A Skin So Dark Absorbs A Laser So Light
Having a dark skin color in laser treatment may need you to have lower energy options and extended pulses and wavelengths, including a cooling procedure that is also extensive. Previously, those who were producing lasers would think that this will not benefit those ethnic individuals and just left them unnoticed. Today, we now utilize laser technologies that are both effective for light and dark skin toned individuals. In the States, we have a great number of people who has this color of skin.
It has become internationally famous because of the laser producers who would concentrate more on dark skinned persons. In the epidermis of men and women with dark colors, they have more melanin in them and melanized melanosomes which makes the lessening of melanin little. Having darker skin color may help you in taking up and spreading UV light which causes photo protection. With that, dark toned individuals can avoid skin cancer, wrinkles and photo damage than those light skinned ones.
On the other hand, the mesenchymal activity in the dermis of dark toned individuals is great which means that there is a greater chance that they might have hypertrophic scars. The melanin of darks colored people are more compared to Caucasian, and if the same setting is used in them, then they can absorb more energy through it. Certain illnesses like depigmentation, hypopigmentation and hyperpigmentation is possible if this happens.
To be able to not let these happen, a physician must utilize cryogenic sprays, ice pack and gel pack once the treatment is done or before it can happen. If ever the procedure is in process or it is done, then the most effective way of cooling is the contact cooling, for this cool down an area in the skin even when the treatment is going on. When it comes to such machinery, they rely not only on water based elements.
This can make a parallel cool as well as distribute the pulse that is running along the sapphire crystals that makes the epidermis cold. Individuals with a dark color can have the treatment with a low rate of energy but this is not very efficient when done. Cooling can benefit us is two ways, it can help in lessening specific damages and it gives us the chance to use energy at a greater rate.
The safest option for dark skinned patients in hair removal is a 1,064 nm Nd:YAG lasers and intense pulse light with 500nm to 1,200 nm in range. Hair removal treatment causes the melanin to be lessened out but with a 1,064 nm laser the absorption of it is low. And so the dark skinned ones really have the gain to it.
A setting of 40 m for the pulse is used for those with ethnic skin tone and 10 ms to 20 ms are used for those Caucasians. If a dark skinned patient would utilize a bleaching cream before his treatment, then it will result in the reduction of the melanin. Ensure that you put sunblock if you have utilized bleaching creams before and after each laser treatment.
These kinds of mechanisms can be used not only for hair removal but also for other treatments such as photo rejuvenation, tattoo removal and even skin resurfacing. Up until now, certain laser and light technology manufacturers are increasing various ways for this to be able to be used at maximum by those with a darker complexion. The development of such laser and light technologies will of course carry on.
