Can a dark spot appear after laser hair removal?

It is possible to get dark spots after LHR (laser hair removal). This could be PIH which means post inflammatory hyperpigmentation. This is a dark mark resulting from inflammation. This typically is not permanent but could also take a very long time to go away. It is very important to protect these dark areas from the sun, because the sun will cause them to darken. There are creams as well as other lasers that can sometimes help improve these dark marks.

Any type of laser treatment can cause hyperpigmentation. Ensuring that your treatments are being done by a licensed and well-trained professional as well as following your provider's pre and post-care instructions can help minimize the risk.  

Laser hair removal picks up on pigment which is why it is important you are not tan when you do the procedure. It will pick up the melanin in your skin which causes a risk of burning and not getting the hair follicle. Depending on your skin tone, this risk of burning increases your risk of hyperpigmentation from burning. I hope this helps!

Hello! Yes, hyperpigmentation can occur after laser hair removal and is usually temporary. In some cases, lightening creams can help resolve it quicker. The darker your skin tone, the more likely this is to occur. Hope that helps!

Hyperpigmentation should not happen after laser hair removal, if the correct wavelength is used that is appropriate for your skin type. The only other instance when hyperpigmentation could occur is when there are residual oils or lotions etc on the skin which can hyperconcentrate the beam. It is essential to cleanse the skin with mild alcohol to remove oils and air dry before any treatment.

Thank you for your inquiry.
The short answer to your question is yes--LHR can indeed cause hyperpigmentation. This is often due to incorrect settings being used for the appropriate Skin tone/color (eg. higher risk in Fitz 4-6 skin types). Additionally, this can happen with older LHR devices. The newer technology, like DIolaze XL by InMode Aesthetics (available with their different devices), has a built-in cooling mechanism that helps to prevent over heating of the skin. The technology also targets the follicle very specifically if done with the correct settings for the appropriate skin tone.
Depending on the severity of the hyperpigmentation, your provider should recommend and/or prescribe a skin care product that can help address this as soon as possible (eg. Hydroquinone). Future treatments should be temporarily put on hold until the hyperpigmentation resolves. You should discuss the treatment settings with your provider to ensure that he/she used the appropriate settings and considers decreasing the energy settings to avoid any recurrences. With decreased energy setting(s), you may need more treatments to achieve your desired outcomes; but in the end, this will ensure your safety and minimize and/or avoid any hyperpigmentation recurrences.
Best of luck.
