How Long Does Bruising Last After Vbeam (And Why)?

Exact Answer: Up To Twelve Days

Vbeam falls under dry lasers that generally use an organic dye in the lasing medium in a liquid solution. The dye is mainly used for a wide range of wavelengths, often covering wavelengths as low as fifty nanometers to as large as a hundred nanometers.

Apart from the presence in liquid form, dye lasers are also readily available in the form of solid-state dye lasers. Whether a solid-state dye laser or a liquid solution dye laser is to be used depends on the field of application of the laser. One dye can also be replaced with another dye if the previously used dye does not obtain relevant results.

P.P. Sorokin, a Russian American physicist, and F.P. Schafer, a German physicist, discovered the dry laser independently in 1966. The basic principle of a dry laser mechanism is that it uses a gain medium with the help of an organic dye, which is rich in carbon. It is a soluble stain and is often fluorescent similar to the one used in highlighter pens. The dye is then mixed with a suitable solvent, which helps the molecules diffuse evenly in the entire liquid solution. Further, a high-energy light source is passed through the dye, which results in the oscillation of the light waves, and the observations are studied further.

Various chemicals can be used in a laser dye, depending on the wavelength of a particular dye. Some of the most common ones are rhodamine with a wavelength ranging from 540-680 nm, and it exhibits an orange color. Fluorescein is another chemical that exhibits green radiation with a wavelength of 530-560 nm. A chemical named stilbene has a wavelength falling between 410-480 nm and the color violet. However, most of the dyes are toxic and are also carcinogenic.

Sensitivity Level Of The Patient’s SkinTime For The Bruising To Heal
Less SensitiveThree to four days
More SensitiveTen to twelve days

The bruising occurred because the beam needs some time to heal. If a patient’s skin is susceptible, then the bruising can take around ten to twelve days to heal completely. In contrast, less sensitive skin generally heals within three to four days.

Dye lasers are beneficial and have many applications in various fields of study. Some of the most well-known applications are in astronomy in the form of laser guide stars. Atomic vapor laser is also widely used in isotope separation in different mixtures of atoms. Dye lasers are also used for manufacturing purposes in different parts of the world. Medical experts also utilize dye lasers in performing various scans on their patients. It also has a wide range of applications in the spectroscopy department.

The time is taken for the bruising to heal completely depends on the wavelength of the light used. High wavelength light sources will cause a more substantial bruising effect than low ones. The bruise is generally purple on the very first day. Medical experts also suggest taking a natural herb named arnica as it helps in reducing the bruising time. Pineapple extract also helps in healing the bruise faster. Artificial cosmetics can also be used to hide the bruise.

The benefits of dye laser therapy are many, but it also has some side effects and complications. The biggest threat is that it can lead to cancer which could prove to be fatal. Extended radiation exposure can be toxic and harmful to the individuals in close contact with the patient. Some patients have also complained about skin issues after the use of dye laser.


Overall, it can be concluded that dye laser is a process in which various dye solutions are used, and light rays are passed through the solution. The solution can be liquid or in solid-state. The experiment was first conducted in the year 1966. Several chemicals can be used in the process, depending on the wavelength.

On average, bruising caused due to laser therapy takes around ten to twelve days to heal if the skin is susceptible. Otherwise, three to four days are enough for the same. Various natural measures can be taken to reduce the healing time. In case of any discomfort, a medical expert should be consulted.
