Hyperpigmentation—whether from sun exposure, hormonal melasma, or old acne marks—is one of the most persistent skin concerns among patients visiting Dr. Sadia's Advanced Aesthetic & Laser Clinic in Banani. Traditional lasers often struggled to treat pigment safely on medium to deep skin tones common in Bangladesh, sometimes worsening dark marks instead of clearing them.
Pico Laser technology solves this problem by delivering ultra-short picosecond energy pulses—trillionths of a second—that shatter pigment particles into microscopic dust without generating excess heat in surrounding tissue.
How Pico Laser Clears Pigment Safely
Rather than heating and damaging the skin like older nanosecond lasers, Pico Laser uses a photomechanical effect to fragment melanin clusters into tiny particles that the body's own lymphatic system naturally clears over the following weeks.
1. Minimal Thermal Risk: The photomechanical (rather than photothermal) action makes Pico Laser significantly safer for darker Fitzpatrick skin types prone to post-inflammatory hyperpigmentation.
2. Treats Multiple Pigment Concerns: Effective against melasma, sun spots, freckles, stubborn acne dark marks, and even certain tattoo pigments.
3. Bonus Collagen Stimulation: The laser's mechanical shockwave also triggers mild collagen and elastin remodeling, gradually improving overall skin texture, fine lines, and enlarged pores alongside pigment clearing.
4. Pore & Scar Refinement: Using a specialized fractional lens, Pico Laser can also be adjusted to address acne scarring and pore size in the same treatment series.
What Happens During a Session
After cleansing and applying numbing cream if needed, the laser handpiece is passed over the treatment area in a grid pattern. Most patients describe the sensation as a light snapping or tingling feeling, and a full-face session takes about 20 to 30 minutes.
Treatment Course
Melasma and deeper pigmentation typically require 4 to 6 sessions spaced 3 to 4 weeks apart, while superficial sun spots may clear in 1 to 3 sessions. There is minimal to no visible downtime, though strict daily sunscreen use is essential to prevent pigment rebound, especially in Dhaka's high-UV climate.
Why Melasma Needs a Careful, Gradual Approach
Unlike simple sun spots, melasma is hormonally influenced and can flare with excess heat or aggressive treatment. Dr. Sadia uses conservative, lower-fluence settings for melasma cases specifically to avoid triggering a rebound flare, combined with supportive skincare between sessions.
