Itchy Legs After Laser Hair Removal

Undergoing a laser hair removal treatment is an effective way of removing hair, but also for preventing future hair growth. The treatment utilizes specialized laser light to kill the hair follicles, which causes existing hair to fall out while stunting further growth. The laser does not damage the tissue surrounding these hair follicles, but your skin may react to this treatment. To keep your skin healthy after laser removal of your hair, use these simple tips to care for your skin.

Laser treatments are most commonly used for your:

  • face
  • chest
  • armpits
  • back
  • bikini line
  • legs

A 2020 research reviewTrusted Source showed that advances in long-pulsed lasers have made it possible for this treatment to address not just dark hair on light skin as in the past, but also darker skin tones, too. Your physician will determine the best lasers to use based on both your hair and skin colors, as well as your hair texture.

It is a perfectly normal reaction for the skin to itch after laser hair removal. Certain areas might be more sensitive than others e.g. the bikini line area or legs. In particular if you have also suffered from ingrown hairs it may be those areas which are particularly itchy. 

It is extremely important you do not scratch the area as this may result in scarring. Instead, ensure to use a product to help calm the skin and promote healing. Sudocream has been particularly useful at this as it contains zinc. This is the more cost-effective solution. You can also combine this or instead use After Inked lotion which is used after procedures like tattoo removal where the skin can flareup. After Inked is a high-quality formulation which will ultimately promote rapid healing – just what you need after laser hair removal. You should find that the skin calms down within a week of the treatment. If however the itching persists consult with your laser practitioner or pharmacist.

  • increased swelling
  • burns or blisters
  • pain that doesn’t respond to your prescribed antiseptic cream
  • symptoms of pigmentation changes or scarring
  • symptoms of infection, including pus and red or discolored streaks

How To Treat Rash After Laser Hair Removal

Simply maintain your composure and seek medical assistance right away if you experience any allergic reaction symptoms, such as hives. It’s also best to be ready and expect hives to occur even before it does if you’re already prone to allergies and decided to push through with the treatment.

If you get severe hives, you may choose to totally forgo the remaining treatment sessions, subject to your doctor’s advice.

You can follow the suggested procedures for a quicker recovery and reduced itching after you immediately address any adverse reactions. You can also ask your doctor if any follow-up sessions for the treatment of your hives are advised, depending on the severity of the allergic reaction.

How Long Does Itching Last After Laser Hair Removal

Itching: This is a typical histamine response to the medication and should go away 24 to 48 hours following therapy.

Skin pigmentation: Following therapy, skin may become lighter or darker. Sun exposure affects this, so avoid the area for six weeks before your treatment if at all possible.

Skin pigmentation can be a common concern for many individuals, whether it be due to sun exposure, aging, or certain medical conditions. Following therapy, such as laser treatments or chemical peels, the skin may react by becoming either lighter or darker in color. This change in pigmentation is often temporary, but it is important to take precautions to minimize the risk of further complications.

One key factor that can influence changes in skin pigmentation following therapy is sun exposure. Ultraviolet (UV) rays from the sun can cause the skin to produce more melanin, the pigment responsible for skin color. This can lead to hyperpigmentation, or darkening of the skin, in areas that have been treated. To prevent this from happening, it is recommended to avoid sun exposure to the treated area for at least six weeks before and after your treatment, if possible.

In addition to avoiding sun exposure, there are other steps you can take to help maintain an even skin tone following therapy. Using sunscreen with a high SPF, wearing protective clothing, and seeking shade during peak sun hours can all help to protect your skin from further damage. It is also important to follow any post-treatment care instructions provided by your healthcare provider to ensure optimal results.

It is important to note that the risk of changes in skin pigmentation following therapy can vary depending on the type of treatment and individual factors. Some individuals may be more prone to hyperpigmentation, while others may experience hypopigmentation, or lightening of the skin. Consulting with a dermatologist or skincare specialist before undergoing any treatment can help to minimize these risks and ensure the best possible outcome.

Overall, taking precautions to protect your skin from sun exposure before and after therapy can help to minimize changes in pigmentation and promote healthy, radiant skin. By following these guidelines and seeking professional advice when needed, you can achieve the desired results from your treatment while maintaining the health and appearance of your skin.
