Red light therapy is widely used for skin rejuvenation, 炎症を軽減する, and improving skin tone. But for those with melasma—a condition that causes dark patches on the skin—many wonder: Can red light therapy make melasma worse?
What Is Melasma?
Melasma is a form of hyperpigmentation, often triggered by sun exposure, hormones, or heat. It usually appears on the cheeks, forehead, or upper lip and is more common in women.
Is Red Light Therapy Safe for Melasma?
In most cases, red light therapy is considered safe and gentle, even for people with melasma. It uses low-level red or near-infrared light that does not emit UV rays or intense heat—two known triggers for worsening melasma.
Can It Make Melasma Worse?
While uncommon, in rare cases, heat-sensitive skin may react to prolonged or high-intensity red light exposure. If the device emits too much heat, it might contribute to pigmentation in sensitive individuals. しかし, this is not typical with well-designed, low-heat red light therapy devices.
Tips to Avoid Risk
- Choose a high-quality, low-heat device.
- Start with short sessions (5–10 minutes) and monitor your skin.
- Use SPF daily, as red light therapy does not replace sun protection.
- Consult a dermatologist before starting if you have melasma or other pigment issues.
最終的な考え
Red light therapy is unlikely to make melasma worse and may even help reduce inflammation that contributes to pigmentation. Still, it’s important to use the right device and treatment plan, especially for sensitive or melasma-prone skin.
