How does laser hair removal treatment work?

For many people seeking silky smooth, stubble-free skin, laser hair removal has become the preferred alternative to daily shaving or monthly waxing sessions. Laser devices produce a highly concentrated beam of light at a specific wavelength that targets the pigment inside hair follicles. The laser emits photons attracted to the melanin pigment naturally present in hair.

This light is converted to heat energy, which damages the follicle enough to stunt further hair growth, but leaves the surrounding skin unharmed. This thermal damage to the hair germ cells prevents the follicle from producing new hair after shedding the current one. Multiple wavelengths of laser light are used, with settings tailored based on the client’s skin and hair color. For example, a wavelength of 755 nm may be optimal to target dark hair on light skin. The laser device delivers rapid lights to each area, typically lasting just milliseconds.

How many treatments are needed?

  • Hair growth cycles are not synchronized, making dormant follicles difficult to notice.
  • Not all follicles absorb enough energy to be fully disabled. Subsequent treatments target previously missed or stubborn follicles.
  • Dormant follicles may eventually become active again and produce new hair growth.

Most patients require between 3 to 7 sessions spaced 4-6 weeks apart to achieve up to 90% long-term hair reduction. Maintenance sessions may be recommended once or twice per year after the initial treatment course ends.

Process step-by-step

  1. The treatment area is thoroughly cleaned before excess hair is trimmed to just above the skin’s surface.
  2. To prevent your eyes from being damaged by laser light, safety eyewear will be provided.
  3. The practitioner will first test laser pulses on a small area to calibrate the optimal settings for your hair color and skin tone.
  4. The handheld device will deliver pulses of laser light to the target area in a grid-like pattern to ensure full coverage.
  5. Multiple passes will likely be made over each section, with a cooling device used simultaneously to minimize discomfort.
  6. Treatment time depends on the size of the area but can range from just a few minutes for the upper lip to over an hour for full legs.
  7. Ice packs and anti-inflammatory creams are often applied to soothe any temporary redness and swelling around the hair follicles.

Optimizing treatment results

Avoid plucking, waxing, or electrolysis for 6 weeks prior – this disrupts the hair follicle and interferes with the laser targeting it. Steer clear of tanning beds and minimize sun exposure during treatment. Tanning disperses the melanin pigment we want the laser to target. Refrain from applying any lotions, makeup, deodorant, or creams near the Depilazione Laser Treviso treatment area on the day of your appointment. The area should be clean and dry for optimal laser penetration.

Follow your clinician’s post-care instructions, which may include anti-inflammatory creams, aloe vera gel, and avoiding hot showers for a day or two. It helps soothe the area and prevent complications. Use sunscreen on the treated area for at least a month after each session. UV exposure irritates laser-treated skin. With a carefully administered laser protocol, you finally achieve your goal of smooth, stubble-free skin that feels soft and silky every day.
