laser hair removal pore size for face

Your pores may make your skin appear oily and congested, making you self-conscious and uncomfortable. An effective laser treatment for pore size reduction such as the HALO hybrid fractional laser could help minimize this unfavorable effect on your appearance.

Most people know that laser hair removal works to destroy hair follicles; however, it also works to improve skin texture and tone by working its magic on skin tones. When performed by trained medical personnel in a clinic setting, laser hair removal is safe treatment option.

Spot size is an integral component of laser hair removal. This refers to the distance from which a light beam travels into your skin; for treatments on common treatment areas like your face/neck or bikini area, 1 cm2 spot size provides precise treatments with maximum effectiveness.

Diode laser technology offers an effective solution to this problem; longer wavelengths used by diode laser technology are less reliant upon epidermal melanin for targeting, and are therefore better at penetrating deeper into skin where bulb and follicle targets can be more effectively targeted. Especially effective is 1064nm wavelength specifically developed to effectively treat darker skin types including African-American patients.

Diode laser technology uses longer pulse durations that help ensure safe treatment, and should ideally exceed 10 milliseconds to avoid thermal injury to the epidermis, yet be shorter than the hair follicle’s cooling time (estimated at 40-100 microseconds) after each pulse to allow it to quickly cool off afterward, eliminating potential epidermal damage.

Underarm treatments are another highly-requested area, and a 3 cm2 spot size is perfectly suitable for laser hair removal treatments here. This larger surface area allows practitioners to more quickly treat multiple hair follicles here than would be needed with electrolysis, saving both time and money in terms of treatment completion time.

Laser hair removal has quickly become one of the most in-demand aesthetic treatments, and as demand continues to soar it is vital that practitioners have access to appropriate tools in order to meet patient needs safely and effectively. Laser power, pulse width, and spot size all play key roles in determining treatment outcome.

Larger laser spot sizes enable practitioners to treat large body areas more quickly, thus shortening treatment time and improving patient comfort, particularly important when treating sensitive skin types. Furthermore, larger spot sizes facilitate photon recycling and deeper penetration of laser energy; one study discovered that an 18 mm spot size provided superior results in axillary hair removal.

Smaller spot sizes are better for treating superficial hair follicles, while larger spots work best for treating deeper ones. When considering pulse length and spot size in relation to fine hairs (which heat quickly but cannot maintain temperature stability), shorter pulse widths that range between 5-10 milliseconds is usually required; thicker hair requires 40-60 ms pulse widths instead.

Fluence and spot size must work in concert for maximum efficacy. While higher fluences may increase effectiveness, they may also cause perifollicular erythema and edema. A test patch can assist practitioners in selecting an optimal fluence for each skin type and hair color combination.

The trio laser hand piece combines three of the most effective wavelengths for laser hair removal: ruby (694nm), alexandrite (755nm) and diode (800-1,000nm). This multi-wavelength approach optimizes treatment by targeting different anagen and telogen phases; in particular, 755 nm wavelength targets both bulge/papilla of hair follicle as well as longer wavelengths that target hair shaft; providing comprehensive solutions across face/neck area, bikini area legs/back – helping clients say good bye to shaving/waxing/plucking forever!
