Description

A dermatologic laser treatment using 1550 nm wavelength to create microscopic thermal zones in the dermis without epidermal ablation, stimulating collagen remodeling for skin resurfacing and scar reduction.

Main Uses

Primary clinical uses include: non-ablative skin resurfacing for atrophic acne scars (especially rolling and shallow boxcar types), improvement of photodamaged skin (fine lines, dyspigmentation, texture irregularities), mild to moderate facial rhytides, striae distensae (stretch marks), and melasma stabilization (as adjunctive therapy). It is indicated for Fitzpatrick skin types I–IV, offers minimal downtime (24–72 hr erythema/edema), and stimulates dermal collagen/elastin remodeling via controlled microthermal zones (MTZs) without epidermal ablation.

Normal Range

Non-ablative fractional laser (1550 nm) is not a diagnostic laboratory test with numerical 'values' or quantitative biomarkers; it is an energy-based aesthetic/therapeutic procedure. Therefore, there is no conventional 'normal range' of numerical values (e.g., mg/dL or IU/mL). Instead, clinical safety and efficacy depend on device-specific parameters—including fluence (typically 15–70 mJ/microbeam), density (100–400 microbeams/cm²), pulse duration (1–50 ms), and number of passes—selected based on skin type (Fitzpatrick I–IV), indication, and treatment goals. No standardized universal numeric reference range applies.

Low Values - Possible Causes

N/A — This is not a biochemical or hematologic assay; 'low values' do not apply. However, suboptimal clinical outcomes (e.g., insufficient collagen remodeling or poor response) may result from: (1) Inadequate fluence or density settings, (2) Insufficient treatment sessions or improper interval spacing (e.g., <4 weeks), (3) Improper patient selection (e.g., Fitzpatrick V–VI skin without adjusted protocols), (4) Poor post-procedure skincare compliance (e.g., sun exposure, lack of moisturization), (5) Presence of active inflammation or untreated melasma.

High Values - Possible Causes

N/A — This is not a quantifiable lab test; 'high values' are not defined. Adverse events resembling 'over-treatment' may occur due to: (1) Excessive fluence or density leading to prolonged erythema, edema, or crusting, (2) Overlapping pulses or excessive passes causing thermal injury, (3) Treatment on tanned or photosensitized skin, (4) Concurrent use of topical retinoids or exfoliants within 5–7 days pre-treatment, (5) Device calibration errors or operator inexperience resulting in unintended energy delivery.
