Hair analysis can reveal glucose levels in diabetic patients.
research The Therapeutic and Preventive Effects of Light‐Emitting Diode (LED ) for Post‐Inflammatory Erythema and Hyperpigmentation: A Pilot Study
830 nm LED light effectively treats and prevents skin redness and dark spots, while 590 nm LED light only helps prevent them.
research Sensitive bromatometric assay methods for finasteride in pharmaceuticals
Three cost-effective methods accurately measure finasteride in pharmaceuticals, better than current techniques.
