Why Choose 1927nm Thulium Laser For Acne Scars

There are a variety of devices and methods for treating acne scars, including photofacial rejuvenation, fractional laser, picosecond laser, microneedling, and chemical peels, which can improve red and black acne marks, pitted acne scars, and rough skin texture, respectively. Among them, 1927nm thulium laser technology is the latest option on the market. With its ultra-high water absorption coefficient, it precisely targets the epidermis and superficial dermis. It belongs to the "sub-ablative" fractional mode, which can stimulate collagen regeneration and smooth shallow acne scars like fractional lasers, and precisely metabolize pigment, lighten pigmentation and red marks like picosecond lasers. At the same time, it has a short recovery period, minimal thermal damage, and low risk of hyperpigmentation. It effectively makes up for the shortcomings of traditional fractional lasers, which have long recovery periods, and picosecond lasers, which have limited improvement on deep acne scars. It provides a safer, more efficient, and integrated solution for acne scars that takes into account skin tone and texture.

 

 

Acne scars are mainly divided into four categories:
Red acne marks: formed by capillary dilation after inflammation subsides
Black acne marks: dark marks left by pigmentation caused by inflammation
Pitted acne scars: depressions on the skin surface due to damage or loss of dermal tissue
Hypertrophic scars: raised and hardened skin due to excessive proliferation of fibrous tissue.

 

1927nm thulium laser is currently the latest generation of sub-ablative fractional technology for repairing acne scars. It offers highly effective, gentle results with a short recovery period, making it particularly suitable for Asian skin tones and mild to moderate acne pits and marks.

 

 

I. Core Effects (Clinical Data)

Atrophic Acne Scars: After 3 treatments (4-week intervals), ECCA scores decreased by an average of 15–20 points, an improvement rate of approximately 35%–40%, comparable to traditional 2940nm ablative lasers, but with less pain and a shorter recovery period.

Pigmented Acne Marks (Red/Black): **92.59%** of patients showed significant fading after 3 months of treatment, significantly better than glycolic acid (70.37%); it also improves skin texture and reduces enlarged pores.

Hypertrophic/Red Scars: Inhibits capillary dilation, softens fibrous tissue, and reduces protrusion and redness.

Safety: The adverse reaction rate is only 3.7%, mostly temporary redness and mild edema, which subside within 1-3 days, with no significant risk of scabbing or hyperpigmentation.

 

II. Advantages Compared to Traditional Fractional/Picosecond Lasers

Compared to Fractional Lasers (CO₂/2940nm): Recovery time is shortened from 7-14 days to 1-3 days, with less thermal damage and a lower risk of pigmentation, suitable for those concerned about downtime.

Compared to Picosecond Lasers: Picosecond lasers primarily target superficial pigmentation, offering limited improvement to deep acne scars; 1927nm can simultaneously stimulate dermal collagen regeneration, addressing both scar removal and pit filling for a more comprehensive effect.

Precise Target Layer: Energy is concentrated from the epidermis to the superficial dermis (200-300μm), precisely covering pigmentation, acne scars, and the collagen layer without damaging deeper tissues.

 

III. Suitable Candidates and Treatment Course

Optimal Indications: Mild to moderate atrophic acne scars, red/black acne marks, rough skin texture, and enlarged pores.

Not suitable for: Severe ice pick acne scars (requires combined ablative laser treatment), active acne, and acute phase of sensitive skin.

Treatment course: 3–5 sessions, spaced 3–4 weeks apart, with strict sun protection for 1–2 weeks post-treatment.

 

 

1927nm thulium laser works by leveraging the high absorption properties of water molecules. The laser energy is precisely absorbed by the skin's moisture, acting in a sub-ablative fractional pattern on the epidermis and superficial dermis. On one hand, it precisely breaks down pigment particles in acne scars, accelerating metabolism to fade pigmentation and redness; on the other hand, it minimally invasively stimulates the dermis, activating fibroblasts to promote the regeneration and reorganization of collagen and elastin fibers, filling in damaged tissue, smoothing pitted acne scars, and reconstructing skin structure to improve rough skin texture, thus achieving scar repair effects.

PicoSure Laser: $800–$1,800, recovery period 1–2 days, strong blemish reduction, weak filling effect.

 

 

I. Immediately after surgery (0–24 hours): Cooling and soothing + protection against heat stimulation

Cold compress: Immediately after treatment, apply a medical ice pack/cold compress (through gauze) for 15–20 minutes, repeating every 2–3 hours to reduce redness, burning, and slight swelling.

Avoid water and makeup: Avoid washing your face with tap water for 24 hours. Do not apply any skincare products or makeup to reduce the risk of infection and irritation.

Avoid heat: Strictly avoid washing your face with hot water, sauna, hot springs, and strenuous exercise (sweating will irritate the wound). Avoid high-temperature environments and sun exposure.

Normal reactions: Mild redness, heat, and tightness are normal and will subside within 24–48 hours.

 

II. Days 1–3 after surgery (acute phase): Gentle cleansing + intensive moisturizing

Cleansing: After 24 hours, you can use water/gentle amino acid cleanser (water temperature ≤37℃). Gently cleanse with your fingertips, without rubbing or scrubbing. After washing, gently pat dry with a clean, soft towel; do not rub.
Moisturizing and Repairing: Prioritize using medical-grade repair products (hyaluronic acid gel/dressing, recombinant human epidermal growth factor gel, ceramide lotion), applying a thin layer 2-3 times daily to keep skin hydrated and accelerate barrier repair.

Strict Sun Protection (Top Priority):

Absolutely avoid direct sunlight at midday (10:00–16:00) for one month.

Physical Sun Protection When Outdoors: Wide-brimmed hat, mask, parasol, sunglasses.

Sunscreen: Starting from the 3rd day after surgery, use an SPF50+, PA++++ physical sunscreen (containing zinc oxide/titanium dioxide), reapplying every 2-3 hours for 3-6 months to prevent pigmentation/darkening.

Contraindications: Do not scratch, pick at, or rub the skin; do not use alcohol, fragrances, acids (salicylic acid/glycolic acid), retinol, or exfoliating products.

 

III. Post-operative Days 4–7 (Repair Period): Consolidation and Repair + Gradual Resumption of Skincare

Peeling/Micro-scabs: A few people may experience slight peeling or thin scabs. Allow them to fall off naturally; never pick or peel them, as this can easily lead to scarring or pigmentation.

Moisturizing: Continue using medical-grade repair lotion/cream twice daily. Increase the frequency if skin feels dry and tight.

Skincare Recovery: After 7 days, gradually resume gentle daily skincare (moisturizing and repairing); consider resuming whitening and anti-aging products after 2 weeks (consult your doctor first).

Sun Protection Still Required: Skin remains sensitive at this stage; physical sun protection and sunscreen are essential.

 

IV. Post-operative Month 1 (Stabilization Period): Sun Protection + Stabilization + Avoidance of Superimposed Irritation

Sun Protection Must Be Maintained: Continue using SPF50 + sunscreen for 3 months; for those with pigmentation issues, 6 months is recommended.

Avoid Other Procedures: Avoid phototherapy, microneedling, chemical peels, and glycolic acid peels within 1 month to prevent further damage.

Lifestyle: Avoid staying up late, abstain from smoking and alcohol, and reduce consumption of spicy and irritating foods to minimize inflammation.

 

V. Common Abnormalities and Treatments
Redness persisting for more than 3 days, significant swelling, increased pain, oozing, or pustules: Contact a doctor immediately, as it may be an infection or allergic reaction.

Pigmentation (rebound hyperpigmentation): Often caused by inadequate sun protection. Strict sun protection combined with medical-grade whitening and repair treatments will usually result in fading within 1-3 months.

 

VI. Treatment Course and Follow-up Visits
Standard treatment course: 3-5 sessions, with each session spaced 3-4 weeks apart.

One week before each treatment: Discontinue retinol, acids, and exfoliation; avoid excessive sun exposure/tanning for two weeks prior to the procedure.
