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:
青色光療法 (415-450nm) Best for:
√ Acne Treatment – Kills P. ニス細菌 (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.
レッドライトセラピー (630-660nm, 850nm近赤外) Best for:
√ Anti-Aging – Increases collagen & エラスチン (しわを減らします, 肌の硬さを改善します).
√ Wound Healing – Speeds recovery from scars, burns or post-surgery treatments.
√ Pain & 炎症 – relieves joint and muscle pain (関節炎, 腱炎).
√Hair Growth – FDA approved for androgenetic alopecia (例えば. 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.

ブルーライト (10 min) → kills bacteria.
赤信号 (10 min after) → reduces redness + increases collagen.
Healing after the procedure:
For maximum benefit: Choose based on your primary concern or invest in a dual wavelength device.
Blue prevents infection → Red speeds up recovery (例えば. after microneedling): オムニラックスクリア, 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).
