The application of specific wavelengths of red light is a non-invasive, safe procedure. People who are looking to achieve young, healthy skin or those who wish to experiment with an alternative treatment have become more interested in red light therapy. Its many benefits are well known - it reduces inflammation, increases blood flow and promotes cellular regeneration. The red light therapy improves the health of your skin and body by enhancing your overall health.
Although most people are in favor of its benefits, the question that is asked frequently is: Does lotion block red-light therapy? Yes, it is possible. Prior to undergoing red light therapy, it is best to have clean and bare skin. The results can differ due to the ingredients used in lotions. Some lotions can slow down the penetration through the skin of light, while others have no significant effect. This article explains how different lotions can affect red light therapy, and what you should consider before applying anything to your skin.
What is Red Light Therapy?
The skin is exposed to precise wavelengths of red and near infrared light. The therapy is non-invasive and drug-free. The wavelengths first radiate on the surface of the skin before penetrating deep tissue layers to activate natural healing mechanisms.
The red light therapy energizes mitochondria, the energy-producing cells that produce adenosine Triphosphate (ATP). [1] ATP, the cellular currency of energy, powers vital cellular functions such as repair and renewal.
Red light therapy promotes mitochondrial function by increasing ATP production. Red light therapy increases blood flow and oxygenation of cells, especially traumatized ones, to promote faster healing.
Red light therapy also relaxes your immune system, by reducing inflammation and oxidative stresses, which are both associated with many diseases. It reduces pain naturally and increases the synthesis and production of important proteins such as collagen, elastin and hormones such as melatonin.
Red light, unlike UV radiation does not damage or burn the skin. It stimulates natural healing through increased blood circulation and new cell growth. The red light therapy is used for a variety of purposes, including skin care, muscle repair, and pain reduction.
What Research Says
Although there are few direct clinical studies on the use of lotions to block red light therapy, research on photobiomodulation highlights the importance of unobstructed delivery of light to the skin to achieve optimal mitochondrial stimulation. Topical barriers such as oils and occlusive agents can absorb or scatter light, which reduces penetration depth. [4] In a study of low-intensity lighting, it was found that clean skin surfaces allowed for a better absorption of cytochrome C oxidase by mitochondria. This enhanced cellular energy processes.
In trials, skin-bare application consistently improved collagen synthesis and reduced inflammation.
What are the different types of lotions and their ingredients?
Lotion is used to soften and comfort the skin. Its main function is to replenish the moisture in the skin. There are many types of lotions. Each has a specific function and also differs in composition. Here are some examples of common types:
Moisturizing Lotions
These moisturizers are made up of ingredients like hyaluronic acids, shea butter, and glycerin. These moisturizers can form a thin barrier on the skin that protects it from environmental pollutants. However, this layer will also reduce light absorption.
Anti-Aging Lotions
These products are used to get younger, firmer and smoother skin. These products contain active ingredients like retinol and antioxidants. Some can absorb light energy but most are safe if they are absorbed completely before red light therapy. Serums and red-light therapy is a great article to learn more.
Prescription or Medical Lotions
They are used for conditions like fungal infections and burns. These can contain steroids, antifungals or other active medications that can either form a barrier to red light or inhibit its absorption depending on their composition.
Cosmetic or Fragrance Lotions
You can also apply it to your skin to give it a temporary glow. These products include silicones, dyes and perfumes. They can either reflect or absorb red light.
Does the use of lotions affect light penetration?
Some lotions can affect the penetration of the red light into your skin. Red light therapy is only effective if the right amount of light reaches deep into tissues. Light penetration can be affected by lotions, whether they are thick or thin.
Some lotions can absorb or scatter light, before it reaches the deeper layers. The lotions that contain heavy oils, sunscreens or reflective substances like zinc oxide, can block or reduce light absorption significantly. However, lightweight lotions that quickly absorb might have little or no impact.
In most cases it's best to remove any lotion before red light therapy. The low-waves of red and near infrared lights can penetrate your tissues more easily when you have bare, clean skin.
Do you need to use lotion before, after, or during red light therapy?
Many people ask if you should use lotion before or during red light therapy. You shouldn't use lotion during or before red light therapy. It will create a barrier which prevents the light from reaching your skin.
If you choose to do so, the best time to apply lotion is right after your session. The benefits of the light will be absorbed into your skin more quickly. Those with dry skin may need to apply lotion afterwards. This will keep their skin moisturized and smooth. A soothing, moisturizing cream can calm the skin without affecting the efficacy of the therapy.
Some lotions may block red light.
You should not use certain lotions before using red light therapy. They will absorb most of the near-infrared and red light. Below are some examples of lotions that reduce or block red light penetration.
Sunscreen lotions that contain physical sunblocks, such as zinc oxide or titania dioxide, will reduce red light absorption by a significant amount. Mineral oil, petroleum jelly, or lanolin, are all heavy oils that leave a greasy layer on the skin. This prevents light from reaching deeper tissues.
Avoid cosmetic lotions containing silicone or fillers, as they can reflect light and create a barrier to the skin. Use any prescribed medical lotions before applying them.
Best Practices in Red Light Therapy
Follow these simple steps to get the best benefit from red light therapy:
Cleanse and dry your skin
Before treatment, wash your face or body. Remove any lotion, makeup or oil, as well as sunscreen and other products from your skin. When your skin is clean, light can penetrate deep into the tissues of your body without disruption.
Remove clothing from the treatment area
Exposed the area that you wish to treat. The red light cannot penetrate clothing so it is necessary to expose the area.
Standing at the Right distance
If your device's instructions do not specify otherwise, place your body between 6 and 12 inches from the light source. This distance allows the light to safely and effectively reach your skin.
Be Consistent
Treat with red light between 3 and 5 times per week for optimal results. Session length can range from 10 to twenty minutes depending on the condition of your skin and the equipment used. When is the best time for red light therapy?
Avoid Lotions Before Therapy
Lotions block light. After your treatment, you can moisturize your skin to calm it and hydrate it.
Protect Your Eyes (If Necessary)
Some red light devices can be very powerful. Cover up your eyes with protective goggles when treating near your eyes. This is especially important if you have sensitive eyes. Find out more about red light therapy eye safety.
Conclusion: Should you use lotion or not?
Can applying lotion to the face block red light therapy?
Applying lotion to the face may create a thin layer of skin which can block or reduce the efficiency of the red and near infrared lights. If you're using red light therapy for smoother, firmer skin, avoid lotions before. This is true especially for lotions containing silicones, oils or sunscreens like zinc oxide. For best results, always remove any lotion from your skin before beginning the therapy.
