Diode (808) Laser Hair Removal The Diode wavelength is very effective on darker skin tones but is less effective on lighter, finer hair. Its deep penetration levels offer the best results for skin types I to IV.
Lasers such as ruby (694 nm), alexandrite lasers (755 nm) for lighter skin types, Nd: YAG (1064 nm) for darker skin types and diode lasers (800-810 nm) for all skin types I-VI are effective. All these lasers work by using selective photothermolysis, where melanin in the hair follicle is the chromophore.
The diode laser produces high-intensity coherent light to provide non-invasive treatment for vascular issues and pigmentation problems. It is very effective in treating sun damage, benign growths and larger vascular lesions.
Materials that cannot be cut on a laser cutter include metals with high reflectivity (like copper and aluminum), materials containing PVC (polyvinyl chloride), and certain types of glass and reflective surfaces.
Best known and used application is permanent hair reduction, however they are also suitable for rejuvenation, treating scars, small vessels and pigmented lesions with a favorable safety profile.
Approximately 10% of the patients reported mild pain or minor adverse events. Ninety-eight percent of the patients were satisfied with the treatments. Conclusion: Treatment with a diode laser (810 and 940 nm) is safe and may be effective for facial skin tightening.
Most patients can have laser hair removal once every 4 to 6 weeks. Your dermatologist will tell you when it is safe to have another treatment. Most patients see some hair regrowth. Your dermatologist can tell you when you can safely have laser treatments to maintain the results.
One of the biggest disadvantage of a diode laser is a beam quality. Most of quite powerful laser diodes with optical power more than 1000 mW (1W) have a pretty low beam quality that make it difficult to focus.
We have had some customers get through the pink with many slow passes, but the edges tend to be rough. As a general statement, we do not recommend the pastel pink acrylic for diode lasers.
Is Diode Laser Hair Removal Permanent? Diode laser hair removal can be permanent following a course of treatment customized to your needs and hair type. Since not all hair is in a growth phase at the same time, it may be necessary to revisit certain treatment areas to permanently remove hair.
Diode lasers are more effective for permanent hair reduction & pigmentation removal. IPL lasers emit multiple wavelengths of light that scatter and penetrate the skin at various depths, targeting different chromophores like melanin, hemoglobin, and collagen.
The laser energy used in the procedure can disrupt the production of melanin in the skin, leading to hypopigmentation or lightening of the treated areas.
Patients may expect redness, skin irritation, erythema, postoperative hypersensitivity and possible burns manifested by blisters and scabs. It is also possible to experience pigmentary changes such as hyperpigmentation.
Long hair can cause discomfort during the laser hair removal process. It can get caught in the device or create additional friction, leading to an unpleasant experience. Shaving before the diode hair laser treatment ensures a smoother, more comfortable procedure by eliminating this potential discomfort.
Hyperpigmentation: When the laser targets the hair follicle, the high heat can sometimes stimulate the melanin-producing cells in the surrounding skin, causing them to produce more melanin than usual. This can result in hyperpigmentation or darkening of the skin in the treated area.
A diode lazer will never cut through clear acrylic and it's extremely difficult to cut white and bright blue acrylics without doing the whole melt instead of cut thing, because the blue light of your lazer struggles to pass through these colors.
Yes! You can laser cut EVA foam (Ethylene-Vinyl Acetate foam).
Advantages of Diode Lasers
They're particularly effective for engraving on materials like wood, plastic, leather, and acrylic. Diode lasers' precise focus also allows for detailed engravings, making them ideal for intricate designs.
What Are the Disadvantages of a Diode? Though diodes can protect electrical circuits, their efficiency is comparatively low. Their voltage drop is ~0.7V, so they use power even when there is no current flow. The low efficiency makes diodes unideal for electrical circuits that need high efficiency, such as solar cells.
In the U.S., it is legal under federal law to own a laser of any power. But often people talk about “illegal laser pointers”. This is somewhat confusing shorthand meaning that the manufacturer or seller illegally called a laser above 5 milliwatts a “pointer”, or illegally promoted it for pointing purposes.
Diode lasers are generally more effective for a broader range of skin types, including darker skin, while IPL works best on lighter skin with darker hair. For larger areas, IPL might be a more time-efficient choice. Diode lasers are often preferred for smaller, more targeted areas.
It is recommended to wait 24 hours before showering after laser hair removal to allow your skin to heal. However, if you must shower before this time, wait at least 8 hours and take a cold shower to minimize irritation or other skin reactions.
The degree of discomfort experienced during diode laser treatment can vary depending on the area being treated, as well as the individual's pain threshold. Generally, most patients experience some level of discomfort, but it is usually mild and tolerable.
