LED Therapy Explained
LED therapy involves exposing the skin to varying wavelengths of light. Each wavelength penetrates the skin at different depths and targets specific skin concerns. Unlike other treatments like laser therapy, LED therapy is non-thermal and does not cause damage or discomfort to the skin, making it suitable for regular use.
LED therapy devices typically emit light in blue light (around 415 nm) that targets acne-causing bacteria and helps treat active breakouts. It also emits red light (around 633 nm) that stimulates collagen production and helps reduce signs of ageing and near-infrared light (around 830 nm) penetrates deeper into the skin to reduce inflammation and promote wound healing. Yellow Light (around 590 nm) is also a product of this therapy and is often used to reduce redness and improve skin tone.
Why Is LED Therapy Beneficial?
LED therapy offers several key benefits for your skin, including:
- Reducing Acne: Blue light penetrates the skin’s surface and targets Propionibacterium acnes (P. acnes), the bacteria responsible for acne. By killing these bacteria, blue light reduces breakouts and inflammation.
- Anti-Aging Effects: Red light therapy helps stimulate collagen and elastin production, two proteins essential for maintaining firm and youthful-looking skin. Regular use of red light can reduce fine lines, wrinkles, and improve overall skin texture.
- Even Skin Tone: Yellow and red lights can help reduce redness, hyperpigmentation, and rosacea by calming inflammation and improving skin tone.
- Improved Skin Healing: Near-infrared light aids in wound healing and reduces scarring by promoting cellular repair and increasing circulation in the skin.
- Reducing Puffiness and Dark Circles: Some studies suggest that LED light therapy, particularly red light, may help reduce puffiness and dark circles by improving blood flow and reducing inflammation.
LED Devices for Your Home Use
There are different LED therapy devices available for your home use. They range from handheld wands to full-face masks.
The most common types are:
- LED Face Masks: These masks cover the entire face and typically offer multiple colour settings to treat a range of skin concerns. They are convenient because they provide uniform treatment over a large area.
- Handheld LED Devices: These portable devices allow for more targeted treatment on specific areas, such as acne spots, wrinkles, or dark patches. They are typically smaller and easier to use for localized concerns.
- LED Light Panels: These are larger devices that can treat both the face and body. They are usually mounted on stands or walls and are often used for more extensive treatments like reducing body inflammation or accelerating the healing of larger areas.
How to Use LED Therapy at Home
Using LED therapy at home is simple. But to achieve optimal results, it’s important to follow certain guidelines.
Step 1: Cleanse Your Skin
Always start with a clean face. Wash your skin using a gentle cleanser to remove any dirt, oil, or makeup. This will ensure that the light penetrates your skin effectively and that no residues block its absorption.
Step 2: Apply Serum (Optional)
Depending on your skin goals, applying a serum before the LED treatment can boost results. For example, a hyaluronic acid serum can hydrate the skin, while a vitamin C serum can brighten and protect. Make sure the serum you choose is compatible with LED light. Avoid serums that contain retinoids or other ingredients that might increase light sensitivity unless instructed by a dermatologist.
Step 3: Use the LED Device
Follow the manufacturer’s instructions for your device, as different models may have varied usage guidelines.
Turn on the device and choose the appropriate light setting: If you are treating acne, choose the blue light setting. For anti-aging, select the red or near-infrared setting. Some devices have preset programs that alternate between lights, allowing you to target multiple skin concerns in one session.
Hold the LED device or wear the mask as directed. Usually, this means positioning it about 1-3 centimetres from the skin or securing it directly onto the face, depending on the type of device. Ensure that the light covers the entire treatment area.
Most devices recommend using the LED light for 10-20 minutes per session, 3-5 times per week. Do not exceed the recommended time, as overuse may lead to skin irritation.
Step 4: Follow-Up Care
After the treatment, apply a moisturizer to hydrate your skin. If you use the device in the morning or daytime, don’t forget to apply sunscreen, as LED therapy can make your skin more sensitive to UV rays.
Conclusion
LED therapy is a versatile, non-invasive treatment that can help improve skin health, whether you’re targeting acne, ageing, or skin tone. With various at-home devices available, it’s easy to incorporate this treatment into your skincare routine. However, practice consistency and have your dermatologist in a loop to reap the best results.
