How Lasers Work?

The primary principle of laser hair removal is selective photothermolysis (SPTL), the matching of a specific wavelength of light and pulse duration to obtain optimal effect on a targeted tissue with minimal effect on surrounding tissue. Lasers can cause localized damage by selectively heating dark target matter, melanin, in the area that causes hair growth, the follicle, while not heating the rest of the skin. Light is absorbed by dark objects, so laser energy can be absorbed by dark material in the skin, but with much more speed and intensity. This dark target matter, or chromophore, can be naturally-occurring or artificially introduced.

 

Melanin is considered the primary chromophore for all hair removal lasers currently on the market. Melanin occurs naturally in the skin, and gives skin and hair their color. Because of the selective absorption of photons of laser light, only black or brown hair can be removed. Laser works best with dark coarse hair. Light skin and dark hair are an ideal combination, being most effective and producing the best results.

Is Hair Removal Permanent with Laser Therapy?

Laser Hair Removal can permanently reduce 40%-80% of unwanted hair in the area treated. Various factors play a role in the effectiveness of the treatments & the results differ from person to person. Food and Drug Administration approved them as “permanent reduction” and not “permanent removal”. Hair removal lasers cannot and do not remove 100% of the hair in an area. With appropriate treatments, laser can remove most of the coarse hair on a body area, but cannot remove finer hair. Be cautious of clinics making claims that seem too good to be true.

How Do Lasers Work on Different Hair and Skin Colours?

Skin types are classified on Fitzpatrick scale from 1-6.
Best results: Fair skin [1-2] with dark hair
Worst results: Black skin [5-6] with gray hair.

White and gray hairs indicate the absence of melanin and laser hair removal is impossible.

What Are the Risks and Side-Effects?

Some normal side effects may occur after laser hair removal treatments, including itching, pink skin, redness, and swelling around the treatment area or swelling of the follicles (follicular edema). These side effects rarely last more than two or three days. The two most common serious side effects are acne and skin discoloration. Rare side effects include blistering, scarring and skin texture changes.

What Is the Cost of Laser Hair Removal?

The cost of laser hair removal may not appear too high of a price to pay in comparison with the price of waxing kits, expert waxing, and depilatories creams spent over time. When compared to the countless series of waxing and electrolysis sessions needed, laser hair reduction could be the best available choice. The actual laser hair removal costs are rational and need only a small commitment. The monthly maintenance costs of waxing and the time need for electrolysis essentially make the comparatively small price of laser treatments, the clear choice.

Tanned Skin and Laser Light Energy

People with tanned skin have been usually discouraged from traditional laser hair removal treatments because tanning changes their natural skin pigmentation. During a laser hair removal procedure, light energy is directed to the skin where unwanted hair is located. The skin absorbs some of the laser energy before it reaches the hair follicles. How much energy is absorbed will be determined by the skin color. Tanned skin will usually absorb excess amounts of light energy and can cause burning or discoloration after treatment. Therefore, to treat a tanned patient, the laser energy must be turned down to prevent burning. This, in turn, decreases the effectiveness of the light energy to kill unwanted hair follicles. After tanning you should wait for 4-8 weeks, depending on your skin colour, to start laser hair removal.

How Many Laser Treatments Will I Need?

Most clients need at least 6-8 effective treatments spaced 6-12 weeks apart dependent on the body area. Because hair grows in cycles, several sessions are needed in order to affect all hair on any given area. Hair cycle length varies depending on body parts. Face usually requires more frequent treatments (about 6-8 weeks apart) whereas legs and back need less frequent treatments (closer to 12 weeks apart). Due to length of hair growth cycles, treatments are usually needed once every 6-12 weeks.

What Should I Expect Before a Laser Treatment?

Clients should not wax, epilate, or remove hair with the root using any other hair removal method for at least 6 weeks prior to their first session and throughout their course of treatments. The hair needs to be in place in order to be targeted by laser as laser devices targets the pigment in the hair. In addition, it should be avoid of sunbath, tanning equipment and sun exposure for six weeks before and after treatment. Sun exposure makes laser hair removal less effective and makes complications after treatment more likely.

 

The area to be treated should be shaved 1-2 days prior to treatments so that the energy is targeted towards the hair follicle and not wasted it on the hair above the skin’s surface. Treating unshaven skin can result in burning of the skin by singed hairs.

What Happens After Laser Hair Removal Session?

Shedding of all treated hair should be probable within 3 weeks of each treatment. Once the hair sheds, patients should experience a hair-free period for several weeks. Once new hair comes in again, patients should come in for their next session.

 

The hair that doesn’t shed and is growing as usual after 3 weeks has likely been either missed or they would be in sleep period of hair growth cycle and now they are in fast growth phase. If this is the case, a touch-up treatment is necessary at that time. All 6-8 treatments should be effective treatments in order to achieve better results.

What Are the Post Care Treatments?

  • Applying an ice pack or cold compress to the treated area to decrease redness and swelling (can last 1- 48 hours).
  • Applying a SPF-30 sunscreen (UVA/UVB) to protect sun exposure for at least a week.
  • Not exercising; taking hot showers, or using hot tubs or saunas for 12-48 hours.
  • Not using tanning beds or exposing unprotected skin to sun between treatments.
  • Usage of makeup and deodorant with caution. Spot-test all products for 12-24 hours before application.
  • Feel free to shave between treatments.
