The Alexandrite Laser emits focused gentle Power by using an alexandrite crystal. As the light passes through the alexandrite crystal, a beam of light 755 nm extensive is manufactured.
The long-pulse alexandrite laser was employed to deal with 34 men and women with telangiectasias on the encounter and legs who had mild skin varieties (Fitzpatrick skin varieties I–III). The perfect set of parameters to the remedy of telangiectasias within the legs and deal with were being uncovered being sixty ms, 89 J/cm2, and six mm, respectively, by modifying the heartbeat period, fluence, and spot size within a stepwise way Using the dynamic cooling gadget (DCD) set at 50 ms spray and twenty ms hold off. Twelve weeks after just one treatment method underneath these conditions, leg vessels have been reduced by sixty five%. On the other hand, regardless if the optimum parameters have been utilized, the long-pulse alexandrite laser was nonetheless ineffective in occluding wonderful crimson vessels more compact than 0.6 mm. This can be due to the minimal written content of oxyhemoglobin in modest purple vessels along with the very low absorption of oxyhemoglobin through the lengthy-pulse alexandrite laser, which ends up in epidermal harm prior to vessel harm.

Immediately after 4 treatment options, a toddler with mixed IH on her chest experienced about an 80% reduction in tumor color and volume. Hence, we think that the therapy of IH with mixed Chinese and Western medication might become a new way for long run study.
What's more, it had the ideal success for thick IH by using a thickness of two–5 mm.16,17 Now, the more well-liked and successful option for laser therapy of superficial IH is definitely the pulsed dye laser (PDL).25 Having said that, due to the further penetration depth and bigger fluence, the extended-pulse alexandrite laser is more effective in treating hypertrophic IH, although paired with a pores and skin cooling procedure to additional lower Negative effects.

The melanin in the epidermis incorporates a decreased absorption coefficient with the 755nm wavelength in comparison to oxyhemoglobin, decreasing the Unwanted side effects a result of the competitive absorption of melanin and further more maximizing the therapeutic influence with the very long-pulse alexandrite laser on vascular lesions, Despite the fact that the 755 nm wavelength isn't near the 3 main absorption peaks of oxyhemoglobin (418, 542, and 577 nm). A list of software of extensive-pulse alexandrite laser in vascular lesions can be found in Desk one.
ALEXANDRITE LASERCutting-edge know-how with the newest Innovative generation of 755nm fractional handpiece offers an outstanding brightening and melasma treatment method more than 130 dots (400um dimensions) safeguarding sensible skin and reducing the risk of PIH and hypo-pigmentation.
Acne keloidalis nuchae (AKN) shares many similarities with PFB regarding its pathogenic procedure. An early intervention with a extended-pulse alexandrite laser proved prosperous in stopping the onset of AKN, according to a future study involving 17 clients Using the affliction. All people demonstrated substantial softening from the lesions soon after 6 remedies, that has a indicate reduction in papule and pustule counts of ninety% and ninety eight%, respectively, and a discount in keloidal plaque size of 54.
The incidence of hyperpigmentation in individuals was sixteen% reduced than with the QS alexandrite laser, which may be related to the absence of photomechanical consequences Along with the very long-pulse alexandrite laser as well as the more compact place size (four mm). In A further comparative research, the extended-pulse alexandrite laser was utilized with a bigger place dimension (ten mm) and fluence. As compared to the PDL, 532nm QS Nd:YAG laser, and 532nm extended-pulse potassium titanyl phosphate (KTP) laser, the lengthy-pulse alexandrite laser did not clearly show a major therapeutic result and had the very best danger of hyperpigmentation.30
