How Does Laser Hair Removal Work?

Oh, those unsightly hairs! Not even a week passes after you have had a tedious session of shaving or waxing that the hair reappears – but this time feeling thicker and coarser than before. This is one of the biggest limitations of traditional hair removal methods; they are bothersome and need constant maintenance. No wonder a good percentage of women, and men, are switching to permanent solutions such as laser hair removal.

Laser hair removal is a non-invasive, safe, and effective aesthetic procedure to remove unwanted hair from the face, hands, legs, chin, underarms, back, bikini line, and other areas. The precision, speed, and effectiveness of laser hair removal have fueled the demand. It is likely the global laser hair removal market size will reach $2.51 billion by 2031, growing at a CAGR of 15.7% from 2022 to 2031.    

But what’s the hype all about? Why is laser considered one of the best hair removal methods today?

Laser Hair Removal Procedure

Laser treatment for hair removal works based on a process known as selective photo thermolysis. The process uses a concentrated beam of laser light absorbed by the melanin in your hair. The light energy produces heat, which tends to damage the hair follicles. This delays or inhibits hair growth in the future.

Multiple laser hair removal sessions are required initially, along with maintenance treatments to get effective results. Safe and FDA-approved treatment methods such as Diolaze XL may require 4-6 treatments to deliver long-lasting results. However, you can expect results after the first session – the hair will grow finer and thinner, and the skin will appear smoother. With each additional session, the results will be more visible and impressive.   

How to Prepare for Laser Hair Removal?

Your provider will give you preparation instructions, which can help improve the efficacy of laser treatment and minimize risks. Here are some things to keep in mind:

• It is important to stay out of the sun and prevent tanning for at least 1-2 months before treatment.
• Do not consume anti-inflammatory drugs, such as aspirin, which may cause blood thinning.
• Avoid hair removal methods such as electrolysis, waxing, or plucking at least 4 weeks before the treatment. These can disturb your hair follicles, hindering the effects of laser treatment.
• Shaving or trimming is suggested one day before the procedure. It helps remove the hair above the skin, preventing burnt hairs or damage to the surface skin when exposed to heat from laser light. However, the hair shaft remains intact and enables the procedure performance seamlessly.

What to Expect During the Procedure?

The procedure involves using a hand-held laser instrument to press into your skin and activate the laser. Only a small portion of the skin is treated at a time. When the laser activates, a beam of light will pass through the skin and into the hair follicles. This produces intense heat that damages the hair follicles and inhibits hair growth in that area.

The process may cause a little discomfort, and the heat may feel like a warm pin prick, though it is safe for the skin. To reduce the sensation, your provider may use a cooling gel, or if done with DiolazeXL, the device will include a cooling tip.

After the Procedure

While laser hair removal has no potential side effects, you might notice swelling or redness immediately after the procedure. To minimize the discomfort, you can apply ice to the area being treated. If you get a skin reaction after hair removal, though chances are low, your provider may apply a steroid cream to the areas.

After the procedure and in between sessions, avoid exposure to direct sunlight. Make sure you apply sunscreen daily with at least SPF30. Do not use things like a tanning bed for 6 weeks or as your provider recommends.

The Final Words

Laser hair removal is an effective and safe aesthetic treatment that delivers proven results for most people. Make sure you get the procedure done by an experienced healthcare provider. Book an appointment with an aesthetic expert and get smooth, hair-free skin to look your best.
