Red light therapy is known for its skin-healing and anti-aging benefits—but some people ask: Can red light therapy cause hyperpigmentation?
The Short Answer: Unlikely
Red light therapy does not typically cause hyperpigmentation.
実際には, it may actually help reduce certain types of pigmentation caused by inflammation or skin damage.
Why It’s Considered Safe
- Red light uses low-level, non-UV light, which doesn’t stimulate melanin the way sunlight (紫外線) does.
- It works by boosting cell repair and circulation, not by increasing pigment production.
- Studies show it may help improve skin tone, reduce redness, and promote even pigmentation.
When to Be Cautious
Although rare, people with very sensitive or heat-reactive skin should:
- Start with short sessions (5–10 minutes).
- Avoid using it with photosensitive products like strong acids or retinol.
- Always wear sunscreen if using red light as part of a daily skincare routine.
Can Red Light Help Hyperpigmentation?
はい! Some users report improvement in post-acne marks, sun damage, and uneven tone over time. しかし, results may vary depending on skin type and condition.
最終的な考え
Red light therapy is generally safe and does not cause hyperpigmentation. It may even help reduce it when used correctly. If you have existing pigmentation issues, talk to a dermatologist for the best treatment plan.
