindications (e.g., skin infections, pregnancy, recent use of photosensitising medications).

(2) Personal Preparation: Avoid direct sunlight for one month prior to treatment and schedule sessions outside menstrual periods. Discontinue photosensitising medications as directed by your practitioner. Maintain a light diet and regular sleep patterns in the days preceding treatment to stabilise skin condition.

(3) Pre-treatment preparation: Thoroughly cleanse skin on the day of treatment, removing all cosmetics and sunscreen. Wear protective eyewear. For highly sensitive skin, apply a topical anaesthetic 30-60 minutes prior to treatment.

2. Treatment experience: Essentially pain-free with manageable sensations.

The practitioner will adjust treatment parameters according to your skin condition. Picosecond pulses produce a slight clicking sound and warmth. Longer pulses may also generate warmth. Mild redness at the treatment site is normal. Each session typically lasts from a few minutes to one hour.

3. Post-treatment care: Apply ice or cold compresses for 20–30 minutes. Apply a medical-grade recovery mask and growth factor gel to reduce inflammation and redness.

Precautions

Short-term care: Avoid exposing the skin to water for three days following treatment. Do not rub scabs; allow them to fall off naturally, which may take 6-8 days. Should the skin break, apply antibiotic ointment to prevent infection.

Long-term care: Strictly avoid sun exposure! It is advisable to use sunscreen (SPF 30 or higher) and other physical barriers to shield the skin from sunlight for the next two to three months. Refrain from hot showers, saunas, strenuous exercise, maintain a light diet, and ensure adequate rest.

Treatment Contraindications

Open wounds or infections at the treatment site, skin prone to keloid scarring, autoimmune conditions (lupus erythematosus, psoriasis), a history of photosensitive epilepsy, use of photosensitising medications (e.g., isotretinoin) within the past 3-4 months, severe systemic diseases (heart disease, liver disease, kidney disease), pregnancy or breastfeeding, or active melasma.

This treatment must be administered by licensed clinics and trained practitioners. Adjusting the settings is more crucial than selecting the machine itself. Even when using the same laser, two different practitioners may achieve entirely different outcomes. Melasma should be treated with low-energy lasers; high-energy lasers may exacerbate the condition. Individuals with darker skin tones must use a 1064-nanometre wavelength laser rather than 755 nanometres, as the latter may cause pigmentation.

IV. It is not merely a versatile instrument, but an entirely new aesthetic philosophy.

The popularity of picosecond dual-mode lasers fundamentally reflects our pursuit of beauty treatments that are ‘safe, efficient, and convenient’. We no longer wish to endure lengthy recovery periods for procedures, nor accept treatments limited to addressing single concerns. Through technological synergy, it overcomes the limitations of traditional lasers, enhancing the patient experience while maintaining medical professionalism. It not only fulfils the diverse needs of beauty seekers but also provides clinicians with more efficient solutions.

Finally, a reminder: the core principle of any aesthetic medical procedure is suitability for the individual. If you have concerns such as pigmentation removal, hair reduction, or anti-ageing, it is advisable to consult a specialist clinician to determine whether this versatile device is appropriate for your skin condition.

Safety is the prerequisite for beauty enhancement. Only by choosing the right approach and finding the right people can one truly achieve ‘effective and healthy beauty transformation’!
