What to Expect During Light Therapy Treatment on Acne Breakouts?
Before beginning your phototherapy sessions, you will consult a dermatologist. This is how they will determine whether you need to take these therapies or not.
Moreover, they’ll also inform you about what you will encounter before and following these sessions.
You may also be advised to stay away from retinol and other kinds of skincare products for at least two weeks before your light therapy treatment.
Moreover, you might also need to inform your dermatologist if you’re on anti-inflammatory drugs. They might also recommend you to avoid sun exposure (without applying sunscreen) or tanning beds during your treatment sessions.
Both red and blue light treatments typically last between 15 and 30 minutes. You will either be instructed to lie down or place the head on a special device to place your head on a special device that will keep your face stable throughout the session.
A trained light therapy specialist — generally a dermatologist will apply light pulses to various areas of your face in a circular pattern.
However, you may have some nervousness throughout these sessions, which is quite natural. Maintain as much calm and stability as possible to ensure that the sessions run smoothly.
Following these treatments, your skin may seem somewhat red or pink. However, these will fade away with time.
After the sessions, the skin may become even more sensitive, and if it happens you may need to call off the therapy sessions for a few days.
At certain times, your dermatologist may advise you to apply sunscreen every day which will help your skin from direct exposure to sunlight.
Moreover, it is highly improbable that you will require only one therapy session. Typically, it takes around two to even three sessions each week to begin, and this can last up to four to six weeks.
However, these therapies are often not covered by insurance policies and can cost up to $50 each session.
Does Blue Light Really Help With Acne Problems?
According to the AAD, blue light therapies are an excellent acne treatment. However, the results may vary across individuals and that acne may not be totally cleared. Moreover, a person will require multiple sessions, and benefits may not be visible for several weeks following the last treatment.
Numerous studies have discovered that this light therapy can be beneficial for those who suffer from acne.
A 2019 research showed that the majority of these research were modest in scope and none lasted longer than 12 weeks.
However, there are certainly no significant side effects with any of these therapies. So, you can easily undergo these therapies. We will still recommend you consult with your dermatologist first before going through these therapy sessions.
So far light therapy treatment has been successful at treating acne outbreaks. It is essential to have reasonable expectations about the effectiveness of this therapy. However, this therapy might be a great remedy to cure acne breakouts, but it won’t completely stop it from coming.
It’s highly recommended that you explore less costly acne treatments first before undergoing light therapy, and make sure to consult your dermatologist to decide whether or not you qualify for this type of acne therapy session.
