Laser hair removal is a popular procedure that uses pulses of laser light to destroy hair follicles. This causes long-term hair reduction and in some cases permanent hair removal. But how exactly does laser hair removal work and what effects does it have? Here we’ll explore the impacts of laser hair removal on tattoos, hair follicles, moles, facial hair, skin, ingrown hairs, pain levels, permanency, and overall benefits.
Laser hair removal involves utilizing a potent laser or intense pulsed light (IPL) for eliminating undesired hair. This specialized light heats and eliminates hair follicles beneath the skin, hindering future hair growth. Typical treatment areas include the face, chest, legs, arms, underarms, and the bikini line.
Tattoos contain pigments similar to the melanin pigment that gives hair its color. So in theory, laser pulses targeting melanin could potentially blur or lighten a tattoo.
However, most tattoo inks actually reflect rather than absorb light. So there is minimal risk that laser hair removal will significantly fade or damage a tattoo. Still it's best to avoid directing laser pulses directly over tattoos whenever possible. Covering tattoos during treatment provides extra protection.
Potential Fading: Laser hair removal can cause fading or lightening of tattoo colors, especially if the ink contains dark pigments like black or dark blue.
Discoloration: The absorption of laser energy by the tattooed skin can lead to discoloration of the tattoo, altering its appearance.
Risk to Darker Inks: Tattoos with darker ink colors are at a higher risk of being affected by laser hair removal treatments.
Possible Impact on Lighter Inks: While less common, lighter-colored tattoos might also be impacted, but the risk is usually lower compared to darker inks.
Need for Caution: It's crucial to consult with a certified laser technician or dermatologist to assess the risks and potential impact on the tattoo before proceeding with laser hair removal in tattooed areas.
Adjusting Laser Settings: Professionals may adjust laser settings or recommend alternative hair removal methods to minimize the risk of damaging or altering the appearance of the tattoo.
The laser energy delivered during laser hair removal targets the pigment inside hair follicles. This creates heat damage and destroys follicles so they can no longer grow hair. Destroying the stem cells that regenerate hair growth provides long-term or even permanent hair reduction over time. After a series of treatments, most clients see a significant and lasting reduction in hair regrowth.
Absorption of Light: The hair follicles absorb the concentrated beam of light emitted by the laser.
Targeting Melanin: The pigment (melanin) in the hair follicles absorbs the laser's energy.
Heat Damage: The absorbed light energy converts to heat, damaging the hair follicles.
Inhibition of Hair Growth: The damaged follicles are unable to sustain normal hair growth.
Reduction in Hair Growth: Over time and with multiple sessions, the inhibited follicles result in reduced or delayed hair growth in the treated area.
Laser hair removal can be a concern when it comes to treating areas with moles. Moles are clusters of pigmented cells, and the concern with laser treatment near moles is the potential risk of damaging or changing the mole's appearance. Here's what happens when laser hair removal is used near moles:
Risk of Damage: Laser energy can be absorbed by the pigment in the mole, potentially causing changes to its appearance or structure.
Potential for Darkening or Lightening: In some cases, the mole might darken or lighten after laser treatment, altering its appearance.
Monitoring Required: It's essential to monitor moles closely before and after laser treatment to watch for any changes in size, shape, color, or other irregularities that might indicate a problem.
Consultation is Crucial: Before undergoing laser hair removal near moles, it's important to consult with a dermatologist or a qualified professional. They can assess the risk and provide guidance on whether treatment in those areas is safe or advisable.
In many cases, practitioners might avoid treating directly over moles or use specialized techniques to protect them during laser hair removal to minimize the risk of adverse effects on the moles.
Facial hair responds very well to laser hair removal. The thin skin and vellus hairs of the female face make this area ideal for permanent hair removal. Men's thicker facial hair may require more treatments but still achieves excellent reduction. Precise devices with small laser spots work best to avoid skin damage. For most clients laser hair removal effectively reduces facial hair growth long-term after 4-6 treatments.
Laser pulses target pigment in hair follicles without damaging the surrounding skin. However, misdirected laser energy can burn the epidermis leading to redness, blistering, scabbing and possibly scarring. Technicians must properly adjust settings and carefully manipulate devices to avoid skin injuries during treatment. Possible temporary side effects include redness, swelling, irritation and other reactions. Proper care after treatment helps skin heal quickly.
Ingrown hairs form when strands curl back under the skin instead of growing straight out of follicles. They often become inflamed and irritated. The laser destroys hair follicles and prevents regrowth, eliminating recurring ingrown hairs in treated areas. Exfoliating between sessions helps further prevent ingrown hairs. Removing the hair source ultimately provides the best solution.
Laser hair removal effectively reduces hair growth on all body areas. Any location can be treated except for the eyes and delicate regions. Tougher hair on the legs, arms, underarms and bikini line responds best. Laser settings must be adjusted based on treatment area and skin tone. Lighter skin and darker coarse hair provides maximum laser absorption for long-term hair destruction.
Most clients describe the sensation of laser hair removal as a quick pinching or snapping feeling to each pulse. This minor discomfort level doesn't require anesthesia. The most reported pain usually comes from treating sensitive areas like the upper lip, bikini line and underarms. The laser pulses are only a fraction of a second so there is no extended discomfort. Cooling the skin first helps decrease these stinging sensations.
Laser hair removal essentially damages hair follicle cells to prevent re-growth. Destroying the stem cells that regenerate hair provides long-term hair reduction. FDA-approved hair removal lasers have shown clinical permanency rates between 10% - 50% depending on hair/skin type after an average of 4-6 sessions. Repeating treatments provides better results. While not guaranteed, most people who complete treatments enjoy permanent reduction in hair growth.
Each client's results for laser hair removal can vary based on hair thickness, treatment areas and consistency of sessions. But clinical studies follow people 5-10 years showing long-term hair reduction is possible. Body areas with thicker hair growth may show more regrowth over time versus finer hair. Being consistent with repeat treatments provides longer lasting results. For many people, completing 4-6 sessions properly spaced leads to permanent reduction.
The biggest advantage of laser hair removal is providing a long-term or even permanent reduction in unwanted hair growth. It also works for people frustrated with frequent shaving, waxing, plucking or other temporary methods. The precision of lasers can selectively target dark coarse hairs without damaging the surrounding skin. So treatment avoids cuts, irritation or ingrown hairs common with shaving and waxing. The speed and accuracy of modern devices makes the procedure more convenient and comfortable than in the past. If done properly, laser hair removal delivers smooth, stubble-free skin for years after the last treatment.
In closing, today’s advanced laser hair removal devices can safely provide precise energy targeting to achieve long-term hair reduction. When performed correctly by skilled technicians, laser hair removal stops unwanted hair regrowth without damaging the skin or existing tattoos and moles. This allows enjoying smooth clear skin on the face and body for years after completing treatment series.
