Laser Hair Removal: What it is, how can you prepare, and what you can expect
Laser hair removal is a medical procedure harnessing concentrated laser light to eliminate unwanted hair effectively.
How it Works
In laser hair removal, a laser emits light that gets absorbed by hair pigment (melanin). This light transforms into heat, targeting the hair follicles within the skin and impairing their ability to produce hair, thus delaying future growth.
Long-lasting but Not Permanent
While laser hair removal significantly delays hair growth, it's not a guarantee of permanent removal. It requires multiple sessions initially and ongoing maintenance. Although it's most effective for individuals with light skin and dark hair, advancements now allow its use on all skin types.
Why Opt for Laser Hair Removal
People turn to laser hair removal to reduce unwanted hair, commonly on legs, armpits, upper lip, chin, and the bikini line. However, it can be applied to almost any area except around the eyelids or on tattooed skin.
Factors Affecting Success
Success hinges on hair color and skin type, where hair pigment should absorb the light while sparing the skin. Contrasting dark hair and light skin yield the best results. The risk of skin damage is higher when there's little contrast.
Possible Side Effects
Laser hair removal might lead to temporary skin irritation, redness, and swelling. Changes in skin pigment can also occur, which might be temporary or permanent. Severe side effects like blistering or scarring are rare but possible.
Preparation
When considering laser hair removal, consult with a board-certified doctor experienced in your skin type. Avoid facilities where non-medical personnel administer the procedure.
Pre-treatment
Before the procedure, follow your doctor's advice to minimize sun exposure and avoid darkening skin. Discontinue hair removal methods like plucking or waxing, and ask about medication restrictions.
The Procedure
Each session lasts around two to six treatments, depending on hair growth speed. Protective goggles are worn during treatment, and a topical anesthetic may be applied for comfort.
During the Procedure
The doctor will use a handheld laser device, applying cooling measures to protect the skin. You may feel warmth and cold sensations during the procedure.
After the Procedure
After treatment, there may be redness and swelling. Applying ice and, if needed, a steroid cream can alleviate discomfort. Avoid sun exposure, tanning beds, and use SPF30 sunscreen daily for six weeks.
Results
Results aren't immediate, with hair shedding over days to weeks. Multiple sessions are required due to hair growth cycles. Hair often regrows finer and lighter, requiring maintenance treatments.
Home Laser Devices
Home laser hair removal devices are available, but their effectiveness compared to professional treatments remains uncertain. These devices have cosmetic status, and their safety hasn't been extensively studied.
If opting for a home laser device, closely follow the provided instructions to minimize risks, particularly eye injuries.
Conclusion
Laser hair removal is an effective solution for unwanted hair, offering long-lasting results, but not necessarily permanent removal. Consult with a qualified professional for personalized guidance and safe treatment.
