Namun begitu, sesetengah orang bimbang: can red light therapy cause hyperpigmentation or dark spots? This article explains what science says and how to safely use RLT to avoid unwanted pigmentation issues.
Bagaimana Terapi Lampu Merah Berfungsi
Terapi cahaya merah menggunakan merah (600–700 nm) dan inframerah dekat (800–1000 nm) panjang gelombang untuk menembusi kulit. Proses ini:

What the Research Shows
- Red and near-infrared light do not increase melanin production, so they generally do not cause hyperpigmentation.
