Which is better, blue or red light therapy?

Sommario

The choice between Blue Light Therapy (BLT) and Red Light Therapy (RLT) depends on your specific goals, as they address different issues. Here’s a head-to-head comparison to help you decide:

Blue Light Therapy (415-450nm) Best for:

√ Acne TreatmentKills P. acnes bacteria (FDA approved for mild to moderate acne).

√ Oily Skin ControlTemporarily reduces sebum production.

√ Psoriasis/Eczema SupportCalms inflammation when combined with red light.

Limitations:

× No anti-aging benefits (does not stimulate collagen).

× May dry out skin (not ideal for sensitive or dry skin types).

× Only superficial (penetrates 1-2mm).

Best for: Teens/adults with acne, oily skin or scalp conditions.

Terapia della luce rossa (630-660nm, 850nm NIR) Best for:

√ Anti-AgingIncreases collagen & elastin (reduces wrinkles, improves skin firmness).

√ Wound HealingSpeeds recovery from scars, burns or post-surgery treatments.

√ Pain & Inflammationrelieves joint and muscle pain (artrite, tendonitis).

√Hair GrowthFDA approved for androgenetic alopecia (e.g. iRestore).

Limitations:

× Doesn’t kill acne bacteria (use blue light for active breakouts).

× Slower results (requires consistency: 8-12 weeks for collagen benefits).

Best for: Aging skin, chronic pain, hair loss or general recovery.
