LED Yellow Light Therapy

What is LED Yellow Light Therapy?

LED yellow light therapy (wavelength approximately 570–590 nm) uses light-emitting diodes to produce low-coherence, low-power yellow light. This light can penetrate the epidermis and act on the superficial dermis, where it is primarily absorbed by hemoglobin and cytochrome C, promoting microcirculation and cellular repair.

How Does LED Yellow Light Therapy Work?

LED yellow light therapy enhances mitochondrial activity within cells through gentle light energy, stimulating the production of ATP. Increased ATP levels lead to accelerated fibroblast proliferation and collagen synthesis, improving skin elasticity and firmness. Yellow light also helps dilate microvessels and improve local blood flow, reducing skin redness and swelling. Since the treatment does not disrupt the skin barrier, there is no significant downtime, and most patients can return to normal activities immediately.

Key Benefits of Yellow Light Therapy:

• Reduces Redness and Inflammation: Anti-inflammatory properties help soothe sensitive and flushed skin.

• Improves Pigmentation: Helps fade sunspots, post-inflammatory hyperpigmentation, and melasma.

• Relieves Lymphedema: Enhances lymphatic drainage, which can reduce lymphatic swelling.

• Improves Skin Barrier Function: Strengthens the natural skin barrier, increasing resistance to external irritants.

Penetration Depth:

The effective depth of yellow light is primarily between 0.2–0.5 mm, reaching the superficial dermis. This makes it effective in regulating skin microcirculation, immune cells (such as mast cells), and fibroblast activity.
