Picosecond laser (referred to as Pico Laser for short) is considered the most advanced laser technology on the market today, helping to solve skin defects with extremely short pulses without invasiveness, without surgery. So what does the Pico laser do ? How is the application? What are the pros and cons of this beauty method?

What is Pico Laser?

Pico laser is the latest technology in the treatment of melasma, freckles, tattoo removal, skin rejuvenation, acne scars and other pigmented problems with short treatment time and high efficiency. Pico Laser technology is capable of producing laser beams with extremely short pulse durations measured in picoseconds (10-12 seconds). Pico lasers have different wavelengths such as 532nm, 755nm, 1064nm to help target accurately while limiting damage to surrounding normal tissues.

What effect does Pico laser have in today's life?

Pico laser has the effect of helping to solve many skin imperfections, including

Melasma is a common hyperpigmentation disorder that mainly affects women. Women are more likely to get melasma when experiencing situations such as hormonal changes due to pregnancy, hormone replacement therapy, or birth control pills. Melasma usually appears on the face but can also sometimes appear on the neck, chest, and forearms.

3. Skin rejuvenation

Pico laser corrects conditions such as wrinkles, crow's feet, improves large pores, ... helps rejuvenate the skin to bring youthfulness and radiance, especially on dark skin types. Pico Laser technology delivers energy pulses deep to the dermis, creating bubbles in this layer, in order to stimulate the production of collagen and elastin to help fill wrinkles, crow's feet, ... bring elasticity. resilient, firm.

  • The scar tissue is stimulated to produce collagen, elastin and realigns the dermis structure to improve skin firmness and fill the scar tissue.

The advantage of Laser Pico in the treatment of acne scars helps to shorten the recovery time and the cases that have failed with previous methods. Especially on people with pigmentation problems or dark skin, the Pico Laser is a safe option that limits the possibility of post-inflammatory hyperpigmentation when treating acne scars.

How does the Pico laser work?

The Pico laser works by delivering extremely short pulses of energy, limiting its ability to radiate heat to the areas that need to be treated precisely. The action of the Pico laser breaks the problematic skin pigmentation into many microscopic fragments, which are then absorbed and eliminated by the body naturally. Pico laser technology results in fast, effective, highly selective treatment of pigmented lesions and tattoos.

In addition, Pico Laser penetrates deep into the skin to help boost collagen and elastin production, resulting in smooth and firm skin. In addition to the ability to improve scars and smooth imperfections, the Pico Laser method also helps skin rejuvenation in reducing wrinkles, crow's feet, ... bringing firm texture, brighter skin tone and regaining freshness. young.

The Pico laser determines the target extremely accurately, allowing for optimal photomechanical effects. Although the energy pulses have a high frequency, the effects of the Pico Laser are gentle on the outer layer of the skin. Pico treatments do not burn the skin, and patients experience less discomfort during the treatment.
