The principle of 808 diode laser hair removal is based on selective
photothermolysis, a process that targets and destroys hair
follicles while leaving the surrounding skin and tissues unharmed.
The 808 diode laser is a specific type of laser technology used for
hair removal and has gained popularity due to its effectiveness and
safety.
Melanin Absorption: The 808 diode laser emits a specific wavelength
of light (around 808 nanometers) that is highly absorbed by the
melanin pigment present in the hair follicles. Melanin is the dark
pigment responsible for hair and skin color.
Targeting Hair Follicles: When the 808 diode laser is applied to
the skin, the melanin in the hair follicles absorbs the laser
energy. As a result, the laser energy is converted into heat
energy, which damages the hair follicles while leaving the
surrounding skin tissues unaffected.
Selective Destruction: The principle of selective photothermolysis
ensures that the laser targets only the melanin-rich hair follicles
without damaging the surrounding skin. This is because the duration
of the laser pulse is carefully controlled to match the thermal
relaxation time of the target (hair follicle) while allowing the
surrounding skin to cool down and remain undamaged.
Hair Follicle Damage: The absorbed laser energy heats up the hair
follicle, effectively damaging its structure. This damage disrupts
the hair growth process and inhibits further hair regrowth.
Hair Shedding: In the days and weeks following the treatment, the
damaged hair follicles will begin to shed the treated hair. This is
a natural process, and patients may notice hair falling out from
the treated area.
Hair Growth Reduction: With each subsequent treatment session, the
808 diode laser progressively reduces the number of actively
growing hair follicles in the treated area. The result is a
significant and long-term reduction in hair growth.
Picosecond laser tattoo removal is an advanced tattoo removal
technique that uses ultrashort pulses of laser light to break down
tattoo ink particles into smaller fragments. The principle behind
picosecond laser tattoo removal is based on the concept of
selective photothermolysis, similar to other laser tattoo removal
methods, but with even shorter pulse durations.
Ultrashort Pulses: The picosecond laser emits pulses of laser light
in extremely short durations, typically in picoseconds (trillionths
of a second). This ultrashort pulse duration allows for higher peak
power and energy, which is crucial for effective tattoo ink
fragmentation.
Selective Photothermolysis: The picosecond laser targets tattoo ink
pigments specifically. When the laser light is applied to the
tattooed skin, the high-energy pulses are absorbed by the tattoo
ink particles.
Ink Fragmentation: The intense energy delivered in picoseconds
creates a photomechanical effect, shattering the tattoo ink
particles into tiny fragments. These smaller ink particles are now
more manageable for the body's immune system to clear away.
Immune System Clearance: Once the ink particles are fragmented, the
body's immune system recognizes them as foreign substances and
starts the process of engulfing and eliminating them. The
fragmented ink particles are then gradually removed through the
lymphatic system.
Gradual Fading: Over several weeks following the picosecond laser
tattoo removal treatment, the body continues to flush out the
broken-down ink particles. As a result, the tattoo gradually fades
with each session.
The picosecond laser technology offers several advantages over
traditional Q-switched nanosecond lasers used for tattoo removal:
Faster Results: The shorter pulse durations of the picosecond laser
allow for more effective ink shattering, leading to quicker
clearance of tattoo ink.
Enhanced Efficacy: Picosecond lasers are effective for removing
tattoos with stubborn or resistant ink colors that might be
challenging for other lasers.
Reduced Side Effects: The ultrashort pulses minimize heat build-up
in the skin, reducing the risk of side effects such as scarring or
pigmentation changes.
Suitable for Various Ink Colors: Picosecond lasers can target a
broader spectrum of tattoo ink colors, including darker colors like
blue and green.
