Understanding Hyperpigmentation of the Skin
Hyperpigmentation refers to dark spots or patches on the skin due to excess production of melanin. Melanin is the pigment that gives skin its natural color. Several factors can trigger hyperpigmentation, like sun exposure, hormonal changes, aging, inflammation, and more. The darkened areas usually appear on the face, hands, and other frequently exposed parts of the body.
What Causes Hyperpigmentation?
Common causes leading to hyperpigmentation include:
- Ultraviolet rays from the sun
- Hormonal fluctuations
- Inflammatory skin conditions
- Side effects from medications
- Skin injuries or trauma that trigger excess melanin
Risk Factors for Developing Hyperpigmentation
You may be at a greater risk of hyperpigmentation if you:
- Have a personal or family history of skin discoloration issues
- Have darker skin tones
- Live in a sunny or high altitude climate
- Are middle-aged or elderly
Types of Hyperpigmentation
There are many types of hyperpigmentation based on their specific causes or appearances. The most common forms are:
- Melasma: Develops as larger patches on the cheeks, nose, forehead, and upper lip, often from hormonal changes.
- Solar lentigines (liver spots): Caused by long term UV rays exposure leading to flat brown spots on the face, hands and décolleté.
- Post-inflammatory hyperpigmentation: Results from skin inflammation like acne, eczema, infections, etc.
Using LED Light Therapy for Treating Hyperpigmentation
LED light therapy delivers beams of different color wavelengths deep into the skin to boost collagen, reduce inflammation and inhibit excess melanin production. This helps improve several skin issues, including uneven pigmentation.
What is LED Light Therapy?
Light emitting diode (LED) skin therapy uses powerful light beams to trigger beneficial responses in the skin for anti-aging and restorative benefits without heat damage or pain.
These light emitting diodes emit low level light at specific wavelengths tailored to improve various skin concerns like wrinkles, blemishes, dullness and discoloration.
Benefits of Using LED Light Therapy
LED light masks offer an easy, convenient, affordable and effective hyperpigmentation and anti-aging treatment from home. Benefits include:
- Boosts collagen production, increasing skin firmness and elasticity
- Minimizes the appearance of fine lines, wrinkles and crow's feet
- Reduces inflammatory skin reactions
- Destroys acne causing bacteria, improving breakouts
- Fades and evens out dark spots and skin discoloration
- No harsh chemicals, discomfort, downtime or adverse effects
LED Wavelengths Used in Light Masks
LED masks provide different light wavelengths, including:
- Blue light: Reduces breakouts and inflammation
- Green light: Boosts elastin protein, improves skin texture
- Yellow light: Brightens and balances skin tone
- Red light: Increases collagen, reduces wrinkles and scars
Do LED Masks Really Work to Treat Hyperpigmentation?
Several clinical studies confirm using LED therapy effectively targets pigmentation issues and provides results. Research shows:
- Up to 75% improvement in melasma in trials after four weeks using a certain wavelength LED mask
- 83% of people noticed reduced uneven pigmentation and age spots after 28 days of red light therapy in a study
- 90% users reported more uniform skin tone and diminished dark spots in six weeks in another red light trial
LED masks have also been medically tested and deemed safe for home use by reputed entities like the ARAAM technology council.
What to Expect with Continued Use
While LED light masks benefits pigmentation fast, continued regular use provides:
- Gradual fading of hyperpigmentation over 4 to 8 weeks
- Better results when combined with other topical lightening products
- Prevention of older or new dark spots when used long term
- Lasting improvement in skin tone and discoloration issues
Usage Tips to Maximize Results
Follow these best practices when using your LED light mask:
- Cleanse and dry the skin thoroughly before a session
- Use treatments consistently 2 to 3 times per week
- Pair masks with vitamin C, alpha-arbutin or kojic acid serums
- Apply a broad spectrum sunscreen during daytime after treatment
- Use for at least 6 to 8 weeks for best hyperpigmentation correction
Are LED Masks Safe? Understanding the Risks
LED light therapy masks are considered very safe for most people for home use as directed. However, there are some risks and side effects to consider before trying light mask treatments.
Potential Short Term Side Effects
Some temporary reactions from LED masks may include:
- Mild redness, dryness, stinging or itching right after use
- Headaches or eye strain from prolonged exposure
- Herpes simplex virus reactivation in prone people
Long Term Safety Concerns
While most people can use LED light masks without issues, discuss with a doctor first if you have:
- Photosensitivity disorders or on certain medications making skin sensitive
- Skin cancer or pre-cancerous growths
- Recent facial procedures, implants or fillers
- pacemaker or internal medical device
Usage Cautions for Safe Treatment
Take these precautions when undergoing LED light therapy:
- Always read device manuals and adhere to manufacturer’s recommendations
- Shield eyes and avoid staring directly at the light
- Adjust settings carefully, starting with lowest intensity
- Test mask on smaller skin area first to check for reactions before full face treatment
Are LED Masks Effective for Hyperpigmentation?
Yes, research shows LED light masks can safely reduce the appearance of uneven skin tone, age spots, melasma and post-acne marks when used properly. Results continue to improve over time with regular use. LED masks boost skin renewal and cell turnover to fade discoloration at the source.
However, always exercise safety precautions, check contraindications and see best results over 6 to 12 weeks of treatment. Combine with SPF protection and topical lightning serums containing hydroquinone, vitamin C, kojic acid, etc for quicker correction of pigmentation.
FAQs
What is the difference between melasma, liver spots and post-inflammatory hyperpigmentation?
Melasma causes larger greyish brown patches often on the cheeks, forehead, upper lip and chin due to hormonal factors. Liver spots or solar lentigines are flat, small brown spots that develop from years of sun exposure. Post-inflammatory hyperpigmentation appears as spots or discoloration after inflammatory skin issues like acne, cuts, burns, etc.
How often should you use an LED mask to fade dark spots?
Experts recommend using your LED light mask consistently 2 to 3 times per week for at least 6 to 8 weeks to see significant improvement in hyperpigmentation and dark spots.
Can you use an LED mask if you have skin cancer?
No, you should not use LED light masks if you have active skin cancer or pre-cancerous growths unless cleared by your dermatologist, as it can potentially worsen the condition.
What topicals boost LED treatment for pigmentation?
Using topical skin-brightening serums containing ingredients like vitamin C, hydroquinone, alpha arbutin, azelaic acid, kojic acid, etc can help enhance the pigmentation clearing effects of LED light masks.
