The quest to remain ageless and scar-free in skincare led to the development of another skin treatment called the Red Light Therapy (RLT). For those unaware of this procedure, it looks exactly the way it sounds and promises to stimulate collagen production and treat other skin conditions.

What is Red Light Therapy?

Red light therapy, also referred to as low-level laser therapy (LLLT) or photobiomodulation (PBM), is the intentional openness to near-infrared or red light. It is transported via light-emitting diodes (LEDs) or low-level lasers. 

It is a non-invasive therapy that can be used for various purposes like healing wounds, managing pain, growing hair, and maintaining good skin health. It works by absorbing light energy from cells, and this leads to enhanced cellular activity and improved energy production. 

Types of Red Light Therapy Devices

There are various types of red light therapy devices. They range from little handheld devices to larger panels. Some of the common types that you will find are:

  • Handheld Devices: These are compact devices that you can hold and apply to particular aspects of your body directly. They are usually used for specific treatments like fine lines on the face or joint pain in particular areas.
  • Panel Devices: These devices entail larger panels or a combination of LEDs that emit red light over a wider area. Panel devices are perfect for treating full-body and are usually used in professional settings or at home to oversee general skin health.
  • Body Pads: They are flexible pads that are entangled with red light LEDs.  They are often wrapped around particular body parts for localized treatment.
  • Lamps and Bulbs: Some red light therapy devices are also in the form of lamps or bulbs that are used for standard lighting. They permit widespread usage of red light in a room.
  • Masks: A red light therapy mask is created to be worn over the face. It offers a specific treatment for skin issues like acne, wrinkles, or general skin refreshing.

Can I Do Red Light Therapy at Home?

Yes, it is possible to do red light therapy at home. There are lots of devices created for this purpose, so you can pick one up for your personal use. However, before you begin this all by yourself at home, you need to consider the following factors:

  • Select a device that suits your particular needs or the aspect that you intend to treat.
  • Ensure that you adhere to the manufacturer’s instructions to ensure that you remain safe all through.
  • Stick to the recommended treatment time frame and frequency without doing the contrary.
  • To get desired results, ensure that you remain consistent and remember that patience is key.
  • In case of any issues or concerns, consult with a healthcare professional for advice or solutions.

Certainly! Red light therapy is beneficial for different purposes. However, the reaction of each person differs. So, you need to be deliberate and study your usage process to determine whether it is really working for you or not.

Can Occlusion Patches Increase the Skin Benefits of Red Light Therapy?

Occlusion patches help to create a barrier on the surface of the skin. They are usually not used with the red light therapy treatment. While red light therapy depends on the penetration of light into the skin to become effective, using an occlusive patch at the same time can deter light penetration. These patches are usually a part of skin care products and are used to boost the absorption of the applied product into the skin.

Therefore, if you are considering combining red light therapy with other skincare products, ensure that you follow the specific suggestions for each treatment.
