Laser hair removal is a beauty solution that destroys your hair from the roots permanently or for a longer period of time and saves lot of time, efforts and pain.

In waxing, the hair is ripped off the skin but the hair grows back. However, in laser treatment the hair follicles are damaged and the growth cycle is interrupted. It is one of the most commonly used techniques in U.S and has started making waves across the globe as an effective hair removal solution.

Laser technique is preferred for face, leg, arm, underarms, bikini line and other areas. The treatment time depends upon the area of the skin taken. It is a medical procedure which requires trained and highly-skilled professionals for the best outcome. So, if you plan to get lasered, here is all what you need to know to make it worth that time, pain and cost.

How Does Laser Hair Removal Work?

The procedure straight away targets the pigment in the hair follicles with a concentrated beam of light. When the roots situated at inner layers of the skin heats up, the pigment named melanin absorbs all the heat which eventually damages the sacs (hair follicles) and hair bulbs within the skin that produces hair.

The destruction reduces future hair growth or stops the hair-growth completely. This results in silky smooth skin and a fresh feel. The cool gel like ointment is applied onto the skin before starting the treatment to protect outer layers (epidermis) from being damaged by heat.

It is said that the best combination for this procedure is dark coloured hair and light skin. The reason being that the dark skin which is said to have greater melanin/pigment might get burns due to heating up of pigments. And also, if one has lighter hair, the laser won’t be as effective as it in case of darker hair.

How to Prepare for Laser Hair Removal?

Cost of laser hair removal

  • Avoid sun exposure a few weeks before and after the method- UV-rays makes the treatment less effective.
  • Shave your hair just a day before appointment so that the energy reaches to the base and not to the extra length of hair
  • Consult your skin specialist before indulging
  • Go for reputed and well-known salons only
  • No plucking and waxing between the treatments because it uproots hair on temporary basis. While laser hair removal is something that target the roots. So, for the procedure to be effective it is required to have normal hair growth.
  • Laser with longer wavelengths are recommended. Long pulsed Nd Yag laser is used for dark skin.

Laser Hair Removal Vs IPL

IPL stands for Intense Pulsed Light and is similar to laser in terms of destructing the hair growth cycle. But based on the wavelength of light used and the ability of destruction, both procedures are slightly different from each other. Unlike concentrated beam, a broad spectrum of high-intensity light is used to kill the hair in IPL method. The light is emitted from the device at multiple wavelengths unlike a single focussed beam of laser treatment.

IPL is also said to be cheaper as compared to laser technique. Also, IPL works best for those who have dark and thick hair because dark and thicker hair absorbs the light better and hence the outcome is better. But at the same time it is not safe for dark skin tone because heating of pigments means greater risks of skin burn.

No wonder IPL is highly effective but just because there is a shallow penetration it may require greater number of treatment sessions. The key difference lies in the technology used to generate light. Laser goes deeper into the skin with a single beam of light and produces fast results.

Laser Hair Removal Side Effects

Laser hair removal technology is tried and tested for over years (approx 20 years as per studies) before being commercialized. Naturally, there is a peace of mind associated with the therapy. Also, the technique is FDA approved and a safe procedure but potential consequences should never be ruled out.

While there is absolute relief from hair emerging back, the technique comes at its own risks. For majority of people there are no health risks or side risks associated. But a few may experience different types of issues. Also, it is different with each skin type, tone and adaptability.

  • Hyper and Hypo pigmentation: While the former darkens the skin, the latter lighters the skin tone. So, the procedure tampers with your original skin tone. Hypo is more common and happens to people with dusky complexion.
  • Burns and irritation
  • Redness or skin being tender.
  • Cancer is also associated with this technique
  • Skin irritation
  • Skin crusting on treated area

In most of the cases, symptoms are short-lived and don’t pose any health risks as such. It is advisable to see your dermatologist before and after the treatment.
