What is the maximum frequency which is safe for hair laser?

Diode, alexandrite and yag lasers work best. Also, it will take a series of treatments to get improvement. Please see an expert for an evaluation. Best, Dr. Emer.

Hi , Thanks for sharing your query here. It wont be an issue as laser's effects changes from person to person. Complete 8 sessions and following Maintenance session plays an important role in improving the results especially in facial hair since they are stubborn. Usually maintenance is required 3 times in a year. You can discuss about this to your provider. Good luck. 
 

Hello, there are several different laser machines on the market and the settings for each of them differ.  To say what setting is safe would be impossible without knowing which machine is being used, and seeing and treating your skin.  Most practitioners would start using a more conservative setting when first treating someone to see how their skin reacts.  If you had no irritation or pigmentation issues when being treated and the treatment was not effective than the energy should probably be increased.  Good luck!

Hello there, 
        LHR differs from provider to provider, from laser to laser, and from patient to patient. With your coloring, lower setting will definitely always be best utilized, but that does not mean that increasing the intensity slightly will cause issues. Typically LHR settings DO have to be increased from appointment to appointment since the hair gets thinner and harder to treat effectively with the same setting. If you have concerns, I would definitely discuss with your provider. Hope this helps.

Laser hair removal works on the principle of customizing the laser energy to match your skin type, and hair type. So, yes, it is okay to go up on the energy  to improve the results. For example, it is okay to use more than one mode, more than one wavelength, mix up the wavelengths, use different energies in different parts of the body and so on. The visual cue for the optimum energy in each session, is an end point - which can be follicular edema (swelling around the hair roots), to visible hair extrusion, to follicular erythema (redness). The end point is dependant on the device and the energy used. So yes, the energies will not be the same during each visit, and each visit would only be able to give you 10-20% reduction. More is possible and happens during the first few sessions, if the hair is very thick, but it is best to keep your expectations realistic.

Hello, thank you for your question.  The energy (joules) used will vary from device to device depending of the manufacturer of that device.  The energy will also be determined by the skin type (color of skin), as well as the wavelength being used.  Since you say that you have Indian skin, I would recommend that the (YAG) 1064nm wavelength be used on you.  This wavelength can be used safely on darker skin types.  It is necessary to complete the series of treatments in order to have success.  After the recommended series of treatments are performed, it may be necessary to do occasional touch up treatments.Good Luck!
