Laser Toning — Pastelle Q-Switched Nd:YAG
The Pastelle laser is a dual-wavelength 1064 and 532 nm Q-switched Nd:YAG laser that delivers nanosecond pulses absorbed by melanin particles, shattering them for natural elimination by the body. The low-fluence, multi-session toning mode is indicated for melasma and deep hyperpigmentation, while the 532 nm mode targets freckles and brown spots. As a non-ablative treatment, it offers rapid recovery; however, improper parameters may worsen melasma.

Mechanism
Ultra-short laser pulses are selectively absorbed by melanin, shattering pigment particles via a photoacoustic effect without overheating surrounding tissue; the immune system then clears the fragments over several weeks. The 1064 nm wavelength penetrates deeply into the dermis with minimal interference from hemoglobin and superficial melanin, making it suitable for deep pigmentation and darker skin tones. The 532 nm wavelength targets more superficial layers with high absorption, making it ideal for epidermal brown spots and freckles.
How does Toning differ from Spot Treatment?
Laser toning sweeps across the entire treatment area using low fluence, a large spot size, and multiple sessions (typically 6–10 sessions spaced 2–4 weeks apart) to lighten diffuse pigmentation such as melasma and dark marks—aiming for gradual skin tone evening without scabbing. Spot treatment delivers high enough energy directly to individual freckles or brown spots, causing them to darken, form micro-crusts, and peel off within 5–10 days, usually over 1–3 sessions. Mistakenly using the spot treatment mode on melasma is a primary cause of severe melasma rebound.
Indications
Epidermal and mixed melasma (combined with topicals and sun protection), persistent deep post-acne marks, freckles, sun spots, uneven skin tone, support for enlarged pores and oily skin, and mild erythema reduction. Not all pigmentary conditions respond: congenital nevi, tattoos, and certain severe post-inflammatory hyperpigmentations require a separate clinical evaluation.
Potential Risks
Guttate hypopigmentation (white spots) from overly frequent sessions or excessive fluence—often difficult to reverse; melasma rebound or worsening due to incorrect laser parameters; transient post-inflammatory hyperpigmentation; and mild, transient urticaria lasting a few hours. This is why laser toning must be performed by a dermatologist who examines the skin, classifies the condition, adjusts the parameters accordingly, and monitors progress using standardized clinical photography at every session.
At BonBoz
Dermatologists examine the skin using a Wood's lamp to differentiate between epidermal and dermal melasma and distinguish freckles from sun spots. They prescribe accompanying topicals and sun protection, customize parameters for each facial zone, and monitor progress via standardized photos. The procedure is performed directly by the dermatologist; the treatment plan will be paused or adjusted if the skin does not respond as expected.

Chuyển hướng khi đáp ứng kém
Một số loại nám đáp ứng kém với toning — bác sỹ đánh giá lại thay vì làm thêm buổi.
When should you see a doctor?
- Nám của bạn có thể là loại đáp ứng kém với toning — cần soi da và phân loại trước, tránh làm nhiều buổi vô ích.
- Da đang viêm, có tổn thương hở hoặc vừa cháy nắng.
- Không thể tránh nắng nghiêm ngặt — điều kiện bắt buộc, nếu không nám dễ đậm trở lại.
- Đang mang thai, hoặc nám xuất hiện cùng thay đổi nội tiết chưa được đánh giá.
How is it performed?
Cleansing the face and applying protective eye shields. Laser Toning: the physician delivers low-energy laser passes evenly across the treatment area — lasting 15–20 minutes, with a mild warming and tingling sensation, typically without requiring topical anesthesia. Spot Treatment: targeting individual spots, with a sensation similar to a snapping rubber band; topical anesthesia can be applied. Following this, the skin is cooled, soothed, and protected with sunscreen.
Before the procedure
Avoid sun exposure and tanning for 2 weeks prior; discontinue topical retinoids 3–5 days before; inform the clinic of any photosensitizing medications, history of herpes, or current pregnancy; thoroughly remove all makeup.
After the procedure
Laser Toning: Mild erythema may last for a few hours. Normal activities can be resumed immediately. Apply broad-spectrum SPF 50 sunscreen. The next session is scheduled in 2–4 weeks. Spot Treatment: Treated spots will darken and form scabs for 5–10 days — do not pick or scratch, apply strict sun protection, and use prescribed topical medications. Avoid physical exfoliants and chemical peels for 1 week.
Possible risks — your doctor explains them before treatment
- Punctate hypopigmentation (white spots) due to excessive sessions or energy levels — difficult to reverse
- Melasma rebound or spreading if inappropriate settings are used
- Temporary post-inflammatory hyperpigmentation (PIH), especially following spot treatment on darker skin tones without sun protection
- Mild redness and transient urticaria lasting a few hours
- Melasma treatment aims for control and management, not complete eradication
Who should NOT have this?
- Recent sunburn or recent tanning
- Currently taking photosensitizing medications (certain antibiotics, isotretinoin) without completing the required washout period
- Currently pregnant (postpone treatment)
- Active herpes infection or active dermatitis in the treatment area
- Pigmented lesions suspected of malignancy that have not been medically evaluated and ruled out
- Expectations of complete melasma clearance after only a few sessions, or inability to adhere to strict sun protection
