PFB (Pseudofolliculitis Barbae, i.e. ingrown hairs, razor bumps or beard bumps) is an irritating condition that is commonly caused by shaving. It often appears in patients of darker skin types, including tanned skin and skin types IV through VI. The laser selectively targets melanin in the underlying hair and follicle, as well as hyperpigmentation surrounding the lesion. Due to LightPod lasers’ unique 650-microsecond pulse duration being 50 to 500 times shorter than pulses durations typically used for hair removal by other laser technologies, the energy passes through the skin quickly and does not overheat the epidermal melanin to effectively treat the condition.
How many treatment sessions are required?
This can vary depending on skin and hair color, but generally 4 to 6 sessions are required for 80% clearance or greater, which is considered very good in aesthetic laser medicine. After that, an annual maintenance treatment is recommended.
How does this treatment work on PFB (ingrown hairs)?
The laser energy is absorbed by pigment in actively growing hair, damaging the hair follicle and thus, hair regrowth is impeded, reducing and eliminating the bumps caused by ingrown hairs.
Do I need to use topical anesthesia? What about gels?
No. Anesthetics and cooling gels are not needed with LightPod lasers, because 650-microsecond technology makes it uniquely pain-free. This unique benefit saves time, cost and mess by eliminating gels and sprays required by other lasers that cool the skin during treatment.
Is it painful?
No, there is just a mild, very tolerable sensation of heat. This is one of the key technical breakthroughs of Aerolase technology! LightPod lasers have set a new standard for virtually pain-free treatment, even on darker skin types, thanks to MicroPulse-1064 technology. This unique benefit saves time, cost and mess by eliminating gels and sprays required by other lasers that cool the skin during treatment.
Do the hairs fall out? If so, when?
If the laser lens and fluence setting are chosen correctly, many hairs will singe upon contact with the laser beam and will disappear. Some hairs which are in a dormant growth phase will not respond at all, although some of them will be damaged even if they did not singe. Those which are damaged may fall out within a few days after treatment or even immediately if the treatment site is rubbed.
Is it permanent, or do the hairs grow back?
The FDA requires that laser manufacturers describe the process as “permanent hair reduction”, not “permanent hair removal”, because, in their words, “although laser treatments with these devices will permanently reduce the total number of body hairs, they will not result in a permanent removal of all hair.” Patients can generally expect more than 75% to 80% clearance after 6 sessions and should plan on 1 or 2 annual follow up sessions for ideal maintenance.
Can it be used on dark skin?
Actually, LightPod lasers are the safest laser in the industry for darker skin types or tanned skin. This is because of 650-microsecond technology, which essentially eliminates treatment pain while minimizing the chances of hyper and/ or hypo-pigmentation.
Can it be used on blond or gray hair?
There is no light based hair removal technology which is efficient on blond or gray hair because melanin is the primary target or chromophore in LHR, so treatment efficacy is typically much lower if the hair is low in melanin (like gray or blond hair).
