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 (415-450Nuevo Méjico) Best for:
√ Acne Treatment – Kills P. acnes bacteria (FDA approved for mild to moderate acne).
√ Oily Skin Control – Temporarily reduces sebum production.
√ Psoriasis/Eczema Support – Calms 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 de luz roja (630-660Nuevo Méjico, 850nm NIR) Best for:
√ Anti-Aging – Increases collagen & elastin (reduces wrinkles, improves skin firmness).
√ Wound Healing – Speeds recovery from scars, burns or post-surgery treatments.
√ Pain & Inflammation – relieves joint and muscle pain (arthritis, tendonitis).
√Hair Growth – FDA 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.

Blue light (10 min) → kills bacteria.
Luz roja (10 min after) → reduces redness + increases collagen.

For maximum benefit: Choose based on your primary concern or invest in a dual wavelength device.
Blue prevents infection → Red speeds up recovery (e.g. after microneedling): Omnilux Clear, CurrentBody LED Mask (combo wavelengths).Science-Backed VerdictBlue light is better for acne and oily skin.Red light is better for anti-aging, pain relief and healing.Combined = best for acne scars + prevention (studies show 77% improvement vs. 50% with blue alone).
