LED Photodynamic Therapy (PDT) is a non-invasive skin care treatment that uses different wavelengths of LED light to address various skin issues. Each light color represents a specific wavelength and offers unique therapeutic benefits.
Different Light Colors, Wavelengths, and Effects:
1.Red Light (620-750nm)

-- Recommended Users: Ideal for those seeking to enhance skin firmness and address signs of aging, especially individuals over 30 years old.
2.Blue Light (400-495nm)
-- Effects: Effectively kills acne-causing bacteria, reduces skin inflammation, and regulates sebum production. Commonly used to treat mild to moderate acne.
-- Recommended Users: Suitable for individuals with acne, blackheads, or oily skin, especially teenagers or adults dealing with acne issues.
3.Green Light (495-570nm)
-- Effects: Calms stressed skin, reduces hyperpigmentation, and helps improve uneven skin tone. It is effective in fading dark spots, sunspots, and redness.

4.Yellow Light (570-590nm)
-- Effects: Promotes lymphatic drainage, reduces swelling and irritation, strengthens the skin’s immune system, and improves rough skin texture.
-- Recommended Users: Great for sensitive skin, those prone to redness, or individuals experiencing puffiness.
5.Purple Light (380-420nm)
-- Effects: Combines the benefits of red and blue light. It helps kill bacteria while promoting skin repair, making it ideal for improving acne scars.
-- Recommended Users: Perfect for those with both acne concerns and a need to reduce scarring.
6.Orange Light (590-620nm)
-- Effects: Boosts cellular activity, increases metabolic rate, helps rejuvenate the skin’s appearance, and improves dull or tired-looking skin.

Precautions:
-- Avoid Overuse: Each session should not last too long. It is generally recommended to limit usage to 10-20 minutes per session to avoid overexposure to light.
-- Combine with Daily Skincare: LED light therapy yields better results when used alongside appropriate skincare products such as moisturizers or antioxidant serums.
-- Eye Protection: Although LED light does not emit harmful UV rays, prolonged exposure to bright light can still affect the eyes. It's advised to wear protective goggles during treatment.
-- Pregnant Women: Although LED light therapy is generally considered safe, pregnant women should consult with a physician before use.
Recommended Users:
-- Acne Sufferers: Blue and purple lights are ideal for treating acne.
