Red Light Therapy vs Blue Light Therapy

Red Light Therapy

What It Is: Red light therapy (RLT) involves exposing the skin to low levels of red or near-infrared light. This light penetrates the skin to a depth of about 8-10 millimeters, reaching deeper layers of the skin and tissues.

Skin-Related Benefits:

1. Improves Skin Tone and Texture:

   • Stimulates collagen production, resulting in smoother and firmer skin.

   • Enhances skin elasticity and reduces sagging.

2. Reduces Wrinkles and Fine Lines:

   • Helps diminish the appearance of fine lines and wrinkles by boosting collagen and elastin production.

3. Scar Reduction:

   • Promotes faster healing and diminishes the appearance of scars, including acne scars and surgical scars.

4. Reduces Inflammation and Redness:

   • Decreases inflammation in conditions like rosacea, eczema, and psoriasis.

   • Helps soothe irritated skin and reduces redness.

5. Improves Overall Skin Health:

   • Enhances cell regeneration and turnover, leading to healthier, more radiant skin.

   • May reduce hyperpigmentation and age spots by promoting even skin tone.

Blue Light Therapy

What It Is: Blue light therapy involves the use of blue wavelength light (typically around 405-450 nm) to treat various skin conditions. This light affects the surface layer of the skin.

Skin-Related Benefits:

1. Acne Treatment:

   • Kills Propionibacterium acnes, the bacteria responsible for acne breakouts.

   • Reduces inflammation associated with acne, helping to clear up existing blemishes and prevent new ones.

2. Reduces Sebum Production:

   • Helps control the production of sebum (skin oil), which can reduce the occurrence of clogged pores and acne.

3. Treats Other Skin Conditions:

   • Can help manage conditions like psoriasis and eczema by reducing surface bacteria and inflammation.

4. Minimises Pore Size:

   • Helps reduce the appearance of enlarged pores by eliminating bacteria and reducing oil production.
